a) Can be found “free” within the cell or bound to another organelle.
b) Produces usable energy for the cell through a process called cellular respiration. Also
known as the “power house” of the cell.
c) Controls cellular activities via genes.
d) Semi-permeable membrane enclosing the cell and composed of fluid-like phospholipid
bilayer
e) Known as the “synthesizer” it is involved in synthesizing proteins that will generally be
secreted outside the cell. Also involved in metabolic processes (ex. Detoxification)
f) Includes everything outside the nucleus and inside of the plasma membrane.
g) Packages molecules into vesicles for transport within or outside of cell.
Appears as flattened sacs (like stacked pitas).

energy.
i) Holds cellular waste products and material considered harmful for the cell. Can also store
important nutrients necessary for the cell and water.
j) These digest excess or worn-out organelles, food particles, and engulfed viruses or
bacteria.

Week 4: The Cell Follow Along
 A cell is the basic structural and functional unit of all living things.
Cell Theory states that:
 All living things are composed of organized cells that come from
________________, replicating cells.
 2. Cells are composed of smaller components called ______________.
 3. There are many different types of cells.
Eukaryotic Cell Organelles:
 Organelles are similar to mini-organs found in the cell.
 Like _________ function in our bodies, organelles perform specific jobs
within the cell.
 There are many different organelles, some of which are specific to either
plant or animal cells.
The Nucleus:
 “The DNA HOUSE”
 Contains DNA as chromosomes (or uncondensed as chromatin).
 Controls cellular activities via _______.
 Also found in the nucleus is the _____________, which is involved in
ribosome synthesis
 The nuclear envelope encloses the nucleus and is made of two membranes.
ENDOPLASMIC RETICULUM (ER):
“THE SYNTHESIZER”
Rough Endoplasmic Reticulum:
 RER synthesizes ___________ that will generally be secreted outside the
cell.
 Appears ____________ or “studded” due to embedded ribosomes.
Smooth Endoplasmic Reticulum:
 SER is responsible for __________________________.
 “Membrane Manufacturer”

RIBOSOMES
“THE PROTIEN FACTORIES”
 Ribosomes are involved in building _______________.
 Ribosomes can be found “free” within the cell or bound to another organelle.
THE GOLGI APPARATUS
“THE CELLULAR FEDEX DEPARTMENT”
 Packages molecules into _______________ for transport within or outside
of cell.
 Appears as flattened sacs (like stacked pitas).
LYSOSOME
“CLEANS UP LIKE LYSOL”
 Contain an array of enzymes capable of breaking down all types of
biological polymers such as proteins, nucleic acids, carbohydrates, and
lipids.
 _____________ excess or worn-out organelles, food particles, and engulfed
viruses or bacteria.
 They can be described as the stomach of the cell.
THE VACUOLE IN PLANTS
 Serves a similar function as the lysosomes found in animal cells.
 Holds _______________ products and material considered harmful for the
cell.
 Can also store important nutrients necessary for the cell and water.
MITOCHONDRIA
“THE POWER HOUSE”
 Produce usable energy for the cell through a process called
______________________.
 Found in Animal & Plant Cells
 “Energy Currency” = ATP
 Cellular Respiration is the set of metabolic reactions and processes that take
place in a cell that converts biochemical energy from obtained nutrients
into ____________________________.
CHLOROPLAST
“THE ENERGY CONVERTERS”
Name______________________________
Date_______________________________
 The site of ____________________ which is a process that converts solar
energy into chemical energy.
CYTOPLASM
“EVERYTHING IN THE MIDDLE”
 Cytoplasm = Cytosol + Organelles
 Cytosol : ___________________ surrounding the organelles.
 Includes everything outside the nucleus and inside of the plasma membrane.
PLASMA MEMBRANE
 Semi permeable membrane enclosing the cell.
 Composed of fluid-like phospholipid bilayer.
 Controls passage of substances in and out of the cell.
 Called the fluid mosaic model because some of the proteins float more or
less freely in the bilayer and they are presented in a mosaic fashion.
 Composed of hydrophilic heads and hydrophobic tails.
