scientific classification and cells powerpoint

1. Every living thing on this earth is
made out of the same thing!
Believe that?

2. If you were going to divide everything on earth
into just two groups,
what would the groups be?

3. What is the difference between a rock
and a tortoise?

4. Organisms react to their environment
• The rain falls on both the rock
and the tortoise.
• Only the tortoise, though, can
get thirsty and drink the water.

5. Most Organisms Can Move
•A tortoise can
move into
sunlight to get
warm.
•A rock can’t

6. ORGANISMS
THINGS THAT ARE
ALIVE (OR WERE ONCE
ALIVE) ARE CALLED
ORGANISMS

7. What
category
would you
put these
stuffed deer
heads in?

8. Are these
organisms?

9. All living
things
(organisms)
are made out
of the same
building
blocks

11. NO, not LEGOS
But close….

12. CELLS ARE THE BUILDING BLOCK OF ALL
ORGANISMS
Organisms are all just a
collection of cells, but, like
LEGOS, cells can be combined in
many different ways to make
different organisms .

13. All organisms are made of cells.

14. The simplest
organisms
have just
one cell

15. Say hello
to
ALGAE,
an
organism
with just
one cell

16. You are made up of many millions of cells.

17. A complicated
organism like a
human being
has many
different kinds
of cells.

25. HOW WOULD YOU DIVIDE
ALL ORGANISMS
INTO 2 GROUPS?

26. Plants and Animals

27. WHAT MAKES PLANTS DIFFERENT
FROM ANIMALS?
Plants make their own food.
They don’t need to eat.
They can make energy from sunlight
and water, using carbon dioxide,
which is what we breathe OUT

28. Sunlight
Without
sunlight,
there
wouldn’t
be any life
on earth at
all!

29. Plants
•Without plants,
animals would not
be able to get
energy.
•Without energy,
animals would not
be able to live.
•Without plants,
there wouldn’t be
any animals at all!

30. Think about what it
would be like to be
a plant.
You would never
have to go to the
grocery store.

31. How would your family’s life be
different if your family didn’t
have to spend time looking for
food or making money to buy
food?

33. Plant cells and animal cells are a
little different

34. Plant cells have chloroplasts and cell
walls. Animal cells don’t.

38. Both animal
and plant cells
have:
1.Nucleus
2.Cytoplasm
3.Vacuole
4.Cell
membrane
5.Mitochondria

39. Every cell has a cell membrane.
It keeps good things in and bad things out of the cell.
This is a picture of a real cell membrane.

40. Cytoplasm
Cytoplasm
is a jelly
that holds
everything
inside the
cell in
place, like
packing
material.

41. What does this have to do with Cytoplasm?

42. NUCLEUS
•The nucleus is
the brain of the
cell.
•Almost all cells
have a nucleus.

43. Nucleus
In this cell model, the orange is the nucleus.

44. Can you
find the
nucleus
in this
cell
model?

45. Mighty Mitochondria
•All cells have
mitochondria.
•This is the
power plant of
the cell.
•Think “Mighty
Mitochondria”

46. Mighty Mitochondria

47. Mighty Mitochondria
In this photograph of a real cell, the nucleus is blue and the
mitochondria are red.

49. This is a real
Mitochondrion.

50. In this cell model, the blue cookies with the frosting are the mitochondria.

51. Mighty Mitochondria
In this cell model, the orange pellets are the mitochondria.

52. Mighty Mitochondria
In this
model, the
pink and
green
candies are
the
mitochondria

53. Vacuole
•In an animal cell,
the vacuole fills
with food being
digested and waste
material that is on
its way out of the
cell.
•Think of the
vacuole as a
vacuum cleaner for
the animal cell.

54. VACUOLE IN ANIMAL CELL
The
white
cotton
ball is the
vacuole
in this
animal
cell
model.

55. Can you see the vacuole in this one-celled animal?

56. PLANT CELL VACUOLE
The big brown
bean-shaped
structure
is this plant cell’s
vacuole.

57. VACUOLES
When a
plant is
well-
watered,
water
collects in
cell
vacuoles
producing
rigidity in
the plant.

58. When a plant
doesn’t have
enough water
to fill up its
vacuoles, the
plant wilts.

59. VACUOLES
In this
model,
the big
blue
blobs are
the
vacuoles

60. Remember the
two things plant
cells have that
animal cells don’t
have:
chloroplasts
and
cell walls .

61. CHLOROPLASTS
Plant cells have something
animal cells don’t:
CHLOROPLASTS
These are the
kitchens of the
cell.

62. •This is a
picture of a
real cell.
•The things
that look
like pickles
are
chloroplasts

64. Plant cells have :
1.Chloroplasts that
make their food.
2. Thick Cell Walls
Animal Cells don’t have these. Poor
animal cells!

65. Isn’t this a beautiful cell wall?

66. Plant Cell
In this model, the sides of the box are the cell walls

67. Animal cells don’t have cell walls.
Plant cells do!

68. What are the two
things plant cells
have that animal
cells don’t have?
