1 Cells & Cell Organelles The Building Blocks of Life AP Biology
2 Types of cells bacteria cells Prokaryote - no organelles Eukaryotes - organelles animal cells plant cells
3 Cell size comparison Animal cell Bacterial cell most bacteria 1-10 microns eukaryotic cells microns micron = micrometer = 1/1,000,000 meter diameter of human hair = ~20 microns
4 Why study cells? Cells Tissues Organs Bodies bodies are made up of cells cells do all the work of life!
5 The Work of Life What jobs do cells have to do for an organism to live breathe gas exchange: CO 2 vs. O 2 eat take in & digest food make energy ATP build molecules proteins, carbohydrates, fats, nucleic acids remove wastes control internal conditions respond to external environment build more cells ATP growth, repair, reproduction & development
6 Organelles Organelles do the work of cells each structure has a job to do keeps the cell alive; keeps you alive Model Animal Cell
7 Cells need power! Making energy to fuel daily life & growth, the cell must take in food & digest it take in oxygen (O 2 ) ATP make ATP remove waste organelles that do this work cell membrane lysosomes vacuoles & vesicles mitochondria
8 Cell membrane Function separates cell from outside controls what enters or leaves cell O 2,CO 2, food, H 2 O, nutrients, waste recognizes signals from other cells allows communication between cells Structure double layer of fat phospholipid bilayer receptor molecules proteins phosphate head lipid tail
9 cytoplasm jelly-like material holding organelles in place cell membrane cell boundary controls movement of materials in & out recognizes signals
10 Vacuoles & vesicles small food particle Function moving material around cell storage Structure membrane sac vacuole digesting food inside cell
11 Food & water storage plant cells central vacuole food vacuoles animal cells contractile vacuole
12 cytoplasm jelly-like material holding organelles in place vacuole & vesicles transport inside cells storage cell membrane cell boundary controls movement of materials in & out recognizes signals
13 Lysosomes small food particle vacuole lysosomes Function digest food clean up & recycle digest broken organelles Structure membrane sac of digestive enzymes digesting broken organelles digesting food
14 cytoplasm jelly-like material holding organelles in place vacuole & vesicles transport inside cells storage lysosome food digestion garbage disposal & recycling cell membrane cell boundary controls movement of materials in & out recognizes signals
15 Mitochondria Function make ATP energy from cellular respiration sugar + O 2 ATP fuels the work of life Structure double membrane ATP in both animal & plant cells
16 cytoplasm jelly-like material holding organelles in place vacuole & vesicles transport inside cells storage lysosome food digestion garbage disposal & recycling mitochondria make ATP energy from sugar + O 2 cell membrane cell boundary controls movement of materials in & out recognizes signals
17 Plants make energy two ways! Mitochondria ATP make energy from sugar + O 2 cellular respiration sugar + O 2 ATP Chloroplasts make energy + sugar from sunlight photosynthesis sunlight + CO 2 ATP & sugar ATP = active energy sugar = stored energy build leaves & roots & fruit out of the sugars sugar ATP
18 Mitochondria are in both cells!! animal cells plant cells mitochondria chloroplast
19 cytoplasm central vacuole storage: food, water or waste mitochondria make ATP in cellular respiration cell membrane cell boundary controls movement of materials in & out recognizes signals lysosome digestion & clean up cell wall support chloroplast make ATP & sugars in photosynthesis
20 Cells need workers (proteins)! Making proteins to run daily life & growth, the cell must read genes (DNA) build proteins structural proteins (muscle fibers, hair, skin, claws) enzymes (speed up chemical reactions) signals (hormones) & receptors organelles that do this work nucleus ribosomes endoplasmic reticulum (ER) Golgi apparatus
21 Proteins do all the work! one of the major job of cells is to make proteins, because proteins do all the work! structure enzymes signals receptors DNA proteins cells
22 Nucleus Function control center of cell protects DNA instructions for building proteins Structure nuclear membrane nucleolus ribosome factory chromosomes DNA
23 cytoplasm jelly-like material holding organelles in place vacuole & vesicles transport inside cells storage lysosome food digestion garbage disposal & recycling nucleus protects DNA controls cell chromosomes DNA mitochondria make ATP energy from sugar + O 2 cell membrane cell boundary controls movement of materials in & out recognizes signals
24 Ribosomes Function protein factories read instructions to build proteins from DNA Structure 2 subunits some free in cytoplasm some attached to ER Ribosomes on ER large subunit small subunit
25 cytoplasm jelly-like material holding organelles in place vacuole & vesicles transport inside cells storage lysosome food digestion garbage disposal & recycling nucleus protects DNA controls cell mitochondria make ATP energy from sugar + O 2 cell membrane cell boundary controls movement of materials in & out recognizes signals ribosomes builds proteins
26 Endoplasmic Reticulum Function part of protein factory helps complete the proteins makes membranes Structure rough ER ribosomes attached works on proteins smooth ER makes membranes
27 cytoplasm jelly-like material holding organelles in place vacuole & vesicles transport inside cells storage lysosome food digestion garbage disposal & recycling nucleus protects DNA controls cell mitochondria make ATP energy from sugar + O 2 cell membrane cell boundary controls movement of materials in & out recognizes signals ER helps finish proteins makes membranes ribosomes builds proteins
28 Golgi Apparatus Function finishes, sorts, labels & ships proteins like UPS headquarters shipping & receiving department ships proteins in vesicles UPS trucks Structure membrane sacs vesicles carrying proteins transport vesicles
29 cytoplasm jelly-like material holding organelles in place vacuole & vesicles transport inside cells storage lysosome food digestion garbage disposal & recycling nucleus protects DNA controls cell mitochondria make ATP energy from sugar + O 2 cell membrane cell boundary controls movement of materials in & out recognizes signals ER helps finish proteins makes membranes ribosomes builds proteins Golgi apparatus finishes, packages & ships proteins
30 nucleus DNA endoplasmic reticulum protein on its way! TO: RNA vesicle TO: ribosomes TO: vesicle Making Proteins protein Golgi apparatus TO: finished protein
31 nucleus control cell protects DNA cytoplasm endoplasmic reticulum processes proteins makes membranes ribosomes make proteins Golgi apparatus finish & ship proteins mitochondria make ATP in cellular respiration cell membrane cell boundary controls movement of materials in & out recognizes signals lysosome digestion & clean up central vacuole storage: food, water or waste cell wall support chloroplast make ATP & sugars in photosynthesis
32 Cells need to make more cells! Making more cells to replace, repair & grow, the cell must copy their DNA make extra organelles divide the new DNA & new organelles between 2 new daughter cells organelles that do this work nucleus centrioles
33 Centrioles Function help coordinate cell division Structure one pair in each cell motor proteins
34 cytoplasm jelly-like material holding organelles in place vacuole & vesicles transport inside cells storage lysosome food digestion garbage disposal & recycling nucleus protects DNA controls cell centrioles cell division mitochondria make ATP energy from sugar + O 2 cell membrane cell boundary controls movement of materials in & out recognizes signals ER helps finish proteins makes membranes ribosomes builds proteins Golgi apparatus finishes, packages & ships proteins
35 Cell Summary Cells have 3 main jobs make energy need food + O 2 cellular respiration & photosynthesis need to remove wastes make proteins need instructions from DNA need to chain together amino acids & finish & ship the protein make more cells need to copy DNA & divide it up Our organelles do all those jobs!
