Question

Some components of cells are listed. 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 2 and 3 only b Components 3 and 4 only c Components 1, 2, and 3 only d Components 1 and 5 only

Answer 1

To answer this question, we need to identify which components are present in leaf epidermal cells (specifically containing chloroplasts and a cell wall) but not in human cheek cells.

1. Cytoplasm - Present in both types of cells.
2. Nucleus - Present in both types of cells.
3. Chloroplasts - Present only in leaf epidermal cells (not in human cheek cells).
4. Cell Wall - Present only in leaf epidermal cells (not in human cheek cells).
5. Cell Membrane - Present in both types of cells.

Based on this analysis, chloroplasts (component 3) and the cell wall (component 4) can be observed in leaf cells but not in human cheek cells.

Thus, the correct answer is: b Components 3 and 4 only.
