JOURNAL 6: POLLINATION AND DEVELOPMENT OF EMBRYO

Week 6

So now I will talk about plant pollination.

Do you know how pollination occurs?? Which part of plants involve in pollination?? How can plant do the double fertilisation??

Pollination occurs by the agent carrier such as wind, insect or water. This agent will transfer pollen to the part of seed plant containing the ovules.

Male reproductive organ are anther and filament while female reproductive organ are stigma,style and ovary.

There will be 2 sperm, one of it will fertilizes the egg generating into zygote, another one will fertilizes a polar cell with 2 nuclei and generating into endosperm.

This is only a short and simple introduction to this chapter.

What happens to zygote after fertilization??

---> zygotic embryogenesis
---> somatic embryogenesis (not normally involve in development of embryo)





Group Work as usual

We need to compare and contrast between zygotic and somatic embryogenesis. Both process occur from different embryo but they experienced the same stages of seed development. From this work, I got to differentiate both of the process.
