A Plant’s Raw Materials

Question 1

What do plants need in order to perform photosynthesis and where do they get these materials?

Answer 1

Water obtained through roots, carbon dioxide from animal exhalation, and sunlight from the sun

Question 2

Once plants make their foods, how do they release energy from those foods?

Answer 2

When plants create glucose, they use cellular respiration to release energy from glucose.

Question 3

The most important minerals needed by plants are————compounds.

Answer 3

nitrogen

Question 4

explain the reactants (inputs) and products (outputs) of photosynthesis.e

Answer 4

The reactants are CO2, water, and sunlight, and the products are oxygen and glucose.

Question 5

f a plant can use light energy to make materials, why does it need sugar?

Answer 5

Plants need sugar for cellular respiration which creates energy

Question 6

what was the optimal color light for plant growth

Answer 6

blue light

Question 7

what is 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.
