Anatomy quiz 2

Cell divison

QuestionAnswer
Cell Cycle Definition A series of changes the cell experiences from the time it is formed until it divides.
Cell Cycles (2) phases: Interphase, Mitosis
Interphase Def: Genetic material (DNA) within the cell is replicated Cell Grows and carries metabolic processes (G1, S, G2) 90%
Interphase Phases "Between divisons" G1: Cell Growth and active prep for cell divison S: Nuclear material (DNA) is replicated G2: Prep for mitosis 90% of cell cycle spent in interphase
Cell Divison 10% Mitosis: Nuclear divison--> PMAT Cytokinesis: divison of cytoplasm (begins after mitosis is nearly complete
Mitosis def: Nuclear divison (PMAT)
Cytokinesis def: The divison of Cytoplasm -begins after mitosis is nearly complete
Prophase: No nuclear envelope; chromosomes visable
Metaphase: Chromosomes aligned in middle
Anaphase: Chromosomes seperated and pulled to opposite ends
Telophase: Cell membrane grows between newly split chromosomes
Cytokinesis: Divides cytoplasm
End of Mitosis: 2 genetically identical daughter cells
Plasma Membrane is ____ barier Selectively permeable * hence passive and active transport
Passive transport: No energy (ATP) required
Examples of Passive transport: Diffusion and Osmosis
Diffusion: PASSIVE Down concentration gradient: HIGH TO LOW (spread out)
Molecules will diffuse when: -Small molecule pass through membrane pores -The molecules are lipid-soluble -The molecules are assisted by a membrane carrier (spread eagle)
Diffuse rates are affected by: SIZE AND TEMP -The SMALLER the molecules the FASTER the rate of diffusion -The WARMER the molecule the FASER the rate of diffusion (Smaller and Warmer=Faster)
Osmosis PASSIVE Water moves down concentration gradient HIGH water concentration to LOW water concentration -water movement across the cell membrane is affected by solute concentration -isotonic, hypotonic, hypertonic
Isotonic: = Have the same solute and water concentration as cells and cause no visible changes
Hypertonic: -Contains MORE solutes than the cells do -the cell shrinks
Hypotonic: Contains FEWER solutes (more water) than the cells do -cell wall plumps/expands
Active Transport -ATP required: cells provide metabolic energy ex: sodium potassium pump
Sodium-Potassium Pump: Transport (3) sodium ions (Na+) out of the cell and (2) Potassium (K=) into the Cell using Energy

Use these flashcards to help memorize information. Look at the large card and try to recall what is on the other side. Then click the card to flip it. If you knew the answer, click the green Know box. Otherwise, click the red Don't know box.

When you've placed seven or more cards in the Don't know box, click "retry" to try those cards again.

If you've accidentally put the card in the wrong box, just click on the card to take it out of the box.

You can also use your keyboard to move the cards as follows:

If you are logged in to your account, this website will remember which cards you know and don't know so that they are in the same box the next time you log in.

When you need a break, try one of the other activities listed below the flashcards like Matching, Snowman, or Hungry Bug. Although it may feel like you're playing a game, your brain is still making more connections with the information to help you out.

To see how well you know the information, try the Quiz or Test activity.
