Plant and Cell Biology Concepts

What is a characteristic of eukaryotic cells?

• Have a cell wall

• Lack a nucleus

• Have a membrane-bound nucleus

• Are always smaller than prokaryotic cells

What is the largest single animal cell?

• Human egg cell

• Blue whale cell

• Unfertilized ostrich egg

• Elephant skin cell

Which of the following is found in both plant and animal cells?

• Cell wall

• Chloroplast

• Mitochondria

• Large central vacuole

What is the primary function of the nucleus in a cell?

• Produce energy

• Store genetic information

• Control cell movement

• Synthesize proteins

What is the main role of mitochondria in a cell?

• Store water

• Perform photosynthesis

• Produce energy (ATP)

• Build proteins

What is the cell wall of a plant cell primarily composed of, and what is its function?

• Protein, for movement

• Cellulose, for stability and protection

• Lipid, for energy storage

• DNA, for genetic information

How do plants obtain their energy?

• By consuming other organisms

• By ingesting food

• By producing their own food through photosynthesis

• By breaking down proteins

Which organelle is responsible for photosynthesis in plant cells?

• Mitochondria

• Nucleus

• Vacuole

What percentage of a plant cell's volume can a vacuole occupy?

• Up to 10%

• Up to 50%

• Up to 75%

• Up to 90%

Which of the following structures are typically found in animal cells but only in lower plant forms?

• Cell membrane

• Ribosomes
