Question

The main difference between human cheek cell and onion peel is
a) Presence of cell wall in onion peel cells.
b) Presence of mitochondria in onion peel cells.
c) Absence of Endoplasmic reticulum in cheek cell.
d) Absence of plasma - membrane in cheek cell.​

Answer 1

❇ The correct answer is Option A

$\large{ \rm{ \underline{ \red{Presence \: of \: cell \: wall \: in \: onion \: peel \: cells}}}}$

❇ Explanation:

✏Cell wall:

The cell wall is a rigid, non living and outer most protective covering of the cells which lies outside the plasma membrane of plants cells, fungal cells, and some prokaryotic cells like bacteria. It is absent in animal cells. It helps in the rigidity and support to the cells.

In Onion peel cell

The onion peel cells is a plant cell, and after observing and analysing the result of experiment, we will see similar, elongated and rectangular cells joined together. Each cell consists of an Cell wall. They also have dense cytoplasm with a covering of plasma membrane and nucleus at periphery.

In human cheek cell

They are animal cells, and after observing the results of experiment, we will see large number of flat, irregular cells with dark stained nucleus in the centre of the cell. They don't have Cell wall. Other organelles like ER, mitocondria, plasma membrane are found in both kind of cells.
