photosynthesis and respiration

Question 1

photosynthesis

Answer 1

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

ATP

Answer 2

ATP captures chemical energy obtained from the breakdown of food molecules and releases it to fuel other cellular processes.

Question 3

Starch

Answer 3

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.

Question 4

Respiration

Answer 4

the action of breathing

Question 5

Producer

Answer 5

Producers are any kind of green plant. Green plants make their food by taking sunlight and using the energy to make sugar. The plant uses this sugar, also called glucose to make many things, such as wood, leaves, roots, and bark.

Question 6

Autotroph

Answer 6

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

Question 7

Chloroplast

Answer 7

a green pigment, present in all green plants and in cyanobacteria, responsible for the absorption of light to provide energy for photosynthesis. Its molecule contains a magnesium atom held in a porphyrin ring

Question 8

Glucose

Answer 8

Glucose is the main type of sugar in the blood and is the major source of energy for the body’s cells. Glucose comes from the foods we eat or the body can make it from other substances

Question 9

Heterotroph

Answer 9

an organism deriving its nutritional requirements from complex organic substances

Question 10

Monosaccharide

Answer 10

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

Question 11

Polysaccharide

Answer 11

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