Question:

Chloroplasts are present in the cells of which of the following organisms?
A. Fungi
B. Algae
C. Plants
D. Animals

Show Hint

Chloroplasts = Photosynthesis.
Only autotrophic eukaryotic groups (Plants and Algae) contain these organelles.
Fungi and Animals are heterotrophs and do not have them.
  • A and C only
  • C only
  • B and C only
  • C and D only

The Correct Option is C

Solution and Explanation

Step 1: Understanding the Concept:
Chloroplasts are specialized, double-membrane organelles responsible for photosynthesis in eukaryotic organisms.
They contain chlorophyll pigments that capture light energy to synthesize organic compounds from carbon dioxide and water.
Detailed Explanation:
Let us analyze each group:
A. Fungi:
Fungi are heterotrophic eukaryotes.
They lack chlorophyll and chloroplasts and obtain nutrients via absorption.
Thus, chloroplasts are absent in Fungi.
B. Algae:
Eukaryotic algae (including green, red, and brown algae) are photosynthetic autotrophs.
They possess chloroplasts (or plastids) containing photosynthetic pigments.
Thus, chloroplasts are present in Algae.
C. Plants:
All green plants (Viridiplantae) contain chloroplasts in their green tissues (primarily leaves) to carry out carbon assimilation.
Thus, chloroplasts are present in Plants.
D. Animals:
Animals are multicellular, ingestive heterotrophs and lack chloroplasts entirely.

Step 2: Final Answer:

Chloroplasts are present in Algae (B) and Plants (C).
Therefore, the correct option is (C).
