biology definitions Flashcards
Eukaryotic cell
Contains DNA in the nucleus
what is a cell?
Smallest living part, structure of life
Nucleus
Controls the activities in the cell
Cytoplasm
Most chemical reactions take place
cell membrane
Controls what goes in and out of the cell
Mitochondria
where aerobic respiration takes place, releases energy for the cell to use
ribosomes
site of protein synthesis (where protein is made )
substance that makes up plant walls
cellulose
cell wall
provides the support and strengthens the cell
chloroplasts
absorbs light for photosynthesis and contains chlorophyll
permanent vacuole
stores sap, keeps plant cells rigid to provide support
difference between prokaryotes and eukaryotes
P has a nucleus E does not
difference between animal and plant cells
Plants have : chloroplasts, permeant vacuole and cellulose cell wall
organism that is prokaryotes
Bacteria
Prokaryotes have a cell wall. True or false?
True
extra layer on bacteria
slime capsule
genetic material of Prokaryotes
cytoplasm
Difference between Prokaryotic and Eukaryotic DNA
Prokaryotic= circular Eukaryotic= Linear
small DNA rings found in prokaryotes
Plasmid
function of flagella
To allow cells to swim and move around
difference between animal cells and bacteria
A= No cell wall and linear DNA
P= Cell wall and circular DNA
similarity between plant and bacterial cells
Both have cell walls
equation that links magnification, image size and actual size
image size = Actual size x magnification
