Difficulty: EasyCell Structure and Function

Which organelle is found in plant cells and functions as the primary site of photosynthesis?

  1. A
    Ribosome
  2. ChloroplastAnswer
  3. C
    Mitochondrion
  4. D
    Endoplasmic reticulum

Answer

Chloroplast
Chloroplasts are double-membrane organelles found in plants and algae that contain the green pigment chlorophyll. They absorb solar energy to convert carbon dioxide and water into glucose through the process of photosynthesis.

Step-by-Step Solution

1
Identify the cellular process and target cell type in the question
The question asks for the organelle responsible for photosynthesis in plant cells.
Pinpointing the specific biochemical process helps narrow down the organelle's specialized function.
2
Match the organelle to photosynthesis
Chloroplasts contain chlorophyll pigments that absorb sunlight to synthesize glucose from water and carbon dioxide.
Chloroplasts are uniquely adapted for photosynthesis and are characteristic of plant cells rather than animal cells.
