Question 4

What do only plant cells contain?

Answer 4

-chloroplasts
-permanent vacuole
-cell wall

Question 5

What is the function of the nucleus?

Answer 5

-contains DNA coding for a particular protein needed to build new cells
-enclosed in a nuclear membrane

Question 6

What is the function of cytoplasm?

Answer 6

-liquid substance in which chemical reactions occur
-contains enzymes
-organelles are found in it

Question 7

What is an enzyme?

Answer 7

biological catalysts, i.e. proteins that speed up the rate of reaction

Question 8

What is the function of the cell membrane?

Answer 8

-controls what enters and leaves the cell

Question 9

Mitochondria

Answer 9

-where aerobic respiration reactions occur, providing energy for the the cell

Question 10

Ribosomes

Answer 10

-where protein synthesis occurs
-found on a structure called the rough endoplasmic reticulum

Question 11

What is the function of chloroplasts?

Answer 11

-where photosynthesis takes place, providing food for the plant
-contains chlorophyll pigment (which makes it green) which harvests the light needed for photosynthesis

Question 12

What is the function of permanent vacuole?

Answer 12

-contains cell sap
-found in the cytoplasm
-provides strength to the cell

Question 13

What organelles are in bacteria (prokaryotic) cells?

Answer 13

-cytoplasm
-cell membrane
-cell wall
-single circular strand of DNA
-plasmids

Question 14

What is the function of the cell wall?

Answer 14

• provides the cell with structural support, shape, protection, and functions as a selective barrier
  -made of a different compound (peptidoglycan)

Question 15

What are plasmids?

Answer 15

Small rings of DNA
