Green plants are those which include all organisms commonly known as green algae and land plants, including live-words, mosses, ferns and other non-seed plants and seed plants. Green plants are termed as a broad assemblage of photosynthetic organisms that all contain chlorophylls a and b, store their photosynthetic products as starch inside the double membrane-bounded chloroplasts in which it is produced and have cell walls made of cellulose.
In this group are several thousand species of what is classically considered green algae plus several hundred thousand land plants.
Green plants make their own food:
The process by which plants make food is called photosynthesis. This process begins with sunlight, and when this sunlight is inhibited, food production for plants also stops. Green plants are the only organisms in the world that make their own food, this process is called photosynthesis. It begins when the sunlight artificial light can power it to strikes the plants leaves. Inside the plant cell are parts called chloroplasts which contain a green pigment called chlorophyll. Chlorophyll is what gives the leave its green color. It absorbs energy from the sunlight which a plant uses to make food. The plants are able to make their own food with the use of the sun’s energy. As the sunlight shines, the layer of cells in the leaf of the plant traps the light energy and captured it. A process in the chloroplast uses water and changes the light energy into a kind of a so-called chemical energy. The water that was used earlier in changing light energy to chemical one is separated then by the chlorophyll into hydrogen and oxygen. The newly transformed chemical energy is stored in the chloroplast. The chloroplast is now ready to use this chemical energy to make food for the plant. The green plants are called the producer and are the main source for humans and animals.
Facts about plants:
- 85% of plant life is found in the ocean.
- Lots of plants are used as dyes. You can color cloth with stewed onion skin, tea bags or walnut juice. One of the oldest blue dyes comes from a plant called ‘woad’ that has been used since Neolithic times – more than 6,000 years ago.
- Brazil is named after a tree.
- Stress relief can be achieved with chemicals in the freshly-cut grass, according to scientists.
- 70,000 plant species are utilized for medicine.
- 2009 is the year scientists discovered a plant in the Philippines that is capable of devouring rats.
- More than 20 percent of the world oxygen is produced in the Amazon Rainforest.
- Dandelion is completely edible, from the petals to the roots.
- The first certified botanical garden was founded by Pope Nicholas III in the Vatican City in 1278 AD.
- Trees are the longest-living organisms on earth.
- There is a plant in Australia known as the “Suicide Plant” because the effect of its sting can last for years, and its pain is so unbearable that people have killed themselves after touching it.
- Plants may be deaf, but they can feel, see, smell and remember, according to plant biologist Daniel Chamovitz.
- 34m is the height of the world’s tallest recorded basil plant.
