3. Identify several basic tissues of the human body and several main tissues of the plant body.

Cell division and differentiation PPT, part 2: cell division

Living organisms generally have growth phenomena, that is, they can grow from small to large. For example, a young apple sapling will grow into a leafy apple tree.

Have you ever wondered why no living organism can grow from small to large?

What is cell division?

Cell division is the process by which one cell divides into two cells.

Use your brain

1. What is the most obvious change during cell division?

2. Cell division can be divided into what two basic processes?

3. Are the two cells formed by cell division similar in structure?

4. What are the similarities and differences between the division process of animal cells and that of plant cells?

Cell division and differentiation PPT, Part 3 content: Cell differentiation

Why do the various cells of an organism developed from a fertilized egg have obvious differences in shape, structure and function? This is related to cell differentiation.

What is cell differentiation?

Under normal circumstances, under the influence of genetic material, the shape, structure, and function of new cells produced after cell division differ as the cells grow. This is cell differentiation.

Groups of cells with similar shapes, identical structures, and certain functions are called tissues.

The result of cell differentiation is: the formation of tissues
