🔹The Formation of Embryo Sac in an Ovule 🥚🌺

➤ Ovule is formed from an ovarian tissue. Each ovule contains one megaspore mother cell (2n). [2m]
➤ The embryo sac mother cell (2n) undergoes meiosis to form 4 haploid megaspore cell (n). [2m]
➤ Three megaspores degenerated and only one megaspore will continue to develop. [1m]
➤ The remaining megaspore undergoes mitosis three time to form a with eight nuclei. [2m]
➤ Three cell move to one end near to micropyle, forming two synergid cell and one egg cell. [1m]
3 cell = 2 synergid + 1 egg
➤ Three more cells move to another end to form three antipodal cell. [1m]
➤ One cell with two nuclei located at the center to form polar nuclei. [1m]
➤ The structure formed is known as embryo sac which is protected by integument. [1m]

*ೃ༄The Formation of Pollen Grains in an Anther 🌺🌾

➣Occurs in the anther
➣In the anther, there are four pollen sacs on each lobe
➣In each pollen sac, there are hundreds of pollen mother cell called microspore mother cell which are diploid (2n)
➣The microspore mother cell divides by meiosis to produce 4 haploid (n) microspore cells. They are known as tetrad.
➣Each microspore cell undergo mitosis to become pollen grains.
➣The nucleus in the pollen grain divides by mitosis and produce 2 nuclei, namely the generative nucleus and tube nucleus.

༊*·˚How does POLLINATION occur ?🐝🪰🌼🌬

⚡️Pollination occurs when the wall of anther is dry, and it shrinks and split
⚡️This causes pollen grain from pollen sac to release.
⚡️The pollen grain is transferred to stigma by pollinating agents such as insects, wind and animal.
⚡️The pollen grains stick to the glucose in the stigma.
⚡️The glucose molecules then stimulate the germination of pollen grains.
⚡️It will form a pollen tube.
⚡️The pollen tube grows down towards the ovule through the style.
⚡️The generative nucleus will move along the pollen tube towards the ovule and divide by mitosis to form 2 male gametes (n).
⚡️End of pollen tube secrete enzyme to digest the tissues of style.
⚡️Upon reaching embryo sac, pollen tube penetrate the ovule through micropyle.
⚡️Tube nucleus degenerate. Both male gamete enter the embryo sac.
