How is a cactus adapted living in the desert?

Answer 1

It can absorb and retain lots of water in a short time for later use

It performs photosyntesis in a CAM system which saves lots of water

It keeps the stomata closed during the day and absorbs CO2 at night

It's leaves are thorns and the stem performs photosyntesis

It's bloom is aimed at desert insects

Answer 2

Cacti have adapted to desert environments by storing water in their thick, fleshy stems to survive long periods of drought. Their spines reduce water loss by providing shade and decreasing air flow around the plant. Additionally, their shallow root systems help them quickly absorb water after rare rainfall events.

Answer 3

Cacti can live in the desert because, inside of the cactus there is a water system which stores water into the cactus from the ground. The roots are very long so they go deep into the ground to get water. When explorers are in the desert they tear open a cactus to get water, but they had to be careful of those sharp spikes [Because cacti has a waxy covering!!! also they have the really sharp spikes so no other animas can take th water that they struggle to get, as if they even try to, they will get pricked very hard!

Answer 4

A cactus is adapted to living in the desert because it has no leaves and a small surface area so it reduces the water loss and a thick stem to store water in a drought. A cactus has very long roots to absorb water very quickly and spikes to stop animals from eating it.

Answer 5

The leaves have evolved into spines which protect the cactus from animals desiring to eat it. Having no leaves also slows transpiration of water from the plant enabling it to survive better in an arid environment.

Answer 6

Cactus's have many adaptions to survive in dry, hot regions. Such as:

- Being greyish/silver in color: To reflect heat of the sun and reduce water loss

- A swollen stem: To store water

- Rolled up leaves (only in certain cactus's) to reduce surface area that is exposed to the sun, therefore preventing water loss

- Covered in thorns: Helps protect the plant from animals trying to eat it

Hope that helps!

Answer 7

The Cactus' roots are extremely long so that they can suck water up from far away and search for the water. They also have a shallow root system to absorb surface water when there is some rain (or even dew).

The trunk of the Cactus is also a part of this as it acts as a storing place for the water.

The Cactus' spikes are specially there so that insects and animals don't eat it; the spikes are modified leaves, this reduces the amount of water lost through transpiration.

Answer 8

because a cactus is a plan that stores with water inside of it. it is possible because like never in the desert it rains but, the cactus is just stored with water.

Answer 9

The Leaves of Cactus are prickly and sharp. Cactus have leaves like this to prevent predators and other animals to eat them.

Answer 10

They are just badman to look at with an attitude to match!
