Molds And Mushrooms
31. Molds and mushrooms are similar in the process of reproduction. They both reproduce asexually through the process of sporulation. Why these organisms reproduced anywhere?
a. because the spores are lighted directly by the sun.
b. because the spores are transported by air and wind.
c. because the spores are very small and heavy.
d. because the spores are grafted to another plant.
32. In flowering plants, there are two events that lead to reproduction. What are these two events?
a. Fertilization and fission c. Pollination and fission
b. Pollination and fertilization d. Pollination and sporulation
33. Which of the following sequences shows the correct order of events that occur after an insect brings pollen to a flower?
