PARTS OF THE CELL

Part Two!

ROAD check

Which of the following would be an example of a prokaryotic cell?1. A blood cell2. A bacteria cell3. A plant cell4. A muscle cell

ROAD check

What kind of cells are eukaryotic cells?1. Plant and animal2. Bacteria and plant3. Animal and bacteria4. Animal cells only

ROAD check

You are a scientist trying to study a new form of life. You extract DNA from the cell’s nucleus. What type of cell could this be?

1. A. Prokaryotic2. B. Eukaryotic3. C. Both4. D. Neither

Where are we going?

Now that y’all are college bound experts at the difference between prokaryotic and eukaryotic cells, we’re going to step it up a notch and be able to tell the difference between plant and animal cells.

Where are we going?

Quick check: both plant and animal cells are (prokaryotic or eukaryotic)?

Where are we going?

But in order to know the difference between plant and animal cells, we need to know about 4 additional organelles!

By the end of the day..

Achievers on the ROAD to college will be able to describe the nuclear membrane, vacuole, chloroplast and mitochondria.

Achievers on the ROAD to college will be able to answer our question of the day

QUESTION OF THE DAY…

How can plants go without water for days but humans will die without water after 24 hours?

Organelles are smaller structures that carry out specific functions within the cell.

Organelles – Review!

WHAT YOU ALREADY KNOW

Cell Membrane- The cell membrane controls what can come in and out of a cell.

- Everything the cell needs-from food to oxygen-enters and leaves through the cell membrane.


Cell WallREMEMBER: ONLY IN PLANT CELLS!!

Made of a VERY tough material

Protects and supports the cell


NucleusThe nucleus is like the cell’s control center

It directs every activity that happens in the cell

REMEMBER: ONLY EUKARYOTES HAVE A TRUE NUCLEUS

ROAD check

If only eukaryotic cells have a true nucleus, where do you find DNA in a prokaryotic cell?

Nuclear Membrane

Works just like the cell membrane but around just the nucleus instead of around the whole cell!

(1)Protects and controls what goes in and out of the nucleus

Mitochondria

(2)Powerhouse of the cell Produce the (3)energy the cell needs to carry out its many functions

Muscle cells and cells that need to be very active have a large number of mitochondria

Chloroplasts

Capture energy from (4)sunlight

They use this energy to produce food for the cell

Chloroplasts give plants their green color

Vacuoles

(5)Store food and (6)water

Huge in (7)plant cellsSmall in animal cells

Vacu

ole

Write this down and study!

•Cell Theory: 1. All living things are

made of one or more cells

2. The cell is the most basic unit of life

3. All existing cells are produced by other living cells

ROAD check

•Why might a plant cell need a big vacuole, more so than an animal cell?•Hint – think about what YOU do when you are thirsty. Can plants do that?

ROAD check

What type of cell do you think you would find chloroplasts in?1. A. Animal cells2. B. Plant cells3. C. Both4. D. Neither

ROAD check

Marcus is building a model of a cell. He uses a big grape to represent the nucleus and peas to represent the chloroplasts. Marcus used jello to fill in between the nucleus and the peas. What does the jello represent?1. Cell membrane2. Cytoplasm3. Nucleus4. Cell Wall

ROAD check

_____ is the brain or control center of a cell.1. Cell membrane2. Cytoplasm3. Nucleus4. Cell Wall

ROAD check

What would be a good conclusion as to why plants are green?1. Because the chlorophyll inside the

chloroplasts is green.2. Because the nucleus is green.3. Because the outside of the leaves are green.4. Because the water plants soak up is dirty.

ROAD check

Which of the following produces energy for the cell?

1. Vacuole2. Nucleus 3. Cytoplasm4. Mitochondria

ROAD check

Which type of cell has a true nucleus?

1. Prokaryote2. Eukaryote3. Both4. Neither

ROAD check

You are a scientist looking at a cell and you see that it has a cell wall and chloroplasts. What kind of cell are you looking at?

1. Animal cell2. Human Cell3. Brain Cell4. Plant Cell

Independent Practice

Foldable One organelle Includes:

what type of cell you find it in

Details (pgs. 72-75)

a drawing

Independent Practice: GRADEDAnswer the following questions:

1.) Pick an organelle2.) Is it found in prokaryotes or eukaryotes?

3.) What does your organelle do? Use pages 72-75 for help and your notes

4.) Drawing of your Organelle!

EXAMPLE: Cell membrane can be found in both prokaryotic and eukaryotic cells.

Controls what comes in and out of the cell
