Guard cells are specialized cells located on the surfaces of plant leaves and stems that regulate the opening and closing of stomata. These cells control gas exchange by changing shape in response to environmental conditions, allowing carbon dioxide to enter for photosynthesis while minimizing water loss through transpiration. The features of guard cells, such as their flexible cell walls and the presence of chloroplasts, enable them to respond to light, humidity, and internal water levels effectively. This regulation is crucial for maintaining the plant's overall health and metabolic functions.
Guard cells contain chloroplasts for photosynthesis, have a kidney bean shape that allows for stomatal opening and closing, and regulate gas exchange in plants by controlling the size of stomatal pores.
No, not all plants have guard cells. Guard cells are specialized cells found in the epidermis of leaves and stems of plants, particularly in vascular plants, that control the opening and closing of stomata. Non-vascular plants like mosses and liverworts do not have true vascular tissue or stomata with guard cells.
The specialized epidermal cells surrounding the guard cells are called subsidiary cells. These cells play a crucial role in the functioning of the guard cells by assisting in the regulation of stomatal opening and closing, which is essential for gas exchange and transpiration in plants. They help maintain the turgor pressure in guard cells, thereby influencing their movement.
Answer1. Guard cells have chloroplast, epidermal cells do not have.2. Guard cells are much smaller than the epidermal cells.3. The cell walls of guard cells are not uniform, inner walls are thicker than the outer walls. epidermal cells are unformly thin.

The guard cells are specialized cells that control the opening and closing of the stomata in plant leaves. They can change shape to regulate the exchange of gases and water vapor between the leaf and the surrounding environment.

No Guard cells are cells that close when there is dry weather, preventing the leaf from becoming dehydrated

Guard cells change shape to open and close stomata. When they are flaccid, the stoma is closed. When they are full of water and firm, the stoma is open. There are 2 guard cells controlling a stoma. Water enters guard cells by osmosis and they change shape.
The guard cells.
Guard cells contain chloroplasts, which are responsible for photosynthesis, while other epidermal cells do not typically contain chloroplasts. Chloroplasts are important for the production of sugars and energy through the process of photosynthesis in guard cells.
