Question

(02.03 lc)
which of the following correctly compares how plant and animal cells differ?

○ a plant cells have chloroplasts and mitochondria for energy, but animal cells do not have mitochondria.
○ b plant cells have a cell membrane and cell walls for support, but animal cells do not have cell walls.
○ c plant cells have ribosomes for synthesis, while animal cells have the golgi apparatus.
○ d plant cells have many small vacuoles for storage, while animal cells have one large central vacuole.

question 2 (4 points)
(02.03 lc)
which organelle is the powerhouse of the cell and produces energy?

○ a golgi apparatus
○ b nucleus
○ c mitochondria
○ d ribosome

Explanation:

Question 1

• Option a: Animal cells do have mitochondria (they use it for energy), so a is wrong.
• Option b: Plant cells have a cell membrane (like animal cells) and a cell wall for support; animal cells lack cell walls. This is correct.
• Option c: Both plant and animal cells have ribosomes and Golgi apparatus, so c is wrong.
• Option d: Plant cells have one large central vacuole, animal cells have many small vacuoles (or none), so d is wrong.

• The mitochondria are known as the "powerhouse of the cell" because they produce ATP (energy) through cellular respiration.
• Golgi apparatus modifies and packages proteins, nucleus is the control center, ribosomes make proteins. So the correct organelle is mitochondria.

Answer:

b. Plant cells have a cell membrane and cell walls for support, but animal cells do not have cell walls.
