Introduction to Photosynthesis

Question 1

Chemical Reaction

Answer 1

The process by which one or more substances change to produce one or more substances.

Question 2

Chloroplast

Answer 2

A membrane-bound organelle in plants that is the site of photosynthesis.

Question 3

Energy

Answer 3

The ability of a system to do work; required for changes to happen in a system.

Question 4

Glucose

Answer 4

A sugar composed of six carbon that is the preferred energy source for most cells; produced by photosynthesis.

Question 5

Matter Cycle

Answer 5

The movement of elements or molecules through a repeated sequence of events.

Question 6

Microorganism

Answer 6

An organism that is too small to be seen by the naked eye.

Question 7

Photosynthesis

Answer 7

A chemical reaction during which plants convert radiant
energy from the Sun to chemical energy; the reaction
converts carbon dioxide and water into sugar (glucose).

Question 8

Phytoplankton

Answer 8

Microorganisms that absorb carbon from the
water during photosynthesis; pivotal for the
carbon cycle in marine environments

Question 9

Products

Answer 9

A substance produced during a chemical reaction

Question 10

Reactant

Answer 10

A substance that takes part in and undergoes

change during a reaction

Question 11

Autotroph

Answer 11

An organism that can make its own food, being able to produce complex organic compounds such as proteins and carbohydrates.

Question 12

Biochemistry

Answer 12

The study of chemical reactions in living organisms, the chemistry of life.

Question 13

Chloroplast

Answer 13

The organelles within plant cells where photosynthesis takes place, harnessing energy from sunlight to make sugars.
