Give shape of guard cells in dicotyledonous plants.
GeneralClass 12AllAnswered 27 Mar 2026
Answer
Guard cells in dicotyledonous plants are kidney-shaped (or bean-shaped). Their unique structure, with:
- Thicker inner (ventral) walls
- Thinner outer (dorsal) walls
- Radial arrangement of cellulose microfibrils
...enables the opening and closing of stomatal pores through changes in turgor pressure.
Contrast: In monocots (grasses), guard cells are typically dumbbell-shaped.
