fifth step of flowering

5. Division of the Fertilized Egg (Zygote) Fertilization is completed.In the following morning, the fertilized egg begins cell division to develop into an embryo.An embryo is a baby of the plant, which is kept dormant in the seed until the right condition for germination comes.

fourth step of flowering

Fertilization The rice plant carries out double fertilization as many other higher plants do. Double Fertization Step 1: Fertilization of the EggStep 2: Fertilization of the Polar Nuclei in the Embryo Sac

third step of flowering

Penetration of PollenTube into the Ovule The pollen tube reaches the ovule.It happens within 15-60 minutes after the pollen tube starts growing.

Pistil/carpel

first step of plant fertilization

Pollination takes place immediately before the anthesis. Anthers elevate by elongating the stamen filaments, and untimately they go out the spikelet during anthesis. When anthers touch stigma, some pollen is left on the stigma. The stigma can receive pollen also during the flowering when the spikelet opens.

function of anther

The anther is where the pollen is produced, and each anther contains many grains of pollen that each have the male reproductive cells present in them. Each flower can have just a few stamens, or hundreds of them.

function of filament

The function of the filament is simply to hold up the anther, extending it up to an accessible part of the flower for pollinators reach, or for the wind to disperse the pollen.

How does a seed develop?

as an embryo, the seed soaks up water and begins to feed on the nutritive tissue surrounding it. as it absorbs more water, it grows and grows and develops into a plant. the male gametes contained in pollen come in contact with the female gametes (ovules) through a process called pollination. Many plants rely on pollinator animals such as bees or butterflies to transfer pollen from the anther of one flower to the stigma of another flower. Pollen has male gametes containing half the normal chromosomes for that plant. After pollination, these gametes move to the ovule, where they combine with female gametes, which also contain half the quota of chromosomes. This process is called fertilisation. After fertilisation, the combined cell grows into an embryo inside a seed. The embryo is a tiny plant that has root, stem and leaf parts ready to grow into a new plant when conditions are right.

second step of flowering

pollen germination, Within 2 to 3 minutes, the pollen left on stigma starts to germinate, to grow pollen tube toward the egg cell.Pollen tubes are the pathways for sperm to reach the egg.

Function of the carpel/pistil

the female reproductive part of a flower, Each carpel has a swollen sac-like base called the ovary, which contains female reproductive cells called ovules. The ovary extends upward in a long slender tube called the style and terminates into a flat sticky surface called the stigma. The sticky surface of the stigma helps to capture pollen grains.When a pollen grain falls on the stigma, the pollen germinates to produce a long tube called pollen tube through the style. The pollen tube eventually reaches the ovules and fertilizes them. Each fertilized ovule develops into a seed and the ovary develops into a fleshy outer covering that gradually becomes the fruit.

The biological/evolutionary trade-offs of various strategies of flowering plant reproduction

there is only one bug that pollinates the orchid. The pollen will then be only spread to the same species of plant. Some plants have to spend a lot of calories and energy to produce a lot of pollen to spread by air.

function of flower petals

to attract pollinators and also protect the inner reproductive structures of a flower.

function of whole stamen

to produce pollen and make it available for pollinators to allow reproduction. When a pollinator, such as a bee or a bird, touches the anther the pollen will stick to them, and then get transported to other flowers they visit. This is where the carpel comes in.
