Q3 Plants adapt themselves to the environment in which they live Identify the geographical habitat of plant by obsering the foowing characters bes lot of branches and small compound nodified leaves. it can withstand summer heat ) It sheds its leaves in the autumn Q 4 If desert plants have spiny leaves then what kind of leaves are present in aquatic plants with leaves floating on the surface of water Q.5 Which types of plants are found on hilly areas?​

Answer 1

Answer:

1) A, B, and C

2) Plants growing in drier conditions tend to have less No of stomata on their leaves because they absorb water from their roots and to survive in dry areas they need to decrease transpiration to limit their water loss.

Answer 2

Answe:

Ability of plants to live in hot, dry or cold areas is called adaptation. Plants develop adaptations

that help them to live and grow in different areaseven with extreme conditions. Cactus having

needle like leaves with long roots, fleshy stem with green color and require very low amount of

water to survive. WhereasPinus tree also having needle like leaves and covered with thick layer

of cuticle. Both these plants having some similarities although both are present in different

habitat.

Q3.1 Adaptation in desert plants are shown by the presence of

A) Broad surface leaves

B) Spiny leaves

C)Non green leaves

D)None of the above

Q3.2 Plants growing in drier condition tend to have less no. of stomata on their leaves. Why?

Q3.3 Plants adapt themselves to the environment in which they live. Identify the geographical

habitat of plant by observing the following characters.

I) It has lot of branches and small compound / modified leaves.

ii)It can withstand summer heat

iii)It sheds its leaves in the autumn

Identify the type of plant.

Q3.4 If desert plants have spiny leaves then what kind of leaves are present in aquatic plants

with leaves floating on the surface of water.

Q3.5 Which types of plants are found on hilly areas?
