Bell Ringer – Monday!! What organelle does a eukaryote cell have and a prokaryotic cell does not? Which is a prokaryotic and which is a eukaryotic? Plant Human

Bell Ringer – Review 1. What organelle does a eukaryotic cell have and a prokaryotic cell does not? “PRO means NO and EU means NEU” 2. Which is a prokaryotic and which is a eukaryotic? Both plants and humans/animals are eukaryotic organisms

Parts of the cell Part Two!

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? A. Prokaryotic B. Eukaryotic C. Both 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 – Review! Organelles are smaller structures that carry out specific functions within the cell.

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.

WHAT YOU ALREADY KNOW Cell Wall REMEMBER: ONLY IN PLANT CELLS!! Made of a VERY tough material Protects and supports the cell

WHAT YOU ALREADY KNOW Nucleus The 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

(5)Store food and (6)water Vacuoles (5)Store food and (6)water

Huge in (7)plant cells Small in animal cells

Vacuole

Write this down and study! Cell Theory: All living things are made of one or more cells The cell is the most basic unit of life 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 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.

Independent Practice Foldable One organelle Includes: what type of cell you find it in Details (pgs. 72-75) a drawing

Independent Practice: GRADED Answer the following questions: 1.) Pick an organelle 2.) 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
