Cell structure as seen using a light microscope Flashcards
What is the protoplasm of a cell made up of in an animal cell?
Made up of the nucleus and the surrounding cytoplasm
Where do many of the reactions in a cell take place?
In the cytoplasm
What are plant cells enclosed by?
They are enclosed by a rigid cell wall made of cellulose.
What is cellulose?
It is a strong structural carbohydrate (or polysaccharide) and is the main component of paper and cotton wool.
What does the cell wall give to the cell?
It gives the cell strength and makes it less flexible
Why can the cell membrane sometimes not be seen in a plant cell?
The cell wall and membrane are often so close that the membrane is not seen clearly.
What do vacuoles in a plant cell contain? What is this made of?
A fluid called cell sap. This is a solution of salts, sugars and pigments.
What do plant cells have that animal cells don’t or only have a small size/version of?
Vacuoles
What does the vacuole in a plant cell do for it?
The vacuole helps to give the cell strength and shape and may also store materials.
What do green plants contain?
Structures called chloroplasts. These are the structures in which photosynthesis takes place
Define protoplasm
The Protoplasm is all the living materials in a cell outside the nucleus
