Question 1

What is in both plant and animal cells and there function

Answer 1

Nucleus-Controls all activity of cell. contains DNA coding for particular protein needed to build new cells. Enclosed by nuclear membrane.
Cytoplasm-liquid substance in which chemical reactions occur. Contains enzymes. Organelles found in it
Cell membrane-controls what enters and leaves the cell
Mitochondria-where aerobic respiration reactions occur,providing energy for cell
Ribosomes-where protein synthesis occurs

Question 2

What is only in plant cells and function

Answer 2

Chloroplasts-where photosynthesis takes olace,providing the food for the plant. Contains chlorophyll pigment (makes it green) which harvests the light needed for photosynthesis.
Permanant vacuole-contains cell sap. Found within cytoplasm. Improves cell’s rigidity
Cell wall-made from cellulose. Provides strength to the cell

Question 3

In bacterial cell?

Answer 3

Cytoplasm
Cell membrane
Cell wall-made from peptidogyclan
Singular circular strand of DNA-have no nucleus,floats in cytoplasm
Plasmids-small rings of DNA
