Question

'Guard Cells' are found in

• A. lung
• B. liver
• C. stomata
• D. heart

Hint:

Remember: Guard cells are responsible for opening and closing the stomata, controlling gas exchange and water loss in plants.

Answer 1

The Correct Option is C

Step 1: Understanding Guard Cells
Guard cells are specialized plant cells that surround stomata (the pores on the surface of leaves and stems). They regulate the opening and closing of the stomata, allowing for the exchange of gases (such as oxygen and carbon dioxide) and controlling water loss through transpiration.

Step 2: Identifying where Guard Cells are found
- Guard cells are found in the stomata, which are tiny pores located on the surface of plant leaves and stems.
- Guard cells are not found in organs like the lung, liver, or heart, as these are animal structures.

Step 3: Conclusion
Thus, guard cells are found in the stomata of plants.
\[ \boxed{\text{stomata}} \]
