Do cacti have leaves, and will they grow leaves?
The cactus is a plant known to every household; it is both beautiful and able to purify the air. Next, let us take a look at whether cacti grow leaves.
Do cacti have leaves? The answer is: yes, but in order to adapt to the dry, rain-scarce desert environment, over the long ages the cactus constantly changed its form, and its leaves gradually disappeared, turning into fleshy spines or dense downy hairs, reducing water transpiration to the greatest extent. The cactus's leaves have degenerated, and it relies on its stem to produce nutrients, while the stem is green and performs the function of leaves, carrying out photosynthesis in sunlight. So the cactus's spines evolved from leaves. And the cactus's spines can absorb nutrients from the air.
What are the uses of the cactus?
1. Acute mastitis: Take an appropriate amount of fresh cactus or cactus ball, remove the spines and fine hairs on the surface, wash clean, and mash. When using, apply the cactus paste thickly to the red and swollen area of the breast, cover with gauze, and secure with adhesive tape. Change the dressing several times a day, keeping it moist.
2. Purulent otitis media: Take equal parts of cactus (peeled) and dandelion, wash clean, mash, and squeeze out the juice, then drip it into the ear, 24 drops each time, 2-3 times a day. This formula has good effects for patients with purulent otitis media, generally requiring about 35 days of medication, and has good antibacterial, anti-inflammatory, heat-clearing and detoxifying effects.
3. Epidemic parotitis: Mash an appropriate amount of cactus (peeled, washed clean), add a little duck egg white, mix thoroughly and evenly, put into a bottle, seal, and set aside. During treatment, spread the medicinal paste onto thick sterilized gauze, and choose the size of the medicated area according to the extent of swelling in the patient's parotid area. For unilateral onset, apply to one side; for bilateral onset, apply to both sides, changing the dressing once a day. For those who use the medicine promptly, it generally heals after 2 applications.
Can cacti carry out photosynthesis?
Of course they can. The cactus's stem turns green, contains chloroplasts inside, and its epidermis is cutinized, so it can carry out photosynthesis. The cactus's photosynthesis does not take place during the day, but at night when evaporation and temperature are relatively lower, which can minimize water loss. The cactus's leaves have become smaller, but its sharp needle-like leaves spread all over its body, and as a result this actually enhances photosynthesis.
How do cacti store water?
Primitive cacti of course do not need to store water, but cacti in the desert are a small "reservoir" for storing water. The cactus's roots extend very far and cover a large area, and during the rainy season they also send out many new roots to absorb as much water as possible; the cactus's stem is fleshy tissue, and when there is more water in the body it becomes thick and plump, with a waxy layer on the surface, and the waxy protective layer can prevent water loss. When the dry season arrives, its roots wither and fall off to maintain the water supply. As water content decreases, the stem also shrinks, its own growth slows, and it enters a dormant period.
