Question

Give an example of a plant having both kidney and dumb-bell shaped guard cells in stomata.

Hint:

Guard cells can vary in shape between different plant species. Understanding these shapes can help identify plant types and their adaptations.

Answer 1

Step 1: Understanding the structure of guard cells.
Guard cells control the opening and closing of stomata, with different shapes depending on the plant species. Some plants, such as grasses, have kidney-shaped guard cells, while others, such as dicots, can have dumb-bell shaped guard cells.
Step 2: Example.
An example of a plant with both kidney and dumb-bell shaped guard cells in its stomata is "wheat," which exhibits both types of guard cells depending on environmental factors and the plant's developmental stage.
Step 3: Conclusion.
Wheat (Triticum aestivum) is an example of a plant that has both kidney-shaped and dumb-bell shaped guard cells.
