How do plants respond to touch stimuli and what mechanisms are involved in their tactile responses?
Plants respond to touch stimuli through a process called thigmotropism, where they change their growth direction in response to touch. This is controlled by hormones like auxin and ethylene, which help regulate cell growth and movement in response to touch. Additionally, plants have specialized cells called mechanoreceptors that detect touch and trigger a cascade of signaling pathways to initiate a response.
What is the process of long bone growth controlled by?
Long bone growth is primarily controlled by a combination of growth hormone, thyroid hormones, and sex hormones. Growth hormone stimulates bone and cartilage growth, while thyroid hormones regulate overall metabolism which affects bone growth. Sex hormones, such as estrogen and testosterone, play a role in the final stages of bone growth during puberty.
What does cloning crop plants in tissue culture involve?
Cloning of crop plants in tissue culture involves tiny pieces from the parent plant. Sterile agar jelly with plant hormones are needed which makes tissue culture an expensive way of cloning crop plants.
The absorption of water back into the body is controlled by?
The absorption of water back into the body is primarily controlled by the kidneys. They regulate the amount of water reabsorbed into the bloodstream through a process called reabsorption, which helps maintain the body's fluid balance and prevent dehydration. Hormones like antidiuretic hormone (ADH) also play a key role in controlling water reabsorption by the kidneys.
Why do plants need hormones that have the opposite effects?
Plants use hormones with opposite effects to regulate growth processes in response to changing environmental conditions. For example, auxins promote cell elongation while cytokinins promote cell division, allowing plants to balance growth in different directions. This helps plants adapt to their surroundings and optimize their growth and development.
Is flowering in plants controlled by plant hormones?
Plants produce hormones and respond to external stimuli, growing towards sources of water and light, which they need to survive.
Plants grow toward light through the action of?
Plants grow toward light through a process called phototropism. This is controlled by the plant hormone auxin, which causes cells on the shaded side of the plant to elongate, bending the plant towards the light source.
How do hormones effect plants?
okay hormones are in humans....not in PLANTS!!!!*actually plants do have hormones (auxin, ethylene, etc) someone hasn't been paying attention in biology
Is the secretion of pituitary hormones largely controlled by the thalamus?
No, the secretion of pituitary hormones is largely controlled by the hypothalamus. The hypothalamus produces releasing and inhibiting hormones that regulate the secretion of hormones from the pituitary gland. The thalamus is primarily involved in relaying sensory information to the cerebral cortex.
Animal responses can be controlled by the nervous system and?
hormones
Hormones in plants?
Yes.
Does the roots produce hormones?
Phytohormones referred to as plant hormones.Plant hormones are chemical molecules which are produced in plants and cause it to grow. Yes plants produce hormones.
How is the secretory activity of the adenohypophysis controlled?
The secretory activity of the adenohypophysis is controlled by releasing hormones from the hypothalamus. These releasing hormones stimulate or inhibit the release of specific hormones from the adenohypophysis. The hypothalamus communicates with the adenohypophysis through the hypophyseal portal system, which carries releasing hormones directly from the hypothalamus to the adenohypophysis.

What are controlled by hormones?
There are many functions controlled by hormones. Hormones regulate many processes in the body like blood pressure, blood glucose levels, growth and development, and excretion by the kidneys. These are just some of the many processes and systems that the body regulates through hormones. Hormones are usually found as peptides or steroids and act through an intercellular second messenger system.
Is photosynthesis controlled by plant hormones?
No there is no affect. Direct affect is not known
