How is cactus adapted to survive in a desert? Give a labeled diagram of cactus to support your
answer.
Answers
Answer:
Cacti live in a desert environment where rain is rare, and even if it does rain, due to the heat water will simply evaporate. To cope with this Cacti have adapted allowing them to survive in the extreme desert climate.
Cacti have a widespread root system (made up of fibrous roots) that can allow them to collect water from a large area.
Root hairs grow on fibrous roots collecting even the smallest droplets of water. After the ground dries the hairs will die meaning the cactus wouldn't have to use extra energy to maintain them.
Cacti also have spines (the prickly thorn like things) in which replace leaves. These spines minimise the surface area of the cactus reducing water loss.
The cacti’s stem is also thick and fleshy allowing it to store a lot of water. The stem also has a waxy waterproof kind of coating to help retain more water.
The spines can also act as a form of defence against animals that potentially may eat them. Hope that helps!
Explanation:
Answer:
The stomata of many cacti lie deep in the plants' tissues. This adaptation helps cacti reduce water loss by keeping the hot, dry wind from blowing directly across the stomata. The leaves and stems of many desert plants have a thick, waxy covering. ... Small leaves mean less evaporative surface per leaf.
