The diffusion of water across a (a)
What is osmosis?
Process of taking liquids into a cell and surrounding it in a vesicle
the diffusion of water across a permeable membrane
molecules being 'forced' across the cell membrane from low to high
diffusion of molecules across the cell membrane using transport proteins
Osmosis:
moves from high to low
moves from low to high
is active (requires ATP)
is passive (no ATP)
Hypotonic solutions:
are 2 solutions having an = concentration
a less concentrated solution
a more concentrated solution
water > solution
solution > water
Hypertonic solutions are (a) concentrated.
Passive transport move...
low to high
up the concentration gradient
high to low
movement of (NA+, CI-, K+)
Active transport includes
low to high transport
molecules moving down the concentration gradient
energy that is needed (ATP)
molecules moving up the concentration gradient
Endocytosis includes...
using a vesicle to take things INTO the cell
passive transport
using vesicles to take things OUT of the cell
active transport
Exocytosis is:
the process of taking liquids into a cell, surrounding it in a vesicle.
diffusion of molecules across the membrane using transport proteins.
the diffusion of water across a permeable membrane.
release of substances out of a cell by the fusion oof a vesicle with the cell membrane.
Facilitated diffusion uses ________ ________.
(a)
Prokaryotes are....
multicellular
have no nucleus
contains organelles
unicellular
Eukaryotes include...
no nucleus, no organelles
free-floating DNA
a nucleus, organelles, and DNA in the nucleus
bacteria, algae
What is gene expression
process where a gene turns into a cell to create RNA + protiens
process young cells mature + take their developed formation
process where materials float around the cell
process that includes a vesicle
G1 - cell growth
cell grows in size
cell shrinks and begins to split
increase of production in RNA, proteins, and organelles
focused on replicating all DNA
S phase - DNA synthetization
nuclear membrane breaks
prep for last phase
focus on replicating all DNA
creates sister chromatids, attaching at the centromere
G2 phase - preperation for cell division
creates 2 identical daughter cells
continues to grow, prep for last phase
continues synthesizing protiens
focus on replicating all DNA
The order of mitosis:
metaphase, cytokinesis, telophase, anaphase, prophase
telophase, anaphase, prophase, cytokinesis, metaphase
prophase, metaphase, anaphase, telophase, cytokineses
prophase, metaphase, anaphase, cytokinesis, telophase

True
False
Facilitated diffusion is:
active transport (requires ATP)
endocytosis
passive transport (no ATP required)
mitosis
Cytokinesis is the division of the (a) .
Interphase is the....
first 5 stages of cell cycle
first 2 stages of cell cycle
first 4 stages of cell cycle
