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
In cactus leaves are absent. Chlorophyll are found in trunk mainly.
The 'spines' of a cactus attach directly to the stem of the plant.
Water is stored in tissue in the stem of the cactus.
A cactus stores water in its stem.
The spikes protect the stem of the cactus plant. The reason is the stem's responsibility for moving, processing and storing water and watery products and solutions. The stem also is responsible for carrying out the photosynthetic interaction with sunlight to make energizing, life sustaining starches and sugars.The spikes protect the overall stem, and specific stem parts. For example, the stem is the location of the breathing pores, or stomata. The stomata are the points at which gases within the cactus are exchanged for atmospheric gases. The stem also is the location of the growth buds from which flowers, fruits and seeds form.
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.
A cactus stores most of its water in its stem or body
A cactus that stores water in its stem is called a stem succulent. The stem has tissues that are capable storing large quantities of water. The stem also has a thick waterproof epidermis covered by a waxy cuticle that prevents loss of water due by evaporation. Examples of stem succulents - Cardon Cactus, Organ Pipe Cactus, Saguaro Cactus
Carbon dioxide is the gas needed for photosynthesis that enters through the stomata of the cactus stem.
A cactus can store water in its fleshy stem and this enables it to survive periods of drought.
