Cells
The 3 principles of Cell Theory are
What is:
Cells come from pre-existing cells
Cells are the basic unit of life
All living things are made of cells
A solution is composed of?
Solute and Solvent
The first stage of the Cell Cycle?
Interphase
What amphipathic molecule can be found in the cell membrane
Phospholipids
The difference between prokaryotic eukaryotic cells
Prokaryotic cells lack a nucleus
Solution with higher concentration of dissolved solutes relative to a cell or system.
Stage where spindle fibers attach to centromeres of duplicated chromosomes?
Metaphase
Difference between simple diffusion and facilitated diffusion?
Facilitated diffusion uses a transport protein to cross molecule across cell membrane
How does an animal cell differ from a plant cell?
Cell Wall
Small or no vacuole
no chloroplasts
flagella
True or False:
Hypotonic Solutions cause cells to shrink
False: The cell will swell
What would a plant cell form before cytokinesis?
Cell Plate
A person is found to have a defect in his ATP synthase gene. What type of transport will be prevented from taking place?
Active Transport
All cells contain?
Cell Membrane
Ribosomes
DNA/RNA
Cytoplasm
A red blood cell is placed in a hypotonic solution. Describe the net movement of water
Water will flow out of the cell causing it to shrink
Which phase of mitosis is characterized by the reappearance of the nuclear envelope?
Telophase
True or False:
A researcher observes that a molecule is brought inside the cell via membrane transporters. The researcher concludes that this transport must solely by a form of active transport.
False, can also be passive transport (facilitated diffusion/osmosis)
Organelle found in animal cells only that contain enzymes to breakdown waste AND performs apoptosis.
Lysosomes
An egg is placed in a hypertonic solution, what are two possible outcomes?
The egg may lose mass and volume
A scientist has discovered a mutation that prevents cells from continuing after metaphase of mitosis. Which is the most likely target of the mutation?
Spindle Fiber formation from centrioles
What are the three examples of active transport?
Molecular Pumps (Na-K Pumps)
Endocytosis
Exocytosis
