									The Cell Theory

Slide 1:
Before microscopes were invented, people believed that diseases were caused by _____ and
____________ _____________. As scientists began using microscopes, they quickly realized they were
entering a new world–one of ____________. ____________ enabled scientists to _________ and study -
_______, the basic units of living organisms.

Slide 2:
__________ ________ was an English scientist who lived at the same time as van ___________ (the
first person to use a microscope). Hooke used a ________ ___________ microscope to study cork, the
dead part of oak tree bark. Hooke named the compartments he saw in the cork ________. He and
some other scientists concluded that
___________________________________________________________________________________.

Slide 3:
Three parts of the Cell Theory are:
1)

2)

3)

Slide 4:
Cells that do not contain internal membrane-bound structures are called ___________ cells. The cells
of most unicellular organisms such as ___________ do not have __________ ____________ structures
and are therefore called prokaryotes.

Slide 5:
Cells containing _________ ___________ structures are called ___________ cells. Most of the
multi-cellular plants and animals we know are made up of cells containing membrane-bound structures
and are therefore called _____________.

Slide 6:
The membrane-bound structures within eukaryotic cells are called ____________. Each organelle has a
specific function that contributes to cell ____________.

Slide 7:
All living cells must maintain a ___________ regardless of internal and external conditions. This balance
is ______________. Survival depends on the cell’s ability to maintain the proper conditions within itself.

Slide 8:
The ______________is the boundary between the cell and its environment.



Slide 9:
The Plasma Membrane allows a steady supply of _________, amino acids, and _________ to come into
the cell no matter what the external conditions are. It also ___________ excess amounts of these
nutrients when levels get so high that they are harmful. Lastly, the plasma membrane allows _________
and other products to __________ the cell.
Slide 10:
By controlling what goes in and out of the cell, the plasma membrane maintains ____________. The
plasma membrane is able to maintain homeostasis because it is ____________ ____________ , it only
allows specific molecules in and out.

Slide 12:
The plasma membrane is composed of two layers of phospholipids back-to-back (or lipid-to-lipid).
____________ are lipids with a phosphate attached to them.

Slide 13:
The ____________ ____________ model describes the plasma membrane as a flexible boundary of a
cell. The phospholipids move within the membrane.

Slide 14:
____________ ____________allow needed substances or waste materials to move through the plasma
membrane.

Slide 15:
The ____________ ____________is a fairly rigid structure located outside the plasma membrane that
provides additional ____________and ____________.

Slide 16: The __________; AKA “The Boss”

                Label the parts.

Slide 17:
The ____________ ____________is an organelle that is suspended in the cytoplasm and is the site of
cellular ____________reactions. ER + Ribosomes = ____________ ____________

Slide 18:
The ____________ packages cellular products into a ____________and sends them out of the cell.

Slide 19:
____________are membrane-bound spaces used for temporary ____________of materials.

What is the difference between the vacuole in a plant cell compared to an animal cell?



Slide 20:
____________are organelles that contain ____________enzymes. They ____________excess or worn
out organelles, food particles, and engulfed viruses or bacteria. ____________=to break apart.

Slide 21:
____________are cell organelles that capture light energy and produce ____________to store for a later
time. The chloroplasts belongs to a group of plant organelles called ____________, which are used for
storage.

Chloroplasts contain a green pigment called ____________. Chlorophyll traps light energy and gives
leaves and stems their green color.
Slide 22:
____________are membrane-bound organelles in plant and animal cells that ____________energy for
the cell. A mitochondria has a highly ____________inner membrane. Energy storing molecules (ATP)
are produced on inner folds

Slide 23:
Cells have a support structure called the ____________within the cytoplasm. The cytoskeleton is
composed of ____________and microfilaments. Microtubules are thin, hollow cylinders made of protein
and ____________are thin solid protein fibers.

Slide 24:
Some cell surfaces have cilia and flagella, which are structures that aid in ____________or feeding. Cilia
and flagella can be distinguished by their structure and by the nature of their action.

Slide 25:
____________are short, numerous, hair-like projections that move in a wavelike motion.
____________are long projections that move in a whip-like motion. Flagella and cilia are the major
means of locomotion in ____________organisms.
