Question

Identify the names of the plants in the picture? Explain

what adaptation have been made to the trunk roots and

leaves in order to survive in the desert or low water area​

Answer 1

Answer:

1)the name of the plant is cactus .cactus is a member of the plant family Cactaceae, a family comprising about 127 genera with some 1750 known species of the order Caryophyllales. The word "cactus" derives, through Latin, from the Ancient Greek κάκτος, kaktos, a name originally used by Theophrastus for a spiny plant whose identity is now not certain.

Spines are a very important leaf adaptation common to all cacti. These modified leaves divert water to the base of the cactus, enabling the roots to absorb the maximum amount of water. Spines keep the cactus cool in the heat by providing shade and protecting the stem from sunburn.The leaves and stems of many desert plants have a thick, waxy covering. This waxy substance does not cover the stomata, but it covers most of the leaves, keeping the plants cooler and reducing evaporative loss. Small leaves on desert plants also help reduce moisture loss during transpiration.

Answer 2

Answer:

Desert plants are either leafless or their leaves are like small needles or have been modified into thorns. As a result, they lose very little water by evaporation. The stem stores water and food and is therefore fleshy The stems are green as they perform photosynthesis in the absence of leaves. Their roots penetrate deep into the soil and some roots spread away into the soil in search of water. There is a thick layer of a waxy substance on the stems of these plants, too.
