Plant cells contain both chloroplasts and mitochondria; animal cells have only mitochondria. What can be inferred from this stat
ement? A. Plant cells do not use ATP
B Animal cells make their energy with chloroplasts.
C Chloroplasts make glucose; mitochondira break glucose down into ATP.
D. Plants do not eat, so both chloroplasts and mitochondria are needed to make enough energy for plants to grow.
Answer: D. Plants do not eat, so both chloroplasts and mitochondria are needed to make enough energy for plants to grow.
Explanation: Option A is invalid since plant cells do use ATP. Option B is invalid since animal cells don't make their energy with chloroplasts. Option D is the most realistic one since chloroplasts in the plant are the ones that make the food for the plants, plant doesn't have a "mouth" so they depend on chloroplast to make food.
Organisms need carbon for building cells and energy to fuel the process; eukaryotes, in general, all follow the same basic metabolic pathways whereas prokaryotes use a variety of materials and pathways—some employed by no other organisms.
