What is cytoplasm?

Answer 8

Gel like substance where most of the chemical reactions happen.

Contains enzymes that control the chemical reactions.

Question 9

Why does a cell have a partially permeable cell membrane?

Answer 9

Holds the cell together and controls what goes in and out

Question 10

What is mitochondria?

Answer 10

Contains enzymes need to control most of the reactions in aerobic respiration

Answer 28

One long circular chromosome, which floats free in the cytoplasm Plasmids

Question 29

What are plasmids?

Answer 29

Small loops of extra DNA, containing genes for drug resistance and can be passed between prokaryotic cells. NOT ALL PROKARYOTIC CELLS CONTAIN PLASMIDS
