What three body structures help cactus plants survive in dry climates?

Answer 1

the waxy cuticular & spiny covering from outside

Answer 2

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.

Answer 3

# 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.

Answer 4

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.

Answer 5

Cacti have thick, fleshy stems for storing water, reduced and waxy leaves to prevent water loss through transpiration, and spines for reducing water loss and providing shade.

Answer 6

tiny and few leaves to check transpiration

spines to protect from grazing animals.

Green and flashy stem for photosynthesis and food storage.

Answer 7

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.

Answer 8

itn helps it by protecting its body fron preditors

Answer 9

They store water in there stem.

Answer 10
