CellBasic unit of a living
organism that can perform processes of life
6th grade Chapter 1 Vocabulary
The basic unit of structure and
function for all living things is the cell.
6th grade Chapter 1 Vocabulary
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
6th grade Chapter 1 Vocabulary
A set of statements called the cell
theory describe the basic concepts
about cells.
6th grade Chapter 1 Vocabulary
Cell MembraneThin structure, mostly lipids
and protein, encloses the cytoplasm and nucleus in
both plant and animal cells
6th grade Chapter 1 Vocabulary
The thin outer covering, or the cell membrane, controls what enters and exits
cells.
6th grade Chapter 1 Vocabulary
CytoplasmA jelly like substance that makes up all living material in a cell except the nucleus
6th grade Chapter 1 Vocabulary
The living material in the cell,
excluding the nucleus, is called the cytoplasm.
6th grade Chapter 1 Vocabulary
Cell activities, including division, are controlled by information in the
cell’s nucleus.
6th grade Chapter 1 Vocabulary
MitochondriaRod-shaped cell structures that convert energy in food
molecules to energy the cell can use to carry out its
function
6th grade Chapter 1 Vocabulary
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
6th grade Chapter 1 Vocabulary
Endoplasmic Reticulum
The endoplasmic reticulum carries proteins and other materials from
one part of the cell to another.

OsmosisBecause cells cannot
function properly without adequate water, many
cellular processes depend on osmosis.

A property of cell membranes that allows
some substances to pass through, while others
cannot
