1 Organelle: specific parts of a cell Cell: smallest level of organism Tissue: a bunch of cells Organ: a bunch of tissues Organ system: a bunch of organs Organism: several organ systems Please update your vocab sheet # 8 # 5 # 71 # 4 # 6 # 7

2 Body Organism Organ System OrganellesCell Tissue Organ

3 A closer look at the plant and animal cell EUKARYOTES

4 Microtubules: Golgi Bodies: Smooth Endoplasmic Reticulum: Nuclear Membrane: Nucleolus: Nucleus:Cytoplasm: Rough Endoplasmic Reticulum: Mitochondria: Ribosomes: Vacuoles: Centriole: Cell Membrane: Cilia: Lysosomes:

5 Microtubules Mitochondria Cell Membrane Rough and smooth Endoplasmic Reticulum Golgi Body Nucleolus Nucleus Vacuole Chloroplast Microbody Ribosomes Cell Wall Cytoplasm

6 Cell Membrane

7 outer boundary of the cell allows only certain materials in/out of cell – Controls osmosis – the movement of water in/out of cell –Controls diffusion – the movement of nutrients in/out of cell Analogy: fence

8 Mitochondria

9 breaks down food and releases energy to the cell The more energy the cell needs…the more mitochondria in the cell Analogy: batteries

10 Nucleus Nucleus Membrane Chromosomes Nucleolus Nucleus; Nucleolus; Nuclear membrane

11 NucleusNucleolusNuclear Membrane Function regulates all cell activity Contains all RNA & DNA Regulates the transport of materials in and out of nucleus What does it make? Ribosomes Analogy BrainNerves in the brain Skull bone Nucleus; Nucleolus; Nuclear membrane

12 Cytoplasm

13 Gel-like substance between the cell membrane holding all the cell's internal organelles Analogy: grass

14 Endoplasmic reticulum

15 allows molecules to be transferred between the cell’s space and the cytoplasm provides a pipeline between the nucleus and the cytoplasm Analogy: highway

16 Ribosomes Ribosome

17 Ribosomes Makes proteins for the cell Analogy: factory building

18 Vacuole Animal Cell Plant Cell

19 Vacuole Animal Cell Plant Cell plays roles in: digestion release of waste products storage Analogy: stomach

20 Cilia

21 Helps the cell move Helps move things in/out of cell

22 Lysosome

23 Removes waste from the cell Analogy: trash can/recycling bin

24 Microtubules

25 plays roles in: cell locomotion Mitosis (Cell Division) cell transport Analogy: conveyer belt

26 Golgi body (apparatus)

27 stores, packages and distributes the proteins made in ribosomes Analogy: post office Golgi body (apparatus)

28 Cell Wall (plants)

29 prevents over-expansion when water enters the plant cell Analogy: rubber band

30 Chloroplast (plants)

31 takes energy from the sun & turns it into oxygen through photosynthesis Analogy: kitchen
