Compound Light Microscope (CLM)
A microscope that uses a series of lenses to see light passed through a sample
A special organelle that contains the cell's DNA, and stores information the cell needs to perform protein synthesis
A special boundary that surrounds the cell and controls what gets into & out of the cell
The ability to allow some substance to pass through, while keeping others out
two layers of phospholipids are arranged tail-to-tail with the heads on the outside/ the head is hydrophilic and the tail is hydrophobic
proteins that create tunnels through which are polar or big to get the bilayer can enter and leave the cell
the movement of substances from an area where there is high concentration of the substance to an area where there is a lower concentration of the substance
the point at which there is an equal concentration of a substance, or on both sides of the membrane
movement of substances through the plasma membrane without the use of energy energy by the cell
following the natural "flow" or tendency for things to want to move from areas where they are highly concentrated , to areas where they are less concentrated
typr of passive transport in which substances pass through the plasma membrane on their own
type of passive transport in which substances use a transport protein to get through the plasma membrane
proteins embedded in the plasma membrane which create tunnels for certain substances to pass through the plasma membrane
movement of substances through the plasma membrane with the use of energy by the cell
(Adenosine DiPhosphate) when a bond is broken between the phosphate groups, energy is released and this is the reaction of ATP
process by which the cell brings a substance in by surrounding it in a segment of the plasma membrane
the process by which a cell releases a substance by enclosing it in a vesicle, and fusing the vesicle to the plasma membrane
a network of fibers which create support for the cell, and anchor organisms in place inside of the cell
a folded system of membranes where proteins, lipids and carbohydrates are made
a flattened sack of membranes that modifies, sorts and packages the proteins made in the rough ER
vesicles that contain digestive enzymes which break down food particles, waste, and worn-out organelles
organelles that make ATP energy for the cell by turning sugars into energy using the process of cellular respiration
organelles that capture light energy(from the sun) and convert it to food for the plant(glucose) through the process of photosynthesis
1. All living organisms are made of one or more cells
2. Cells are the basic units of structure & organization of organisms
3. All cells come from other cells
1. Include plant and animal cells 2. have organelles 3. have nucleus 4. have a plasma membrane
1. include unicellular organisms 2. do not have a nucleus or any other organelle 3. have a plasma membrane 4. has DNA that floats freely
Types of Passive Transport
Simple diffusion, facilitated diffusion(including transport proteins), and osmosis
concentration of water outside of the cell is Higher than the concentration of water inside of the cell
concentration of water outside the cell is LOWER than the concentration of water inside the cell
