1. The Cell
Investigation 4

2. Targets Investigation 4
I can explain and identify that all living organisms are composed of cells which carry on the many functions needed to sustain life.
I can explain the differences and similarities between plant and animals cells as well as the organelle functions.

3. Characteristics of Life
Needs to Exchange gases
Needs to Remove waste
Needs water
Needs food (energy)
Responds to the environment
Grows
Reproduces
Moves
Made of a cell or cells with DNA

5. Unicellular & Multicellular Organisms

6. Unicellular Organism Lives on it’s own
Able to perform all the functions of life

7. Multicellular Organism
Exists as a group of cells
Performs all the activities of life when all the cells work together

8. Unicellular or Multicellular

15. Levels of Organization
Cell – Basic unit of life
Tissues – a group of cells that work together to perform a specific job
Organs – a group of tissues that work together to perform a specific job
Organ system – a group of organs that work together to perform a specific job
Organism – a group of organ systems that work together to perform a specific job.

18. Cell Games

19. Animal Cell Plasma Membrane What is the outer lining of a cell?
Plasma membrane (cell membrane)
What is the job of the plasma membrane?
controls what goes in and out of the cell

20. Animal Cell Ribosomes Where are ribosomes found?
on the endoplasmic reticulum and floating in the cytoplasm
What is created by the ribosomes when they follow instructions from the nucleus?
proteins

21. Animal Cell Mitochondria
What is produced in the mitochondrion that fuels the cells activity?
energy rich molecule – ATP
What is the energy rich molecules used for in the cell?
fuels most of the action in the cell

22. Animal Cell Nucleus What is the job of the nucleus?
directs the activity in the cell
What does the nucleus hold?
construction plans (DNA)
Where are genes found in a cell?
in the nucleus

23. Animal Cell Cytoplasm What fills the cell? a fluid called cytoplasm
What is suspended in the cytoplasm?
all of the organelles

24. Animal Cell
Cell Membrane
Nucleus
Cytoplasm
Mitochondria
Ribosomes

25. Plant Cell Cell Wall What are the two jobs of the rigid cell wall?
protects from injury
Maintains the shape of the plant cell
How does the cell wall maintain the shape of the cell?
fluid collects in the vacuole and presses against the cell wall

26. Plant Cell Plasma membrane
Where is the plasma membrane found in a plant cell?
it is the lining beneath the cell wall
What is the job of the plasma membrane?
controls what molecules pass in and out of the cell

27. Plant Cell Chloroplast
What is the main source of energy for a plant cell?
sunlight
Describe the process of photosynthesis
chloroplasts change the sun’s rays into energy that the cell can use

28. Plant Cell Large Central Vacuole What is stored in a vacuole?
water and nutrients
Waste materials so the cell does not become contaminated
What happens to the plant cell when the vacuole is low on water?
the plant droops (wilts)
How does the cell regain its shape?
when the vacuole is full of water

29. Plant Cell Ribosomes Where are ribosomes found?
on the endoplasmic reticulum and floating in the cytoplasm
What is created by the ribosomes when they follow instructions from the nucleus?
proteins

30. Plant Cell Mitochondria
What is produced in the mitochondrion that fuels the cells activity?
energy rich molecule – ATP
What are the energy rich molecules used for in the cell?
fuels most of the action in the cell

31. Plant Cell Nucleus What is the job of the nucleus?
directs the activity in the cell
What does the nucleus hold?
construction plans (DNA)
Where are genes found in a cell?
in the nucleus

32. Plant Cell Cytoplasm What fills the cell? a fluid called cytoplasm
What is suspended in the cytoplasm?
all of the organelles

33. Plant Cell Cell Membrane Cell Wall Large Vacuole Nucleus Mitochondria
Cytoplasm
Chloroplast
Ribosomes

34. Bacterial Cell Flagella What is the job of the flagella?
they help bacterial cells move around
How many flagella does a bacteria cell have?
some have one, others have many

35. Bacterial Cell Cell Wall
What is the job of the cell wall of a bacteria cell?
maintains the shape of the cell
Does the cell wall prevent things from entering or leaving the cell?
No, that is the job of the capsule, and cell membrane

36. Bacterial Cell Ribosomes Where are ribosomes found?
on the endoplasmic reticulum and floating in the cytoplasm
What is created by the ribosomes when they follow instructions from the nucleus?
proteins

37. Bacterial Cell Nucleoid
What collects in the central region of the cell?
DNA
Describe the region where DNA collects.
DNA gathers and clumps together toward the center of the cell

38. Bacterial Cell Plasma Membrane
Is the plasma membrane the only outer layer of a bacterial cell?
No, there are other layers
What is the job of the plasma membrane?
it controls what nutrients, ions, and waste enter and leave the cell

39. Bacterial Cell Cytoplasm What fills the cell? a fluid called cytoplasm
What is suspended in the cytoplasm?
all of the organelles

40. Bacterial Cell Cytoplasm Cell Membrane Nucleoid Cell Wall Ribosomes
Flagella
