|
|
|
|
eukaryotes
|
cells that contain nuclei
|
|
|
|
nucleus
|
a large membrane-enclosed structure that contains the cells genetic material in the form of DNA
|
|
|
|
cell theory
|
new cells can be produced by only from existing cells
|
|
|
|
cells
|
basic unit of life
|
|
|
|
chromosomes
|
threadlike structures contain the genetic information that passes from one generation of cells to the next
|
|
|
|
nucleolus
|
where the assembly of ribosomes begins
|
|
|
|
ribosomes
|
proteins are assembled
|
|
|
|
endoplasmic reticulum
|
site where lipid components of the cell membrane assembled along with proteins and other materials are exported from the cell
|
|
|
|
golgi apparatus
|
modify,sort,and package proteins and other material
|
|
|
|
lysosomes
|
get rid of all the bacteria and break it down and digest it
|
|
|
|
vacuoles
|
is to store proteins
|
|
|
|
mitochondria
|
coverts chemical energy into energy that the cell can use
|
|
|
|
chloroplasts
|
capture energy from sunlight into energy the cell can use
|
|
|
|
cytoskeleton
|
provides strength and support to the cell
|
|
|
|
centrioles
|
help organize cell division
|
|
|
|
cell membrane
|
thin flexible barrier-regulate what enters and leaves the cell
|
|
|
|
cell wall
|
strong supporting layer around the cell membrane
|
|
|
|
lipid bilayer
|
a double layered sheet
|
|
|
|
concentration
|
is the mass of solute in a given volume or solution
|
|
|
|
diffusion
|
particles move away from an area where they are less concentrated
|
|
|
|
osmosis
|
the diffusion of water through a selectively permeable membrane
|
|
|
|
isotonic
|
the concentration is equal on both sides, "same strength"
|
|
|
|
hypertonic
|
the more concentrated sugar solution was HYPERTONIC which means "above strength"
|
hyper = more - above
|
|
|
hypotonic
|
the dilute sugar solution was hypotonic, or "below strength"
|
hypOtonic - O = H2O - if you add water to something it makes it not full strength - below strength
|
|
|
facilitated diffusion
|
when the channels are used to help the material into or out of the cell
|
|
|
|
active transport
|
when the cell has to use energy to move the molecule
|
|
|
|
endocytosis
|
the process of taking material into the cell by mean of unfolding and pockets of the cell membrane
|
|
|
|
pinocytosis
|
cell eating
|
|
|
|
exocytosis
|
reassessment of large amounts of material
|
|
|
|
cell specialization
|
develop different ways to perform different tasks
|
|
|
|
tissue
|
similar cell grouped into units
|
|
|
|
organ
|
many groups of tissues that work together
|
|
|
|
organ system
|
a group of organs that work together to perform specific function
|
