JOURNAL 5: DIVISION CYCLE OF PLANTS AND TOTIPOTENCY

Week 5
Division cycle also occur in plant since they need to grow in cell number.

--> mitosis


What is mean by totipotency??

Before the lecture session start, I do not know the concept of totipotency. But after I do the researching, totipotency is an ability of plant to regenerate into a whole plant even by plant cell/tissue/organ.

It means plant is an indeterminate organism. Even you cut, it will grow as whole. Look on how unique plant is.

Furthermore, this ability have different pathways of regeneration by the plant and tissue culture process. This tissue culture will begin from the explant.



New terms that I learned:

Explant - transfer (living cells, tissues, or organs) from animals or plants to a nutrient medium.

Callus - a thickened and hardened part of the skin or soft tissue, especially in an area that has been subjected                   to friction.

 


What activity we done during the lesson??

Cell division concept map- fill in the blanks with words given

Lesson that I get     - get to know the principle of cell division and have better understanding
                                - learn in most simple ways by using mind map
                                - work in group much easier and faster
                                - discuss word that hard to understand

Plant is a complicated structures, but if you try hard to understand the learning, the difficulties you may face will become easier for you.

REFLECTIVE LEARNING

A journey of growing plant. By: Adila Erwin Date: 25 January 2021   This is my first time experience to actually growing a plant. Through this journey, a lot of new information I have gained since I indulge in this plant project. What I have learned in theory class is different from the practical. This project have teach me such as the soil types, the used of rice husk, and the types of fertilizers used is depend on which stages we would like it to grow into. In addition, I also learnt some plants can be very sensitive but some can be very resistant.  This project also teach me to be more patience and find a way to solve it. During 10 or 11 weeks of growing, my plants have not yet undergo flowering stages. A single bud is still not visible. To solve this problem, I have learnt things such as providing suitable fertilizer that encourage for the flowering stages to occur.       Along the journey, I have faced several obstacles which prevent my plant from growing healthily, in which the a

JOURNAL 6: POLLINATION AND DEVELOPMENT OF EMBRYO

Image
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 embryogenesi s (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 experienc
