The document lists and describes 9 major cell organelles: 1. The nucleus, which contains DNA and RNA and controls the cell. 2. The endoplasmic reticulum, which has two kinds - rough and smooth - and is involved in protein transport and lipid/toxin processing. 3. Ribosomes, which are dot-like structures that synthesize proteins and are either free-floating or attached to the ER. 4. The Golgi apparatus, which packages materials for export from the cell and modifies lipids and proteins. 5. Mitochondria, which are the primary energy producers and have their own DNA. 6. Chloroplasts in plant cells, which perform photosynthesis using

3. There are 9 major cell organelles :-

4.  Control Center of the cell
 Contains DNA and RNA
 Large, roundish organelle
 Can produce Proteins

5.  Folded membrane that
extends through the
cytoplasm to the nuclear
membrane
 2 Kinds:
 Rough- Has ribosomes attached
and is involved with protein
transport
 Smooth- Lacks ribosomes and is
involved with detoxification of
poison and lipid synthesis

6.  Dot-like structures produced in the nucleus
 Site of protein synthesis
 Each ribosome is composed of 2 sub-units: small
and large
 2 type of ribosomes:
 Free: floating in the cytoplasm
 Attached: associated with the ER

7.  Stacks of sacs with
vesicles pinching off from
the edges
 Packages materials for
export from the cell
 Will modify lipids and
proteins
 Stores and packages
materials for export out
of cell

8.  Primary energy
producers of cells
 Double membrane
 Produces ATP via
aerobic respiration
 Have their own DNA and
method of replication
 Endosymbiotic Theory

9.  Site of photosynthesis.
 Chlorophyll provides Green Color to plants.
 “ Endosymbiotic Theory ”

10.  Single membranes that
surround solid or liquid
contents
 Vacuole will as a
container for the cell
 Plant cells usually have
1 large vesicle filled
with water
 50-90% of a plant cell’s
volume is a vacuole

11.  Thin layer of cellulose
that surrounds the cell
 Permeable to many
substances
 Provides strength and
support to the plant

12.  Semi-permeable
membrane that lets some
things in and prevents
materials from leaving
 Provides limited structure
 Lipid bilayer
