1. THE CELL What does this mean? The basic unit of live. That it is capable of surviving by itself, every organism on the planet is formed by cells, and it has genetic material (hereditary information) that is passed from generation to generation. Home work: bring a reading report of the cell theory

2. THE CELL Cells are mainly formed of water, but present in their structure are proteins, carbohydrates, and nucleic acids (DNA). There are two types of cells: The Prokaryotic cell and the Eukaryotic cell ¿¿The difference?? What about unicellular and multicellular organisms?

3. Workshop 1.Why do you think that cells are called the building block of live? 1.Why do you think eukaryotes are more complex than prokaryotes? THE CELL

4. Structure Cell membrane Cell wall Nucleus THE CELL Which is their importance?

5. Activity In groups of two: 1.Make a parallel between the prokaryotic cell and the eukaryotic cell 2.Make a parallel between the animal cell and the plant cell. THE CELL

6. ANIMAL CELL http://www.enchantedlearning.com/subjects/animals/cell/

7. THE CELL PLANT CELL http://www.enchantedlearning.com/subjects/plants/cell/

8. Organelles THE CELL

9. Organelles In base groups: – Each member of the group brings information of the organelles: Cytoplasm, Cytoskeleton, Golgi Apparatus, Endoplasmic Reticulum, Mitochondria, Vacuole, Lysosomes, Chloroplasts, Ribosomes. – Discuss about how those organelles and structures influence the function of the cells. – Present the conclusions of the discussion. THE CELL

10. Organelles Golgi Apparatus (or Golgi bodies): they sort or classify proteins and put them in vesicles. Where do these vesicles go? Cytoskeleton: it gives shape and structure to the cell. It also holds all the organelles within the cell. THE CELL

11. QUIZ 1.What is the difference between Eukaryotes and Prokaryotes 2.What is the function of: a)The cell wall? b)The ribosomes? c)The Golgi bodies? 3.How do cells process energy? THE CELL
