Presentation Transcript

  1. Cell Structure and Function Unit 2A

  2. Structure: Tough carb. covering (cellulose). Plant cells Only!! Function: Protects plant cells and gives them shape. Cell Wall

  3. Structure: Phospholipid bilayer with proteins Function: Controls what enters andleaves cell Cell Membrane

  4. Structure: Two (2) Phospholipid bi-layers with pores Function: Controls what enters and leaves nucleus Nuclear Envelope

  5. Structure: The jelly-like substance fills the cell. Function: Contains stuff needed for reactions and medium for organelles Cytoplasm

  6. Structure: Network of microtubules and microfilaments Function: Provides internal cell support and helps change cell shape. Cytoskeleton

  7. Structure: Thin, short filaments Function: Used for cell movement Cilia

  8. Structure: Long whip-like structure. Function: Used for cell movement. Flagella

  9. Structure: Bundles of microtubules and microfilaments Function: Help separate chromosomes in cell division. Centrioles

  10. Structure: DNA strands that form an “X” Function: Contains heredity information and instructions. Chromosomes

  11. Structure: Large, dark, porous organelle. “Brain of Cell” Function: Control center of the cell. Regulates cell activity. Contains DNA Nucleus

  12. Structure: Small, round dense structure inside the nucleus. Function: Produces ribosomes. Nucleolus

  13. Structure: Vesicles filled with enzymes. “Recycle Bin” Function: Digest and breakdown materials in the cell. Lysosomes

  14. Structure: Very small dot-like structure made of R-RNA Function: Makes proteins. Ribosomes

  15. Structure: Network of membranes throughout the cell. “Cell Highway” Function: Transports materials throughout the cell. Rough ER: studded with ribosomes; it makes proteins Smooth ER: no ribosomes; it makes lipids Endoplasmic Reticulum (ER)

  16. Structure: Flattened membrane-bound sacks. “UPS Center” Function: Modify, package and ships proteins. Golgi Apparatus

  17. Structure: Cigar-shaped organelle filled with folded inner membranes. Function: Powerhouse of the cell, energy changer (food to ATP). Mitochondria

  18. Structure: Round, green organelles filled with stacks of green disks. Function: Energy changer in photosynthesis (solar energy to chemical energy – sugar). Chloroplasts

  19. Structure: Vesicle. Animals – small Plant - large “Tupperware” Function: Storage compartment for salt, water, food and waste. Vacuole
