Are there chloroplasts in subsidiary cells?
Subsidiary cells do not typically contain chloroplasts. Chloroplasts are found in the guard cells of plant stomata, where they play a role in regulating gas exchange. Subsidiary cells primarily function in supporting and assisting the guard cells in their role in controlling stomatal opening and closing.
Which types of cells contain chloroplasts?
The guard cells of stomata alone contains chloroplast.
Why are the guard cells in the lower epidermis the only cells with chloroplasts in a leaf?
Guard cells in the lower epidermis are the only cells with chloroplasts in a leaf because they play a crucial role in regulating gas exchange and water loss through the stomata. Chloroplasts allow guard cells to photosynthesize and produce sugars, which provide the energy needed for stomata opening and closing. This specialization ensures efficient control over transpiration and photosynthesis in leaves.
Are chloroplast present in guard cells?
Yes, chloroplasts are present in guard cells. Guard cells are specialized cells found in the epidermis of plant leaves and stems that regulate the opening and closing of stomata. Chloroplasts, which contain the green pigment chlorophyll, are responsible for photosynthesis and are necessary for the energy production needed for the opening and closing of stomata.
What two layers of the plant contain chloroplasts?
The mesophyll tissue of the leaf contains chloroplasts as it is responsible for photosynthesis. In addition, the guard cells of the stomata also contain chloroplasts to help regulate gas exchange.

What is the function of a guard cell and when they open?
To regulate opening and closing of stomata

Is it true the tiny holes through which gases enter and exit leaves are called chloroplasts?
They are called stomatas. These are bound by guard cells.
What is the stomata?
---- Stomata are microscopic pores found on the under side of leaves. You will find the stomata in the epidermal tissue. The stomata is bounded by two half moon shaped guard cells that function to vary the width of the pore. Each guard cell contains chloroplasts. The glucose concentration of the the cells changes with the photosynthetic activity and therefore it is the guard cells that regulate the opening and closing of the stoma. ----
What is the function of a guard cell in plants?
The function of the guard cells are that they help to regulate the rate of transpiration by opening and closing the stomata thus preventing excessive water loss.
What two layers of the plant contain chloroplasts?
The mesophyll tissue of the leaf contains chloroplasts as it is responsible for photosynthesis. In addition, the guard cells of the stomata also contain chloroplasts to help regulate gas exchange.
What is tissue packed with chloroplasts?
The stomata in the epidermis allow oxygen, carbon dioxide and water vapour to enter and leave the leaf. The guard cells also contain chloroplasts for photosynthesis.
What organelles are in guard cells?
Guard cells contain typical plant cell organelles such as nucleus, chloroplasts, mitochondria, endoplasmic reticulum, and Golgi apparatus. However, they are particularly notable for having a high density of chloroplasts due to their role in regulating the opening and closing of the stomata for gas exchange and transpiration control.
Are guard cells in a animal cell?
Guard cells are not found in animal cells; they are unique to plant cells. Guard cells are specialized cells located in the epidermis of plant leaves and stems. Their main function is to regulate the opening and closing of stomata, small pores that allow for gas exchange and water loss in plants. The presence of guard cells is crucial for the adaptation of plants to changing environmental conditions.
