The important topics and sub-topics of Lakhmir Singh Solutions for Chapter 8 are provided below:
Cells are generally called the basic building blocks of all living things. It is a structural and functional unit of living creatures. Usually, cells may be compared to bricks as they are gathered to make a building. In the same way, cells are gathered to make the body of every organism. All living organisms are made up of cells.
Types of Cell
Generally, cells are divided into two types:
- Prokaryotic Cells: The cells having atomic material without a nuclear crust are called prokaryotic cells. The entities with these kinds of cells are termed prokaryotes. “Pro” means primitive and “karyon” means nucleus. For example, bacteria and blue-green algae.
- Eukaryotic cells: The cells having a well-controlled nucleus with a nuclear crust are titled as eukaryotic cells. All creatures other than bacteria and blue-green algae are named as Eukaryotes. “Eu” means true and “karyon” means nucleus.
Characteristics of Cell
There are three basics characteristics of the cell and are listed as follows:
- Cell Membrane
- Genetic Material
- Metabolic Machinery
Shape of Cell
The shape of the cell is influenced by its function. It may change or remain the same. The different shapes of the cell are listed as follows:
- Disc like
- Spindle like
Size of Cell
All the cells have different sizes. In animals, the smallest cell size is found in Mycoplasma and is 0.1 whereas the largest cell is in an ostrich egg and it is 17 cm in diameter. Considering a human being, the smallest cell is a Red Blood Cell of 6-8 micrometres whereas the longest cell is a nerve cell of up to 100 microns.
