Question

A biologist ground up some plant leaf cells and then centrifuged the mixture to fractionate the Organelles in one of the heavier fractions could produce ATP in the light, while organelles in the lighter fraction could produce ATP in the dark. The heavier and lighter fractions are most likely to contain, respectively peroxisomes and chloroplasts. mitochondria and peroxisomes. chloroplasts and peroxisomes. mitochondria and chloroplasts. chloroplasts and mitochondria.

Answer 1

The correct option is D. Chloroplasts and mitochondria

Step-by-step explanation:

Chloroplast and mitochondria are structures that provide the plant cells with the energy driving molecule i.e ATP. Chloroplast is the structure where the process of photosynthesis takes place. Photosynthesis is a process in which carbon dioxide and water molecules combine, in the presence of light, to form glucose and oxygen. ATP is generated through this process.

Mitochondria are known as the powerhouse of the cell. In the leaves, it will generate ATP through the electron transport chain.
