Introduction to Cells Plant Cell Smooth endoplasmic Vacuole reticulum Nuclear envelope Ribosome (attached) (free) Smooth endoplasmic reticulum Nucleus Rough endoplasmic reticulum Nucleolus Golgi apparatus Mitochondrion Cell wall Cell Membrane Chloroplast Vacuole Plant Cell

Prokaryotic vs. Eukaryotic Cell membrane Cytoplasm Prokaryotic Cell Nucleus Eukaryotic Cell Organelles

Cell Theory All living things are composed of one or more cells The smallest living organisms are single cells, cells are the functional units of multicellular organisms. All cells come from pre-existing cells.

All cells share common Features All cells are enclosed by a cell membrane known as a plasma membrane Separates cells contents from the environment Regulates the flow of materials in and out of the cell, nutrients in, waste out Cell membrane controls interactions between cells

All cells share common Features use DNA as a blue print contain Cytoplasm Contain Ribosomes Made up of Proteins, Lipids, Carbohydrates and Nucleotides Obtain energy and nutrients from the environment

Eukaryotic Organelles Nucleus, Nuclear envelope, nucleolus Cell wall, Plasma membrane, membrane Proteins Cytoplasm, Cytoskeleton Mitochondria, Chloroplast Endoplasmic reticulum, Smooth & Rough Golgi Complex, Lysosomes Central vacuole, other vesicles and vacuoles Centrioles, Cilia and Flagella
