Flowers,reproduction,methods of reproduction and methods of dispersing seeds
Time for reproduction
Method 2 of pollination is self-pollination it is the opposite of cross-pollination so one individual butterfly or bee lands on one flowers anther to collect nectar but this time is does not leave but flies on to the stigma to get nectar thus causing self-pollination
There are two ways of pollen grains arriving at the other flowers from stigma to anther
Method 2 of pollination insect-pollination which can only happen if the flower has flashy-colors,sweet tasting nectar and it must be sweet-smelling then the bee or butterfly gets attracted to it and lands on the anther and after its got its share of nectar from this plant it will go to another flower and land on the stigma dropping pollen grains on the stigma causing pollination
Method one is air pollination which could only happen if the flower has a hairy stigma sticking out of the plant to catch the pollen grains mid-air
Method 1 of pollination is cross-pollination when a bee or a butterfly lands on an anther of a flower to get nectar but does not land on the stigma after it lands on the anther thus pollination on that flower does not happen but on another flower pollination as the bee or butterfly the same one that landed on the one individual flower landed on another flower but now on the stigma thus as a result pollination happens
parts of a female flower
unlike the male flower it has more then one plant part,filament(the tube under the stigma),stigma(platform for collecting pollengrains),ovary,ovules and i think thats all
Fun fact: did you know that the stigma has a sticky platform so that the pollen grains that have landed on it wont be blown away by the wind
Parts of a male flower
the parts of a male flower is simple only one so the anther is covered with pollen grains also known as the male cell of a flower
an example of a male papaya flower
plant defence
some plants defend themselves by sometimes having a bitter taste and some like chilli have capsaicin gives the taster a hot feeling in his mouth or have spikes over it like a durian and lastly have poison in it mandrake
Blooming time
the petals start to separate after the stigma and anther are fully developed under the petals
The methods of dispersal
Seed dispersal is how are seeds dispersed and its important because without seed dispersal over-crowding will take place
the first method of seed dispersal is wind dispersal, this process happens when strong winds gather under the wing of a seed of a plant that is dispersed by wind
The second method of seed dispersal is water dispersal,this process of seed dispersal takes place if a plant is near water and its seed is covered with a water-proof husks that are filled with air and will float until it reaches land
The third method of seed dispersal is animal dispersal by either the seeds get tangled into the animals fur or the fruit gets eaten and the seed spit out,some animals eat both the fruit and seed
The fourth method of seed dispersal is is explosive action which is by splitting open and is also known as self dispersal
Fruits
Fruits are actually the ovary swelling up whilst the ovules turn into the seeds of the fruit which all happen after the pollen grains reach the female egg cell and that happens after fertilisation
Start of a flower
the start of a flower is germination when the seed has aquired warmth and damp surroundings that is when it will germinate
Flower gender
You think flowers dont have genders but your wrong some flowers have both male and female body parts and a type of flower that has either male and female body parts
These flowers only have either have male or female body parts so they only have separate genders
These flowers have both female and male body parts so they have both genders
Poisonous plants
Some plants are not all poison only some parts like the tomato leaves or sometimes we eat plants that are all poison but since we boil it the germs will die
Some plants are poisonous to eat like mandrake or henbane and dont want to be eaten most poisonous plants are flowering but there method of dispersing is different.
importance of dispersing
dispersing prevents overcrowding and competition for sunlight, thats why you rarely see plants packed closely in the wild
it is important to disperse seeds because if a plant cant disperse seeds it cannot prevent overcrowding and the seeds would be tall and thin but if seeds are dispersed correctly the saplings that grow from the correctly dispersed seeds will grow to be short but have thick stems
What is a plant and what is not a plant
Some people often mistake mushrooms for plants but there not plants are well living things with leaves on them but mushrooms are fungi (fung-guy) which like ferns reproduce by spreading fungal spores.
Ferns
Ferns are unlike the flower are non-flowering plants that instead of seeds they produce spores which are on top of the spore bags that are located under the leaves
Ferns dont have the same reproductive cycle as a flowering plant you know why, because ferns dont have the same reproductive system as a flowering plant
The habitat of a carnivorous plant
carnivorous plants like cold nutritionless
carnivorous plants dont like soil with nutrition because they dont need it and it attracts flowering plants to crowd the space needed to attract unsuspecting prey and the nutritional soil will crowd it with flowering plants and instead of small mammals it will be bees
Carnivorous plants
carnivorous plants are different to flowering and non-flowering plants, carnivorous plants eat small rodents insects and anything that it could fit into is mouth, some example of carnivorous plants are the pitcher plant which lures prey by releasing a purfume like stench luring unsuspecting insects into it wide gaping mouth and closing i lid trapping the insects inside while digesting them alive, and the famous venus flytrap which strangely is not from venus, its actually from earth, and lures play the same way like a pitcher plants and eats fly (like its name the venus FLYtrap) and smaller insects
Trees
unlike flowers, trees take a long time to grow probably a hundred years and a tree unlike a flower has a longer life span
trees are also plants that are large but also keep fruits because flowers are located on the leaves or branches of that one individual tree,their are also non-fruit bearing trees like the five-dollar tree of singapore which are sometimes result to the trees heriditary characteristics
a little seedling appears after germination with newly developed seed leaves while its new leaves grow so while the main leaves are growing the seed leaves provide nutrition for the seedling to grow
Petals
After the leaves are fully developed petals start to appear but not spread out but packed closely together
