Q. What energy is needed by photosynthetic organisms during the process of photosynthesis?
During the process of photosynthesis, cells use carbon dioxide and energy from the Sun to make sugar molecules and oxygen. These sugar molecules are the basis for more complex molecules made by the photosynthetic cell, such as glucose.
Q. How do photosynthetic organisms use light energy to combine carbon dioxide and water?
photosynthesis, the process by which green plants and certain other organisms transform light energy into chemical energy. During photosynthesis in green plants, light energy is captured and used to convert water, carbon dioxide, and minerals into oxygen and energy-rich organic compounds.
Q. What by product of photosynthesis is derived from water and air?
Photosynthesis is the process in which light energy is converted to chemical energy in the form of sugars. In a process driven by light energy, glucose molecules (or other sugars) are constructed from water and carbon dioxide, and oxygen is released as a byproduct.
Q. How do plants resist disease?
Plant disease resistance protects plants from pathogens in two ways: by pre-formed structures and chemicals, and by infection-induced responses of the immune system.
Q. How do plants defend themselves from predators?
To keep small predators at bay, many plants have a mat of fine hairs on the surface of their leaves. To deter larger animals some plants have sharp spines or thorns, while others have leaves that sting or are bitter to taste.
Q. How does a plant respond to its environment?
Plants respond to their environment. They grow toward light. Plant leaves bud and seeds germinate when the temperature is right. Their roots and stems grow in certain directions in response to the pull of gravity.
Q. Does the nettle protect itself against a plant predator?
Stinging nettles (Urtica dioica) grow a bristling fur called trichomes, which are pointed structures that shield the plant from hungry predators.
Q. Which tree has thorns to protect itself from plant eating animals?
Several species of South American and African acacia tree both house and feed aggressive ants. The stinging little soldiers make their barracks inside swollen thorns and feed off of food bodies produced by the plant especially for them.
Q. Which plant have stinky smell that drives away their enemies?
But Musah has found that the roots of some species actively release their foul smell. Her team made this discovery while growing seedlings of Mimosa pudica, known for its sensitive leaves that fold up when touched.
Q. What do you call the spines and thorns of some plants which they used to protect themselves from danger?
Answer. 1. Barrel cactus. The barrel cactus is found in desert regions of North America. …
