Intro to cells
What is the smallest unit of structure and function in living things?
A cell
Look at your paper sheet. Which number is the mitochondria?
Number 6
The _____ bilayer makes up the cell membrane.
phospholipid
You put sugar in a glass of water.
What is the solute? What is the solvent?
Solute: Sugar
Solvent: Water
What organelle digests food and breaks things down in your cells?
Lysosome
What scientist discovered cells in DEAD cork material?
Look at your paper sheet. Which number organelle controls what goes in and out of the cell?
1 (cell membrane)
What type of transport (passive or active) does not require ATP?
Passive
ATP is usable energy
What are the three types of osmotic solutions?
Hypertonic, hypotonic, isotonic
What organelle makes proteins?
Ribosome
A structure within a cell that performs a specific function is called a/an _____.
organelle
Look at your paper sheet. Which number is pointing to the rough ER where proteins are modified?
Number 3 (Rough means ribosomes on surface)
What type of transport moves water molecules across the cell membrane?
Osmosis
A cell has a higher sodium content than the solution it is sitting in.
What type of solution would this be?
hypotonic solution
solution has less sodium compared to the cell, therefore HYPOtonic solution
Name 2 organelles that are ONLY found in plant cells.
chloroplast
cell wall
central vacuole
What type of cell (Prokaryotic or Eukaryotic) is a plant cell?
Eukaryotic
Look at your paper sheet. In what NUMBER organelle does photosynthesis occur?
Number 11 (chloroplast)
What type of transport (active or passive) moves particles from LOW to HIGH concentration?
Active
*uses energy to go "up the slide" from low to high
A cell is placed into a really salty solution (saltier than the cytosol in the cell). Will the cell shrivel up or will it burst?
Shrivel up
Water will go from HIGH concentration of water to LOW concentration of water, water will leave the cell to equalize the ratio of sodium to water on the outside of the cell
What organelle makes lipids for the cell membrane?
Smooth ER
What type of cell (Prokaryotic or Eukaryotic) has a DNA bundle with NO nucleus?
Prokaryotic
Look at your paper sheet. In which number organelle are ribosomes made? (Look closely)
What type of passive transport uses integral proteins like channel proteins to move things across the cell membrane?
Facilitated diffusion
Which type of solution means there will be no net movement of water?
isotonic solution
What is the term for everything inside the cell except for the nucleus?
Cytoplasm
