Best Answer

The leaves of a cactus have been reduced to spines to deter herbivory.

The stems are fleshy and photosynthetic.

The stomata are sunken into the surface of the leaf to increase the boundary layer.

  1. Reduced leaf surface area to minimize water loss through transpiration.
  2. Stem modifications, such as succulence, to store water and perform photosynthesis.
  3. Waxy cuticle to prevent water loss and spines for defense against herbivores.

Is cactus a fern?

no but it is a member of the plant family and their distinctive appearance is a result of adaptations to conserve water in dry and/or hot environments


What structural adaptations would you notice on a cactus?

Some structural adaptations of cacti include reduced leaves or spines for water conservation, a thick stem for storing water, a shallow but extensive root system to quickly absorb water after rain, and a waxy outer layer to prevent water loss.


Why does a root of a cactus help it to survive in its normal habitat?

Cactus roots are shallow and spread out widely to help the plant quickly absorb water in arid environments. The roots also have specialized adaptations, such as the ability to store water and prevent loss through evaporation, which help cacti survive in their dry habitats.


Is there any plant that can survive very harsh conditions which is not cactus?

Yes, there are plants such as the resurrection plant (Selaginella lepidophylla) and the ice plant (Delosperma sp.) that can survive very harsh conditions like extreme temperatures and lack of water without being a cactus. These plants have special adaptations that allow them to withstand such challenging environments.


Why are cactus found in desert region?

Cacti are found in desert regions because they are able to thrive in arid environments due to their ability to store water in their stems and reduce water loss through specialized adaptations like a waxy cuticle and reduced leaf surface area. These adaptations allow cacti to survive in harsh desert conditions with limited water availability.
