Mention three adaptations found in plants to reduce transpiration
Three adaptations found in plants to reduce transpiration are as follows:
1. The leaves are covered by a thick cuticle: In evergreen plants, such as banyan, the
leaves remain covered by a thick waxy cuticle. This reduces the rate of transpiration.
2. Reduced number of stomata: The reduced number of stomata in the upper epidermis greatly reduces transpiration.
3. Narrow leaves: The leaves become narrower so as to reduce the surface area. In
some cases, the leaves are modified into spines as in xerophytic plants.
The diagram given below is that of a developing human foetus in the womb. Study the same and then answer the questions which follow:
(i) Name the part labelled 1.
(ii) Mention any two functions of the part labelled 2.
(iii) Explain the role played by the part labelled 3.
(iv)What is the normal gestation period (in days) of the developing foetus?
