This document describes the structure and functions of various organelles found within cells. It explains that the cell membrane controls movement in and out of the cell, and that the cell wall supports and protects plant cells. The nucleus contains genetic material and is surrounded by the nuclear membrane. The endoplasmic reticulum helps transport proteins, with the smooth ER involved in fat synthesis and the rough ER containing ribosomes. Mitochondria produce energy and the Golgi apparatus packages proteins for transport. Lysosomes digest materials and vacuoles store reserves and control water levels. Chloroplasts are found in plant cells and are the site of photosynthesis.

6. Organelles

7.  Outer membrane of cell that controls movement
in and out of the cell
 Double layer

8.  Most commonly found
in plant cells &
bacteria
 Supports &
protects plant cells

9.  To control cell
activities
 Separated from
cytoplasm by
nuclear
membrane
 Contains genetic
material - DNA

10.  Surrounds nucleus
 Made of two layers
 Openings allow
material to enter
and leave
nucleus

11.  Inside nucleus
 Contains RNA to build proteins

12.  Gel-like mixture
 Surrounded by cell
membrane
 Contains
material for
cell metabolism

13.  Moves materials around in cell
 Smooth ER: lacks ribosomes => the place of fats
synthesis
 Rough ER : ribosomes embedded in surface => to transport
protein package to other organelles

14.  Each cell contains
thousands
 The place of
protein
synthesis
 Found on
ribosomes &
floating throughout
the cell

15.  Produces energy
through chemical
reactions – breaking
down fats &
carbohydrates
 Controls level of water
and other materials in
cell

16.  Protein
'packaging'
 Move
materials
within and out
of the cell

17.  Digestive organelle for proteins, fats, and
carbohydrates
 Transports undigested material to cell membrane for removal
 Cell breaks down if lysosome explodes

18.  Membrane-bound sacs
for storage, digestion,
and waste removal
 Contains water solution
 Help plants maintain
shape
 a place to store
food reserves

19.  Play a role in cell reproduction

20.  Usually found in plant cells
 Contains green chlorophyll
 Where photosynthesis takes place
