Auxins also play a part in phototropism, an occurrence that involves plants bending or moving away from light. The shoot tip is responsible for directional movement by the plant in response to sunlight, as this is the area where auxins can be found. What is centripetal force easy definition?
Give a brief definition of Hyperkalemia. Define the following word: "phototropism". Define the following word: "anerythropsia". Briefly define biology. Provide the definition for phenotype. What does biology mean? What is the formal definition of Biology?
Explain what a covalent inhibitor is. What are some examples? Describe the difference between covalent and ionic bonding. Explain phototropism. Describe the toxic effects of mercury and its compounds and explain how we are exposed to these toxins. Briefly describe what is Tay-Sachs and explain its...
What is responsible for leaf growth? The term auxin is derived from the Greek word auxein, which means “to grow.”Auxinsare the main hormones responsible for cell elongation in phototropism and gravitropism. They also control the differentiation of meristem into vascular tissue, and promote leaf ...
They also exhibit some form of limitedmovementlike the unidirectional movement of plant parts in response to light, orphototropism, and the folding of the leaves ofMimosain response to touch. 4. The life cycle of plants consists of a distinctalternation of generations. ...
What is red snow phenomenon ? View Solution What does the torque do? View Solution (a) What does a Mimosa pudica plant do in response to touch? What is this phenomenon known as? (b) What happens to the dandelion flower (i) during daytime, and (ii) at night? What is this phenomenon...
” Phototropism, the way plant growth is influenced by light, leads to tree branches in the northern hemisphere growing closer to horizontal on the southern side and closer to vertical on the northern side. This creates a recognizable tick, or check mark, shap...
What is an albino? Do the albino people have melanocytes? Which color of light is the best stimulus for phototropism seen in stems? Explain. What do you see when you put chlorophyll extract in the direct light? What is the source of illumination for a light microscope? What gas do plants...
What is the significance of phototropism in shoots? Phototropism allows shoots to grow towards light, optimizing energy capture for photosynthesis. 10 What is the role of root hairs? Root hairs increase the surface area for water and nutrient absorption. 9 What are some examples of storage roots...
Phototropism is the growth of a plant towards light, regulated by auxin. 13 Can auxin be synthetically produced? Yes, synthetic auxins are used in agriculture to promote rooting and other growth processes. 9 What is seed dormancy, and how is it broken? Seed dormancy is a period of inactivity...
