Biology ch. 5 notes
Chapter 5 notes and vocab
| Question | Answer |
|---|---|
| Who created the first microscope? | Anton van Leeuwenhoek |
| Who named the "cell" | Robert Hooke |
| Robert Brown discovered what? | The nucleus |
| Who discovered all plants are made up of cells? | Matthias Schleiden |
| Theodore Shwann | Discovered all plants and animals are made up of cells |
| Who discovered all cells come from exisiting cells? | Rudolf Virchow |
| What is made up of cells? | All living things |
| Cells are? | The basic unit of structure and function |
| All cells come from? | Cells |
| What is selective permeable? | The cell membrane |
| Phospholipid bilayer | Hydrophilic Heads Hydrophobic Tails |
| What is stuck in the membrane? | Carbohydrates and proteins |
| Organelles | tiny structures that are specialized to do a specific job |
| Mitochondria | The "Power House" Double membrane DNA Folds: “ Cristae ” that form a matrix for increased surface area for power production |
| Ribosomes | Produce proteins Made of RNA and protein |
| Endoplasmic Reticulum (ER) | Transport material Smooth Er (no ribosomes), stores enzymes and chemicals Rough ER (ribosomes), many proteins are released from the attached ribosomes |
| What packages the proteins by attaching carbohydrates and lipids? | The Golgi Apparatus (Golgi Body) |
| Lysosomes | Contain chemicals and enzymes to breakdown cell materials NOT in Plant Cells! |
| What engulf particles for transfer across membrane | Endocytosis |
| Cell Wall (in plants) | Porous- allows H₂O, O₂, CO₂ in and out Pectin- gluey substance that holds cells together Secondary cell wall- in woody plant cells (made of cellulose and lignin), more rigid |
| What is the nucleus? | the "conrol center" |
| Double membrane with nuclear pores Around nucleus | Nuclear Envelope |
| Nucleolus | Makes the RIBOSOMES!! (which produce PROTEINS) |
| Condensed Chromatin | Chromosomes |
| Vacuoles | Very large in plant cells Plastids: plant organelle that stores food and pigments |
| Leukoplasts | store starch |
| Chromoplasts | store pigments |
| Cytoskeleton | filaments and fibers used for support and cell movement |
| Microtubules | support, movement, spindle fibers in cell division and centrioles, cilia/flagella (for movement) |
| Microfilaments | movement (in cytoplasm), support “cytoplasmic streaming” |
| Diffusion | Movement from HIGH concentration to a LOWER concentration No energy needed (passive) Movement will continue until equilibrium is reached! |
| Osmosis | Diffusion of water molecules |
| Force exerted by osmosis Moves water across membranes from a more dilute solution into a more concentrated solution Inside cell= LOW WATER CONCENTRATION, so there is a constant flow of water BURSTS!! Other cells can pump out water: “Contractive vacuo | Osmotic Pressure |
| Passive Transport | No energy required to move molecules through the membrane |
| Facilitated Diffusion | Uses a carrier protein to transport molecules through the membrane Type of diffusion (HIGH to LOW) |
| requires energy to move molecules through the membrane | Active Transport |
| Pump molecules by movements of the membrane | Endocytosis- pocket/fold forms a vacuole inside Phagocytosis- engulfs large particles (type of endocytosis) Pinocytosis- pinching of liquid pockets to form vacuoles |
