What organelle allows for photosynthesis to occur?
A
mitochondria
B
chlorophyll
C
chloroplast
D
lysosome
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, the organelles responsible for photosynthesis, are in many respects similar to mitochondria. Both chloroplasts and mitochondria function to generate metabolic energy, evolved by endosymbiosis, contain their own genetic systems, and replicate by division.

Detailed explanation-3: -The chloroplast contains a green pigment called chlorophyll which is very essential for photosynthesis. The cell organelle in which photosynthesis takes place is plastids. Plastids are double membrane-bound organelle that has their DNA and acts as a semi-autonomous organelle.

Detailed explanation-4: -Chloroplasts produce energy through photosynthesis and oxygen-release processes, which sustain plant growth and crop yield. As such, chloroplasts are responsible for the biosynthesis of active compounds such as amino acids, phytohormones, nucleotides, vitamins, lipids, and secondary metabolites [9].

Detailed explanation-5: -The purpose of the chloroplast is to make sugars that feed the cell’s machinery. Photosynthesis is the process of a plant taking energy from the Sun and creating sugars. When the energy from the Sun hits a chloroplast and the chlorophyll molecules, light energy is converted into the chemical energy.
