Best Answer

The genome contains several genes, all of which do not have to be switched on simultaneously. When a cell has to become specialized, it has to switch on certain genes and switch off the transcription of others. This mechanism of keeping a check on the genes being expressed at any point of time is referred to as gene regulation. A neuron, for example, will have a certain set of genes switched on, which is different from the genes switched on my a sarcomere (muscle cell).

The cells that monitor the size of stomata are the?

Guard cells are the specialized cells that monitor and regulate the size of stomata in plant leaves. They control the opening and closing of stomata to regulate gas exchange and water loss in the plant.

What are the specialized cells of a female?

Some specialized cells in females include ova (eggs) produced by the ovaries, which are responsible for reproduction. Additionally, cells in the breast tissue produce milk during lactation. Hormone-producing cells in the ovaries and adrenal glands help regulate the female reproductive system.


Are guard cells alive or dead?

Guard cells are alive. They are specialized cells found in the epidermis of plant leaves that control the opening and closing of stomata to regulate gas exchange and water loss.


Why are specialized cells dependent on other specialized cells?

Specialized cells are dependent on other specialized cells because they often need specific signals, nutrients, or support from other cells to function properly. Different cell types have unique functions that contribute to overall tissue or organ function, so they must work together in a coordinated manner for the body to operate efficiently.

How are glandular epithelium formed?

Glandular epithelium is formed through a process called glandular differentiation, where epithelial cells undergo specialized changes to become glandular cells. This differentiation involves the expression of specific genes that regulate the formation and function of glands within the epithelial tissue. The glandular epithelium is characterized by the presence of secretory cells that produce and release substances such as hormones, enzymes, or mucus.


What surrounds the stoma of a plant?

The stoma of a plant is surrounded by two specialized cells called guard cells that regulate its opening and closing. These guard cells control gas exchange and water loss in the plant.


What are 3 ways that leaf cells are specialized?

Chloroplasts: Leaf cells contain a high number of chloroplasts that are specialized for photosynthesis, allowing the cells to convert sunlight into energy. Stomata: Leaf cells have specialized structures called stomata that regulate gas exchange, allowing for the uptake of carbon dioxide and release of oxygen. Thin shape: Leaf cells are thin and flat in shape to maximize surface area for light absorption and gas exchange.
