What are the common monocots and dicots 5

The most common monocots are wheat, rice, corn, and canna.

Magnolia, etc. The most common dicots are soybeans, peanuts, apples, chrysanthemums, cotton, sunflowers, etc.

The fundamental difference between them is the development of two ** leaves or one ** leaf in the embryo of the seed, two are called dicots, and one is called monocots. These two types of plants are relatively easy to distinguish because there are some distinct morphological differences between them. The root system of dicots, which is basically straight.

The taproot is well developed; Quite a few are woody plants.

The stem can be thickened continuously; The leaf veins are reticulated; The number of sepals and petals in the flower is 5 or 4, and if the petals are combined, there are 5 or 4 lobes. The root system of monocots is basically fibrous root system, and the taproot is underdeveloped; Mainly herbaceous plants.

There are few woody plants, and the stems usually do not thicken from year to year; The leaf veins are parallel veins, and the number of sepals and petals in the flower is usually 3, or a multiple of 3. The above differences make it easier to distinguish between monocots and dicots.

Throughout angiosperms.

In addition to almost all trees, there are many fruits, melons, fibers, oil plants, and many vegetables; Whereas, monocots have a large number of food plants, such as rice, corn, barley, wheat, sorghum, etc.

Dicotyledons:

Monocots:

Monocots: corn, sorghum, rice, wheat, sagebrush, orchid, etc.

Dicotyledons: Most fruits and vegetables (cucumbers, winter melons, celery......Most of the flowers (Yueji, Osmanthus, ......）

Common monocots: wheat, corn, sorghum, sagebrush (grass).

Common monocots: soybeans, peanuts, cotton, purslane (vegetables).

1. The epidermis is different

Dicotyledon.

Stem primary structure: epidermal cells are mostly rectangular or square, and there is no obvious distinction between long cells and short cells;

Monocotyledons.

Stem primary structure: the epidermis is composed of long and short cells, the former keratinized, the latter plugged and silicified;

2. The vascular bundles are different.

The stem vascular bundles of dicots are mostly infinitely external tough, and there is a cambium between the primary xylem and the primary phloem, so it is also called the cambium in the bundle.

The vascular bundles of monocot rhizomes are usually of a finite external toughness type, and their arrangement is arranged in two rounds.

3. The differentiation of cortex and medulla is different.

Dicotyledons: have a pronounced differentiation of the cortex and the pith, which is organized by thick horns (sometimes with chloroplasts.

and parenchyma composition;

Monocots: without obvious cortex and pith distinction, collectively referred to as basic tissues, composed of thick-walled and parenchyma tissues, and sometimes with assimilated tissues.

The vast majority of monocots are herbaceous, and a very small number are woody, and the common ones are rice, wheat, corn, and millet, sugarcane, barley, asparagus, bamboo shoots, green onions, garlic, leeks, yams, bananas, pineapples, lintou, orchids, rich bamboo, narcissus, lilies, tulips, iris, king coconut, palmetto, yellow coconut.

Dicotyledons are two cotyledons in its seeds, and the common dicots are oleander, white orchid, lotus magnolia, etcWinter melon, watermelon, bitter gourd, radish, cabbage, camellia, saffron, iron holly, cotton, choy sum, bunch of red, kale and other plants.

Plant Classification:

Plants can be divided into seed plants, algae plants, bryophytes, ferns, etc., and it is estimated that there are about 450,000 species in existence. Most of the energy of green plants is obtained from sunlight through photosynthesis, and temperature, humidity, light, and fresh water are the basic needs of plants for survival.

Angiosperms have six major organs: roots, stems, leaves, flowers, fruits, and seeds. Green plants have the ability to photosynthesize - with the help of light energy and chlorophyll, under the catalysis of enzymes, they use water, inorganic salts and carbon dioxide for photosynthesis, release oxygen, and produce organic matter such as glucose for plant use.

1. Single-leaved plants: palm, coconut, betel nut, konjac, taro, calla lily, monstera, shandan, onion, garlic, leek, tulip, hosta, baiji, gastrodia, Jianlan, daylily (goldenrod), ground balm, etc.

2. Double-leaved plants: laughing flowers, white orchids, tulipwood, cabbage, radishes, cabbage, mustard greens, watercress, pumpkin, winter melon, watermelon, cucumber, bitter gourd, loofah, cotton, hemp, safflower, hollyhock, castor, cassava, rubber tree, black tree, tung oil, wood oil tree, etc.

Dicotyledons (also known as true dicots) and monocots are the two main plant taxa. Their name indicates their seed structure in the endosperm.

Dicotyledon is a class of seed plants whose endosperm contains two cotyledons (seed sheaths). Here are some examples of common dicots:

1.Fabaceae: Includes legumes (e.g., soybeans, peanuts) and broad beans.

2.Rosaceae: including roses, apples, cherries, and strawberries.

3.Liliaceae: including lilies, irises, etc.

4.Asteraceae: including chrysanthemums, sunflowers, etc.

5.Cruciferous plants (brassicaceae): including mustard greens, kale, etc.

The endosperm of monocotyledon contains only one cotyledon. Here are some common examples of monocots:

1.Poaceae: including rice, wheat, corn, etc.

2.Orchidaceae: including orchids, etc.

3.Palm plants (arecaceae): including palm trees, etc.

4.Liliaceae: Paulownia irise, etc.

5.Araceae: including taro plants, etc.

These are just some examples of the two groups of plants, and there is actually a wide range of dicot and monocot species that exist. They all have some characteristics and differences in morphology, growth habits, and ecological roles.

Our common twin leaf plants are peanuts, soybeans, apple trees, peach trees, watermelons, sunflowers, poplars, willows, paulownia trees, black locusts, hibiscus flowers, etc.

Common monocots include corn, sorghum, wheat, eggplant, rice, millet, foxtail, gladiolus, irise, etc.

Monocots: the leaves are parallel or arcuate; cotyledons monolithic; The number of flowers is usually 3, and the calyx and corolla are very similar and difficult to distinguish;

Anatomically: the vascular bundles in the stem are scattered and do not arrange in loops. If it is arranged in a circle, it is arranged in two or more circles, and there is no cambium, so it cannot produce secondary xylem and secondary phloem, and it belongs to finite vascular bundles (closed vascular bundles), so the stems of monocots cannot be arbitrarily thickened; The stomata on the leaves of monocots are arranged in a relatively regular manner, mostly arranged in rows; Pollen of monocots with a single germination pore.

Such as wheat, onions, rice, etc.

Dicotyledons: straight roots; The leaves have reticular veins; cotyledons two; The flower base is usually 5 or 4, and the morphology of the calyx and corolla is also very different; Anatomically: the vascular bundles in the stem are arranged in a ring, that is, arranged in a circle, and there is a cambium layer, which can produce secondary xylem and secondary phloem, which belongs to the infinite vascular bundles (open vascular bundles), so that the stem of the dicot can continue to thicken;

The stomata on the leaves of dicots are irregularly arranged and mostly scattered; The pollen of dicots has 3 germination pores.

Such as apple trees, poplars, elms, acacias, cotton, sunflowers, etc.
