PARTS OF A PLANT CELL
Are you familiar with cells? What are cells? Cells are the fundamental unit of the structure of life. It has the responsibility of initiating, regulating and coordinating all of the life-sustaining chemical reactions. For them to do all of these functions, cells are made up of smaller membrane-bound parts. In this article, it will explain you further its parts and functions.
There are three types of cells. They are the human cell, plants cell and the animal cell. We will just focus on the parts of a plant cell.
Parts Of A Plant Cell
Chloroplasts – these are the chlorophyll-bearing plastids. These plastids are cellular in structure which generally holds the pigments. The plants have the other kinds of plastids besides the chloroplasts. Example of this is the chromo plastid which contains the two types of pigments: the carotene and the xanthophylls.
Cellulose – this is a carbohydrate with long chain of the sugars that are linked together. Most of the animals cannot digest cellulose when human beings eat the vegetable and fruits, the cellulose part passes out the food tube without being digested.
Cell wall – it’s made of the combination of the fat, protein, and the carbohydrate molecules. The cell wall is rigid.
Vacuoles – vacuoles are large in the mature plant cells; however they are fewer and smaller in the young plant cells. This water-filled sac within the cytoplasm stores the food, the waste products and the other materials.
Cell membrane – it consists of the double layer of the fats and the proteins. It is elastic because of the structure of protein molecules which are relatively long molecules and they can easily be folded. The cell membrane is differentially permeable. It permits some substances to pass through readily, others slowly and the others not at all.
Nucleus – all of the plant cells contain the nucleus. It directs all of the activities of the cells and that includes the reproduction.
Endoplasmic reticulum – this network of passages carries the materials from one part of the cell to another.
Cytoplasm – granula is found in the cytoplasm. It consists of the protein layers with fat and the pigment molecules between them. The liquid and membranes inside the chloroplast contain the special protein molecules, the photo synthetic enzymes, because they promote the chemical reactions of the photosynthesis.
So those are the parts of a plant cell and its functions. Now you know the already about it.
