Photosynthesis

Question 1

Organisms that make their own food. (self-feed)

Answer 1

Autotroph

Question 2

Organisms who consume other organisms in order to create energy.

Answer 2

Heterotroph

Question 3

The production of organic carbon compounds using light energy in two steps.
water + carbon dioxide - oxygen + glucose
6 H2O + 6 CO2 - 6 O2 + C6H12O6

Answer 3

Photosynthesis

Question 4

Some organisms like bacteria use inorganic compounds such as H2S which comes from hydrothermal vents.

Answer 4

Chemosynthesis

Question 5

Feeds on living or recently killed organisms by ingestion.

Answer 5

Consumer
Bears eat fish that just died because it caught the fish. If you leave the the fish on floor and it rots the worms will eat since the bear doesn’t want it.

Question 6

An organism that shoots out digestive enzymes into dead stuff and then absorbs the juice

Answer 6

Saprotroph
(fungi)

Question 7

An organism that eats dead organic matter and digests it internally.

Answer 7

Detritivore
(worm)

Question 8

Complex organic carbon compounds build the structure of their cells and carry out life processes

Answer 8

Carbohydrates(Sugars)
ex: glucose

Question 9

• Split water producing oxygen gas (O2)
• Oxygenproduce in photosynthesis is from the photolysis of water
  2H2O (I) - 4e + 4H + O2(g)

Answer 9

Light-dependent reaction
Light and water = oxygen
Chemical energy

Question 10

The reaction consumes chemical energy from the light-dependent reaction from step 1 and CO2 to produce glucose (sugar)

Answer 10

Light-independent reaction
Chemical energy + carbon dioxide = glucose

Question 11

Chemical bonds are broken as a result of the transfer of light energy

Answer 11

Photolysis

Question 12

Cells which contain chlorophyll and other light-sensitive pigments that capture solar energy. In the presence of carbon dioxide, such cells are able to convert this solar energy into energy-rich organic molecules, such as glucose.

Answer 12

Photosynthetic cells

Question 13

Inside the photosynthetic cell, the leaves of the plant perform both light and dark reactions. These organelles are green dots shown above.

Answer 13

Chloroplasts
It has an internal structure with a large surface area which allows for efficiency and a high rate of photosynthesis.

Question 14

The chemical compound that absorbs energy from visible light.
- Chlorophyll (green)
- Xanthophylls (yellows)
- Carotenoids (oranges)
- Anthocyanins (reds)

Answer 14

Pigments

Question 15

The main pigment found in photosynthesizing organisms

Answer 15

Chlorophyll
