Why are cactus stems usually very thick?
Cactus stems are very thick because they store water.
Is it true that The stem of the cactus is too thick to hold water?
No, actually the stem of a cactus is adapted to store water. The thick stem allows cacti to survive in dry desert climates by storing water for extended periods of time.
How are cactus adapted to store water in the desert?
Their stems are thick and sponge-like.
Fact about cactus?
An interesting fact about a cactus is that a cactus has a thick, juicy and swollen stem inside his body which helps it to store water and when it gets thirsty because of the extremely hot weather, he can drink the water anytime he wants.
Is the thick outer layer an adaptation that helps a cactus reproduce?
No, the thick outer layer of a cactus doesn't help a cactus reproduce. Its main purpose is the prevention of evaporation or water loss from the cactus' inside contents of water, nutrient solutions, and energizing photosynthetic products. Instead, the most common forms of reproduction among cactus plants tend to be by their seeds, their jointed parts falling off and rooting, or their baby offsets.
Are cactus plants trees?
They are succulent plants, having thick fleshy leaves or stems to store water
Why are leaves modified to form spines in the cactus plant how then does the cactus plant make food?
The cactus adapted to its harsh environment by developing thick skin to slow the evaporation of water. The leaves changed in order to reduce the surface area that water could evaporate from and over time became defensive spines to protect itself from animals trying to get inside its thick skin for the moisture. The cactus makes its food, by having chlorophyll throughout the rest of plant. That is why the entire cactus is green.
Why do cactus have a thick waxy skin?
it slows down the loss of water
What is cactus that stores water in its stem called?
A cactus that stores water in its stem is called a stem succulent. The stem has tissues that are capable storing large quantities of water. The stem also has a thick waterproof epidermis covered by a waxy cuticle that prevents loss of water due by evaporation. Examples of stem succulents - Cardon Cactus, Organ Pipe Cactus, Saguaro Cactus
What is cactus water?
It's water from a cactus! The cactus has collected that water!x
Why does a cactus have thick stem?
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.
Why does a cactus grow so slow?
Cactus grow very slow because it is saving water for the later time. Cactus grow in the desert, and it merely rains in deserts. So, when it does rain, the cactus takes up as much as water as it can and saves it for the rest of the period of time until it rains again, which is why they grow slowly. They use small amounts of water for itself everyday, which makes it grow slower.
