the wind
a beetle
a fly
a butterfly
26, CAM and C4 photosynthesis
help produce extra ATP in the light-dependent reactions.
2)Reduce the chances that Rubisco will bind with O2.
Reduce the chances that Rubisco will bind with CO2.
Help produce extra NADPH in the light-dependent reactions.
28, Of the following which is not an input of photosynthesis?
Light
Water
Glucose (sugar)
CO2
29, in gymnosperms, seeds are produced in
Fruit
Sori
Con
Setas
Explanation / Answer
25. Pollination is the transfer of pollen from the anther of one flower to another (or within the same flower). Normally petals attract insects that aid pollination but I a flower has reduced or no petals like grass then it is likely to be pollinated by 1) the wind.
26. The C4 and CAM pathways are two adaptations—beneficial features arising by natural selection—that allow certain species to minimize photorespiration. These pathways work by ensuring that Rubisco always encounters high concentrations of CO2 making it unlikely to bind to O2
Answer is 2) Reduce the chances that Rubisco will bind with O2
28. Glucose is not an input of photosynthesis
6CO2 + 6H2O + light energy ?C6H12O6 + 6O2.
It is clear from the above reaction that glucose is a product of photosynthesis.
29. In gymnosperms , seeds are produced in cones.
Gymnosperms are plants that make seeds, but don't make flowers and fruits. They include pine trees, Ginkgo trees, and cycads. Gymnosperms have cones in which seeds are formed.
