An organism made up of only one cell
An organism made up of more than one cell
The outer layer of plant, bacteria and fungi cells.
- The selectively permeable boundary layer of cells.
- Made of a lipid bilayer .
- Hydrophilic ends and hydrophobic center.
Contains and circulates organelles.
Control center of the cell which contains genetic material and is bound by a double membrane.
Genetic material inside the nucleus.
Have cell walls made of cellulose
Have cell walls made of peptidoglycan
- Made of protein and carbohydrates.
- Forms bacteria cell walls.
Have cell walls made of chitin
Polysaccharide that forms fungi cell walls
- The inside of a cell membrane is aqueous
- Allows some things through, and for some it doesn't .
- Ex. The cell Membrane
Material moving from high to low concentration, or with/down the concentration
Hydrophobic material must pass through the proteins in a cell membrane.
The cell must use energy to move material from low to high concentration.
- The cell needs to take in a large items so it engulfs it.
- A vesicle forms to transport the items into the cell.
Bulk transport into the cell.
Bulk transport out of the cell.
A pocket formed to transport material during bulk transport.
- The movement of water down the concentration gradient across a membrane.
- Water cannot go through the membrane because it is, obviously, hydrophilic.
- So water goes across the cell membrane through facilitated diffusion.
- More particles outside the cell. ie: salt
- Less Water outside the cell.
- Causes water to leave the cell, and the cell shrivels up and dies.
- Less Particles outside the cell. ie: salt.
- More water outside the cell.
- Causes the cell to swell and burst.
Perfectly balanced concentrations inside and out of the cell.
Having membrane bound organelles.
A cell that dose not have membrane bound organelles.
Organelle for storage of wastes and other material.
Sites of Protein synthesis; not bound by a membrane.
Smooth Endoplasmic reticulum
System of membrane and tubes that transports substances around the cell.
Rough Endoplasmic reticulum
- Endoplasmic reticulum with ribosomes bound to it.
- Ribosomes on the rough ER specifically synthesize, membrane proteins like channels, or secreted proteins.
Sorts and packages proteins made by ribosomes on rough ER.
- Function in cellular respiration.
- Produce ATP for the cell.
- Bound by double membrane.
Digest foreign substances and worn-out organelles.
Help to form spindle fibers during mitosis.
- Control center of the cell.
- Contains genetic material (DNA).
- Bound by a double membrane.
- Small, dense structure in the nucleus.
- Site of ribosome synthesis.
A protein used to break down substances.
- A substance that makes a chemical reaction occur faster.
- An enzyme.
The places where the reactants bind to the enzyme.
- Reactants in an enzyme-catalyzed reaction.
- The thing being broken down.
- An enzyme loses its shape.
- Can be cause from heat.
Molecules that help enzymes work faster, and sometimes they are necessary for a reaction to occur.
- Vitamins a coenzymes.
- They helped the body function properly and perform chemical reactions.
