THE
ORGANELLE
ORGAN
SHOW
You will recall that
cells are the third
tier in the level of
complexity; between
molecules and ????????
tissues
Within most cells these
are membrane bound, that
is they have a membrane
surrounding them and
composed of membranes.
organelles
An envelope is a
double membrane which
has pores for flow of
material.
Nuclear
Envelope
A dark area of
chromatin, it is
involved in making
ribosomes.
Nucleolus
Outside the nucleus,
inside the cell
membrane, the liquid
portion (rich in
proteins) that allows
dissolved molecules to
move within the cell.
Cytosol
Cytosol and organelles
combined are called
the ????
Cytoplasm
A spherical structure
found either free
floating in cytosol or
attached to ER. These
structures are the
site of protein
synthesis.
Ribosomes
A membrane system that
may be continuous with
the plasma membrane.
Endoplasmic
Reticulum
Has many ribosomes on
it and is the site of
protein production
(for secretion outside
the cell).
RER
This has no ribosomes
and serves to package
the proteins produced
in the RER. Proteins
are collected within a
bubble formed by the
membrane
SER
This is a membrane
system located close
to the plasma membrane
where proteins are
modified and leave
within a vesicle
formed by membranes.
Golgi
Apparatus
The main site of energy
release inside the cell.
Many enzymes are located
within to help release
energy from food molecules.
The folded inner membranes
assist in ATP production.
Mitochondria
These structures are
found in cells which
produce their own food
(plants and
autotrophs).
Plastids
Some examples of plastids
are:
chloroplasts - chlorophyll.
chromoplasts - flowers and
fruits.
leucoplasts - starch formed
from sugars here.
What colour are they?
green; red,
yellow and
orange, clear
Cell’s storage
containers. These are
often large in plant
cells and contain
mostly water. They may
also contain food,
pigments and salt.
Vacuoles
These are structures
that contain enzymes
used to digest old
cell structures. In
animal cells these may
aid in digesting food
particles in a food
vacuole.
Lysosomes
A system of microtubules
and proteins that acts
like a scaffolding
structure within the
cell. It can give a cell
shape and allow for the
passage of organelles.
Cytoskeleton
Common to animal cells,
these structures are
used during cellular
reproduction, pulling
the chromosomes to
daughter cells during
Anaphase and Telophase.
Centrioles
A barrier around the
cell that allows only
certain molecules in
or out of the cell. It
is composed of
phospholipids with
protein molecules
embedded within.
plasma
membrane
By definition, an organ system is an
organ or group of organs that are
comprised of specific tissue types. These
tissues are usually coordinated so that
they can perform specific functions for
the whole animal. Specific tissue types
can be created by cells that produce the
same proteins and perform the same
functions. (muscle cells have special
proteins and nerve cells have special
lipids, both cell types have specific and
different functions)
Our bodies are
composed of four
general types of
tissues, they are:
Epithelial tissues,
Connective tissues,
Nerve tissue and
Muscle tissue.
There are three general
types of this tissue and
they may be found in the
gut, circulatory system
and attached to the
skeletal system.
Muscle tissues (smooth,
cardiac and skeletal
muscle).
These tissues are
those that cover the
surfaces and linings
of organ systems (like
the skin surface,
stratified squamous
epithelium).
Epithelial
tissues
Can give structure to the
body by serving to attach
or support tissues (may be
referred to as support
tissues in some texts).
These include bone and
cartilage and loose tissue
such as blood cells, fat
cells, and loose fiberous
tissue.
Connective
tissue
Found through out the
body and allow for
communication between
tissues of the body
