Cards

Term
endoplasmic reticulum
Definition

exports proteins

where lipid components of cell membrane are formed

Term
chromoplasts
Definition

type of plastid

stores pigment that makes plants appear a color

Term
vacuoles
Definition
structure that stores proteins
Term
nucleus
Definition
control center of cell
Term
centrioles
Definition
cell division
Term
cell membrane
Definition
regulates what comes in & out
Term
ribosomes
Definition
particles of RNA and protein in the cytoplasm
Term
cell wall
Definition
supports cell
Term
chloroplasts
Definition
uses energy from sunlight to make energy
Term
mitochondria
Definition
converts energy, powerhouse
Term
lecuoplasts
Definition
stores starch 
Term
lysosome 
Definition

filled with enzymes that break down food

into particles that can  be used

Term
chromosome 
Definition
contains DNA that is passed down generations
Term
nucleolus 
Definition
makes ribosomes
Term
golgi bodies
Definition
packages and ships proteins
Term

4 ways that plant cells are different

from animal cells

Definition

animals have centrioles

plants have plastids

animals don't have a cell wall

plants have chloroplasts 

Term

what is a prokaryote?

give examples

what is a eukaryote?

give examples

Definition

prokaryote=no nucleus;bacteria

eukaryote=nucleus; animals, plants

Term

3 organelles that prokaryotes 

and eukaryotes have in

common

Definition

DNA

cell membrane 

ribosomes

Term

5 differences between 

prokaryotes 

and eukaryotes

 

Definition

eukaryote has a nucleus

eukaryote have double membrane bound organelles

eukaryotes are complex

eukaryotes' ribosomes are larger and more complex

eukaryotes are generally larger

Term
active transport
Definition

particles move from where its less 

concentrated to where its more

concentrated. uses energy.

Term
passive transport
Definition

doesn't use energy, passing of

substances through a semi-

permeable membrane

Term
diffusion
Definition

particles move from where its more

concentrated to where its less concentrated.

doesn't use energy.

Term
osmosis
Definition

diffusion of water through a

semipermeable membrane

Term
endocytosis
Definition

taking material into cell through pockets

of cell membrane

pockets break off

which forms vacuoles within cytoplasm

Term
exocytosis
Definition

membrane of vacuole fuses with cell 

membrane forces contents out

of cell

Term
hypetonic
Definition

concentration outside is smaller

than inside

Term
hypotonic
Definition

concentration outside and 

inside is equal

Term
isotonic
Definition

concentration outside

and inside is equal

Term
selectively permeable
Definition
only some substances can pass through
Term
order of mitosis phases
Definition

cytokensis

interphase

prophase

metaphase

anaphase

telophase

Term
cytokensis
Definition

division of cell

cytoplasm pinches in half

each daughter cell has an indentical set of chromosomes

Term
interphase
Definition

cell grows

replicates DNA and centrioles

Term
prophase
Definition

chromatin go into chromosomes

centrioles seperate

spindle forms

nuclear envelope breaks down

Term
metaphase
Definition

chromosomes line up in the middle of cell

chromosome is connected to spindle at centromere 

Term
anaphase
Definition
chromatids split into chromosomes and move apart
Term
telophase
Definition

chromosomes gather at opp. ends

and lose their shapes

2 new nuclear envelopes form

Term

how many and which types of cells

are produced from mitosis?

Definition

2 cells are there from each division

and eukaryotic 

Term
why is mitosis necessary?
Definition
to help us grow and repair
Term

what type of reproduction is

mitosis used for?

Definition
asexual
Term
archaraebacteria
Definition

means ancient bacteria

heterotrophic

no oxygen or sun

very high heat

asexual

Term
eubacteria
Definition

meaning true bacteria

normal conditions

hetertrophic

feed on plants

asexual

Term
protista
Definition

eukaryotic

unicellular

live in water or soil

 

Term
fungi
Definition

have cell walls

eukaryotic

unicelluar

heterotrophic

examples; decomposers, parasites

Term
plantae
Definition

eukaryotic 

multicelluar

cell wall

sexual

autotrophic
