chloroplasts
|
these organelles capture energy from sunlight and use it to produce food for the cell.
|
|
nucleic Acids
|
Nucleic acids are very large organic molecules made up of C, O, H, N, and P. Nucleic Acids contain all the instuctions to carry out all the fuctions of life
|
|
cell wall
|
a stiff wall surrounds the cell membrane giving the cell and rigid boxlike shape.
|
|
Enzyme
|
An Enzyme is a type of protein that speeds up a chemical reaction in a living thing.
|
|
What are the building blocks of proteins?
|
Amino Acids
|
|
Substances that can move into and out of a cell do so by one of these three methods. What are they?
|
diffusion, osmosis, active tansport
|
|
Ribonucleic acids
|
plays an important role in the production of proteins.
|
|
Deoxyribonucleic Acids
|
the genentic material that carries information about an organism that is passed form parent to offspring.
|
|
Compound microscope
|
A light microscope that has more than one lens
|
|
selectivly premable
|
which means that some substances ca pass through wile others cannot.
|
|
Microscope
|
an instrument that makes small objects look larger
|
|
What did Robert Hooke do?
|
He invented the firse compound microscope
|
|
Diffusion
|
is the process by which molecules tend to moce from an area of hogher concentraction to an area of lower concentraction.
|
|
active tansport
|
thw movement of material through a cell membrane using energy.
|
|
Scanning Tunneling Microscope (STM)
|
A Stm measures electrons that leak or "tunnel" from the surface of a specimen.
|
|
Endoplasmic Reticulum
|
Theis metwoek of passafe ways carries materials from one part of the cell to another.
|
|
passive transport
|
the movement of materials through a cell membranr without using energy
|
|
What is the main difference between active transport and passive transport?
|
Active transport requires the cell to use energy while passive transport does not.
|
|
Transmission Electron Microscope (TEM)
|
TEMs make images be sending electrons through a very thinly sliced specimen
|
|
chromatin
|
thin strands floating in the nucleus, contain the genetic material, the insturctions that direct the function of a cell.
|
|
What is the cell theroy?
|
The cell theroy is
All living things are composed of cells. Cells are the basic unit of structure and function in living things. All cells are produced from other cells. |
|
compound
|
where two or more element are chemically combined
|
|
ribosomes
|
These small structures function as factories to produce proteins. Ribosomes may be attached to the outer surfaces of the endoplasmic reticulum, or they may float free in the cytoplasm.
|
|
Some cells that are carried into and out of the cells are calicum, potassium, and sodium
|
|
|
Lysosomes
|
These small organelles found in many animal cells contain chemicals that break down food particles and worn out cell parts.
|
|
Scanning Electron Microscope (SEM)
|
This Microscope sends a beam of electrons over the surface of a specimen rather than through it.
|
|
inorganic compounds
|
compounds that do not contain carbon
|
|
Engulfing
|
first the cell surrounds or First the cell membrane engulfs a particle. Once the particle is engulfed the cell membrane pinches off and forms a vacuole within the cell.
|
|
molecule
|
the smallest unit in a compound
|
|
Nucleus
|
Directs all of the cells activities including reproduction.
|
|
magnification
|
the ability to make things look larger that they are.
|
|
The four most important organic compounds
|
lipids, proteins, arbohydrates, nucleic acids.
|
|
golgi body
|
The golgi bosies receive materials through the and send them to other parts of the cell.
|
|
Mitochondria
|
Most of the cell's energy is produced within these rod-shaped organelles.
|
|
organic compounds
|
compounds that contain carbon
|
|
Cells
|
the basic units of structure and function in living things
|
|
vacuole (in plants)
|
Most mature plant cells have a vacuole. The sac within the cytoplasm stores water, food, waste, and other materials.
|
|
Nucleolus
|
where ribosomes are produced
|
|
How do the lens or lenses in a light microscope magnify and object?
|
By bending the light that passes through them
|
|
carbohydrates
|
are energy rich organic compounds made up of the elements C, H, O. Sugars and starches ate examples of carbohyrates.
|
|

|
A lens where the middle is thicker then that around the rim
|
|
resoultuion
|
The ability to clearly distinguish the individual part of an object. Resoultion is another term for th sharpness of an image.
|
|

|
|
cell membrane (in plants)
|
The cell membrane protects ythe cell and regulates what substances enter and leave the cell.
