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.

What desert plant has no leaves but has stems and spines?
A cactus has no leaves but does have a stem.
What are cacti thorns useful for?
Cactus spines prevent moisture loss from plants. Spines also defend the plants from grazing animals. The spines are just modified leaves.
Why are spines the leaves of cactus plant?
Can be used for rainsticks. The spines are pushed to the inside of the hollow cactus and shells are put in making the sound of rain when inverted. Spines pushed in so the shells don't fall too fast.
What desert plant has no leaves but has stem nd called spines?
Cactus
Which part of the plant do the spines represent?
Spines on a plant typically represent modified leaves or stipules that have evolved to protect the plant from herbivores or help it conserve water.
What are the modified leaves of a cactus?
Cactus leaves are modified, because they're characterized by smaller surface areas. Those cactus plants that have modified leaves have them as thorns, spines, spikes, quills, prongs or bristles. So the cactus leaf has a narrower, thinner look than the leaves of deciduous plants.The reason for this modified look is the effort to keep water loss to a minimum. Water is lost at a lower rate and in smaller quantities over a smaller surface area. Additionally, the narrower, thinner look helps the modified leaf to direct any available moisture on its surface to drip to the ground. On the ground, the drops seep into the soil, where they can be taken up by the cactus plant's network of fibrous, shallow roots.
Which is the part of cactus plant modified into spine?
In cacti, the leaves are modified into spines. This adaptation helps reduce water loss by minimizing surface area and provides protection against herbivores. The stem of the cactus, which is typically thick and fleshy, is responsible for photosynthesis and water storage.
Which plant has flowers but no real leaves?
A Cactus - it has a modified stem which produces flowers, but no leaves.
Is cactus leafy plant?
yes, it is, the leaf of a cacti plant is modified into spines in order to reduce transpiration. This is a method of desert adaptation.
What is the meaning of leaves reduced to spines?
Cacti have spines. Evolutionary theory is that the spines were originally leaves, but which reduced in size and form to carry out a new function, as spines, to protect the plant from predators. According to the same theory the stem of the plant became the gas exchange and the 'chlorophyll-containing' 'photosynthesis' part of the plant, thus replacing the functions formerly carried out by and through the leaves.
Various types of modified leaves?
The cactus modified leaves to sreate its spines, which are used for protection and storage of water. Carniverous plants have the "mouths," which are modified to help the plant obtain its needed nitrogen. Coniferous trees created needles instead of leaves. These needles are used for water storage and photosynthesis, and they have a very thick cuticle.
Why cactus plant have spines?
