Chlorophyll gives cactus stems their green color. A cactus has chlorophyll because of the stem's photosynthetic interaction with sunlight to make cactus foods. In many other plants, photosynthesis takes place in the leaves. But cactus needles don't offer a large enough surface for photosynthesis to take place or for photosynthetic byproducts to be stored. Instead, needles have reduced surface areas to stop surface evaporation of moisture. So photosynthesis instead must take place within the larger surface area of the stem.
Saguaro plants have green stems.
Cactuses belong to the plant group known as Angiosperms, specifically within the order Caryophyllales. They are further classified in the family Cactaceae, which includes a wide variety of species adapted to arid environments. Cactuses are characterized by their unique structures, such as thick, fleshy stems and spines instead of leaves, which help them conserve water.
herbaceous
The duration of Cactuses is 1.55 hours.
Yes. As you can see, herbaceous stems are soft and green while woody stems are thick, hard and woody. Stems can be of several sorts, herbaceous and woody. The herbaceous stems are green and fairly bendable. The woody stems as their name implies, are covered by bark. The herbaceous stem has more pith for its size. The cambium which causes woody stems to get bigger in width is not as active in the herbaceous stems. Most herbaceous plants are annuals or planted yearly. The herbaceous stem has little notches where leaves develop. Woody stems have scars where twigs and fruit have dropped off and little openings for transpiration.

"Cacti" is the plural form of "cactus," which refers to a type of plant known for its thick, fleshy stems and spines. Cacti are adapted to arid environments and are able to store water in their stems to survive in dry conditions.
Yes there are photosynthetic stems. Green stems carry out photosynthesis. Example: cactus
Radishes are sometimes red and can be found in other colors. Their stems are always green.
Soft stem are green and have chloroplasts.Woody stems do not have.
Okra ( Abelmoscus esculentus) has a green stem, but it is not soft.
It depends on the plant, the most popular thorn plants are cactuses and roses, i hope this helps
