inorganic compounds
compounds that don't contain the element carbon
bacterial cell
does not have a cell wall, cell membrane, and nucleus.
proteins
large organic molecules made of carbon, hydrogen, oxygen, nitrogen, and sometimes sulpher
Cells
The basic structure and function in living things.
nucleic acids
very large organic molecules made of carbon, oxygen, hydrogen, nitrogen, and photosphorus. contain the instructions that cells need to carry out all the functions of life.
cell theory #3
all cells are produced from other cells
DNA
deoxyribonucleic acid- genetic material that carried information about an organism that is passed from parent to offspring.
Who was one of the first people to observe cells?
Robert Hooke
lipids
fat, oils, and waxes
energy rich organic molecules made up of carbon, hydrogen, and oxygen.
ribosomes
produce proteins the ribosomes realease some proteins throught the wall of the ER.
compound
when two or more elements combine chemically
Microscope
and instrument that makes small objects look larger
Whithout enzymes, what would happen?
many chemical reactions that are necessart for life would either take too long, or not occure at all.
lysosomes
small round structures that contain chemicals that break down large food particles into smaller ones.
element
any substance that cannot be broken down into simpler sucstances.
What made it possible for people to discover and learn about cells?
the invention of the microscope.
atom
the smalles unit of an element
golgi bodies
the cell's mailroom. reciever proteins and other newly formed amterials form the endoplasmic reticulum, package them, and distribute them throughout the cell.
RNA
ribnucleic acid- important role in the production of proteins. found in the cytoplasm, as well as the nucleus.
compound microscope
a light microscope that has more than one lens
The most important groups of organic compounds found in living things are...
cargohydrates, lipids, proteins, and nucleic acids.
chromatin
contain the genetic material, the instructions that direct the funcitions of a cell
enzyme
type of protein that speeds up a chemical reaction in a living thing.
cell theory #2
cells are the basic structure and function of living things.
molecule
the smallest unit of most compounds
what is the cell wall made of?
a tough, yet flexible material called cellulose
organic compounds
contain carbon
Cell Theory #1
all living things are composed of cells
amino acids
protein molecules that are made up of smaller molecules called <------
cell membrane
(all cells) the cell membrane is locatated just inside the cell wall.
Without water, what would happen?
most chemical reactions within cell could not take place.
what do the organelles do in the cytoplasm?
produce energy, build and transport needed materials, and store and recycle wastes.
_______microscopes use a beam of what to instead of light to examine a specimen?
elecron Microscopes
The cell membrabe controls what?
what substances come into and out of a cell
cell wall
(plant cell) a rigid layer of ninliving naterial that surrounds the cells of plants and some other organisms.
mitochondria
produces most of the energy the cell needs to carry out its funtions.
cytoplasm
the region between the cell membrane and the nucleus. a clear, gel-like material. the fluid is constantly moving
msgnification
the ability to make things larger than they really are
How does lens or lenses in a light microscope magnify an object?
by bendidng the light
convex lens
a lense with a curved shape
resolution
the ability to clearly distinguish the individual parts of an objects
organelles
carry out specific functions within a cell
endoplasmic reticulum
a maze of passageways that carry proteinds and other materials form one part of the cell to another.
ribosomes
the organellswhere proteins are produced

nucleolus
where ribosomes are made
chloroplasts
capture energy from sunlight and use them to produce food for the cell. they give a plant its green color.
vacuole
the storage area of the cell.
