CATUS ARE AWSOME. Cacti (plural) is a common name given to a group of xerophytic plants (adapted to dry regions).

They are able to survive to to a number of unique adaptations to their morphology.

They have long roots that spread out just under the surface in search of water, they grow more roots (feeder roots) when heavy rain falls these roots are then cut of by the plant so there is less plant to feed and less chance of precious water seeping out.

They also have spines which are modified leaves to keep animals from eating the stem; the needles also catch water then send it in towards the plant so it can slide of the vertical stem on to the floor to be absorbed by the roots. Reduction in leaves also means less water is lost through transpiration.

Cacti look swollen because they have adapted their stems and leaves (where they still have) to store as much water as possible and to lose as little water as possible by evaporation. They also have a very thick and waxy cuticle which cuts down water loss to the absolute minimum.

The whole of the stem is green and contains photosynthetic cells, so the plant does not need broad leaves to pick up light. There is plenty of light around anyway, so the plant can photosynthesize very well for most of the day.

Some cacti (particularly small ones) have rolled up leaves so there is less surface area exposed to the sun. It may have thorns to protect it from being eaten, and also be a grayish color so to reflect the heat of the sun and to prevent water loss.

How does a cactus survive in the desert?

The cacti (in general) have made many modifications to collect,store and retain water. Adaptations include: . a low surface to volume ratio to reduce evaporation . a waxy outer layer to prevent transpiration of water . a modified CO2 scavenging system to allow CO2 capture withminimum water loss

How is a cactus plant adapted to survive in the desert?

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 deser

How do cactus plants survive in the desert?

Cactus (as most desert plants) plants survive in near desert conditions, on almost no water. They manage this because of several adaptations to their stems and leaves that they have developed over their long evolution. Cacti look swollen because they have adapted their stems and leaves to store a

How are cactus adapted to survive in a desert?

the plants growing in deserts have adaptations to prevent water loss for example cactus: 1. has no leaves to prevent water loss through transpiration. 2. stem is modified in such a way that it performs photosynthesis. 3.root system is well developed and grows in deep in search of water.

How does a cactus help you survive in a desert?

Cactuses are thrifty plants that live in dry regions. They may not get much moisture where they live, but they manage to make the most of what they do get. Since the cactus's long roots lie close to the surface of the ground, they can catch water from desert rains. And since the roots have a cork-li

Why is the desert suited for cactus to survive?

Cactus' have a fleshy inside so when it rains it can hold water when it rains. Their roots either spread out far to collect the maximum amount of water it it rains (covers a large surface) or their roots go deep into the soil to get water from deeper. They have no leaves to minimise their water loss
