A cactus can store water in its fleshy stem and this enables it to survive periods of drought.
The cactus has the ability to store water in its fleshy stem so it can survive long periods of drought.
no
cactus have a hollow stem. it is where they store water and food for survival
Enlarged stems carry out photosynthesis and store water. Unlike many other succulents, the stem is the only part of a true cactus where this takes place. Much like many other plants that have waxy coatings on their leaves, Cacti often have a waxy coating on their stems to prevent water loss. This works by preventing water from spreading on the surface and allowing water to trickle down the stem to be absorbed by the roots and used for photosynthesis. Cacti have a thick, hard-walled, succulent stem - when it rains, water is stored in the stem. The stems are photosynthetic, green, and fleshy. The inside of the stem is either spongy or hollow (depending on the cactus). A thick, waxy coating keeps the water inside the cactus from evaporating.
delicious, pulpy, tasty, fleshy, juicy, cactus
Typically the leaves of the plant play the greatest role in photosynthesis. However, on cacti, the needles are actually modified leaves. These needles are a characteristic of protection and cannot carry out photosynthesis due to little surface area. Therefore, it is the stem that does the photosynthesis for the plant.
Because that is how it stores water for when it needs it.
Yes they do
Cacti have thick, fleshy stems because water is stored in them. The stems are green so that cacti can live by photosynthesis, the process by which organisms containing chlorophyll transform light energy into chemical energy. ... Thick, waxy coating on succulent stems of cacti keeps water from evaporating from inside.
In cactus leaves are absent. Chlorophyll are found in trunk mainly.
The 'spines' of a cactus attach directly to the stem of the plant.
