8-2 photosynthesis

Identify the letters of the region of the visible spectrum in which chlorophyll absorbs light very well

Blue-violet region, red region

Photosynthesis uses the energy of sunlight to convert water and carbon dioxide into oxygen and high energy.........

Carbohydrates

Right the complete equation for the process that is called the changes in step four. You may use words are symbol in your equation

Carbon dioxide + water -> light glucose + oxygen

Write the overall equation for photosynthesis using words.

Carbon dioxide and water, using sunlight, yield sugar and oxygen

The water change from blue to yellow when a student blew into it. Identify the compound that cause the water to change from blue to yellow

Carbon dioxide change the water from blue to yellow

At what distance from the light source what is the greatest number of bubbles produced?

Five CM because it is producing more photosynthesis

If the student later tested the air bubbles collected in the test tube, what would she find they are made of?

Oxygen

Explain why the water turned blue again when the beaker with the water weed was under the bright light. In your explanation identify the process that causes the change

Photosynthesis took place. During the process the plant used carbon dioxide as a reactant, and released oxygen which turn the water blue again.

Plants gather the sunlight energy with light absorbing molecules called...........

Pigments

What does photo synthesis require in addition to water and carbon dioxide

Sunlight and chlorophyll

Explain why there are bubbles on the waterweed leaves

The bubbles are oxygen, a product of photosynthesis

What did the students data show?

The closer the light source the more bubbles

What occurs in the process of photosynthesis?

autotrophs use energy from sunlight, water, and carbon dioxide to produce high-energy sugars and oxygen.

What is the principal pigment of plants

chlorophyll
