Why is grass green? 40

The green color of the plant is the result of photosynthesis. The reason why plants are green is because of the presence of light. The color of any object is the color of the part of light it reflects.

The reason why plants are green is that they rely on the pigment in their cells that can capture energy, called [chlorophyll], (in terms of chemical structure, it is composed of 4 porphyrin rings connected together, **complexed with a magnesium atom), and the two parts constitute a complete chlorophyll molecule. Chlorophyll is a general term for this type of photosynthetic pigment, and according to the subtle differences in their chemical structure, chlorophyll is divided into three types, namely chlorophyll a, chlorophyll b and chlorophyll c. Among them, chlorophyll a is the main photosynthetic pigment, which is present in all photosynthetic oxygenated plants, and the other two are auxiliary pigments, which exist in different plant phyla.

In addition to chlorophyll, there are other types of photosynthetic pigments such as carotene, phycobilin, etc., which are also photosynthesized in plants. Auxiliary pigments, the color of the plant depends on the combination of several pigments. In all photosynthetically oxygen-emitting organisms, there is chlorophyll a, chlorophyll a has two absorption peaks of sunlight, which are the blue zone near 440 nm and the red zone near 680 nm, one is located in the blue region, the other is located in the violet region, and the green light between 50 0 600 nm absorbs very little, so the plants we see are basically green.

Because green is the middle of the solar spectrum, this makes plants that rely 100% on the sun's energy to convert other energy, and then use other energy, so that they can absorb the sun's energy to the maximum. And to achieve this purpose, it is like picking something, you must balance both sides, so that you can pick the most. In the same way, if a plant wants to absorb the most, it also has to pick the middle spectrum of the sun, and the middle of the spectrum is green, so the plant has to make itself green in order to absorb the most and balance the solar spectrum; in order to make the most of the natural conditions of sunlight; in order to be satisfied to the greatest extent.

So the grass is green, the trees are green, and the vegetation of the earth is overwhelmed and covered by green.

It's not necessarily green, it's green mainly because most of the green leaves contain chlorophyll, and in autumn they turn yellow because the temperature gets lower, and chlorophyll can't be synthesized and can't participate in photosynthesis.

Because the grass reflects green light, it absorbs all light except green light.

Chloroplasts absorb light of other colors and reflect green light.

So the grass we see is green.

Autotrophic plants are produced by the ecosystem, mainly photosynthesizing to produce organic matter, so there must be chlorophyll, so it is seen to be green.

Because grass has chlorophyll inside its cells.

Because there is chlorophyll in the grass, the color of the grass is green, and the grass will look very green when exposed to sunlight.

Because grass contains a lot of cyanin, it is green when combined with sunlight.

Grass is not only green but also white, for example, there are various colors of flowers.

Repeat what I said; "The grass is green, in fact, the grass is red and green", what color is the grass?

The point is repetition!

The grass in spring is green; The grass is emerald green in summer; The grass in autumn is withered and yellow.

The reason why grass is green is because the leaves contain chlorophyll, and the primary leaves have less chlorophyll, so the color is light green, and chlorophyll can use water, air and sunlight to produce nutrients that plants need.

The color of the grass is green because the leaves contain chlorophyll, and the color of chlorophyll is also green, among which the primary leaves have less chlorophyll and the leaf color is light green, while the mature leaves have more orange and sweet potatoes and the leaf color is dark green.

Grass likes to grow in a sunny environment, and only when exposed to sunlight will the chlorophyll in the leaves play a role, making the leaves more colorful, so in the process of cultivating grass, it needs to be placed in a brightly lit place.

Grass does not require much soil to grow, can grow robustly in any soil, and is very tenacious, but in order to make grass grow round and thicker, it needs to be provided with highly permeable soil with rich organic matter.

Grass needs to be fertilized, but the plant's demand for fertilizer is small, every 1-2 months to apply farmhouse fertilizer, cut hands to avoid too much fertilizer, otherwise the grass will grow wildly, especially in the vegetable field, will cause crops to be infected with pests and diseases.
