the egg cell and formed a
zygote. . .

21. What had to happen in order to change the four cells you saw
on the last slide to the small fetus you viewed on this slide?

22. What had to happen in order to change the four cells you saw
on the last slide to the small fetus you viewed on this slide?
The cells had to differentiate from stem cells, and they had to divide
so the animal could grow

23. Diversity within the
biosphere

Staph - a bacteria cell biosphere
It is the only cell
that is prokaryotic

36. Based on their structure, what is the function of these
nerve cells?

37. Based on their structure, what is the function of these
nerve cells?
Nerve cells have long projections that send and receive signals.

38. Just like different cells have different functions based
on their structure,
different parts of the cell (organelles) have specific
functions as well

39. The cell membrane

40. The cell membrane
Based on the video, what functions does
the cell membrane accomplish for the
cell?

41. The cell membrane
Based on the video, what functions does
the cell membrane accomplish for the
cell?
It provides structure, and it helps transport
molecules

42. The cytoplasm
*The cytoplasm is the liquid
and organelles inside the cell.
*Nutrients are dissolved in it.
*Materials the cells needs are
also dissolved in the liquid.

43. The nucleus
Function: It stores DNA (genetic
information) in the form of chromosomes

44. Mitochondria

45. Mitochondria
How does the structure of this organelle
relate to its function?

46. Mitochondria
How does the structure of this organelle
relate to its function?
It converts sugar into ATP through cellular respiration - the folds of the
inner membrane increase surface area.

47. The ribosome

48. The ribosome

49. The ribosome
Function:
Along with the
nucleus and the
endoplasmic
reticulum, the
ribosome helps
create new
molecules for
the cell
(proteins)

50. Lysosomes
Lysosomes are organelles that contain
enzymes that help the cell break down waste,
food, and dead cell parts

51. How is a plant cell different from
an animal cell?

52. Plant cells contain cell
walls for structure
They have a cell wall in addition to a cell membrane.
It is much more rigid, and it provides a framework for the
cell.

53. Plant cells contain cell
walls for structure
They have a cell wall in addition to a cell membrane.
It is much more rigid, and it provides a framework for the
cell.

54. Plant cells contain
chloroplasts

55. Plant cells contain
chloroplasts
Chloroplasts add in photosynthesis by absorbing sunlight

56. Plant cells contain
chloroplasts
Chloroplasts add in photosynthesis by absorbing sunlight

57. Plant cells contain
chloroplasts
Chloroplasts add in photosynthesis by absorbing sunlight
The large central
vacuole
has several
functions.
It can hold waste,
and it helps
maintains a cell’s
turgidity.
