CELLS
By Amy Lamarre- DWE
Objective
• Today I can compare
parts of plants & animals
that are needed for
growth & survival
Essential Questions
1. What are plant structures? How do they help
plants in growth and survival?
2. What are animal structures? How do they
help animals in growth and survival?
3. What are some of the similarities in plants
and animals? How are they different?
SET
• Picture in your mind an animal. Think
about all the internal body parts that
work together to help that animal
survive.
• On your whiteboard, make a list of all
the parts (large & small) that help this
animal survive.
Organisms
• Any living thing is called an organism.
• In plants and animals, we call the parts
of microscopic organisms structures.
• The different parts of each structure
each have a function or “a job”.
Cells
• Cells are the smallest living part in
animals and plants.
• Plant and animal cells are different,
although many of the structures are the
same.
• Living things such as humans, trees,
dogs and lions are ALL made up of
TRILLIONS of cells!
Animal Cells
• Mammals, including humans are made
up of various types of cells.
• Most animals & all humans have bone
cells, nerve cells, muscle cells and
blood cells, to name a few.
• Each type of cell has a different job to
keep the body functioning properly.
Structures in Animal
Cells
•
CELL MEMBRANE: Surrounds the inside of the cell. Controls
the movement of liquids. Water enters, wastes leave.
•
MITOCHONDRIA: “POWERHOUSE” of the cell. Gives the cell
energy!
•
•
NUCLEUS: Controls it all!
CYTOPLASM: Jelly-like liquid that fills the cell. Other structures
Plant Cells
• Plants are living organisms and have
cells similar to an animal cell.
• Instead of having cells like those that
support our blood & bones, plants have
cells that support its leaves and roots.
• A plant’s leaf cells make food for the
plant.
• A plant cell has all the parts of an
animal cell, but also has a Cell Wall &
Chloroplasts.
Unique structures in Plant
Cells
•
•
CELL WALL: A firm cell wall covers plants cells &
gives them a box-like shape.
CHLOROPLASTS: Make food for the plant. Green
from a substance called Chlorophyll; it takes in
energy from the sun. When combined with water &
CLOSURE
• Think in your mind, the two
structures that are unique to a
plant cell. Turn and tell your
shoulder partner those two parts.
• On the back of your notes, write a
20 cent summary (20 words) about
why cells are important for the
survival of mammals and plants.
