The stomata on cactus plant are contained in the skin of the cactus stem. The cacti which are considered more primitive, such as Peireskia and Opuntia, also have stomata in their leaves. The more highly desert adapted cacti have no leaves so they photosynthesise through their skins. Often the stomata are heavily protected by physical adaptations such as waxes or pits in the skin. They also display "behavoural" adaptations such as opening only at night to reduce water loss even further.

Yes cactus plant has a sunken stomata .

Why does a cactus has a few stomata?

I think because in a desert, the cactus doesn't find much water. So, to save water it does not expel much water out of itself, and as stomata is responsible for expelling water of the plant, the cactus has less stomata

Which one has more stomata cactus or water lily?

Water lilies will have less. Water plants have stomata on the sides exposed to air. Or if totally submerged, there are no stomata present. A cactus is covered with stomata but not as much as average plants.

Why does cactus plant has small leaves and few stomata?

To reduce water loss as much as possible.

How many stomata does a cactus have?

Very few by comparison to other plants. In most cacti the leaves have been modified to form spines or thorns in order to reduce transpiration (and for protection). Because the bulk of stomata are found on leaves there will be fewer on a cactus plant as it does not have leaves.

What are three adaptations of a cactus?

The leaves of a cactus have been reduced to spines to deter herbivory. The stems are fleshy and photosynthetic. The stomata are sunken into the surface of the leaf to increase the boundary layer.

Does the cactus have a stomata?

Yes. The cacti may practice a delayed form of photosynthesis because they must close their stomata in the daytime but they, like all other plants, must take in carbon dioxide and release oxygen and water through those stomata.

How do cactus respire as it do not have stomata?

In plants respiraation takes place in the cytoplasm (glycolysis) and mitochondria (Kreb's cycle). The Cactus have both these structures, therefore, respiration in Cactus takes place like other plants. For gaseous exchange these might have developed own adaptations.

Can cactus plants survive without stomata?

No, a cactus can't survive without stomata. Each stoma is a breathing pore whose opening is controlled on both sides by guard cells. The pores are the points of gas exchange between the cactus and the outside world. For example, the pores release oxygen, for the purification of the environment; and take in carbon dioxide, for the plant's all important photosynthetic interaction with sunlight. So the stomata control what gets into and out of the plant's stem. The point therefore is to minimize inside water losses and maximize what's needed from the outside for making energizing photosynthetic products.

How does a cactus breathe?

A cactus breathes through its stomata. These are little holes on the flesh or skin of the cactus. Through it's thorns Cactii breathe through pores in their skin called stomates. These are generally closed during the heat of day to retain moisture and opened during the night to allow respiration to occur. Photosynthesis

How do plants without leaves absorb carbon dioxide?

Many plants without conventional looking leaves (such as cactus) have evolved to have stomata (the pores through which carbon dioxide enters the plant) on their stems or on other surfaces. (Stomata are typically only found on the underside of leaves.)

Which part of the cactus do the spikes protect?

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.

What is stomata responsible for?

The stomata is used for gas exchange. Carbon dioxide enters into the stomata. Oxygen exits through the stomata.
