PLANT CELLS:
Have regular shape
Have cell wall, chloroplasts (most of the cells, but not all), a big vacuole
A. Cell Wall:
Made of cellulose
Only in plant cells
Helps to support and protect the cell
Fully permeable (even very large molecules are able to go through the cellulose cell wall)
B. Vacuole:
It is a space in a cell surrounded by a membrane and contain a solution of sugars and other substances called “cell sap”
Full vacuoles press outwards on the rest of the cell and help to keep it in shape
(animal cells contain much smaller vacuoles)
C. Chloroplasts:
Never found in animal cells
Present in Most of the plant cells
Contain “Chlorophyll” (absorbs energy from sunlight, and this energy is then used for making food for the plant by “Photosynthesis”
Often contain starch grains which have been made by Photosynthesis
