Photosynthesis

Question 1

Biochemical Biochemical process in which the organelle shown in the diagram plays an important role
What is it

Answer 1

Photosynthesis

Question 2

NAME of the structure in which the light dependent reaction takes place and reason

Answer 2

Granum

Contains chlorophyll
Chlorophyll absorbs light energy

Question 3

Name the 2 stages of an important biological process which takes place within the organelle

Answer 3

Light phase/Light dependant phase
Dark phase /Light independent

Question 4

Explain the process that takes place in the grana during daylight 5 points

Answer 4

The light phase takes place in the grana of the chloroplast
which contain chlorophyll
- the chlorophyll absorbs light energy
Part of the light energy is used to form ATP
Part of the light energy is used for splitting water ~ (photolysis)

Question 5

Explain whether environmental temperatures could either slow down or stop the process that takes place in the chloroplast

Answer 5

At high temperatures, the protein molecules of the enzymes become denatured

• Therefore, the enzymes become functionless

Question 6

Give the function of the starch sack

Answer 6

It stores starch
