[does the cactus have leaves] can the cactus grow leaves

Cactus is a well-known plant, which is beautiful and can purify the air. next, let's see if the cactus can grow leaves.

Does the cactus have leaves? The answer is: yes, but in order to adapt to the dry and rainless desert environment, the cactus has been changing its shape over the long years, and the leaves have gradually disappeared, turning into root spines or dense hairs, minimizing water transpiration. The leaves of the cactus are degraded and are nourished by the stems, while the stems are green, performing the function of leaves and photosynthesis in the sun. So the thorns of cactus are changed from leaves. The thorns of the cactus can absorb nutrients from the air.

What are the uses of cactus?

1. Acute mastitis: take the right amount of fresh cactus or cactus, remove the thorns and villi on the surface, wash and mash. When in use, apply the cactus confusedly to the red and swollen area of the breast ☆ forbidden ☆ room, covered with gauze and fixed with adhesive tape. Change the dressing several times a day to keep it moist.

2, suppurative otitis media: cactus (peeled), dandelion and other portions, washed and mashed to take juice, drop into the ear, 24 drops each time, 2-3 times a day. The prescription has a good effect on patients with suppurative otitis media, generally takes about 35 days, and has a good effect of antibacterial, anti-inflammatory, heat-clearing and detoxification.

3. Mumps: mash the cactus (peeled and washed), add a little duck egg white, mix well, bottle and seal. During the treatment, the drug paste was spread on a thick sterilized gauze, and the size of the patch area was chosen according to the swelling area of the patient's parotid gland. Unilateral disease was applied on one side, bilateral disease on both sides, and dressing changed once a day. If the medicine is used in time, it will generally be cured twice.

Can cactus carry out photosynthesis?

Of course. The stem of the cactus turns green and contains chloroplasts and keratinized epidermis, which can be used for photosynthesis. The photosynthesis of cactus is not carried out during the day, but at night when evaporation and temperature are relatively low, which can minimize water loss. The leaves of the cactus become smaller, but its sharp needles spread all over the body, resulting in increased photosynthesis.

How does the cactus store water?

Of course, the primitive cactus does not need to store water, but the cactus in the desert is a small "reservoir" of water storage. The root of the cactus extends far and covers a large area, and many new roots are sent out in the rainy season to absorb as much water as possible; the stem of the cactus is fleshy tissue, which becomes thick and thick when there is too much water in the body, and there is a layer of wax on the surface. Waxy protective layer can avoid water loss. When the dry season comes, its roots wither and fall off to maintain water supply. With the decrease of water content, the stem will contract, slow down its own growth and enter the dormant period.
