But they do... cacti leaves look like thorns to us. The reason their leaves evolved into thorns is to reduce water loss.
AnswerThey do have leaves, but they don't look 'normal'. Their leaves are the needle-like things sticking out of the stem, and they attach themselves to your skin to draw blood.
The reason their leaves are not like 'normal' ones, is because of the heath cacti are exposed too. Large leaves are not suitable for hot environments, since they have a large surface, from which water can evaporate. So actually, their leaves are so small and pointy for protection. Protection from water loss, herbivores and birds. After all, cacti don't like being eaten or nestled in, or deprived of all their water. Photosynthesis is also achieved by the stem or body of the plant, not the leaves.

∙ 11y agoThe plants are green because they contain chlorophyll. Chlorophyll provides the plant with the ability to do photosynthesis (Turn sunlight into food). The plants have adapted so that they can utilize all the sunlight that they get in the desert.

What plants manufacture food in their stem instead of leaves?
Leafless cactus plants
Is cactus a leaf or a stem?
Leaves provide extra surface area for water to evaporate out of the plant. In the arid desert, plants need all the water they can get.
What plants store food in stem?
sugarcane
What is considered a modified stem?
1.under ground stem modifications 2.sub-aerial stem modifications aerial stem modifications
What part of the plant makes food in cactus why?
In cactus leaves are absent. Chlorophyll are found in trunk mainly.
What plants manufacture food in their stem instead of leaves?
Leafless cactus plants
What parts of cactus plants and roses make them difficult to hold?
It's the thorns on cactus plants and roses that make them both difficult to hold. On both plants, the thorns serve to defend and protect the stem and the flower. But on the cactus, the thorn is a modified leaf. On a rose, the stem has both thorns and regular leaves.
The plants which can store water in their spongy stem are called what?
A succulent and a cactus both store water in their spongy stem or leaves.
What are the examples of soft stem plants?
grass, mushroom, ginger, pineapple, eggplant, cactus.
How is temperature a limiting factor for cactus plants?
Temperature is a limiting factor for cactus plants, in terms of extremes of heat and cold. For example, desert cactus plants are used to a hot, dry climate. But temperatures may be so high that the available water evaporates.It particularly is the other extreme, of chilling temperatures, that may be fatal for a cactus. Cold may leave a cactus with a range of problems from stem tip damage to actual stem collapse. Cactus plants that are exposed to excess cold or dampness are prone to rot, which softens and blackens tissue.
Why does a cactus have a hollow stem?
cactus have a hollow stem. it is where they store water and food for survival
What are three body structures that help cactus survive in dry climates?
tiny and few leaves to check transpiration spines to protect from grazing animals. Green and flashy stem for photosynthesis and food storage.

What plants store food in stem?
sugarcane
Names of plants that grows from stem cuttings?
onion,ginger,potato,rose,bougainvillea,cactus,hibiscus,sugarcane,jasmine
What is considered a modified stem?
1.under ground stem modifications 2.sub-aerial stem modifications aerial stem modifications
Can cactus plants be infected by cold places?
Yes, cactus plants can be infected by cold places. The two main types of cactus plants are the desert cactus and the jungle cactus. The desert cactus handles higher heat and light levels and lower moisture levels. The jungle cactus handles higher heat and humidity levels and lower light levels.But neither type of cactus handles cold, damp temperatures. Chilling temperatures makes a cactus susceptible to all sorts of fungal problems, such as basal stem rot. The cactus' tissue ends up softening and blackening. It has to be dried out or removed.
