Which of the following option(s) of the pairs of cell organelles are correctly placed under the given categories?
Explanation
Option (i) is the correct pair. Leucoplasts are a type of plastid, which are present in plant cells. The cell wall provides structural rigidity to plant cells and is absent in animal cells. Option (ii) is incorrect because ribosomes are present in animal cells. Option (iii) is incorrect because the Golgi complex/apparatus is present in animal cells. Option (iv) is incorrect because the endoplasmic reticulum is present in animal cells.
Solution Steps
Step 1: Analyze option (i) - Leucoplasts are plastids present in plant cells, and the cell wall provides rigidity to plant cells and is absent in animal cells. Thus, (i) is correctly placed.
Step 2: Analyze option (ii) - Mitochondria are present in plant cells, but ribosomes are also present in animal cells (implied by the presence of rough ER). Thus, (ii) is incorrectly placed.
Step 3: Analyze option (iii) - The cell wall is present in plant cells, but the Golgi complex is present in animal cells (as indicated in the provided table). Thus, (iii) is incorrectly placed.
Step 4: Analyze option (iv) - Lysosomes are present in cells, but the endoplasmic reticulum is present in animal cells too. Thus, (iv) is incorrectly placed.
