What are the products of

photosynthesis?carbon dioxide and water

oxygen

carbon dioxide and sugars

oxygen and sugars

PHOTOSYNTHESIS

That is That is Incorrect!Incorrect!

What happens during

photosynthesis?The cell uses oxygen to make food.

The cell uses the energy in sunlight to make food.

The cell uses glucose to make oxygen.

The cell uses the energy in sunlight to make carbon dioxide.

Photosynthesis, definition. Paul Fuqua. 2005. unitedstreaming. 20 February 2006 <http://www.unitedstreaming.com/>

WHOA! Think about

it again!

What product of photosynthesis do most

living things need to survive?

Sodium chloride

oxygen

chlorophyll

carbon dioxide

WOW!YOU ARE DOING GREAT!

QuitMONKEY-ING around and THINK about

it.

What happens during

respiration?Oxygen is released into the air.

Glucose is broken down, releasing energy.

Carbohydrates are released into the bloodstream.

Water and carbon dioxide are converted into energy.

WOW!YOU ARE DOING GREAT!

OOPS! I wonder if you plug in your brain

if it would help. Click the arrow

to try again.

How are photosynthesis and respiration related?

They have opposite equations.

They have the same equations.

They both produce carbon dioxide.

They both produce oxygen.

CORRECT!

Try it Again!Try it Again!Try it Again!

Respiration and photosynthesis keep the levels of carbon dioxide and oxygen in the atmosphere

fairly constant

constantly changing

constantly decreasing

constantly increasing

Fantastic! Respiration and

Photosynthesis do keep levels fairly

constant.

Keep “fishing” for the correct

answer.

Which term refers to the production of energy by a

cell without using oxygen?

photosynthesis

respiration

fermentation

fertilization

Great Job!

Don’t be a bug.

Try again!

What causes lactic-acid fermentation?

too little oxygen in muscle cells

too much oxygen in muscle cells

too much sugar in muscle cells

too little sugar in muscle cells

HOORAY !

It is a good thing that you

get to try again!

Cancer is a disease in which cells

grow and divide uncontrollably

die before they can mature

die during mitosis

stop producing DNA

You are going to Hollywood!You will be the next Science Idol!

YOOOU need to

try again!

Scientists think cancer begins

whena mutation occurs in DNA

a cell divides too slowly

cells stop growing

DNA replication stops

Fantastic!

KEEP ONKEEP ONTRYING!TRYING!

What is chemotherapy?

The use of drugs to kill cancer cells.

The use of surgery to remove cancer cells.

The use of drugs to prevent cancer from occurring.

The use of radiation to destroy cancer cells.

Chemotherapy is the use of drugs to kill cancer cells.

It is a good thing that you

get to try again!

What captures energy from light during photosynthesis?

solar cells

stomata

carbohydrates

chlorophyll and other pigments

Yeah !!!!!

I think you need

to try again!
