What is function of Medulla in Hindi-Brain in 10th Science Chapter 6?
Medulla controls all involuntary actions including blood pressure, salivation and vomiting.
How do dendrils cling the support as per Class 10 Science chpater 6?
Tendrils are sensitive to touch. When they come in contact with any support, the part of the tendril in contact with the object does not grow as rapidly as the part of the tendril away from the object. This causes the tendril to circle around the object and thus cling to it.
Why do plants appear to bend towards light according to 10th Science Chapter 6?
When growing plants detect light, a hormone called auxin, synthesised at the shoot tip, helps the cells to grow longer. When light is coming from one side of the plant, auxin diffuses towards the shady side of the shoot. This concentration of auxin stimulates the cells to grow longer on the side of the shoot which is away from light. Thus, the plant appears to bend towards light.
Name the hormone of plant which inhibits the growth as per 10th Science NCERT?
Abscisic acid is one example of a hormone which inhibits growth of plants.
