What else can I help you with?
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.
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.
How is plant growth controlled?
plant growth controlled by hormone called auxin which is found in roots and shoots and sunlight break down auxin answered by rasool ebrahimi
Is chlorophyll controlled from the bottom up or from the top down?
Chlorophyll production is regulated from the top down, meaning it is controlled by external factors like light intensity, temperature, and nutrient availability that influence plant growth and photosynthesis. These factors impact the plant's ability to synthesize chlorophyll for photosynthesis.
What is Photosynthesis controlled by?
Photosynthesis is primarily controlled by environmental factors such as light intensity, carbon dioxide concentration, and temperature. Enzymes and proteins within plant cells also play a crucial role in regulating the process of photosynthesis. Additionally, genetic factors can influence the efficiency and speed of photosynthesis in plants.
Define plant crop anatomy and physiology?
Plant crop anatomy is the study of how plants are structured. Plant crop physiology is the study of fundamental processes such as photosynthesis, respiration, plant nutrition, and hormones in plants.
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 can the measuring rate of photosynthesis be accurately determined in a controlled experiment?
The rate of photosynthesis can be accurately determined in a controlled experiment by measuring the amount of oxygen produced by the plant over a specific time period. This can be done using a device called a gas exchange analyzer, which can track the changes in oxygen levels in a closed system where only the plant is present. By monitoring the increase in oxygen concentration, scientists can calculate the rate of photosynthesis occurring in the plant.
When a plant grows as mediated by growth hormones which main plant organs are at work?
When a plant grows in response to growth hormones, the main organs involved are the roots, stems, and leaves. Roots absorb water and nutrients from the soil, while stems support the plant and facilitate the transport of hormones and nutrients. Leaves are crucial for photosynthesis, producing energy that fuels growth. Together, these organs respond to growth hormones like auxins, gibberellins, and cytokinins to regulate various growth processes.
What is a plant that does not use its leaves for photosynthesis?
No plant does not photosynthesis
Is either photosynthesis of respiration controlled by enzymes?
respiration is but photosynthesis isn't.
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.
