Plants | Gymnosperms

Mango, berry, litchi, banana, jackfruit, guava, plum etc. are very familiar to us. We know these as plants of fruit. Beans, potatoes and brinjal etc are also very familiar to us. We know them as vegetable plants. Sugarcane, mustard and sesame are known as oil-producing plants.

The cell wall of plants (which animals do not have) is made up of cellulose. That is, cellulose is one of the main constituents of plants. How is cellulose? Cellulose is a solid organic chemical. The color is white. They have nothing to taste or smell. Does not dissolve in water. The molecular mass of this substance can range from 2 lakhs to a few lakhs. Like fiber, this substance is much harder. No color can be obtained by applying iodine solution. Where is the amount of cellulose? Cotton contains a lot of cellulose, about 94%. Linen is found in 90% and wood in 80%. Grass contains 30-40% cellulose. Soils rich in organic matter contain 40-60% cellulose. Can people digest cellulose? The answer is no, can't. This is because cellulose, the main enzyme f...
