Early Light Microscope
First to observe living cells
1838-plants have cells
1839-animals have cells
1821-1902-cells come only from other cells
Cell Theory 1
all organisms are composed of one or more cells.
Cell Theory 2
Cells are the basic structure and function in an organism.
Cell Theory 3
Cells come from reproduction of existing cells only.
Powerhouse of the cell.
Where is ATP produced?
Site of Protein Synthesis
builds lipids, breaks down glycogen
Makes proteins, has ribosomes.
Helps maintain Homeostasis
Microfilaments, intermediate filaments, microtubles.
How does the Cytoskeleton move?
Cilia and Flagella.
Lysosomes, peroxisomes, Protein synthesis.
Modify, concentrate and package proteins.
How are vesicles transported to the plasma membrane and discharged?
Acts as a barrier and covers the surface of the cell, allows cell to excrete waste.
Basic Parts of Cells:
Nucleus, Cytoplasm, and Plasma Membrane.
What has a phospholipid bilayer?
What makes up 90% of the cell?
What does the central vacuole store?
water, enzymes, toxins
What makes a plant stand up?
If the central vacuole is filled with water.
What two plastids exist?
Chloroplasts and Chromoplasts.
What are chloroplasts?
What are chromoplasts?
Colorful pigments. May or may not be involved in photosynthesis.
