Answer:
The Cell is the basic structural and functional unit of all living organisms. Each cell has the capacity to perform basic functions that are characteristics of all living forms
Step-by-step explanation:
- The cell has the capacity to replicate itself hence it is known as the building block of life. Each and every cell contains a fluid called cytoplasm.
- The Cytoplasm is enclosed by a membrane called plasma membrane or cell membrane. Inside cytoplasm there are certain specific components in it which are known as cell organelles.
- Each cell organelle performs special functions, such as making new material in the cell clearing up waste material from the cell and so on.Because of these organelles, a cell is able to live and perform all its functions.
- All the cells have the same organelles, no matter what their function is or what organisms they are found in. It is known that a single cell may constitute a whole organism like in amoeba,
There are two types of cells:
- The outer cell membrane, cell wall in plants, inside nucleus which is separated by a well nuclear membrane in the eukaryotic cell nucleus and cell membrane separated by a fluid called cytoplasm and various cell organelles which are responsible for performing certain specific functions to carry out life’s processes. These are endoplasmic reticulum, plastids in plant cells, Golgi apparatus, lysosomes, mitochondria, vacuoles.
know more:
- The Cells were also observed under compound microscope with higher magnification by Anton Van Leeuwenhoek who concluded that the cells are alive they possess motility and cells were named animalcules.
- The Robert Brown in 1883provided the first insight to cell structure. He described the presence of nucleus present in the cells of orchids.
The Various functions of cell are :
- It provides support and structure.
- It facilitates growth mitosis.
- It allows transport of various substances.
