Topic 4 - Eukaryotic Cell

Bismillahirrahmanirrahim
Assalamualaikum warahmatullahi wabarakatuh

Today, we learn on eukaryotic cell. For me, today’s lecture is the happiest studying time because we study while playing games. I gain a lot of knowledge and able to have fun at the same time. We play the games based on the topic given. The games that we play are Kahoot!, crossword, bingo,  flip card, musical chair and racing with organelles. My group has conducted the bingo game based on our topic under eukaryotic cell which is “Mitosis and Meiosis”. 

In microbial world, the eukaryotes are like protozoa, algae and fungi. Basically, eukaryotic cell has cilia and flagella, cytoplasm and organelles. What differentiates between eukaryotic cell with prokaryotic cell is, eukaryotic cell has membrane bound organelles like lysosome, vacuoles and chloroplast while prokaryotic cell is lacking in membrane bound organelles.

Eukaryotic flagella consist of 9 pairs of microtubules arranged in a ring plus two microtubules in the center (9+2 array). These flagella anchored to plasma membrane by a basal body and its movement is wavelike motion. Do not think that only prokaryotic cell can have cell wall, eukaryotic cell also have! But the cell wall in eukaryotes is much simpler such as fungi cell wall consists of chitin. Eukaryotes also contain sterols in the plasma membrane and with this cytoplasmic membrane they can do endocytosis, phagocytosis and pinocytosis.
The most special about eukaryotic cell is they undergo mitosis and meiosis which prokaryotic cells can never do that. Mitosis is to produce two daughter cells that are identical to the parent cell. This process is involved in growth and repair damaged tissue. On the other hand, meiosis is to produce daughter cells that have half the number of chromosomes as the parent cell. The significance of meiosis is to produce gametes (sperm and egg). In plants, gametes are not formed directly. Instead, meiosis produce spores and the mitosis produces gametes.


As an overall conclusion, now I am really really into Microbiology. I just love to gain knowledge about the microbes and always hope to encounter with more new things. With the end of eukaryotic cell topic, then it is also our last class with Dr. Wan. It has been 5 weeks already we learn Microbiology from her. Maybe 5 weeks is a short period but what she taught me along this time make me feel it like a life-long learning. I will retain the knowledge that she has gave because knowledge is more valuable than gold. Thank you Dr. Wan.



With love, Izzah.
