7 Characteristics of Life
Cell Membranes
Active/Passive Transport
Organelles
Classification/Osmosis
100
The smallest unit of living things
What is a cell?
100
This causes the membrane to be strong and less flexible.
What is cholesterol?
100
The movement of molecules from an area of high concentration to low concentration.
What is diffusion?
100
These are four common features of both prokaryotes and eukaryotes
What are genetic material, cell membrane, cytoplasm, ribosomes?
100
The Six Kingdoms
What is animalia, plantae, fungi, protista, archae, bacteria?
200
The regulation of variables that maintain internal conditions so that they are stable and constant
What is homeostasis?
200
A characteristic of the membrane that means that some molecules can pass through, but not others.
What is selective permeability?
200
Diffusion continues until this state is reached where the concentration gradient is zero, but molecules are still moving back and forth across the membrane.
What is dynamic equilibrium?
200
The three points of the cell theory
What is 1) all living things are composed of cells, 2) cells are the basic unit of structure/function in organisms, 3) cells only come from the reproduction of existing cells?
200
The first name and the second name of any organism
What is genus and species?
300
The most basic form of energy used by all organisms.
What is ATP?
300
The description of all the components of the cell membrane: proteins that move about in the membrane along with other molecules such as cholesterol, carbohydrates, etc. making up a bunch of tiny different "pieces" coming together to make a whole membrane.
What is fluid mosaic model?
300
The two kinds of transport proteins
What is channel proteins and carrier proteins?
300
These are only found in plant cells and they provide turgor pressure for the plant
What is the central vacuole?
300
The two-word naming system for organisms
What is binomial nomenclature?
400
This is how living things increase in size.
What is cell division or cell enlargement?
400
Two functions of the cell membrane.
What is 1) isolate cell contents from the outside, 2) regulate exchange of materials 3) communication with other cells?
400
These are characteristics of molecules that are able to enter cells through simple diffusion.
What are small, hydrophobic molecules?
400
Microfilaments, intermediate filaments, and microtubules are all examples of this
What is the cytoskeleton?
400
In this situation, a solution has a higher concentration of water than the cell and the water will move into the cell.
What is hypotonic?
500
The source of all variations that cause evolution to occur in organisms.
What are mutations?
500
These proteins serve as an ID tag for the cell.
What recognition proteins?
500
Protein-assisted active transport proteins have these two binding sites.
What are binding site for the molecule being moved and a binding site for ATP?
500
These are the three possible destinations of a vesicle leaving the Golgi Complex.
What is a lysosome, to be secreted by exocytosis, to merge with the plasma membrane?
500
If a cell has a higher solute concentration inside than its solution's solute concentration, the solution is said to be this.
What is hypotonic?
