Cytokinin
What else can I help you with?
What helps plant cells divide and is located primarily in roots and fruits?
Cytokinin is a plant hormone that plays a vital role in cell division. It is primarily found in roots and fruits, where it regulates cellular processes such as growth and development.
Where do the cells divide to produce hair?
Hair cells divide in the hair follicle, which is located in the outer layer of the skin called the epidermis. The hair follicle contains stem cells that divide and differentiate to produce new hair cells, eventually forming the hair shaft that grows out of the skin.
When we grow do our cells grow or divide?
Cells divide.
What are the two sources of new cells after a sunburn?
After a sunburn, new cells primarily arise from the skin's basal layer, where stem cells are located, and from surrounding healthy skin cells that migrate to the damaged area. The basal layer generates new keratinocytes, which proliferate and differentiate to replace the injured cells. Additionally, the inflammatory response to the sunburn can stimulate surrounding cells to divide and help repair the damaged tissue.
Do skin cells divide?
yes. all skin cells divide and divide and divide all over your body.
Where within the epiphyseal plate is the dividing cartilage cells located?
The dividing cartilage cells are located in the zone of proliferation within the epiphyseal plate. This zone is where chondrocytes actively divide and contribute to bone growth.
Do Cells diving indefinitely?
Cells do not divide indefinitely; they have a limit to the number of times they can divide, known as the Hayflick limit. This limit is primarily due to the shortening of telomeres, which protect chromosome ends during replication. Once telomeres become too short, cells enter a state called senescence or undergo programmed cell death (apoptosis). However, certain cells, like cancer cells, can bypass these limits and divide uncontrollably.
What certain cells divide only if damaged?
Certain cells, such as liver cells (hepatocytes) and certain types of stem cells, have the ability to divide primarily in response to damage or injury. These cells remain in a quiescent state under normal conditions but can rapidly proliferate when tissue repair is needed. This capacity for division allows them to restore function and maintain tissue homeostasis after damage.
Why do divide?
There are numerous reasons why cells divide. If someone skins their leg, for example, cells will divide for the purpose of replacing cells that have been damaged.
Where are chloroplasts located within plant cell?
Chloroplasts are located within the cytoplasm of plant cells, specifically in the mesophyll cells of leaves. They are also found in other green parts of the plant, such as stems and unripe fruits.
What are three 7th grade reasons cells divide?
cells divide because of: -growth -development -repair
Is it important for cells to divide?
If cells do not divide properly, then many problems can occur, cancer cells for example.
