In some parts of southern Africa, it is common to see grayish-black "pebbles" in the rocky thickets. Sometimes, these "pebbles" are filled with beautiful flowers. It turned out that it was not a pebble, but a plant!

This plant grows in stone bushes with only a few fat leaves that land on the ground. Its leaves resemble pebbles in both color and shape, and people have given it the name "Raw Stone Flower", which means a flower that grows on a stone.

Raw stone flowers are similar in shape and color to pebbles, which can fool the eyes of herbivores and prevent them from being eaten! This phenomenon of plants resembling the environment is called plant mimicry by scientists. The mimicry of plants is similar to that of animals, and they can protect themselves.

In the Himalayan region of our country, there is a kind of "eye grass". It looks like a cobra with its head sticking out its tongue! It often makes some small herbivores afraid to eat it, which can be regarded as a wonderful plant mimicry phenomenon.

It starts out yellow, then changes to flesh, pink-orange, and finally green. Nugget: One of the varieties of longevity flowers that change color.

Seasonal flowers: rich and varied. Garland <>

It belongs to one of the plants that changes the most color.

1. Five-color plum

Five-color plum, also known as Ma Yingdan, belongs to the erect or vine shrub, because there are often a variety of color changes in a cluster of inflorescences, and the color change of the plant will vary greatly according to the different varieties.

2. Flower candles

There are two kinds of anthurium, anthurium and pink palm, in which the anthurium is yellow at first, and then changes to flesh color, pink-orange in turn, and the flowers of the plant bloom from bottom to top, so the inflorescence sometimes shows a variety of colors, and when the anthurium is about to wither, the inflorescence will slowly turn green.

5, Garland

Garland is the most discolored plant, and the variation of different parts of the same flower varies, and the flowers are green at the beginning of the flower, and the middle of the petals gradually turns yellow the next day, and the edges of the petals are bright red.

Because there is chlorophyll in the leaves of the cherry blossom plant, the plant turns green.

Plants are one of the main forms of life, including trees, shrubs, vines, grasses, ferns, green algae, lichens and other well-known organisms. 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.

Photosynthesis: Plants have the ability to photosynthesize - that is, it can use light energy and chlorophyll that animals do not have, use water, inorganic salts and carbon dioxide for photosynthesis, release oxygen, and produce glucose - energy-rich substances for the use of plants.

The causes of plant discoloration include the absorption and reflection of light by some pigments in chloroplasts, light and temperature conditions, and pH value.

1. Light absorption and reflection by some pigments in chloroplasts.

There are chloroplasts in the leaf cells of plants, and chlorophyll, carotenoids and other pigments in chloroplasts can absorb and reflect part of the visible light in sunlight for photosynthesis.

Chlorophyll mainly absorbs blue-violet light and red light, and almost does not absorb green light. Carotenoids mainly absorb blue-violet light, reflecting yellow, orange, or orange-red light.

2. Light and temperature conditions.

The young leaves contain less chlorophyll, and the other pigments are more dominant, and the leaves will show other colors. As the leaves mature and the chlorophyll content increases, the green color deepens. Light and temperature regulate the synthesis and decomposition of chlorophyll and carotenoids in the leaves at the same time.

3. PH value.

In the vacuole of plants, there are also a variety of pigments, different pigments will show different colors under the same pH conditions, and the same pigment will have different colors under different pH conditions.

Plants whose leaves change color:

1. Oil point lily.

The leaves are withered and unsightly spots, but they are very attractive, the leaves are very bright, and there are large bulbs on the rhizomes. I like the leopard spots on its page the most, and if the weather gets a little colder, its leaves will turn lemon yellow, which is even more beautiful.

2. Zhujiao. There are actually a lot of varieties of bananas, dwarf varieties are very suitable for potted maintenance, raised on the balcony, if the temperature drops suddenly, plus a little cold rain, its green leaves will slowly turn red, very wonderful, raised banana to know wonderful.

3. Amaranth.

Amaranth is a relatively niche herbaceous foliage plant, its leaves also change with temperature, and the colors vary from season to season, including green, reddish-brown, peach, and yellow.

4. Rainbow pepper grass.

It is a plant of the same genus as the round-leaved pepper grass (jasper), which has white markings on its leaves, and although it is shade-tolerant, it looks best when kept in a bright place. Especially when the weather gets colder, the leaves will slowly turn peach, with colorful reds and yellow-green contrasting with each other.
