1
Q

What is the process of photosynthesis using words and symbols?

A

Carbon dioxide, water and radiant energy –> glucose and oxygen.

2
Q

What are the 5 required raw materials for photosynthesis?

A

CO2, H2O, Radiant energy, Chlorophyll, Enzymes.

3
Q

Where do the required raw materials, for photosynthesis, come from?

A

CO2 = atmosphere; H2O = soil; radiant energy = sun; chlorophyll = chloroplasts of green plants.

4
Q

What are the 2 products of photosynthesis?

A

Glucose and oxygen

5
Q

Where do the 2 products of photosynthesis come from?

A

Glucose = stored in the plant as starch; Oxygen = released into the atmosphere.

6
Q

What are the 5 parts of a typical chloroplast?

A

Double membrane, granum, intergranum, stroma, lamela

7
Q

Where does the light phase occur?

A

In the grana of the chlorplasts, in the presence of light, light dependent

8
Q

Where does the dark phase occur?

A

In the stroma of the chloroplasts, in light or darkness and is light independent

9
Q

Give a brief description of photolysis

A

Water molecules are split up into energy-rich H-atoms and Oxygen atoms

10
Q

Give a description of phosphorylation

A

The energy carrier ATP is also formed from ADP to be used in the dark phase

11
Q

In which phases, light or dark, does the Calvin Cycle occur?

A

Dark phase

12
Q

What is the role of ATP as an important energy carrier in the cell

A

Energy is needed for cell metabolism, ATP is then broken into ADP which releases energy.

13
Q

What is the importance photosynthesis (4 main ideas)?

A

Keeps oxygen concentration constant, keeps CO2 level constant, provides food, makes chemical energy available for cell functioning.
