Q. Guard cells differ from epidermal cells in having :
(a) Mitochondria
(b) Vacuoles
(c) Cell Wall
(d) Chloroplasts
Solution :
Correct option 😀 Guard cells have chloroplasts, whereas epidermal cells usually do not. This is what helps in the opening and closing of stomata. The starch that is present in the guard cells as a result of photosynthesis is metabolized into organic acids in the presence of light, which through the influx of potassium ions ultimately result in the opening of the stoma.
