homeostasis
the regulation of an internal environment (despite external conditions) to optimize life processes
Growth and Development
an organism growing and developing through out their life
response to stimuli
an organism responds immediately to their surroundings
reproduction
an organism lives long enough to be able to reproduce
evolution
over time organisms evolve to be able to adapt to their surroundings
cell
all living things have cells
metabolism
the burning of food to create energy
prokaryote
organism with no nucleus or bound organelles
eukaryote
organisms that typically multicellular that contain a nucleus and bound organelles
unicellular
organism with one cell
multicellular
organism with multiple cells
cell theory
All living organisms are composed of one or more cells
Cells are the basic unit of life (structure and function)
Cells come from the reproduction of existing cells
nucleus
stores genetic information and helps with production of ribosomes
DNA
genetic material
biotic
something that is living
abiotic
something that is not living
cytoplasm
environment where chemical reactions occur
cell membrane
serves as a boundary between cell and external environment, also controls movement in and out of the cell
ribosomes
in the cytoplasm unattached to membranes to produce proteins that function within cytoplasm
structure and function
the structure of an organism follows a specific function
interdependence
organisms that are dependent on each other
energy flow
the movement of energy around an ecosystem
inheritance
process by which DNA is passed down to offspring
compound light microscope
a microscope that uses two different types of lens
objective lens
high powered magnifying glass that focuses on specimen
diaphragm
controls the amount of light that shines through
stage
where the slides of specimen goes
organelle
sub-cellular structure with specific jobs to preform in the cell
ocular lens
eyepiece of the microscope which magnifies the image
tissue
a group of cells with similar structure that function as a unit
organ system
a system consisting of multiple organs
organism
a living thing
golgi apparatus
modifies and sorts proteins and lipids (warehouse)
lysosome
filled with enzymes that digest substances such as food particles, damaged organelles, or microbes (trash compacter)
rough ER
involved in the production of proteins that will either become a part of the cell membrane or be released into the cell
smooth ER
involved in the production of lipids that will either become a part of the cell membrane or be released into the cell
vesicle
carries proteins, lipids, and waste from the golgi apparatus to other cell compartments or outside the cell membrane (transport systems)
diffusion
he movement of molecules from an area of high concentration to an area of low diffusion
facilitated diffusion
when larger or polar molecules use proteins (channel or carrier protein) to help them across the cell membrane
osmosis
diffusion of water
concentration gradient
concentration gradient is the difference in concentration between two sides of an area or boundary
hypotonic
lower concentration of solute
hypertonic
higher concentration of solute
isotonic
equal concentration of solute
active transport
transport that requires energy (ATP) to occur
endocytosis
movement of big particles into the cell membrane using vesicles
exocytosis
movement of big particles out of the cell membrane using vesicles
phosophlipid
functions at separating cells from the environment because the hydrophobic (non-polar) tail structure won't let polar substances in (fat and water don't mix)
polar
charged ions (unevenly distributed)
nonpolar
not charged ions (evenly distributed)
chloroplast
during photosynthesis, uses sun's energy, water, and carbon dioxide to produce sugars and oxygen
mitochondria
power house of the cell, uses cellular respiration in sugar to produce ATP
