What is a cell?
In this section the learners now expand their knowledge and learn the various cell structures and related functions. The roles of the organelles within the cells need to be introduced and relate structure and location of organelles to their function. Cells differ in size, shape and structure and therefore carry out specialised functions. Link this to tissues. The differences between plant and animal cells can be linked to Grade 9. The cell theory developed in by microbiologists Schleiden and Schwann describes the properties of cells. It is an explanation of the relationship between cells and living things.

Illustration of a plant cell with the organelles and components labeled. Thursday, May 23, As is often repeated, cells are the basic building blocks of all life. They are responsible for generating the energy that sustains life, eliminating waste, and replicating to replace damaged tissues. From single-celled organisms to humans, complex function is possible because of cells and the versatile functions of their parts. Some organisms consist of a single cell with only the most basic components: genetic material DNA , ribosomes, cytoplasm , and a cell membrane.

What is a cell?
Organelles make up the subunits of a cell. There are numerous each with their own function. The plasma membrane is the organelle that encapsulates the contents of the cell. Apart from encapsulating cell contents, the plasma membrane also plays a vital role in regulating the movement of substances in and out of the cell.

Humans are made up of trillions of cells — the basic unit of life on earth. In this article, we explain some of the structures found in cells and describe a few of the many types of cell found in our bodies. Cells can be thought of as tiny packages that contain minute factories, warehouses, transport systems, and power plants. They function on their own, creating their own energy and self-replicating — the cell is the smallest unit of life that can replicate. However, cells also communicate with each other and connect to create a solid, well stuck-together animal. Cells build tissues, which form organs; and organs work together to keep the organism alive. Robert Hook first discovered cells in
Organelles make up the subunits of a cell. There are numerous each with their own function. The plasma membrane is the organelle that encapsulates the contents of the cell. Apart from encapsulating cell contents, the plasma membrane also plays a vital role in regulating the movement of substances in and out of the cell. As such, it is actively involved in such both passive and active transportation to and from the cell. These processes also help maintain balance even when conditions outside the cell change. The plasma membrane is made up of two layers of phospholipids phospholipids bilayer.
