1 Cell Types and Cell Structure

2 Prokaryotic vs. Eukaryotic
nucleus membrane enclosed organelle chromosomes in pairs streaming in the cytoplasm cell division by mitosis complex flagella larger ribosomes complex cytoskeleton cellulose in cell walls DNA bound to histone proteins no nucleus no membrane enclosed organelles single chromosome no streaming in the cytoplasm cell division without mitosis simple flagella smaller ribosomes simple cytoskeleton no cellulose in cell walls no histone proteins

3 Prokaryotic vs. Eukaryotic
Examples: Bacteria Examples: Plant cells Animal cells Fungi Protists

4 Plasma Membrane Plasma membrane 1. Surrounds Cells
2. Protected by cellulose and protein cell wall in plants Plasma Membrane

5 Cytoplasm Cytoplasm 1. Fluid (Cytosol) and organelles that make up
the inside of the cell Cytoplasm

6 Nucleus Nucleus 1. Membranous nuclear envelope
2. Chromosomes of DNA and protein (Histones) Nucleus

7 Endoplasmic reticulum (ER)
1. Rough ER - Transport of proteins (roughness is the attached ribosomes) 2. Smooth ER – Processing and transport of lipids Endoplasmic reticulum (ER)

8 Ribosomes Ribosomes 1. Attached to Rough ER
2. Site of protein synthesis Ribosomes

9 Golgi Apparatus Golgi Apparatus (Golgi body, Golgi complex)
1. Assembly and editing of proteins Golgi Apparatus

10 Lysosomes Lysosomes 1. Contain enzymes that break down and help
recycle large proteins in animal cells Lysosomes

11 Mitochondria 1. Powerhouse ‑ site of ATP synthesis Mitochondria

12 Flagella and Cilia Flagella and Cilia
1. Cell surface projections for movement Flagella and Cilia

13 Microtubules and Microfilaments
1. Structural components of the cell (cytoskeleton) in eukaryotes Microtubules and Microfilaments

14 Vacuoles 1. Large central vacuoles in plant cells contain enzymes and pigments in plant cells Vacuoles

15 Chloroplasts Chloroplasts 1. Photosynthetic organelles in plant cells,
containing the chlorophyll pigments Chloroplasts

16 Comparison: Plant cells Animal cells
Large, central vacuole Chloroplasts Rigid cell wall outside of cell membrane No large, central vacuole No chloroplasts No rigid cell wall
