• stored energy

• renewable energy

• The ability to do work.

Multiple Choice

Animals obtain their energy from ....... 

• Food
• Sun
• Air
• Uranium

Multiple Choice

Energy from _____ helps with the process of photosynthesis.

• the Sun
• water
• food
• the ground

Multiple Choice

What is chemical energy?

• The energy stored in the bonds of molecules; fuel energy

• The energy stored in the nucleus of an atom

• gasoline in a car

• The heat energy of substances due to the atoms and molecules vibration

Multiple Choice

What is the function of ATP in living things?

• provides energy for cells
• stores genetic information
• provides structure in the nucleus

ATP

adenosine triphosphate

Multiple Choice

Which structures shown in the Figure make up the ADP molecule?

• A and B

Key Question 2

How does photosynthesis capture energy from the sun to generate food for the plant?

Multiple Choice

What structure within a plant cell does photosynthesis?

• Sap vacuole

Chloroplast

In plants, photosynthesis takes place inside chloroplasts. Each chloroplast is filled with grana, which are stacks of thylakoid membranes. Inside the thylakoid membranes, chloroplyll is stored.

Multiple Choice

Chloroplasts are...

• Structures of animal cells to produce ATP
• Organelles where lipids are elaborated
• Specialized structures of plants where food is made
• Waste organelle of plants

Multiple Choice

What chemical found in plant cells is able to use the energy in sunlight to make food?

• cytoplasm
• chlorophyll
• lactic acid
• sulfuric acid

Multiple Choice

Chlorophyll causes many plants to be what color?

• yellow
• green
• brown
• orange

Multiple Choice

Light

What is pigment?

• The entire range of light, including visible and invisible light

• A special chemical that absorbs some colors and reflects others

• The tool you need to see the spectrum of colors in white light

• The shadow that is formed on a wall when light is blocked

Multiple Choice

Leaves look green because.....

• they eat their vegetables

• to blend into their environment

• they contain a molecule named chlorophyll

• they are sick

Multiple Choice

A leaf is green. What does this tell you about the light that is being absorbed?

• The light is a UV ray.

• The light is not a part of the light spectrum.

• All colors are reflected except green.

• All colors are absorbed except green
