VocabularyVocabularyCells Cells

Structure and Structure and FunctionFunction


CellBasic unit of a living

organism that can perform processes of life


Plant Cell

http://www.enchantedlearning.com/subjects/biology/cells/


Animal Cell


The basic unit of structure and

function for all living things is the cell.


Cell Theory1. All living things are made of

cells2. Cells are the basic units of

structure and function in living things

3. Cells come only from other living cells


Cell Theory

Robert Hooke

Anton van LeeuwenhoekTheodor Schwann

Rudolf Virchow


A set of statements called the cell

theory describe the basic concepts

about cells.


Cell MembraneThin structure, mostly lipids

and protein, encloses the cytoplasm and nucleus in

both plant and animal cells


Cell Membrane


The thin outer covering, or the cell membrane, controls what enters and exits

cells.


CytoplasmA jelly like substance that makes up all living material in a cell except the nucleus


Cytoplasm


The living material in the cell,

excluding the nucleus, is called the cytoplasm.


NucleusThe control center for most

cell’s activities


Nucleus

http://www.enchantedlearning.com/subjects/biology/cells/


Cell activities, including division, are controlled by information in the

cell’s nucleus.


ChloroplastAn organelle in a plant cell

that contains chlorophyll


ChloroplastChloroplast


The chlorophyll in a chloroplast gives a

plant its green color.


MitochondriaRod-shaped cell structures that convert energy in food

molecules to energy the cell can use to carry out its

function


Mitochondria


MitochondriaMitochondria are

the “power houses” of the cell.


Endoplasmic Reticulum

A cell structure that forms a maze of passage ways in which proteins and other materials are carried from

one part of the cell to another


Endoplasmic ReticulumEndoplasmic Reticulum


Endoplasmic Reticulum

The endoplasmic reticulum carries proteins and other materials from

one part of the cell to another.


Ribosome

A small grain-like structure in the

cytoplasm of a cell where proteins are

made


RibosomeRibosome


Ribosome

Ribosomes function as factories to

produce proteins.


Golgi bodyA structure in a cell that

receives proteins and other newly formed materials from the ER, packages them, and

distributes them to other parts of the cell


Golgi bodyGolgi body


Golgi bodyThe golgi body receives

proteins and other materials from the

endoplasmic reticulum.


VacuoleA sac inside a cell that acts as a storage area


Vacuole


VacuoleMost plant cells have one large

vacuole.


LysosomeA small, round cell structure containing chemicals that break

down large food particles into smaller ones


Lysosome


LysosomeLysosomes help break down old

cell parts.


Deoxyribonucleic acidThe genetic material that carries information about

an organism and is passed from parent to

offspring


Deoxyribonucleic acidDeoxyribonucleic acid


Deoxyribonucleic acid

DNA stands for deoxyribonucleic

acid.


DiffusionMovement of a substance

from an area of high concentration to an area of

low concentration

DiffusionThe smell of the orange diffused

through the room.


OsmosisDiffusion of water or other

solvent through a membrane


Osmosis


OsmosisBecause cells cannot

function properly without adequate water, many

cellular processes depend on osmosis.


Selectively permeable

A property of cell membranes that allows

some substances to pass through, while others

cannot


Selectively permeableSelectively permeable


Selectively permeable

A cell wall is like a gate. It can be selectively

permeable because it allows some items in but

doesn’t allow others.
