Is there an incomplete leaf in Tibet?

Incomplete leaves, in the three-part structure of leaves, petioles and supporting leaves, the leaves that lack one or two parts are called incomplete leaves. There are fewer leafless leaves, such as the acacia tree in Taiwan, where the leaves are completely degraded, and the petioles are flattened and can carry out photosynthesis, which is called petioles. A complete leaf should have three parts: the leaf, the petiole and the leaf body, which are called complete leaves, such as the leaves of pears, peaches, peas, yueji and other plants.

Conception. Complete leaves.

In the three-part structure of leaves, petioles and supporting leaves, the leaves that lack one or two parts are called incomplete leaves.

Example. Such as tea, cabbage, cloves and other plant leaves. If there is no leaf, or there is no leaf and petiole, it is called an incomplete leaf.

The leaves of plants such as cabbage, tea, and cloves are called incomplete leaves.

Only the leaf sheath type.

For example, the leaves of the Poaceae and Orchidaceae of monocots do not have petioles and pedicles, but only leaf sheaths.

Leafless type. The most common leaves without supporting leaves, such as the leaves of privet, cloves, forsythia, tea, cabbage, sweet potato, etc.; At the same time, the leaves without supporting leaves and petioles, such as lettuce, endive, caryophyllus, tobacco, etc. (also known as sessile leaves);

Lettuce. Mosaic lettuce (leaf lettuce).

Bladeless type. There are fewer leafless leaves, such as the acacia tree in Taiwan, where the leaves are completely degraded, and the petioles are flattened and can carry out photosynthesis, which is called petioles.

Counterexample. A complete leaf should have three parts: the leaf, the petiole and the leaf body, which are called complete leaves, such as the leaves of pears, peaches, peas, yueji and other plants.

There should be, because there are a lot of species in the battlefield that are not special. Well, not exactly what about the leaf, he is missing some in the part of the leaf. I feel like there should be.

If the leaves of a plant have leaves, petioles and petioles, they are called complete leaves, and if they do not have leaves, or if they do not have leaves and petioles, they are called incomplete leaves.

There is indeed a place called Kaba Tibetan Land in the Ruola grassland, with herds of cattle and sheep, green grass and beautiful scenery.

The leaves have three parts: leaves, petioles and supporting leaves, such as the leaves of pears, peaches, peas, yueji and other plants.

Incomplete leaves. Some leaves have only one or two parts, which are called incomplete leaves, such as the leaves of tea, bailai, cloves and other plants.

There will be no less nameless than there will be no one who knows the name.

Tea tree belongs to incomplete leaves, with petioles and leaves, but no supporting leaves, on the branches for a single leaf alternate, the state of growth varies according to the variety, there are erect, semi-erect, horizontal, drooping four kinds. On the same branch, the upper new leaves are more erect, and the leaves gradually flatten from top to bottom as the leaf age increases.

The petioles are centimeter long, semicircular, or rectangular paraxially. The petiole vascular bundles are called leaf traces, and their shape varies depending on the variety, and there are round, oval, hemispherical, etc. The length of the petioles, the color, the grooves and the shape of the leaf traces are one of the bases for the classification of tea plants.

The leaf surface is leathery, shiny, smooth, and raised. The curvature of the leaf surface is folded at a certain angle along the main vein, some are flattened, and a few varieties also have the back of the leaf to be flipped up. The back of the leaf is leathery, rough, and porous.

The stomata are the channels for gas exchange inside and outside the tea plant, and the number of stomata in large-leaved species is small and large, and the number of stomata in small-leaved species is more and smaller.

Tea tree leaves can be divided into scales, fish leaves, and true leaves.

The scales are hard, yellow-green or brown in color, with hairs and resin on the surface, and the surface cells are thick tissues, which have the functions of protecting young shoots and reducing transpiration and water loss. The scales are tile-like, and the annual vegetative buds generally have 1 3 scales, and the overwintering buds usually have 3 5 scales, and when the bud body expands and develops, the scales will fall off quickly.
