Some components of cells are listed.

Question

Cytoplasm
Nucleus
Chloroplasts
Cell Wall
Cell membrane
Which of the components could be observed using a microscope in a prepared slide of leaf epidermal cells but not in a prepared slide of human cheek cells?

a
Components 3 and 4 only
b
Components 1, 2, and 3 only
c
Components 2 and 3 only
d
Components 1 and 5 only

Answer 1

To determine which components can be observed in a prepared slide of leaf epidermal cells but not in a prepared slide of human cheek cells, let's analyze each component:

1. Cytoplasm - Present in both leaf epidermal cells and human cheek cells.
2. Nucleus - Present in both leaf epidermal cells and human cheek cells.
3. Chloroplasts - Present in leaf epidermal cells (specifically in mesophyll cells) but not in human cheek cells.
4. Cell Wall - Present in plant cells (like leaf epidermal cells) but not in human cheek cells (animal cells).
5. Cell Membrane - Present in both leaf epidermal cells and human cheek cells.

From this analysis, the components that can be observed in leaf epidermal cells but not in human cheek cells are Chloroplasts (3) and Cell Wall (4).

Therefore, the correct answer is a. Components 3 and 4 only.
