Answer:
Following are the seven basic requirements of plants to grow properly.
1) Light: Light is the basic need of plant. With the help of light, photosynthesis occurs.
2)Water: Water is used by the plants as a reactant in making their own food.
3) Temperature: In optimum temperature, plants grow fast.
4) Time: There is proper time for the sowing of every plant.
5) Nutrients: Nutrients are food of plants which are used for their growth and development.
6) Proper place or medium: Plants require a soft nutritious soil for germination.
7) Air: Plants need air because it contains oxygen and carbondioxide which is used by the plants during photosynthesis and respiration.
The given case is an example of reflex action.
The reflex action is an instant involuntary response to a stimuli, which can cause damage. The reflex action takes place through the processing of message through a reflex arc, this reflex arc lack the involvement of brain and the processing of the stimulus takes place in the spinal cord.
In this case, the sensory receptors detects the stimuli and transfer the message to the relay neuron present in the spinal cord through the sensory neuron. The relay neuron transfer the action message to the effector muscles present at the site of stimulus with the help of motor neurons.
Given below is a block diagram of reflex action.
I believe its aggression?
