Units of life
Does a prokaryote have a nucleus?
No, its a pro so it doesn't need it
Name the first found virus?
Tobacco mosaic virus (TMV)
What is the thick layer outside of a plant cell?
Cell Wall
Hypertonic
Water leaves and cell shrinks
What is the function of plasma membranes?
TRANSPORT
Name some of the differences between cellular respiration and photosynthesis?
Plants vs animals
Food is broken (burned) down to water and carbon dioxide and exhaled and Oxygen is required
Plants its the opposite, require energy, carbon dioxide, and water to convert to energy
What is phagocytosis?
Cell eating
Show thingy on board, hydrophobic and hydrophilic
Plasma mebrane protects, PASSES STUFF THROUGH IT (water and proteings through channel)
What part of the cell has a phospholipid bilayer?
Plasma Membrane
What is active transport?
Takes energy and moves molecules "against the grain"
What is the outside layer of a cell?
Plasma Membrane
Hypotonic
Water enters and cell volume increase
Does a eukaryote have a nucleus and give me an example.
Yes-humans, animals, fungi, plants
What's the difference between organic and inorganic molecules?
Carbon-based organic, everything else is inorganic
What is passive transport?
Moves molecules with the flow/ with the grain
What does rough ER have more than smooth ER?
Ribosomes
What is tonicity (hint:liquid)
how a liquid effects a cell's volume
What would happen if a cell was suspended in salt water?
hypertonic-shrinks
What is plants wilting an example of (tonicity)
hypotonic
... is the movement of something from high concentration to a lower concentration to even out
Diffusion, concentration gradient is the type of potential energy used to make diffusion so he'd also probably take that, osmosis also works
Why can't we have large unicellular organisms?
Surface Area
Name the three types of unicellular organisims.
Bacteria, Archea, and Protists (BAP)
Label the cell (cytoplasm, nucleus, plasma membrane, and ribosomes)
On board
Why do mitochondria have their own DNA and organelles within themselves?
Endosymbiosis!!!!!
What does selectively permeable mean?
That membranes can choose what molecules that want to pass through onto the cell
