The plant organelle that captures light to make energy is the:
A
Cell Wall
B
Mitochondria
C
Chloroplast
D
Ribosome
Explanation: 

Detailed explanation-1: -In plants and algae, which developed much later, photosynthesis occurs in a specialized intracellular organelle-the chloroplast. Chloroplasts perform photosynthesis during the daylight hours. The immediate products of photosynthesis, NADPH and ATP, are used by the photosynthetic cells to produce many organic molecules.

Detailed explanation-2: -Chloroplasts are organelles found in the broccoli’s cells, along with those of other plants and algae. They capture light energy and store it as fuel molecules in the plant’s tissues.

Detailed explanation-3: -In particular, organelles called chloroplasts allow plants to capture the energy of the Sun in energy-rich molecules; cell walls allow plants to have rigid structures as varied as wood trunks and supple leaves; and vacuoles allow plant cells to change size.

Detailed explanation-4: -In plants, the so-called “light” reactions occur within the chloroplast thylakoids, where the aforementioned chlorophyll pigments reside. When light energy reaches the pigment molecules, it energizes the electrons within them, and these electrons are shunted to an electron transport chain in the thylakoid membrane.

Detailed explanation-5: -A chloroplast is a green organelle which some eukaryotes, such as plants and algae, have in their cells. It is in charge of photosynthesis, the process which produces the energy which the organism needs to survive. A chloroplast uses energy from light to make sugars from carbon dioxide (CO2) and water (H2O).
