3. Identify several basic tissues of animals and several basic tissues of plants.
4. Pay attention to the value of cell research in preventing and treating cancer.
Emotions, attitudes and values
Cultivate students' awareness of cooperation, communication, and expression.
Important points in teaching:
focus
1. Master the basic process of cell division.
2. The concept of organization and types of organizations.
difficulty
1. Explain the general changes in genetic material during cell division.
2. Describe cell division.
Cell division and differentiation PPT, Part 2: Cell division
Cell division causes the number of cells to _________. The volume of a newly divided cell is ________, and as the cell ________, its volume is ________. The number of cells is ________, the volume is ________, and the organism will continue to grow.
Schematic diagram of plant cell division process
The nucleus is first divided into two; then, the cytoplasm is divided into two parts, each containing a nucleus; finally, a new cell membrane is formed in the center of the original cell, and a new cell wall is formed.
Schematic diagram of animal cell division process
Clear up doubts:
1. The cell nucleus is divided into two, is the genetic material inside it also divided into two?
2. If not, how to achieve the stability of genetic material in the nucleus? What is the significance of this?
practice
1. Chromosomes exist in ( )
A cytoplasm B cell membrane
C nucleus D vacuole
2. What is related to the growth phenomenon of living organisms ( )
An increase in the number of A cells
Increase in B cell size
Increased number and size of C cells
D None of the above
Cell division and differentiation PPT, Part 3: Cell differentiation
Under normal circumstances, new cells produced after cell division, under the action of _______, have differences in their ____, ____ as the cells grow. This is cell differentiation. We call groups of cells with similar shapes, functions, and identical structures called ____.
Cell Differentiation
The process by which cells after division change in different directions in form, structure, and function.
Organization formation:
The result of cell differentiation is the formation of tissues
organize
A group of cells formed by many cells with similar morphology, structure and function, united together
practice
1. The process of organization formation is roughly expressed as ( )
A. Cell division → cell growth → cell differentiation → tissue
B. Cell differentiation → cell division → cell growth → tissue
C. Cell growth→Cell differentiation→Cell division→Tissue
D. Cell division → Cell differentiation → Cell growth → Tissue
2. The formation of various tissues is the result of cell differentiation.
