Question

Which cell organelles release oxygen?
A. Mitochondria
B. Golgi body
C. Chloroplast
D. Ribosome

Answer 1

Hint:- Photosynthesis is the process by which green plants transform light energy into chemical energy. During photosynthesis, the light energy is captured and used to convert water, carbon dioxide and minerals into oxygen and energy-rich organic compounds like glucose.

Complete Answer:- Chloroplasts are plant cell organelles that conduct photosynthesis. The chloroplasts are green plastids which carry out the process of photosynthesis and the pigment chlorophyll captures the energy from sunlight and then converts it, and stores it in the energy-storage molecules ATP and NADPH while freeing oxygen from water in photosynthesizing cells. Oxygen is released in chloroplasts as a result of photolysis of water and is a byproduct of photosynthesis.
The chloroplast is located in the plant cell. It helps to carry out the process of photosynthesis and result in the release of oxygen during the photolysis of water. The Golgi apparatus or Golgi body is an organelle found in most eukaryotic cells as a part of the endomembrane system in the cytoplasm. It packages proteins into membrane-bound vesicles after which the vesicles are sent to their destination. Thus these are required for transporting, modifying and packaging proteins and lipids.
Mitochondria is a double membrane-bound cell organelles found in most eukaryotic organisms. It generates the chemical energy needed to power the biochemical reactions of the cell. Chemical energy produced is then stored in the form of adenosine triphosphate (ATP). Ribosomes are minute particles floating within the cytoplasm or attached to the endoplasmic reticulum consisting of RNA and associated proteins that function to synthesize proteins. The amino acids are linked together in the form of codons of messenger RNA molecules to form polypeptide polymer chains.

So, the correct option is (C) Chloroplast.

Note:- Unicellular organisms including microsporidia and diplomonads are known to have reduced or transformed their mitochondria into other structures. While Some cells in some multicellular organisms even lack cell organelles like mitochondria.
