Final answer:
Redwoods are monoecious, having both male and female reproductive organs on the same plant, and evergreen, retaining their leaves throughout the year. They are neither heterosporous nor homosporous, as they don't produce two distinct types of spores.
Step-by-step explanation:
Redwoods are monoecious and evergreen. Being monoecious means that they have both male and female reproductive organs on the same plant. Hence, they are both male and female, which enables them to self-fertilize. The term evergreen refers to the fact that redwoods retain their leaves throughout the year; they do not lose them in a specific season like deciduous trees do. Redwoods are not heterosporous as they do not produce two types of spores, male and female. Neither are they homosporous because they don't produce one type of spore that has both male and female characteristics.
