• You will recall that cells are the third tier in
  the level of complexity between molecules and
  ????????
• tissues

3
Within most cells these are membrane bound, that
is they have a membrane surrounding them and
composed of membranes.
4
organelles
5
An envelope is a double membrane which has pores
for flow of material.
6
Nuclear Envelope
7
A dark area of chromatin, it is involved in
making ribosomes.
8
Nucleolus
9
Outside the nucleus, inside the cell membrane,
the liquid portion (rich in proteins) that allows
dissolved molecules to move within the cell.
10
Cytosol
11
Cytosol and organelles combined are called the
????
12
Cytoplasm
13
A spherical structure found either free floating
in cytosol or attached to ER. These structures
are the site of protein synthesis.
14
Ribosomes
15
A membrane system that may be continuous with the
plasma membrane.
16
Endoplasmic Reticulum
17
Has many ribosomes on it and is the site of
protein production (for secretion outside the
cell).
18
RER
19
This has no ribosomes and serves to package the
proteins produced in the RER. Proteins are
collected within a bubble formed by the membrane
20
SER
21
This is a membrane system located close to the
plasma membrane where proteins are modified and
leave within a vesicle formed by membranes.
22
Golgi Apparatus
23
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.
24
Mitochondria
25
These structures are found in cells which produce
their own food (plants and autotrophs).
26
Plastids
27
Some examples of plastids are chloroplasts -
chlorophyll.chromoplasts - flowers and
fruits.leucoplasts - starch formed from sugars
here. What colour are they?
28
green red, yellow and orange, clear
29
Cells storage containers. These are often large
in plant cells and contain mostly water. They may
also contain food, pigments and salt.
30
Vacuoles
31
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.
32
Lysosomes
33
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.
34
Cytoskeleton
35
Common to animal cells, these structures are
used during cellular reproduction, pulling the
chromosomes to daughter cells during Anaphase and
Telophase.
36
Centrioles
37
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.
38
plasma membrane
39
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)
40
Our bodies are composed of four general types of
tissues, they are Epithelial tissues,
Connective tissues, Nerve tissue and Muscle
tissue.
41
There are three general types of this tissue and
they may be found in the gut, circulatory system
and attached to the skeletal system.
42
Muscle tissues (smooth, cardiac and skeletal
muscle).
43
These tissues are those that cover the surfaces
and linings of organ systems (like the skin
surface, stratified squamous epithelium).
44
Epithelial tissues
45
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.
46
Connective tissue
47
Found through out the body and allow for
communication between tissues of the body
48
Nerve tissues
