Meiosis is a type of cell division that reduces the number of chromosomes in the parent cell by half and produces four gamete cells. This process is required to produce egg and sperm cells for sexual reproduction.

Miosis

Diffusion is the process by which solutes are moved along a concentration gradient in a solution or across a semipermeable membrane. If the molecules are small enough, this simple diffusion can happen across cell membranes, between the individual phospholipids that make up the membrane.

Diffusion

What is it?: It is the gelatin-like fluid inside of the cell's membrane aka protoplasm Analogy: River Function: Nutrients are absorbed, transported and processed in the cytoplasm. It also gives the cell it's structure It is the site of many chemical reactions

Location: channels in Cell Walls Function: Allow communication and transport of materials between adjacent cells Analogy: Window between houses

Composed of two subunits, they can be found floating freely in the cell’s cytoplasm or embedded within the endoplasmic reticulum. Using the templates and instructions provided by two different types of RNA, ribosomes synthesize a variety of proteins that are essential to the survival of the cell. Analogy: The protein factory

If the proteins from the rough ER require further modification, they are transported to the Golgi apparatus (or Golgi complex). Like the ER, the Golgi apparatus is composed of folded membranes. It searches the protein’s amino acid sequences for specialized “codes” and modifies them accordingly. These processed proteins are then stored in the Golgi or packed in vesicles to be shipped elsewhere in the cell.

The endoplasmic reticulum (ER) is a membranous organelle that shares part of its membrane with that of the nucleus. Some portions of the ER, known as the rough ER, are studded with ribosomes and are involved with protein manufacture. The rest of the organelle is referred to as the smooth ER and serves to produce vital lipids (fats).

Location: Large fluid filled sac in the vacuole -Membrane bound -Much larger in plant cells Function: Stores water, food waste, starch, etc. -In plants involved in turgor pressure to make cell firm "warehouse"

Function for Nucleus: A large organelle that stores the cell’s DNA (deoxyribonucleic acid). The nucleus controls all of the cell’s activities, such as growth and metabolism, using the DNA’s genetic information. Function for Nucleolus: Within the nucleus is a smaller structure called the nucleolus, which houses the RNA (ribonucleic acid). RNA helps convey the DNA’s orders to the rest of the cell and serves as a template for protein synthesis. Analogy: The command center

-Bean shaped -has it's own DNA and membrane Function: Breaks down glucose to release energy (Apt, water and carbon dioxide) via cellular respiration -ATP is then used by the cell to carry out the other activities Analogy: Power house

Location: Internal framework of the cell It is made up of microfilament microtubules Analogy: Skeleton Function: Helps the cell keep it's shape

Function: Used for absorption of light -Only in plant cells -has it's own DNA and double membrane -Captures sunlight to produce glucose and oxygen (via photosynthesis) Analogy: Solar panels

Location: Surrounds the cell Function: Protects the cell and gives the cell shape Analogy: Castle Wall Found in: Only found in plant cells

They are parts that are found in cell

It' s telophase, in telophase the spindle disappears and a nuclear membrane re-forms around each set of chromosomes. The separated chromosomes reach the opposite ends of the cell. The nucleolus reappears

Cytokinesis is the last step. During this phase the cytoplasm divides and 2 daughter cells emerge

Anaphase starts with the sister chromatids of each chromosome separate from one another. The chromosomes move towards the opposite ends of the cell

Organelles in Plant and Animal cells

S Phase

Is Metaphase, during meta phase the chromosomes line up in the middle (Metaphase plate)

G2 Phase

Normal G1 cell functions occur as well as cell growth

Is Prophase, during prophase, the mitotic spindle starts to form , it is composed of centrosomes and microtubules. The nucleolus is gone and the chromosomes become condense and they appear as a sister chromatid

The G2 phase the cell continues to prepare for Mitosis and cell division

The S (Synthesis) phase DNA replicates, making exact copies of each chromosome

G1 Phase

A Process

In multicellular organisms, cell division allows individuals to grow and change by expanding the number of total cells

Cells, including single-celled organisms, use cell division to reproduce. Each time a parent cell divides, it results in 2 new organisms

Organisms have the ability to repair damage caused by the environment or by living processes. All organisms reproduce to increase their population number

Mitosis

Reproduce/Repair

Interphase (It is broken down to 3 parts)

Life must be able to respond to stimuli or stress from their environment

Irritability

Living things either have the ability to move, or spread their reproductive cells

Organisms have the ability to adapt to different environments or changes to their environment

Living things are able to use their environment to obtain nutrients essential for life

Living things grow larger and grow in numbers (includes some reproduction)

Metabolism

Adapt

Move (Motility)

Cell Types

To stay alive, all cells must do the same things: consume energy, store materials, take materials from the environment, eliminate wase, transfer chemicals to where they are required and reproduce. Within a cell, each organelle has a distinct purpose

A Eukaryotic cell also has specialised parts, called organelles, that carry out specific functions necessary to life

Your body is made up of many specialised organs that carry out all the processes needed to live

Cell Structure

Cell is the basic unit of life

All cells come from pre-existing cells

All living things are made up of 1 or more cells

Circulatory Disease

Blood

Arteries

Veins

Capillaries

The right ventricle pumps the oxygen-poor blood to the lungs through the pulmonary valve. The left ventricle pumps the oxygen-rich blood through the aortic valve out to the rest of the body

The tricuspid valve is one of the two main valves on the right side of your heart

The atrioventricular valves are those that connect the atrium to the ventricles and include the mitral valve as well as the tricuspid valve

The two atria are thin-walled chambers that receive blood from the veins.The right atrium receives deoxygenated blood from systemic veins; the left atrium receives oxygenated blood from the pulmonary veins

It is the valve between the heart and the body. The aortic valve opens when the left ventricle squeezes to pump out blood, and closes in between heart beats to keep blood from going backward into the heart

The pulmonary veins are the veins that transfer oxygenated blood from the lungs to the heart

The pulmonary arteries carry blood from the right side of the heart to the lungs

The aorta is the main artery that carries blood away from your heart to the rest of your body

The inferior vena cava carries blood from the legs, feet, and organs in the abdomen and pelvis

The superior vena cava carries blood from the head, neck, arms, and chest

The gallbladder is a sac located under the liver

The liver is essential for digesting food and ridding your body of toxic substances

It is located inside your abdomen, just behind your stomach. It's about the size of your hand. During digestion, your pancreas makes pancreatic juices called enzymes.

The stomach is a muscular organ that digests food

The anus is the opening at the lower end of the intestines.

The last several inches of the large intestine closest to the anus

The long, tube-like organ that is connected to the small intestine at one end and the anus at the other

A long tube-like organ that connects the stomach and the large intestine

The mouth is an oval-shaped cavity inside the skull

Teeth are hard, resistant structures occurring on the jaws and in or around the mouth

Salivary glands make saliva

The large air passages that lead from the trachea (windpipe) to the lungs.

Either of two external openings of the nasal cavity in vertebrates that admit air to the lungs

The esophagus is a hollow, muscular tube that connects the throat to the stomach. It lies behind the trachea (windpipe) and in front of the spine.

The Bronchioles is a tiny branch of air tubes in the lungs. Oxygen is inhaled into the lungs and passes through the thin membranes of the Alveoli and into the bloodstream

The pharynx serves both Respiratory and Digestive systems by receiving air from the nasal cavity and air, food and water from the oral cavity

The Nasal Cavity filters and warms the air that goes through your nose

One of a pair of organs in the chest that supplies the body with oxygen, and removes carbon dioxide from the body

Capillaries are small, thin blood vessels that connect the arteries and the veins. Their thin walls allow oxygen, nutrients, carbon dioxide and waste products to pass to and from the tissue cells

The Alveoli is where the lungs and the blood exchange oxygen and carbon dioxide during the process of breathing in and out

The Bronchus carries air into your lungs, then into your Alveoli

The Trachea carries air in and out of your lungs

The Larynx protects the lower airways, facilitates respiration

The Epiglottis prevents food and drinks from entering your wind pipe

The Digestive System consists of a variety of parts working together in unison to perform the task of digesting. These parts are known as ORGANS and each system has it's own bunch of organs within it's system.

The Respiratory System consists of a variety of parts working together in unison to perform the task of breathing. These parts are known as ORGANS and each system has it's own bunch of organs within it's system.

Also called the cardiovascular system or the vascular system, is an organ system that permits blood to circulate and transport nutrients, oxygen, carbon dioxide, hormones, and blood cells to and from the cells in the body

Consisted of organs that work together to take in food and liquids and break them down into substances that the body can use for energy, growth, and tissue repair. Waste products the body cannot use leave the body through bowel movements.

The set of organs that allows a person to breathe and exchange oxygen and carbon dioxide throughout the body.
