Reflex action is a nerve mediated, automatic involuntary response to a stimulus without consulting the will. It is controlled by spinal cord. it needs an instantaneous response to a stimulus where delay can be harmful. On the other hand, walking in a straight line is a conscious, voluntary response.Read more
Reflex action is a nerve mediated, automatic involuntary response to a stimulus without consulting the will. It is controlled by spinal cord. it needs an instantaneous response to a stimulus where delay can be harmful. On the other hand, walking in a straight line is a conscious, voluntary response. It is controlled by a part of hind-brain called cerebellum. It does not need an instantaneous response.
Opening and closing of stomata occurs due to turgor changes in guard cells. Moreover guard cells have differentially thickened walls i.e., outer walls are thin and inner walls are thick. Absorption of water causes guard cells to swell up and get curved out resulting in the opening of stomatal pore wRead more
Opening and closing of stomata occurs due to turgor changes in guard cells. Moreover guard cells have differentially thickened walls i.e., outer walls are thin and inner walls are thick. Absorption of water causes guard cells to swell up and get curved out resulting in the opening of stomatal pore whereas during flaccid condition, shrinking of guard cells takes places that causes closure of stomatal pore.
Autotrophic nutrition or photosynthesis is a process by which organic food is manufactured from inorganic raw materials. The basic requirements for the photosynthetic process are chlorophyll,carbon dioxide, water and light. During this process oxygen and water are produced as by-products.
