A
All living things are made of cells
All cells come from preexisting cells
Cells perform the functions of living things
These are the three parts of what?
Cell theory
A group of similar cells that work together
tissue
means "little organ"
membrane-bound structures that perform special functions
organelle
surrounds all cells and regulates what comes in and out of the cell. semi-permeable
cell membrane
whip-like structure some cells use to propel themselves through an environment
flagella
This contains important information for making proteins and plays a role in regulating many cellular processes
DNA
A network of tubes that help produce and transport proteins or other molecules through the cell. It can be rough or smooth.
Endoplasmic reticulum
Many proteins made in the ER are sent to this organelle. It modifies many of these proteins and packages them into vesicles, small bubble-like structures that transport the proteins to the final destinations. (the post office)
Golgi apparatus or Golgi body
Small structures that assemble proteins. These can also be found on rough ER
ribosomes
"The powerhouse of the cell" This organelle makes most of the cell's ATP, which is used to power cellular processes.
Mitochondria
This term means that it allows some substances to pass through but keeps others out.
semi-permeable
This type of transport does not require work or energy and diffusion and osmosis are examples
passive
This type of transport does require work (or energy)
active
A living thing capable of making its own energy
producer
a living thing that must get energy from a different source
consumer
movement of molecules through a membrane
diffusion
The diffusion of water
osmosis
The process of obtaining energy from the sun
photosynthesis
Sunlight enters the chloroplasts and is absorbed the the green pigment called
chlorophyll
The energy currency used to power active transport (3 letters)
ATP
A process that does not require oxygen
anerobic
A group of cells creates tissue, and a group of tissues works together to create an...
organ
A small organelle in eukaryotic cells that acts as the demolition crew within the cell
lysosome
A protein that speeds up or slows down chemical reactions
enzyme
When a certain type of molecule is more densely packed on one side of the membrane than on the other.
concentration gradient
