the waxy cuticular & spiny covering from outside
Survival in dry climates depends upon taking in precious water. Water intake begins with a cactus plant's spreading, shallow, fibrous roots that seek out and take in available soil moisture and dissolved nutrients.
Water intake continues with a cactus plant's storage units being located in the stem, where it's needed most. A cactus plant thereby eliminates the loss in energy, time and work of shuttling water and watery products and solutions back and forth between the below ground roots and the above ground shoots. At the same time, it eliminates the loss of water by the stem being encased in a thick, water loss resistant covering and defended by guard cells on either side of the stem's breathing pores, or stomata. It's by the openings of the stomata that gases such as carbon dioxide are brought inside, and others such as oxygen are released into the outside air.
And the cycle starts all over again with the cactus plant's modified leaves in the form of thorns, spines, spikes, quills, prongs, needles, hairs, or bristles. The modified leaves direct any available moisture - be it dew, fog, or rainfall - into the ground, for adding to the water table and being taken in all over again by the roots.
# The plant body has a thick cuticle to reduce the rate of transpiration. # The stomata are sunken to reduce the rate of transpiration. # The leaves are reduced to spines to reduce the rate of transpiration. # The root system is well developed so as to absorb water efficiently.
One adaptation that's behind desert survival is a cactus' thick outer skin that keeps water, nutrient solutions, and energizing photosynthetic products inside. Another adaptation is a cactus' spreading, shallow, fibrous roots that quickly catch surface and soil moisture. Still another adaptation is a cactus' modified leaves in the form of thorns, spines, spikes, quills, prongs, needles, hairs, or bristles. The modified leaves direct any available moisture - be it dew, fog, or rain - into the ground, to be added to the water table or taken in by the plant's roots.
tiny and few leaves to check transpiration
spines to protect from grazing animals.
Green and flashy stem for photosynthesis and food storage.
in the body of the cactus, water is stored as not much rain falls where cacti are. cacti have thorns to prevent themselves from being eaten by predators.
itn helps it by protecting its body fron preditors
They store water in there stem.
what structures help keep a cactus from losing too much water
thick , waxy steams

Haha yaaa people im not telling u soo lol :) its soo funny and you dont have a definition:)
The main plant that is in the desert is the cactus. Cactus are able to hold water for extended periods of time in order to survive.
they are succulents and retain water in their leaves.
Yes. As long as they have enough water to live in the heat, they can survive. Most plants in deserts, such as cactus`, use different methods to breathe.
date palms , cactus and plants with long roots.
Cactus plants grow in relatively arid climates, and they retain water more efficiently by having thicker structures with a higher proportion of volume to surface area than you would find in other types of plants.
Cactus.
These are cactus like plants, and grow in similar climates.
date palms , cactus and plants with long roots.
Thorns, spines (such as those on a cactus), and prickles are examples of protective structures of plants.

A few. An infamous dessert plant is the cactus.
Flowers help cactus plants survive in the desert by attracting pollinators. Because of pollination, the cactus plants may have fruits full of seeds. For example, the giant saguaro cactus [Carnegiea gigantea] depends upon bats for pollination of its huge, light colored bat blossoms.
