Questions and Answers
Succession - Answer>>The gradual, directional change of a
community over time, during which the organisms within an
ecosystem change the conditions to allow better adapted
organisms to colonise the area, replacing it's current inhabitants.
Primary succession - Answer>>Occurs in a completely lifeless
habitat
Secondary succession - Answer>>Occurs in a devastated
ecosystem
Climax community - Answer>>The endpoint of succession
Pioneer species - Answer>>The first species to colonise an
area, tends to be very specialised
1)Frame quadrat 100 squares
2)Selecting random coordinates (random sampling)
3)Record number of named organism
4) Percentage cover
5) Repeat - Answer>>Study of ecology
Thylakoid - Answer>>Where does the light dependent reaction
occur
thylakoid membrane - Answer>>A system of interconnected,
flattened sacs with proteins embedded in the membranes
ATP and NADPH - Answer>>Products of the light dependent
reaction
, Stroma - Answer>>Where does the Calvin cycle occur
NADP, ADP and glucose - Answer>>Products of the Calvin
cycle
Chloroplast - Answer>>Where photosynthesis occurs
chloroplast structure - Answer>>Photosynthetic pigment found
in thylakoid membrane, double membrane called chloro envelope,
thylakoids are stacked up in the chloroplasts into grana and linked
together by lamellae
Absorbed by the photosynthetic pigments and converted to
chemical energy - Answer>>What happens to light energy when
it enters the chloroplast?
A series of redox reactions
ATP is released - Answer>>How do the electrons move along
the electron transport chain in photosynthesis?
Photophosphorylation - Answer>>Name for the synthesis of
ATP using light
Two hydrogen ions, one oxygen, two electrons - Answer>>What
is produced from the photolysis of water?
Combine with one hydrogen ion and NADP to form NADPH -
Answer>>What happens to the electrons when the leave the
electron transport chain (photosynthesis)
Six - Answer>>How many times does the Calvin cycle have to
happen to form one glucose molecule
