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 3 and 4 only
b
Components 1 and 5 only
c
Components 2 and 3 only
d
Components 1, 2, and 3 only
The correct answer would be:
a) Components 3 and 4 only.
Chloroplasts can be observed in leaf epidermal cells as they are responsible for photosynthesis. The cell wall can also be observed in plant cells, but not in animal cells like human cheek cells.
The correct answer is option c: Components 2 and 3 only.
Components 2 and 3, which are the nucleus and chloroplasts, could be observed using a microscope in a prepared slide of leaf epidermal cells. In contrast, a prepared slide of human cheek cells would not have chloroplasts as they are only found in plant cells. However, both leaf epidermal cells and human cheek cells have components 1 (cytoplasm) and 5 (cell membrane). Therefore, the components that could be observed in a prepared slide of leaf epidermal cells but not in a prepared slide of human cheek cells are components 2 (nucleus) and 3 (chloroplasts).
