Download PowerPoint on the parts of a cell

Cell Parts and Functions
Cell Wall
 Only
in plant cells
 Helps
to support and protect the cell
Cell Membrane
 All
cells have a cell membrane
 Controls
which substances go into and out
of a cell which include food, water and
oxygen
Nucleus
 The
control center of a cell directing all of
the cells activities
 Also
houses the DNA or genetic material of
the cell
Nuclear Envelope
 The
membrane the surrounds the nucleus
 Allows
material to pass into or out of the
nucleus while keeping bad stuff out
Chromatin
 Tiny
thread like material in the nucleus
that contain the genetic material and
direct the cells functions.
Nucleolus
A
dense ball inside the nucleus where
ribosomes are made
Cytoplasm
 Region
between the cell membrane and the
nucleus that is a thick gel like substance
 Contains
 The
most of the cells organelles
liquid part of the cell
Mitochondria
 Known
as the powerhouse of the cell
because they convert energy in food
molecules into energy the cell can use and
carry out it’s functions.
Endoplasmic Reticulum (ER)
 Passageways
that carry proteins and other
molecules from one part of a cell to
another
Ribosomes
 Attach
to the surface of the ER and
function as factories to produce proteins
Golgi Bodies
 Receive
proteins and other newly formed
materials from the ER, package them, and
distribute them to other parts of the cell
Chrloroplasts
 ONLY
in plant cells
 Capture
energy from sunlight and use it to
produce food for the cells
 Contain
chlorophyll which is a green
pigment that gives plants their green color
Vacuoles

Storage area of the cell

Most plants have one large vacuole

Some animal cells do not have vacuoles.

Can store food and waste products
Lysosomes
 Small
round structures that contain
chemicals that break down certain
materials in a cell
 To
lyse means to split
Know this!!!
 There
are levels of organization involving
cells
 In
many-celled organisms cells are often
organized into
Tissues
Organs
Organ
systems
