In which organelle of the plant cells does photosynthesis take place?

Correct option is A

The correct answer is (a) Chloroplast

Explanation:

• Photosynthesis is the process by which plants convert sunlight into chemical energy in the form of glucose.
• This process occurs in the chloroplasts, which contain chlorophyll, the green pigment responsible for capturing sunlight.

Information Booster:

Chloroplast Structure:

Thylakoids: Contain chlorophyll, where light-dependent reactions occur.

Stroma: Site of the Calvin cycle (light-independent reactions).

Photosynthesis Equation:

                        $$6CO_2 + 6H_2O + Light \rightarrow C_6H_{12}O_6 + 6O_2$$​​

Importance of Photosynthesis:

• Produces oxygen as a byproduct.
• Converts solar energy into glucose, which serves as food for plants and other organisms.

Additional Knowledge:

Mitochondria are the powerhouses of the cell, responsible for cellular respiration.

Ribosome –

• Definition: Ribosomes are small, protein-synthesizing organelles found in both prokaryotic and eukaryotic cells.
• Structure: Composed of ribosomal RNA (rRNA) and proteins, consisting of two subunits (large and small).
• Location: Found freely in the cytoplasm or attached to the endoplasmic reticulum (Rough ER) in eukaryotic cells.
• Function: Responsible for protein synthesis by translating messenger RNA (mRNA) into amino acid chains.
• Types:
• 70S Ribosomes (found in prokaryotes, mitochondria, and chloroplasts).
• 80S Ribosomes (found in the cytoplasm of eukaryotic cells).
