OVERVIEW OF LESSON 1 Cell Structure Lesson 1
- Slides: 25
OVERVIEW OF LESSON 1 • Cell Structure
Lesson 1: Cell structure 1) To know the ultrastructure of eukaryotic and prokaryotic cells on electron microscopes 2) To know the differences between eukaryotic and prokaryotic structure 3) To know the structures of DNA & RNA
Cells are the basic unit of life. They are small membrane-bound structures containing several smaller structures called organelles. Two categories: Eukaryotic cell, including the cells of animals and plants Prokaryotic cell, including bacterial cells
Label what you can remember of the parts of the cell from the following slides and then answer the multi-choice questions.
Which structures are present in animal and plant cells? a. b. c. d. Vacuole, nucleus and cell membrane Nucleus, cell wall, cytoplasm Nucleus, cell membrane, cytoplasm Cell membrane, chloroplast, cell wall
Which structures are present only in plant cells? a. b. c. d. Cell membrane, nucleus, cytoplasm Cell wall, cell membrane, vacuole Nucleus, chloroplast, cytoplasm Chloroplast, cell wall, vacuole
What is the function of the chloroplast? a. b. c. d. Controls the cell Stores water and mineral ions Makes glucose by photosynthesis Controls what enters and leaves the cell
What is the function of the cell membrane? a. b. c. d. Supports and protects the cell Controls what enters and leaves the cell Metabolic reactions occur here
What is the function of the cell wall? a. b. c. d. Supports and protects the cell Stores water and mineral ions Controls the cell Controls what enters and leaves the cell
What is the function of the cytoplasm? a. b. c. d. Stores water and mineral ions Metabolic reactions occur here Controls what enters and leaves the cell Supports the cell
What is the function of the permanent vacuole? a. b. c. d. Supports and protects the cell Controls what enters and leaves the cell Controls the cell Stores water and mineral ions
What is the function of the nucleus? a. b. c. d. Supports and protects the cell Controls what enters and leaves the cell Metabolic reactions occur here
Research Presentation Task Compare prokaryotic and eukaryotic cells 1. 2. What is the ultrastructure of prokaryotic and eukaryotic cells? What is the function of each organelle? Include the following: • Diagrams • Nuclei, SER, RER, mitochondria, vesicles, lysosomes, golgi apparatus, chloroplasts, vacuoles, cell wall, ribosomes, flagella, nucleoid, plasmid, mesosome, pili, slime capsule • www. cellsalive. com • www. biologycorner. com/worksheets/cellsalive. html Needs to be more detailed than this diagram
