This sounds like one of those grafted things where the red ball cactus is grafted on top of a green one as the red one contains no chlorophyll so cannot support itself and relies on the green one .Just treat it like any other cactus water sparingly and keep the air round it dry.
In cactus leaves are absent. Chlorophyll are found in trunk mainly.
light refraction of the presence of chlorophyll.
cactus have a hollow stem. it is where they store water and food for survival
Yes there are photosynthetic stems. Green stems carry out photosynthesis. Example: cactus
A cactus makes food through the process of photosynthesis, like any other plant. The difference between a cactus making food from another plant is that cactus have their leaves reduced to spines, therefore, their stem contains chlorophyll and photosynthesis takes place through the stem.
The 'spines' of a cactus attach directly to the stem of the plant.
A cactus stores water in its stem.
Water is stored in tissue in the stem of the cactus.
The stem of a cactus is able to store water during rainy periods for use during a drought.
Water, dissolved nutrients, and byproductsof photosynthesis are stored in the cactus stem. The water and the dissolved nutrients are sent up into the stem from the cactus plant's roots. They're held in the stem until they can be used in the photosynthetic interaction with sunlight. From that interaction are made the energizing carbohydrates, starches and sugars that the cactus needs for such activities as flowering, fruiting, growing, reproducing, and responding to stresses and stressors.
They come in different colors- red, yellow, and green. They are fairly round shaped. They usually contain a leaf by the stem. They have a stem.
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.
