A. Title

ANALYSIS OF DIFFERENCES IN THE STRUCTURE OF ANIMAL CELLS AND PLANT CELLS

B. Tujuan Prakritikum

  At the end of this practicum, it is expected that the practicum participants will be able to explain in detail the structure of animal cells and plant cells, and the practicum participants will be able to describe the parts of animal cells and plant cells, and be able to explain the differences between animal cells and plant cells based on the results of observations obtained from the practicum.

Cheek Mucosa Preparation

E. Observation Results

NO	SAMPLE NAME	DOCUMENTATION	DESCRIPTION
1	Garlic Onion		After observing Allium cepa cells taken from a thin membrane on a red onion using a microscope with a magnification of 40x10, several parts of the cell can be seen, including the cell wall, nucleus and cytoplasm.
2	Cheek Mucosa		The structure of the cheek epithelial cells includes cell shape, cell nucleus, and cell membrane in the cheek mucosa. Cheek mucosa cells are usually not tightly arranged like other epithelial tissues. This is because sampling is done randomly. And the cell structure begins to be seen at a magnification of 100x10.

F. Discussion Results

Activity

• Red onion ( Allium Cepa )

 First of all, prepare the tools and materials to be used, then start slicing the onion skin thinly using a caterer to take the inner membrane of the red onion, then place it on a glass object and drip it using lugol's solution, then cover it with a cover glass then observe using a microscope with a magnification of 10x10 we have not gotten good results so we increase the magnification and 10x40. We did several samplings to get good results. Then observe and draw to write the results of allium cepa on the microscope, it can be seen that the red onion cells contain cell organelles such as cytoplasm, cell walls and nucleus, as explained by Nissafrieda (2018)

• Cheek Mucosa

prepare tools and materials. Then take the inner cheek mucosa using a toothpick to make it easier, we do this step slowly so as not to cause injury to the inside of the cheek, then place it on a glass object glass to be observed. Dropped with Aquadest liquid so that it is clearly visible when observed using a microscope. Based on the results of observations, the part that is very clearly visible is the cell nucleus. Then cover the sample using a cover glass so that it does not move when observed with a microscope with an initial magnification of 10 x10 but we have not been able to see the cells that must be observed so we try to increase the magnification of the microscope lens to a magnification of 100x10. Then it started to look so we observed and drew to write down the results. As explained by S Ristawati (2019)
