which of the following is the smallest? ribosome,atom,tissue,bacteria cell
atom
Whats the function of the cell membrane
It controls what enters and leaves the cell
true or false diffusion is a form of active transport
False diffusion is a passive process
whats a nucleic acids
molecules that store and transmit genetic info
what is the cell cycle
the continuous process of a cell growing and dividing, includes inter phase mitosis and cytokinesis
what is the control center of the cell
the nucleus
what is the major difference between plants and animals cells
plant cells have a rigid cell wall and chloroplast, which animal cells lack
whats facilitated diffusion
a type of passive transport where particles move across the membrane with the help of transport proteins
what are macro-molecules
large molecules essential for life, composed of smaller sub units called monomers that link to form polymers
which phase is the longest in the cell cycle
interphase
what type of cell has a cell wall
plant cells
Firm, protective structure that gives the cell its shape in plants and bacteria
the cell wall
what effect does solute have on the water potential within a cell
water potential becomes more negative
examples of lipids
fats for energy, phospholipids for cell membranes
what is the G0 phase in the cell cycle
a resting state where a cell is not preparing to divide
What organelle makes proteins?
The ribosome
whats the function of a vacuole
it stores water,food,waste, and other materiel's
whats the definition of diffusion?
the movement of particles from an area of higher concentrations to an area of lower concentration?
4 main types of macromolcules
carbohydrates,lipids proteins and nucleic acids
mains phases of the cell cycle
interphase mitosis and cytokinesis
What is the difference between a prokaryotic and eukaryotic cell?
eukaryotic cells have a nucleus and other membrane-bound organelles, while prokaryotic cells do not
what is the difference between the Rough ER and smooth ER
the rough ER has ribosomes and makes proteins while smooth ER does not have ribosomes and is involved in making lipids
what is osmosis
the diffusion of water across a selectively permeable membrane from an area of higher water concentration to an area of lower water concentration
what macaroni fights diseases
proteins
whats the g1 checkpoint primary function
to determine if the cell should commit to dividing, or if it should enter the GO phase instead
