In land plants the guard cells differ from other epidermal cells in having
A
Chloroplasts
B
Cytoskeleton
C
Mitochondria
D
Endoplasmic reticulum
Detailed Solution
Each stoma is bounded by two bean-shaped guard cells (dumb-bell shaped in grasses).
The guard cells possess chloroplasts and regulate the opening and closing of stomata.
The other epidermal cells are parenchymatous cells with a large vacuole and generally lack chloroplasts.
Cytoskeleton, mitochondria and endoplasmic reticulum are present in all living epidermal cells, so they are not distinguishing features.
Hence guard cells differ from other epidermal cells in having chloroplasts.
