• What is a cell?
• What are some components of a cell?
• What are 3 differences between a plant and animal cell?
• What is the difference between a prokaryotic and eukaryotic cell?
What are some characteristics of living things?
• obtain and use materials and energy• respond to their environment• most living things move in some way• reproduce• maintain a stable internal environment• grow and develop• are made of cells
Cell Theory
• all living things are composed of cells
• all cells come from other cells
• the cell is the basic unit of structure and function in living systems
Most Cells…
• Depend on external energy sources
• Exchange material with their environments
• Are small
• Use their DNA to regulate what they do
• Have the same basic components
• Cell Membrane – controls what goes in and out
• Cytoplasm – fills cell (gooky stuff)
• Cilia and flagella - movement
cilia/flagella
• Cell membrane• Nucleus• Nuclear
envelope/pore• Chromatin (DNA)• Cytoplasm• Mitochondrion• Golgi body
• Centriole• Microtubule• Vacuole• Lysosome• Ribosome• Endoplasmic
reticulum (ER)
Plant Cells
• Large central vacuole (store water)
• Chloroplasts (for photosynthesis)
• Cell wall (for support)
