Question 1
Chloroplasts carry out photosynthesis in the plant cell described. Which structure uses light in that process?
- Storage vacuole
- Chloroplast
- Cell wall
- Nucleus
A hint
Match the function stated in the question to the described structure.
Answer & why
Answer: Chloroplast
The stated photosynthesis structure is the chloroplast.
Question 2
Mitochondria help release usable energy from food during cellular respiration. Which structure fits that function?
- Chromosome name
- Surface label
- Cell-wall fiber
- Mitochondrion
A hint
Match the function stated in the question to the described structure.
Answer & why
Answer: Mitochondrion
The prompt identifies mitochondria with this energy-release process.
Question 3
This plant cell has a large vacuole storing water and dissolved substances. Which function is described?
- Removing every membrane
- Producing the cell's outer label
- Turning DNA into a wall
- Storage
A hint
Match the function stated in the question to the described structure.
Answer & why
Answer: Storage
Holding water and dissolved substances is a storage function.
Question 4
A diagram shows a plant cell with chloroplasts. Which conclusion would go beyond that one diagram?
- The diagram represents one cell model.
- The drawn cell includes chloroplasts.
- The drawing labels a cell structure.
- All living cells have chloroplasts.
A hint
Match the function stated in the question to the described structure.
Answer & why
Answer: All living cells have chloroplasts.
A model of one plant cell cannot establish that every cell has the same structures.
Question 5
A cell membrane controls movement of substances into and out of a cell. Which structure regulates this exchange?
- Cell membrane
- Starch grain
- Cell wall only
- Chromosome label
A hint
Match the function stated in the question to the described structure.
Answer & why
Answer: Cell membrane
The supplied description assigns exchange control to the cell membrane.
Question 6
In this eukaryotic cell, the nucleus contains most of the DNA. Which structure stores most of its genetic information?
- Nucleus
- Food vacuole only
- Cell-wall drawing
- Outer label
A hint
Match the function stated in the question to the described structure.
Answer & why
Answer: Nucleus
The prompt locates most DNA in this cell's nucleus.
