Question

Both plant and animal cells have mitochondria; however, only plant cells have chlorophyll contained in chloroplasts. Explain how this fact impacts photosynthesis and cellular respiration. Additionally, explain why only plant cells have cell walls and animal cells do not.

a) Plant cells use chlorophyll for photosynthesis, generating energy, while animal cells rely solely on mitochondria for energy production. Plant cells have cell walls to provide structural support, whereas animal cells have a flexible membrane for mobility.
b) Chlorophyll in plant cells enables photosynthesis, producing oxygen and glucose, vital for energy. Mitochondria in both cells facilitate cellular respiration. Plant cells have cell walls for protection, while animal cells rely on their internal structure for support.
c) Chlorophyll in plant cells captures sunlight for photosynthesis, generating energy and oxygen. Mitochondria in both cells aid cellular respiration. Plant cells have rigid cell walls for structure, whereas animal cells have a dynamic membrane allowing flexibility.
d) Plant cells utilize chlorophyll for photosynthesis, producing glucose and oxygen. Mitochondria in both cells support cellular respiration. Plant cells have cell walls providing rigidity, while animal cells lack cell walls, offering flexibility.

Answer 1

Plant cells have chloroplasts for photosynthesis and cell walls for structure, while animal cells rely on mitochondria for energy production and have a flexible membrane for mobility.

Step-by-step explanation:

Detailed Answer:

Plant cells have chloroplasts that contain chlorophyll, which is essential for photosynthesis. During photosynthesis, chlorophyll captures sunlight energy and converts it into glucose and oxygen. Animal cells, on the other hand, do not have chloroplasts and rely solely on mitochondria for energy production through cellular respiration.

Both plant and animal cells have mitochondria, which play a role in cellular respiration. Mitochondria convert glucose and oxygen into ATP, the main energy currency of the cell. This process occurs in both plant and animal cells.

Plant cells have cell walls made of cellulose, which provide structural support and protection for the cell. Cell walls also allow plants to maintain their shape. Animal cells, however, do not have cell walls and rely on their internal structure, including the cytoskeleton, for support and shape.
