2 Features of all cells Plasma membrane Nucleoid or nucleus Cytoplasm
Transport proteins Receptor proteins Markers Nucleoid or nucleus Cytoplasm

3 Cell size

4 Cell type

5 Eukaryotes Plasma membrane Nucleus Endoplasmic reticulum Golgi bodies
Lysosomes Mitochondria Cytoskeleton Centrioles Peroxisomes

6 Plant cells

7 Endosymbiosis Eukaryotic organelles evolved
Mitochondria and chloroplasts

8 Cell membrane Plasma membrane Phospholipids Transmembrane proteins
Interior protein network Cell surface markers

9 Cell membrane

10 Cell membrane

11 Proteins

12 Movement across membrane
1. Passive transport Diffusion Osmosis Facilitated diffusion (carriers) 2. Bulk transport Exocytosis Endocytosis 3. 3. Active transport Requires energy Na-K pump
