Photosynthesis Flashcards
What is the first useful product formed as a result of photosynthesis?
GLUCOSE
Which substances are transported in the phloem?
AMINO ACIDS & SUCROSE
Which product of photosynthesis moves out of a green leaf through its stomata?
OXYGEN
Which form of energy is stored within glucose molecules made during photosynthesis?
CHEMICAL
Which cell types in the leaf do not contain chloroplasts?
xylem, phloem and epidermal cells eg. guard cells
Which substances do xylem take to leaves?
A water and carbon dioxide
B water and mineral ions
C carbon dioxide and oxygen
and mineral ions
D carbon dioxide and
oxygen and water
Water and minerals
Which statement describes the net movement of CO2 particles during photosynthesis?
A from higher to lower
concentration down a
concentration gradient
B from higher to lower
concentration against a
concentration gradient
C from lower to higher
concentration down a
concentration gradient
D from lower to higher
concentration against a
concentration gradient
from higher conc. in atmosphere to lower conc. inside mesophyll cells concentration down a
concentration gradient
The list shows features of a plant leaf.
1 air spaces between spongy
mesophyll cells
2 chloroplasts in mesophyll
cells
3 contains a natural
insecticide
4 xylem vessels close to
mesophyll cells
Which features are adaptations for photosynthesis?
A 1, 2 and 3
B 1, 2 and 4
C 1, 3 and 4
D 2, 3 and 4
1 air spaces between spongy
mesophyll cells
2 chloroplasts in mesophyll
cells
4 xylem vessels close to
mesophyll cells
What is an example of a tissue?
A a chloroplast
B the palisade mesophyll
C a neuron
D the pancreas
The palisade mesophyll. (Tissue is a group of similar cells functioning together to carry out a particular function).
In which process is oxygen a waste product?
Photosynthesis
6CO2 + 6H2O = C6H12O6 + 6O2 (waste product)
