Cellular Structure

Types of Cells Prokaryotes : No Nucleus, DNA, ribosomes, cell walls, cell membrane Examples: Bacteria  E.coli, Salmonella Eukaryotes : True nucleus (DNA inside a nuclear membrane), ribosomes, cell walls (maybe), cell membrane, endoplasmic reticulum, Golgi bodies, Cytoskeleton, Vacuoles, Vesicles, Centrioles (maybe), Cilia and Flagella, Mitochondria, Chloroplasts (maybe) Examples: plants, animals, fungus, Protista Prokaryotes : No Nucleus, DNA, ribosomes, cell walls, cell membrane Examples: Bacteria  E.coli, Salmonella Eukaryotes : True nucleus (DNA inside a nuclear membrane), ribosomes, cell walls (maybe), cell membrane, endoplasmic reticulum, Golgi bodies, Cytoskeleton, Vacuoles, Vesicles, Centrioles (maybe), Cilia and Flagella, Mitochondria, Chloroplasts (maybe) Examples: plants, animals, fungus, Protista

Cellular Organelles: 1) Cytoplasm : Everything between the nucleus and the cell membrane Cytosol : semi-fluid material of the cytoplasm 2) Cell Membrane : Made of phospholipids and proteins Regulates what goes in and out of the cell 1) Cytoplasm : Everything between the nucleus and the cell membrane Cytosol : semi-fluid material of the cytoplasm 2) Cell Membrane : Made of phospholipids and proteins Regulates what goes in and out of the cell

3) Nucleus : Regulates Cell Functions Contains: DNA – controls cell process Nucleolus – center of ribosome production 3) Nucleus : Regulates Cell Functions Contains: DNA – controls cell process Nucleolus – center of ribosome production

4) Ribosomes : synthesize proteins

5) Endoplasmic Reticulum : Two Types Rough ER : Make proteins “rough” because ribosomes are attached to the outside Smooth ER: 1. Processes carbohydrates 2. Stores Calcium ions 3. Makes lipids 4. Detoxifies poisons Smooth & Rough ER form vesicles that pinch off and travel to the Golgi bodies. 5) Endoplasmic Reticulum : Two Types Rough ER : Make proteins “rough” because ribosomes are attached to the outside Smooth ER: 1. Processes carbohydrates 2. Stores Calcium ions 3. Makes lipids 4. Detoxifies poisons Smooth & Rough ER form vesicles that pinch off and travel to the Golgi bodies.

6) Golgi Bodies : Series of flattened membranes - sort and repackage materials from the ER for storage or secretion

7) Lysosome : Digests materials in the cell Digested materials go to mitochondria to generate energy

Lysosomes

ENDOMEMBRANE SYSTEM ER  Vesicles  Golgi Bodies  Vesicles for storage or secretion ENDOMEMBRANE SYSTEM ER  Vesicles  Golgi Bodies  Vesicles for storage or secretion

8) Mitochondria : Power house of the cell Transform food into energy Cellular Energy = ATP – Adenosine Triphosphate 8) Mitochondria : Power house of the cell Transform food into energy Cellular Energy = ATP – Adenosine Triphosphate

9) Chloroplasts : Site of Photosynthesis

10) Cytoskeleton : System of tubes and filaments that give shape and movement to a cell TYPES: Microtubules : tiny tubes used for moving things around inside or outside of a cell Ex: Cilia and Flagella – move cells or things across the surface of a cell Spindle Fibers – move chromosomes around in cell division Centrioles – cluster of short tubes that form spindle fibers in animal cells 10) Cytoskeleton : System of tubes and filaments that give shape and movement to a cell TYPES: Microtubules : tiny tubes used for moving things around inside or outside of a cell Ex: Cilia and Flagella – move cells or things across the surface of a cell Spindle Fibers – move chromosomes around in cell division Centrioles – cluster of short tubes that form spindle fibers in animal cells

Cytoskeleton

Cilia and Flagella

Spindle Fibers and Centrioles

Microfilament : tiny filaments used to move things in cells Ex: Actin filaments in muscles used for contraction with Myosin proteins Intermediate filaments : fibers that give the shape to a cell – the actual real skeleton in a cell Microfilament : tiny filaments used to move things in cells Ex: Actin filaments in muscles used for contraction with Myosin proteins Intermediate filaments : fibers that give the shape to a cell – the actual real skeleton in a cell

11) Vacuoles : Storage centers of the cell – mainly in plants Central Vacuole of Plants – like a big water balloon Stores water, salts, poisons 11) Vacuoles : Storage centers of the cell – mainly in plants Central Vacuole of Plants – like a big water balloon Stores water, salts, poisons

12) Cell Wall : Protective layer that gives support to tissues Plants: Cellulose Fungi: Chitin Bacteria: Peptidoglycan (proteins and sugars) 12) Cell Wall : Protective layer that gives support to tissues Plants: Cellulose Fungi: Chitin Bacteria: Peptidoglycan (proteins and sugars)
