Conservation of Mass photosynthesis and cellular respiration

Conservation of Mass, Photosynthesis and Cellular Respiration

Multiple Choice

What evidence do we have that photosynthesis is occuring?

• bubbles

• light

• its alive

• water

Multiple Choice

What is the energy source for photosynthesis.

• sugar

• food

• light

Multiple Choice

Mixing baking soda in water increases the amount of what gas?

• oxygen

• carbon dioxide

• ozone

Multiple Choice

Which gas is produced by photosynthesis?

• oxygen

• carbon dioxide

• ozone

Multiple Select

Select all the reactants for photosynthesis.

• oxygen

• carbon dioxide

• glucoes

• water

Multiple Select

Select all the products for photosynthesis.

• oxygen

• carbon dioxide

• glucoes

• water

Multiple Choice

Select the organisms that use glucose made by photosynthesis.

• plants

• animals

• plants and animals

Multiple Choice

We know photosynthesis is a chemical change because

• it cant be put back

• its done with chemicals

• new substances form

Multiple Choice

The law of conservation of mass states "Mass cannot be created or destroyed, it only changes forms". How is the production of glucose made of Carbon, Hydrogen, and Oxygen an example of this law?

• the different compounds separate then combine and make a new compound

• they combine and some atoms are lost

• the elements are broken down then reformed

Multiple Choice

How does the amount of sugar affect how much gas yeast will release?

• more sugar=more gas

• more sugar=less gas

• less sugar=more gas

Multiple Choice

What was the control group in this experiment?

• the amount of yeast

• the amount of sugar

• the first bottle with no sugar

• the balloon

Multiple Choice

In this experiment students measured their gas output before and after exercise using a liquid called Bromothymol Blue. What gas are they exhaling that is causing the color change?

• Oxygen

• Carbon Dioxide

• Ozone

Multiple Choice

Are they producing more or less of that gas after exercising?

• more

• less

Multiple Choice

What gas do you think the students need to inhale to start the process of respiration?

• Carbon Dioxide

• Oxygen

• Hydrogen

• Helium

Multiple Select

Select all of the reactants for cellular respiration.

• Oxygen

• Carbon Dioxide

• Glucose

• Water

Multiple Select

Select all of the products for cellular respiration.

• Oxygen

• Carbon Dioxide

• Glucose

• Water

• ATP (energy)

Multiple Choice

Select the organisms that have cells that go through cellular respiration.

• plants

• animals

• plants and animals

Multiple Choice

Why do organisms go through cellular respiration?

• to recycle Carbon Dioxide

• to use up their Oxygen

• to convert glucose (sugar) into energy

Multiple Choice

Cellular respiration is a chemical change. What could be done to speed up the process of cellular respiration?

• cool down the cells

• provide more carbon dioxide

• heat up the cells
