Hello! Today we just submitted our first assignment, cartoon on natural selection. I think my group has done a great job because each of us was putting our full effort and contribution to this assignment. Dr. continued her lecture of cell division and what I feel interesting was totipotency. A plant cell, tissue or organ can be regenerated into a whole new plant under right condition. Wow! How amazing it could be!

 

And I think the part that most of us had difficulty to understand was callogenesis. However, Dr. was explaining slowly to us about the forms of plant changing throughout the process, from undifferentiated tissue to differentiated tissue. I was really paying full attention to this part so that I was not confused by dedifferentiation and redifferentiation.

In the next lesson, we learned about pollination and development of plant embryo. It was almost the same as what I learned in the past and I am quite familiar with the terms “pollination”, “double fertilization” and “embryogenesis”  but I have to take my time to recall all these processes and the reproductive organ of plants.

Things that was new to me was somatic embryogenesis. Dr. was explaining that part in detail to make sure we fully understood and not confused. Today, I am introduced to even more new terms such as differentiated  and undifferentatied cells, callus, direct and indirect organogenesis but all these terms can be easily absorbed and digested after the clear explanation by Dr. Parames. We drew the venn diagram to illustrate the similarities and differences between zygotic and somatic embryogenesis as usual.
