because as we all know, cactus' do not have leafs, and for mot cactus' that live in the desert or suburban areas there is little rain. so the stem of the cactus does the same job as the leaf does on a normal plant and performs photosynthesis.
1.under ground stem modifications 2.sub-aerial stem modifications aerial stem modifications
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.
The main function of a bark in a woody stem includes an outer protective layer and an inner layer of living phloem which transports food through the stem
The stalk that joins the leaf blade to the stem is called the petiole. Its main function is to support the leaf and provide a pathway for nutrients to move between the leaf and the rest of the plant.
Reduced leaf surface area to minimize water loss through transpiration. Stem modifications, such as succulence, to store water and perform photosynthesis. Waxy cuticle to prevent water loss and spines for defense against herbivores.
Awnser The function of a stem is to pass water to the roots
holds the leaf in connects to the plantpetiole is the thin green sructure that connects the main stem to a leaf.its also called MESOPODIUM.its main function is to direct the leaf from the branch so that it could get sufficient sunlight to perform photosynthesis

Thorns are leaf modifications in opuntia (a type of cactus) and a stem modification in bougainvillea. So it depends on the type of plant.

The function of the epidermis in the stem is to protect the underlying tissues.

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.
cactus have a hollow stem. it is where they store water and food for survival

A graph and stem is different to a leaf plot because in a leaf plot, there is a stem and leaf in a plot, while in a graph and stem, there is a leaf and stem in a graph.
