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

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
“Im tough. Beware”

Organelle Function
Plant or Animal?
Cell Membrane Controls movements of 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
Air traffic controllerDNA

Plant or Animal?
Cell Membrane Controls movements of materials in and out of the cell
Animal
Nucleus Controls the activities of the cell
Animal
DNA The genetic 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.

All plants and
animals are
composed of
cells and cell
products
(organelles)

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
Plant Cell
Animal Cell
