living creature; mechanism, has a system of interdependent parts
combination of related things or parts that form a complex whole; body of an animal or human considered as a whole; set of principles or ideas; method, procedure; organization, orderliness
a grouping of tissues into a distinct structure, as aheart or kidney in animals or a leaf or stamen in plants, thatperforms a specialized task
an aggregate of similar cells and cell productsforming a definite kind of structural material with a specificfunction, in a multicellular organism
A usually microscopic structure containing nuclear and cytoplasmic material enclosed by a semi permeable membrane and, in plants, a cell wall; the basic structural unit of all organisms
a part of a cell that performs the functions of human organ(s) in a cell
only lets certain things through because of gap sizes
The process of particles (gases and liquids) moving from a high concentration to a lower concentration (can diffuse in gases, liquids, and SOME solids) with a permeable membrane
when water diffuses (usually in the context of a semi permeable membrane)
Example: There are two containers, one is full of a 15% solution of sugar and water, the other is full of a 30% solution of sugar. Both containers are connected, and there is a semi permeable membrane between them that does not allow sugar through. The water from the 15% solution will move to the 30% solution to lower the concentration of sugar in one and make the concentration of sugar bigger in the other until they are both the same concentration.
the part of the solution in which the solute is being dissolved (more of)
(WATER = universal solvent that dissolves most things solubility depends on temperature)
the part of the solution that is dissolving in the solvent (less of)
homogeneous (evenly spread out) mixture of a solvent and a solute
a higher concentration of particles
a lower concentration of particles
It was proposed/established as a result of the invention the microscope. First cell examined was a cork tree → named them cells. The theory is that cells make up all living things → unit of life. Cells can be organisms unto themselves—unicellular organisms OR they can be a part of a multicellular organism. Cells come from pre-existing cells → mitosis and meiosis. Before... they thought that something could come from nothing AKA spontaneous generation.
It is semi permeable membrane that takes in and releases oxygen through diffusion in cellular respiration
It is only found in plant cells. They receives waste from a secretory vesicle, then the food and contractile vacuoles get rid of solid and liquid waste respectively. The liquid waste exits the cell through diffusion.
They perform cellular respiration, the act of converting glucose to ATP, carbon dioxide, and water. They each have a double membrane, and the inner membrane has many folds to create more surface to perform Cellular Respiration.
It is a semi permeable, filtering, protective barrier made from polysaccharides, cellulose specifically in larger plants, that is only found in plant cells.
They go to opposite sides of the cell while they help in separating the replicated DNA in Mitosis and Meiosis.
It has a double membrane that encloses DNA that determines what the cell or the organism it is a part of will become .
They are only found in plant cells, contain chlorophyll, and are where the photosynthesis takes place.
Amino acids are synthesized into proteins with instructions from mRNA in the ribosomes. Ribosomes are often located the rough endoplasmic reticulum, but they can float loosely through the cell.
A set system of tiny tubes that move nutrients and other things throughout the cell. The smooth one stores ions and steroids for rapid access, and the rough one packages proteins into transition vesicles with the help of Ribosomes.
They produce enzymes the cell needs to digest ATP, and they also create enzymes that will eventually break the cell down if there is no food for the cell.
A soupy mixture primarily made up of water and secondarily made up of proteins and minerals. All organelles but the cell membrane are contained in this.
Golgi Complex (Golgi Bodies, Golgi Apparatus)
It has only one membrane and looks like a stack of pancakes. It gathers many simple molecules and combines them to make them more complex. They receive transition vesicles, change the proteins, and then send out the more complex proteins, lysozomes, out into the cytosol until needed.
6H2O + 6CO2+ Sunlight → C6H12O6+ 6O2
C6H12O6 + 6O2 → 6CO2 + 6H2O + Energy (as ATP)
Thin layer around the earth, all environments on earth w/ organisms
A group of organsims + their physical environment
group of organisms of the same species in a community
the number of individuals of the same species in an area
environmental elements that stabilize population size (amount of food available, hunters, illness, and drought)
All of the different populations that live in an area
(once) living organisms
Never living organisms
organisms that live on/in host → harms them
one of the organisms that live together benefits; no benefit or harm to the other
both organisms that live together benefit
bacteria in our digestive tract
keeps us with regular bowel movements, we don't digest it, and we need it daily
a large region defined by climate and species that live there
when 2+ elements physically mix → each retains their own properties
when 2+ elements chemically mix → don't retain properties
mixture of 2+ metals
the breaking down in living organisms ofmore complex substances into simpler ones, with the release of energy →A destructive metabolism
constructive metabolism; the synthesis in living organisms of morecomplex substances from simpler ones
Xylem + Phloem
cells that conduct water and glucose in trees and bushes
put things together
the extent to which a given measurement agrees with the standard value
How close to the actual measurement a measurement is
amount of Matter an object has
the force of gravitational pull on an object
how much space an object takes up (m3, cm3, mL, L)
D=M/V (D= Mass/Volume)
Has a true Nucleus + membrane bound organelles
No true Nucleus + no membrane bound organelles
An organism, especially a fungus or bacterium, that grows on and derives its nourishment from dead or decaying organic matter.
