Which organelle in a plant cell captures radiant energy from the Sun?
A.
chloroplast
B.
mitochondrion
C.
ribosome
D.
nucleus
A. chloroplast
The correct answer is A. chloroplast.
The correct answer is A. chloroplast.
To determine the correct answer, we need to understand what each organelle mentioned does in a cell.
A. Chloroplast: This organelle is responsible for capturing radiant energy from the Sun and carrying out photosynthesis in plant cells.
B. Mitochondrion: Mitochondria are involved in cellular respiration, which generates energy for the cell. However, they do not capture radiant energy from the Sun.
C. Ribosome: Ribosomes are responsible for protein synthesis. They are not directly involved in capturing radiant energy.
D. Nucleus: The nucleus contains the genetic material of the cell and controls cell activities. It does not capture radiant energy from the Sun.
Therefore, the correct answer is A. chloroplast, as it is the organelle in a plant cell that captures radiant energy from the Sun.
