Which plant cell organelle converts chemical fuel into packets of chemical energy that can power the cell?
A. Mitochondrion.
B. Chloroplast.
C. Central vacuole.
D. Golgi apparatus.
E. Plasma membrane.
answer
Answer: A. Mitochondrion.
In both plant and animal cells, it's the mitochondria that convert chemical fuel into packets of chemical energy that can power the cell.
question
The plant cell wall
A. is found just inside the plasma membrane.
B. is a protective structure made of cellulose fibrils.
C. regulates the composition of the cytoplasm.
D. makes food by converting light energy to chemical energy.
E. is very similar to the animal cell wall.
answer
Answer: B. is a protective structure made of cellulose fibrils.
The cell wall is a structure that protects the plant cell and is made of cellulose fibrils.
question
Which of the following is a function of the central vacuole?
A. Storing the genetic information of the cell
B. Converting light energy to chemical energy
C. Separating the cell from its surroundings
D. Storing compounds produced by the cell
E. Working with mRNA to synthesize proteins
answer
Answer: D. Storing compounds produced by the cell
One of the functions of the central vacuole is to store compounds produced by the cell.
question

A. Plasma membranes; mitochondria
B. Central vacuoles; ribosomes
C. Chloroplasts; central vacuoles
D. Cell walls; chloroplasts
E. Lysosomes; plasma membranes
answer
Answer: B. Central vacuoles; ribosomes
Central vacuoles are found only in plant cells. Ribosomes are found in both plant and animal cells.
