Photosynthesis and Respiration

Question 1

Photosynthesis

Answer 1

Photosynthesis is a process used by plants and other organisms to convert light energy into chemical energy that, through cellular respiration, can later be released to fuel the organism’s metabolic activities.

Question 2

Producer

Answer 2

an organism that produces its own food.

Question 3

Monosaccharide

Answer 3

the basic compounds that serve as the building blocks of carbohydrates.

Question 4

Polysaccharide

Answer 4

a carbohydrate that can be decomposed by hydrolysis into two or more molecules of monosaccharides.

Question 5

Starch

Answer 5

an organic chemical that is produced by all green plants.

Question 6

ATP

Answer 6

the principal molecule for storing and transferring energy in cells.

Question 7

Autotroph

Answer 7

an organism that can make its own food by synthesizing organic nutrients from inorganic materials, using energy from sunlight or a chemical source to drive the process.

Question 8

Cellular Respiration

Answer 8

the process by which organisms combine oxygen with foodstuff molecules, diverting the chemical energy in these substances into life-sustaining activities and discarding, as waste products, carbon dioxide and water.

Question 9

Chloroplast

Answer 9

an organelle within the cells of plants and certain algae that is the site of photosynthesis, which is the process by which energy from the Sun is converted into chemical energy for growth.

Question 10

Glucose

Answer 10

A simple sugar that is the chief source of energy.

Question 11

Heterotroph

Answer 11

an organism that obtains nutrients by consuming other organisms.
