CELLS
The basic unit of structure and
function in living things.
All living things are composed of cells.
CELL THEORY
Cells are the basic units of structure and
function in living things.
All cells are produced from other cells.
CELL MEMBRANE
A cell structure that controls which
substances can enter and leave the
cell.
CELL WALL
A rigid layer of nonliving material that
surrounds the cells of plants and some
other organisms.
An organelle that helps to protect and
support the cell. (not in animal cells)
NUCLEUS
A cell structure that contains nucleic
acids, the chemical instructions that
direct all the cell’s functions
RIBOSOMES
A small grain-like structure in the
cytoplasm of a cell where proteins are
made.
LYSOSOMES
A small-round cell structure containing
chemicals that break down large food
particles into smaller ones.
VACUOLES
A sac inside a cell that acts as a
storage area.
TISSUES
A group of similar cells that work
together to perform a specific
function.
ORGANS
A group of different tissues that
function together.
CHLOROPLASTS
A structure in the cells of plants and
some other organisms that captures
energy from sunlight and uses it to
produce food.
MITOCHONDRIA
Rod-shaped cell structures that
convert energy in food molecules to
energy the cell can use to carry out its
functions.
Releases energy from the nutrients.
ORGAN SYSTEMS
A group of organs that work together
to perform a major function.
CYTOPLASM
Jelly-like substance within a cell that
holds most of the organelles
TRAIT
A characteristic that an organism can
pass on to its offspring through its
genes.
REPRODUCTION
The transmitting of genetic
information from one generation to
the next.
ORGANELLES
The tiny cell structures that carry out
the functions of the cell.
GOLGI
A structure in a cell that receives proteins
and other newly formed materials from the
ER(endoplasmic reticulum), packages them,
and distributes them to other parts of the
cell.
ER
Endoplasmic Reticulum
A cell structure that forms a maze of
passageways in which proteins and other
materials are carried from one part of the
cell to another.
