The Cell
Objectives The students will be able to:
-
1. differentiate plant cells and animal cells.
-
2. identify and describe two types of protoplasm.
-
3. identify and discuss the function of the nucleus.
Vocabulary cell, protoplasm, nucleus, meiosis, mitosis
Material Needed paper, pencil, microscope, wall posters of animal and plant cells
Brainstorming Questions
-
1. How many cells do you think you have in your body?
-
2. How does life begin in living organisms?
-
3. Are cells replaced in plants and animals? Why do you think they do or do not?
-
4. Can you see cells on your body?
Procedures Discuss the vocabulary words with emphasis placed on the nucleus of the cell because it controls most of the cell activity. Make sure that the students are aware that there are several kinds of cells found in the body, such as bone, nerve, blood, skin, etc. Point out that animal cells have no rigid cell was as found in plant cells. Make sure that the students are aware that the nucleus has a major role with the cells’ reproductive process. Using the diagrams in the unit point out the mitosis and meiosis process of cell division. Point out how they are alike as well as how they are different. There are over 10,000,000,000 cells in the human body.
