Photosynthesis and Respiration

Question 1

Chloroplast

Answer 1

A plastid that contains chlorophyll and in which photosynthesis takes place.

Question 2

ATP

Answer 2

Adenosine triphosphate

Question 3

Autotroph

Answer 3

an organism that is able to form nutritional organic substances from simple inorganic substances such as carbon dioxide.

Question 4

Cellular Respiration

Answer 4

Cellular respiration is a set of metabolic reactions and processes that take place in the cells of organisms to convert chemical energy from oxygen molecules or nutrients into adenosine triphosphate, and then release waste products.

Question 5

Glucose

Answer 5

a simple sugar which is an important energy source in living organisms and is a component of many carbohydrates.

Question 6

Heterotroph

Answer 6

an organism deriving its nutritional requirements from complex organic substances.

Question 7

Photosynthesis

Answer 7

the process by which green plants and some other organisms use sunlight to synthesize foods from carbon dioxide and water. Photosynthesis in plants generally involves the green pigment chlorophyll and generates oxygen as a byproduct.

Question 8

Producer

Answer 8

an organism that produces organic compounds from simple substances such as water and carbon dioxide; an autotroph.

Question 9

Monosaccharide

Answer 9

any of the class of sugars (e.g., glucose) that cannot be hydrolyzed to give a simpler sugar.

Question 10

Polysaccharide

Answer 10

a carbohydrate (e.g. starch, cellulose, or glycogen) whose molecules consist of a number of sugar molecules bonded together.

Question 11

Starch

Answer 11

an odorless, tasteless white substance occurring widely in plant tissue and obtained chiefly from cereals and potatoes. It is a polysaccharide which functions as a carbohydrate store and is an important constituent of the human diet.
