Study Notes

Cell Wall

Found only in plant cells
Plant cell swells up but cannot burst due to cell wall
It is made of cellulose, which is a non-living material
It is freely permeable
It is rigid, so it helps the cell keep its shape

Chloroplast

Not present in fungi or animal cells; only present in plant cells
Contains chlorophyll
Chlorophyll is a green pigment; it absorbs light energy to make food in the process of photosynthesis

Vacuole

Found only in plant cells
Filled with cell sap
Cell sap is a store of dissolved sugars, minerals, ions and other solutes(sodium chlorine)
Helps keep the cells shape

Ribosomes

Protein synthesis take place (produces proteins)
Found in all kind of cells
Extremely microscopic

Endoplasmic reticulum

Rough(presence of ribosomes)
Smooth(absence of ribosomes)

Description

This quiz explores essential components of plant cells, including the cell wall, chloroplasts, vacuoles, ribosomes, and the endoplasmic reticulum. Understand how each part contributes to the overall functioning and shape of plant cells. Test your knowledge on the unique features that distinguish plant cells from other types.
