What else can I help you with?
What A plant response to a stimuli?
Plant growth hormones e.g. IAA.
What does internal stimuli mean in plants?
Stimuli itself is of two types - external stimuli and internal stimuli. External stimuli refers to touch, pressure, heat etc. Internal stimuli refers to the stimuli produced by body components - like hormones etc.
What chemicals coordinate a plant's response to stimuli?
Plant growth hormones e.g. IAA.
What type of chemicals affect plant's growth and development in response to stimuli?
Hormones.
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.
All plant tropisms are controlled by?
It is either one of these four. -Hormones -Chloroplasts -Carbohydrates -The Nervous System. I believe it is Hormones or Chloroplasts. My guess would have to go with Hormones Though.
What is one example of an external and internal stimulus of a plant?
An example of an external stimulus for a plant is light, which influences growth direction through phototropism, causing plants to bend toward the light source. An internal stimulus could be the plant's hormonal response to stress, such as the production of abscisic acid in response to drought, which triggers stomatal closure to conserve water. Both types of stimuli play crucial roles in a plant's survival and adaptation.
How do plant hormones effect human health?
Plant hormones balances the hormones of humans. For example, soybean (Glycine max) affect the level of HDL, also affect the level of blood pressure and sex hormones estrogen due the phytoestrogen concentration of the plant.
What is an internal stimuli of an animal?
This is a very broad question, so a broad answer would be: Internal stimuli will most commonly be automatic reflexes triggered by external stimuli. Example, a drop in temp. will start shivering, cold is felt on the skin a nerve pathway is initiated to the brain triggering follicle stimulation and muscle spasming. Eating more acidic foods (external) will result in the organism producing more bicarbonate to neutralise the acid (internal).
What role do plant hormones play in photosynthesis?
Plant hormones play a crucial role in regulating various aspects of photosynthesis by influencing growth, development, and responses to environmental stimuli. For example, auxins promote cell elongation, enhancing leaf area for more efficient light capture, while cytokinins stimulate chloroplast development and increase chlorophyll production. Additionally, hormones like abscisic acid help manage water stress, ensuring optimal conditions for photosynthesis. Together, these hormones coordinate the plant's overall response to light and other environmental factors, optimizing photosynthetic efficiency.
How does chemical coordination occur in plants?
Chemical coordination in plants is primarily regulated by plant hormones, which are signaling molecules that influence growth, development, and response to environmental stimuli. These hormones are produced in specific tissues and transported to target cells to elicit a response. The main plant hormones include auxins, cytokinins, gibberellins, abscisic acid, and ethylene.
What are the advantages and disadvantages of plant hormones?
Advantages of plant hormones include regulating growth, development, and response to environmental stimuli. They help plants adapt to changing conditions. Disadvantages can arise when hormone levels are imbalanced, leading to abnormal growth patterns or susceptibility to diseases. Overuse of synthetic hormones can also have negative impacts on the environment.
