Cacti are well adapted for survival in the desert. … The spines also protect the cacti from animals that might eat them. Very thick, waxy cuticle to reduce water loss by evaporation . Reduced number ofstomata to reduce water loss by transpiration .
Beside above, what are the 3 types of adaptations?
There are three different types of adaptations:
- Behavioural – responses made by an organism that help it to survive/reproduce.
- Physiological – a body process that helps an organism to survive/reproduce.
- Structural – a feature of an organism’s body that helps it to survive/reproduce.
Also know, how is a cactus adapted for photosynthesis? Cacti are plants that have succulent stems, pads or branches with scales and spines instead of leaves. … All plants photosynthesize, collecting carbon dioxide through holes in their leaves called “stomata” and converting it into sugar and oxygen. Cacti utilize CAM photosynthesis, a process unique to succulents.
In this manner, why do cacti survive in deserts?
A cactus has special adaptations in its roots, leaves as well as stems that enable it to thrive in desert environments. These adaptations include – spines, shallow roots, deep-layer stomata, thick and expandable stem, waxy skin and a short growing season.
Why do cactus stomata open at night?
Cactus and many agaves evolved adaptation to extreme heat and drought by keeping their stomates closed during the day so there is no moisture loss. The CAM metabolism allows the cactus to open stomata at night to take in carbon dioxide so all gas exchange is completed before when the sun rises.

There are two main types of adaptation: physical and behavioral. Physical adaptations are special body parts that help a plant or animal survive in an environment.
Some examples of structural, physiological and behavioural adaptations include:
- Blends in or camouflages with environment.
- Tough skin/scales on back.
- Spiny/horned skin.
- Blood squirting out of eyes.
- K9 repellent chemicals.
The leafless, spiny stem is the characteristic feature of the majority of cacti (and all of those belonging to the largest subfamily, the Cactoideae). The stem is typically succulent, meaning it is adapted to store water.
Cacti is the best in reducing radiation and bacteria.
In addition, cacti absorbs carbon dioxide at night to release oxygen. Putting cacti in the room is helpful in sleeping and supplementing oxygen.
