Living Things
Plant and Animal Cells
Cell Theory (Part 1)
 Many people of ancient societies believed that
volcanoes, oceans, mountains and fire were “alive” in
the same way that animals, plants and other organisms
are alive.
 However, science has changed the way people
understand the world
 Most people now recognize the difference between
living organisms and non living things
{Gateways to Science: Region 4 p165}
Characteristics
Slow –Moving Turtle
Fast-Moving River
Uses energy?
Moves?
Responds to
environment?
Grows?
Reproduces?
Develops over time?
Has a life span?
Is made of cells?
{Gateways to Science: Region 4 p165}
 1) How is a fast moving river similar to a living
organism?
 2) How is a fast-moving river different from a living
organism?
{Gateways to Science: Region 4 p165}
 We just talked about how growing is a characteristic of
a living organism
 Scientists have data that
shows that Mount
Everest, the tallest
mountain on Earth is
growing taller each year.
 Is Mount Everest a living
organism?
 Why or Why not?
 Invented powerful
microscopes and started
looking at all he could
see and found ….
Then Robert Hooke called
those little tiny things
CELLS
Because they reminded him
of tiny rooms where
monkeys are kept
 Similar to how bricks are
the building blocks of a
building
Penguin Blood Cells
Plant Cells
Cheek
Nerve
Blood
Skin
Muscle
Hair
These two gentleman
looked at many, many
cells and over coffee
struck up
conversation about
their cell observations
They then came up
with the
CELL THEORY
Matthias Schleiden
Theodor Schwann
 They noticed that inside the cells of plants and
animals seemed to be even smaller particles
They noticed that each of these smaller particles have
jobs inside the cell that made it function
Just like humans have
ORGANS that keep us
alive and have certain
functions ..
cells have
ORGANELLES
The CELL MEMBRANE surrounds the animal cell and
controls movement of materials into and out of the
cell

Cell Membrane

materials in and
out of the cell
Animal
 The NUCLEUS is a very important organelle in the cell.
It controls all activities of the cell and contains DNA

Animal
Nucleus
Controls the

activities of the cell
DNA

material in the cell
Animal
 Plant cells have similar organelles to an animal cell but
there are two additional organelles that are ONLY
FOUND IN PLANT CELLS
 The CELL WALL provides support for the plant cell. It
protects the cell like our police department protect us.
This is only found in a plant cell.

 The CHLOROPLASTS produce food for the plant cell
by a process called photosynthesis.

 Use construction paper
to create the cell
assigned to you
 Only include and label
the organelles we talked
about in class
 Write a brief description
below each labeled
organelle

