Question

biochemistry online practice complete this assessment to review what youve learned. it will not count toward your grade. which statement is true? (1 point) animals perform cellular respiration and photosynthesis, but plants only perform photosynthesis. plants perform cellular respiration and photosynthesis, but animals only perform cellular respiration. animals only perform cellular respiration, and plants only perform photosynthesis. plants and animals perform cellular respiration and photosynthesis.

Explanation:

• Analyze each option:
• Option 1: Animals lack chloroplasts, so they can't do photosynthesis. Plants do cellular respiration (to use energy from glucose) and photosynthesis (to make glucose). So this is wrong.
• Option 2: Plants have chloroplasts for photosynthesis and mitochondria for cellular respiration. Animals have mitochondria for cellular respiration but no chloroplasts for photosynthesis. This matches the biological processes.
• Option 3: Plants do cellular respiration (to break down glucose made in photosynthesis for energy), so saying plants only do photosynthesis is wrong.
• Option 4: Animals can't do photosynthesis (no chloroplasts), so this is wrong.

Answer:

B. Plants perform cellular respiration and photosynthesis, but animals only perform cellular respiration.
