I NEED HELP ASAP

Answers

Answer:

The correct answer is The gametophytes grow directly from the sporophyte.

Explanation:

Conifers are a group of plants that belong to what is called Pinophyta.

They abound in quantity in cold areas although many different types of this plant can also be found in tropical areas.

They are formed by live gemnosperm plants, this means that their seeds do not form in closed cavities but are "naked". These seeds are evergreen, this means that their leaves will not fall throughout the year and usually live for more than two years or produce other seeds again.

Gametophytes are haploid plants that are usually located in or below the soil and are responsible for producing gametes.

These grow directly from the sporophyte, which is the phase in which a plant reproduces by spores.

So we can say that the correct answer is The gametophytes grow directly from the sporophyte.

Answer:

The gametophytes grow directly from the sporophyte - third choice

Which choice is involved in both sexual and asexual reproduction?seeds


sperm


spores


eggs

Answers

The choice that is involved in both sexual and asexual reproduction is the spores that are in the third option, as the others are involved in sexual reproduction, such as the sperm, egg, etc.

What is the advantage of sexual reproduction over asexual reproduction?

Both types of reproduction have advantages, for example, if a mutation occurs and becomes genetic, the chance of getting the disease is lower in sexual reproduction than in asexual reproduction. The possibility of recombination and crossing over reduces the rate of genetic disorders in sexual reproduction, whereas in asexual reproduction, the mutation passes from one to the other.

Hence, the choice that is involved in both sexual and asexual reproduction is the spores that are in the third option, as the others are involved in sexual reproduction, such as the sperm, egg, etc.
