Mastery Check 1.1.1

This diagram represents an animal cell.

Which labeled organelle in this animal cell would be much larger in a plant cell?

• Organelle W

• Organelle X

• Organelle Y

• Organelle Z

Which cell organelle is correctly paired with its function?

• vacuole—protein synthesis

• mitochondrion—photosynthesis

• chloroplast—cellular respiration

• nucleus—directs cellular activities

Which organelle works with the cell wall to keep a plant cell rigid?

• the nucleus

• the chloroplast

• the mitochondrion

• the central vacuole

Which organelles are most helpful in distinguishing between plant and animal cells?

• nucleus and chloroplast

• chloroplast and cell wall

• cell membrane and nucleus

• cell membrane and cell wall

This is a diagram of a plant cell.

If the demand for enzymes suddenly increased within a cell, which would most likely increase in number to meet this demand?

• I

• II

• III

• IV

Why is it important that the inner membrane of the mitochondria be folded in both plant and animal cells?

• The folded membrane increases the structure strength of the mitochondria.

• The folded membrane increases the surface area for energy production.

• The folded membrane increases the area available to construct proteins.

• The folded membrane increases the area for ribosomes to attach to its surface.

Which structure contains DNA?

• vacuole

• nucleus

• ribosome

• cell membrane

Which organelle would be found in large quantities in muscle cells?

• centriole

• vacuole

• nucleus

• mitochondrion

Which maintains homeostasis for the cell by regulating the movement of substances into and out of the cell?

• ribosomes

• cytoplasm

• mitochondria

• cell membrane

Which best describes how the cell wall is able to provide shape, structure, and protection for plant cells?

• It is bound by a double membrane for extra support.

• It is a system of flat, stacked membrane sacs.

• It is extremely large and provides needed storage.

• It is made of a tough carbohydrate called cellulose.
