deserts plants have swollen stem ,leaves redused to spines and looks different . discuss.?

Question

does this question is correct for the topic' plants adaptation'?
if not plz write an indirect question for the same topic.

Answer 1

it is not actually swollen it is thick .
it is so B'coz as it lives in desert it needs to store water. so it stores water in it's stem, leaves & in spines.. it is also to be noticed that they have long roots too. this helps them to get water from deep

Answer 2

desert plants have swollen stem 2 store water , and the leaves r reduced 2 spines 2 minimise the area of exposure 2 sunlight which inturn reduces the transpiration. these adaptations help them 2 survive in the extreme climates.

Answer 3

yes..its the correct topic..Plants need to conserve moisture and energy in the dry desert. Many plants slow down growth for half of the year to conserve moisture. Many others also lose their leaves when temperatures become too intense. When the short rain season comes, plants burst into color, sprouting leaves and flowers. desert plants like succulent plants n some cactuses can store water in their thick stems and pulpy interior. their growth is also very slow .. Many plants achieve water conservation by losing their leaves in one fashion or another..Shedding leaves not only prevents the loss of moisture from evaporation, but also slows the growth of the plant. Slowing growth helps plants use less water, food, and energy during hot seasons. A large number of desert plants begin as seeds. Seeds can survive without water for indefinite periods of time..Other plants don thin, knife-like leaves that prevent water loss by giving the sun a smaller area to evaporate water. all these r adaptations of desert plants to survive in that environment.

Answer 4

swollen stem,leaves reduced to spines looks different in desert plants becoz it reserves water and holds for long time as it reduced its surface area.it is also covered by cuticle coating which also helps in reducing transpiration.The main phenomena of this is to substains its life in dry areas by holding its require foods and water supplying for growth,development,reproduction etc.this all makes a different from any others moderate plants.Of course there may be some exceptional plants.

Answer 5

properly, with the wasteland, the main concern is loss of water, and being interior the warmth, the % is bigger. enable's take as an occasion, the glaring one - the cactus, a trouble-free xerophytic (adapted to destructive water supplies) plant. The leaves in this element are the pricks on the exterior - they are tiny, with the intention to shrink the fee of transpiration - the stream of water by ability of the roots/xylem/leaves from the backside to the right of the plant, and out. Why? because of the fact transpiration wastes watter. additionally they have sunken stomata - stomata are the holes the place extra water no longer used for growth/restore purposes escapes after transpiration. There are additionally in basic terms a number of them. those factors of them ability that's tougher for water to flee - actually, they shop any extra water interior the plant for whilst mandatory. additionally, the waxy cuticle on the exterior of the cacti is thick in maximum places, to furnish a water-resistant later so little water can get away. Their roots are additionally very shallow, as a result on the part of the exterior, and wide - small cacti could have roots with a (floor) floor part of two-4 metres. additionally they have the flexibility to enhance in direction of water supplies to get the water from it, a xerophytic version. that's approximately all i be attentive to. wish it helps! :P

Answer 6

The swollen stems just have plenty of water for them to survive and spines so that water doesn't evaporate right?

Answer 7

plant modifications.
swollen stem-as they store water.
leaves reduced-to prevent transpiration
spines-as a defense mechanism
yup the question is correct

Answer 8

Yes, it is correct topic for plant adaptation. You could also include plant's terrestrial modifications also.

Answer 9

These kind of modifications are called phyllochade, cladode , or phyllod

Answer 10

Yes, it is al ltrue. they also have chlorophyll in the stems.
