Eubacteria are unicellular, prokaryotic organisms that lack a true nucleus and membrane-bound organelles. They have a rigid cell wall made of peptidoglycan and reproduce asexually. Classified by their shape, cell wall structure, and metabolic processes, eubacteria are essential for nutrient recycling, plant growth, and health in humans and animals.

Yeast . Beer and wine . Bread Mushrooms . White button . Truffles
Examples of food made possibly by fungi
. For food . They decompose wood and organic matter . Penicillin and order medicines . They are responsible for plant life and land and high productivity.
Why should we care about fungi?
Fungi produce antibiotics for the same reason we need them: To fight off bacteria infection
Why do fungi make antibiotics?
. Half a mushroom can kill a woman . The stinkhorn has being recorded as elongating to a length of 20 cm in only 2-3 hours . Many fungi are parasitic.
Facts about fungi

Main topic

Eubacteria

Eubacteria are an incredible diverse and essential group of organisms. They play crucial roles in ecosystems by recycling nutrients, supporting plant growth, and maintaining health in humans and animals.
conclution
Eubacteria are model organism for scientific research. They are also central to the development of antibiotics.
Decomposere, pathogens, biotechnology, symbiotic relationships.
Roles of eubacteria in ecosystems
Eubacteria are classified based on their shape, cell wall structure and metabolic processes. Here are some common groups: Green Algae
Classification of Eubacteria
Eubacteria lack a true nucleus, Most eubacteria have a rigid cell wall made of peptidoglycan, a unique polymer that provides structural strength, They reproduce asexually.
characterristics
Eubacteria, are unicelluar, prokaryotic organisms. Thy lack a membrane bound nucleus and organelles, and they are the most abundant and diverse group of organisms on earth.
Definition

Protists

Decompose organic material, absorbing nutrients. They exhibit both single- celled and multicellular phases.
Fungus-like protists(slime molds):
Heterotrophic, moving and consuming other organisms for energy. Example include: . Amoeba: moves by extending false feet . Paramecium: Moves using hair like structure
Paramecium
Amoeba
Animal-like protists (protozoa)
Autotrophic, using photosynthesis to produce energy. Examples include: . Green algae ( e.g spirogyra): photosynthetic and considered ancestors of modern plants. . Diatoms: Single-celled algae with silica cell wells, contributing to marine ecosystem as primary producers.

Spirogyra
plant-like protists (Algea)
. Fungi like penicilin- producing molds have revolutionized medicine by providing antibiotics.
Interesting facts
It is a eukariyotic organism, meaning their cells contain a nucleus and organelles. usually unicellular, That is not a fungus, animal, or plant.
Protists meaning

Plantae

Non-Vascular plants, seedless vascular plants,Gymnosperms.
Classification of plantae
Eukarotic cells, multicellular, asextual and sexual reproduction
Characteristics of kingdom plantae
It consist of multicellular eukaryotic organisms that are primarily autotrophic, meaning they their own food through photosynthesis.

Protista

protists play crucial role in ecosystem as primary producers, forming the base of aquqtic food web.
Ecology importance of protist
Protozoa, Algae
Classification of protista
Eukaryotic cells, mostly unicellular, diverse modes of nutrition,asexual and sexual reproduction.
Key characteristics of kingdom protista
It is a diverse group of eukaryotic organism that mainly include unicellular forms, although some multicellular organisms are also classified within this kingdom.
Definition of protista

Animalia

The animal kingdom is incredibly vast and diverse, spanning from simple sponges to complex mammals like animals.
Conclution
Sexual Reproduction: Most animals reproduce sextually, involving the production of haploid gametes (eggs and sperm). Asextual Reproduction: Some animals, particularly invertebrate, can reproduce asextually.
Reproduction and life cycles in Animalia:
Herbivores: Feed on plant. Canivores: Feed on other animals. Example: Lions, sharks, eagles.
Mode of nutrition
fish Amphibians Reptiles Birds mammals.
Subtopic
Vertebrates:
porifera (sponges): simplest animal with no tissues or organs Cindaria: Have a simple body structure with radial symmetry
Invertebrate:
Invertebrate: Animals without a backbone Vertebrates: Animals with a backbone
Classification of animals
Animals are eukaryotes, multicellular, heterotrophs, unlike plant and fungi animal cells do not have cell wall. Most animal have the ability to move at some point in their life cycle.
