Guard cells become swollen and turgid when water enters them through osmosis, usually in response to favorable environmental conditions like high humidity or sufficient soil moisture. This swelling causes the stomata to open, facilitating gas exchange for photosynthesis. Conversely, when conditions are dry or when the plant needs to conserve water, guard cells lose water and become flaccid, causing the stomata to close. This regulation helps the plant maintain homeostasis and optimize water use.
What else can I help you with?
By secreting hormones the tymus causes what cells to become immunocompetent?
The thymus causes T lymphocytes (T cells) to become immunocompetent by secreting hormones that promote their development and maturation process.
When plant cells are swollen with water they are what?
Plants swell when hypertonic in hypotonic solutions of impermeable materials
What is the term for the changes that take place in cells as they develop?
The term for the changes that take place in cells as they develop is called differentiation. It causes cells that are not very specialized to become cells that are very specialized.
What is the most likely affect on the plant if the guard cells stay swollen on a hot day?
Increase intherate of transpiration
Placing plant cells in a hypotonic solution causes the osmotic pressure to?
Placing plant cells in a hypotonic solution causes osmotic pressure to increase as water enters the cells. This influx of water leads to turgor pressure, which helps maintain the structural integrity and rigidity of the plant cells. As the cells swell, they become turgid, supporting the overall stability of the plant. However, if the pressure exceeds the cell wall's capacity, it could lead to cell lysis.
When you have an infection the buildup of white blood cells causes what to be swollen?
lymph node
Why do people have swollen lymph nodes when they are sick?
More white blood cells are being produced
Why does the swollen cells in a stoma bend?
A stoma comprise of two cells, called gaurd cells. Each of these gaurd cellwall is thick around the pore, so when gaurd cells are swollen, these bend towards the pore making the stoma open. The bending happens due to turgidity of gaurd cell and their unequal thickness of cell wall.
What causes diseaeses?
It's when cells in the body become uncontrollable.
By secreting hormones the tymus causes what cells to become immunocompetent?
The thymus causes T lymphocytes (T cells) to become immunocompetent by secreting hormones that promote their development and maturation process.
What type of disease causes the white blood cells to become prolific?
leukemia
What is the term for the changes that take place in cells as they developed?
The term for the changes that take place in cells as they develop is called differentiation. It causes cells that are not very specialized to become cells that are very specialized.
Should you use hot or cold compresses for a swollen eyelid?
ONLY USE COLD WATER for a swollen eyelid. Hot water stimulates the cells and makes it more swollen.
What characterises a cancer promoter?
A cancer promoter causes cells with DNA mutations to multiply and become tumors.
When plant cells are swollen with water they are what?
Plants swell when hypertonic in hypotonic solutions of impermeable materials
Why does Rubella causes swollen lymph nodes?
Rubella, or German measles, causes swollen lymph nodes as part of the body's immune response to the viral infection. The virus triggers the activation of the immune system, leading to lymphadenopathy, which is the enlargement of lymph nodes. This occurs because lymph nodes are responsible for filtering pathogens and producing immune cells, causing them to swell when fighting off the virus. Swollen lymph nodes are a common symptom in many viral infections, including rubella.
Why growth hormone deficiency causes hYpoglycemia?
Growth hormone and insulin are both needed to uptake amino acids into cells. In GH deficiency cells produce more insulin receptors and become more sensitive to insulin. This causes increased uptake of glucose into cells.
