Cell Theory
A type of organism composed of a single cell.
What is a unicellular organism?
An example of this is thermoregulation and blood sugar regulation
What is a negative feedback loop?
The two reasons why cells undergo mitotic cell division
What is growth and repair?
The structure responsible for moving chromosomes to opposite sides of the cell.
What are spindle fibers?
The hormone released by the pancreas to tell the liver to remove glucose from the blood.
What is insulin?
An analogy for this is a home air conditioner and heater. Both are used to maintain a set temperature.
What is Homeostasis? (2x points if said in an accent)
The term used to describe how the cell membrane is "picky", only allowing some molecules to move in and out of the cell
What is selectively permeable?
The stem cell type that is partially differentiated.
What are Adult stem cells?
The phase of mitosis when chromosomes condense from chromatin.
What is Prophase?
The hormone released by the pancreas to tell the liver to break down stored glycogen and release it into the blood.
What is glucagon?
These "mini organs" work together to maintain homeostasis inside the cell.
A main difference between Eukaryotic cells and Prokaryotic cells.
What are membrane-bound organelles?
The three characteristics that allow a molecule to EASILY pass through a cell membrane.
What is being small, nonpolar and uncharged?
The cellular process that helps regular helps carve out our fingers and toes.
(...maybe if this didn't happen, we could swim as fast as Michael Phelps)
What is apoptosis?
This phase of mitosis has an M-plate
What is metaphase?
Cells spend 95% of their time in this part of the cell cycle
What is Interphase?
All cells have these 4 things
What is Genetic material (DNA or RNA), Cytoplasm, Cell membrane, Ribosomes?
The main type of molecule moved across the membrane through a protein pump up the concentration gradient.
What are charged particles?
(Examples: potassium K+, chlorine (Cl-), Sodium (Na+)
The term for Cancer-causing agents that cause cancer by mutating DNA
What are carcinogens?
In plants, during cytokinesis, the cell plate will become this structure.
What is the cell wall?
STORY TIME:
"You're at a hospital and the new nurse accidentally put distilled water into your veins instead of saline (contains water + solute) when setting up your IV. The resulting tonicity inside of the blood cells are...
What is hypertonic?
(Hint: Eukaryotic cells have cell walls made out of cellulose)
What is peptidoglycan?
This term means "cell drinking".
When cells engulf liquids into vesicles and digests them.
What is pinocytosis?
This type of tumor can metastasize
What is a malignant tumor?
Cells can't just get bigger to grow; they have to stay small to maintain a high...
What is a surface-area-to-volume ratio?
Catecholamines are neurotransmitters that increase alertness, motivation and focus. According to Dr. Huberman, doing one of these things can help increase the amount of catecholamines produced in your body.
What is Cold Exposure?
