What do Cells do?

Ever wonder why you can’t fall asleep after eating a bag of sugar before bed???

Your cells are CONSTANTLY PRODUCING ENERGY!

Ever wonder why you have to pee in the middle of the night after you drink a glass of milk before bed?

Your cells are CONSTANTLY PRODUCING WASTE!!!


Label the following cell

THE MOST IMPORTANT THING ABOUT CELLS IS:

  • Cells produce energy

  • Cells produce waste

  • Cells are vital for life.

    They literally DO EVERYTHING!


Where is the energy produced

Where is the Energy Produced?

Where is the energy produced again?

Where is the waste stored?


Label the following cell

Energy is required for ALL CELLULAR ACTIVITY related to digestion, transport, repair of damage, and reproduction.

Plant cells have chloroplasts which contain chlorophyll which is in charge of converting carbon dioxide, water, and nutrients from the soil into SUGAR!


Label the following cell

But Miss. Corelli? How in the world do food/gases and waste get in and out of the cell!?!?!?


The flow of materials in and out of the cell

The flow of materials in and out of the cell

When it is wet and windy outside, what type of clothing would you choose to wear?

a. cotton

b. plastic

c. denim

Your choice will effect whether or not you will also be wet and cold. Certain materials will allow water and air to pass through easily, whereas others will not.


The flow of materials in and out of the cell1

The flow of materials in and out of the cell

When it is wet and windy outside, what type of clothing would you choose to wear?

a. cotton  permeable

b. plastic  impermeable

c. denim  permeable

None of the choices are correct.

Since plastic is impermeable, it may keep you nice and dry, but you will be very hot and sweaty inside.

You need a material that will let air out, but keep you dry.


Label the following cell

Such material is SELECTIVELY PERMEABLE.

The cell wall/cell membrane is SELECTIVELY PERMEABLE.

Look at this strainer.


Label the following cell

The cell wall and cell membranes will allow in certain substances in and others not:

WaterSodium (salt)

OxygenHydrogen

CarbohydratesPotassium

(SUGARS)

What other examples can you come up with?


Movement

Movement

The movement of substances in and out of the cell is called: cellular transport.;

  • Diffusion: movement of gas/liquid particles from an area of higher concentration to an area of lower concentration. (recall the bottle experiment)

  • Osmosis: diffusion involving water particles. This is more noticeable in plants.

Cell lab on thursday

Cell lab on Thursday!

Please bring in a carrot stick/celery stick.

Exam questions:

  • Describe permeable in your own words.

  • Use the term “selectively permeable” in a sentence that demonstrates its meaning.

  • When you put your groceries away, you forgot to put the celery in the refrigerator. When you found it on the counter, it was soft and limp. How could osmosis help the celery? Explain what you would do and why it would work.


How does the cell make energy

How Does the Cell Make Energy?

Where does all the particles go after they are in the cell?
