Which of the following is true of fertilization in conifers? (2 points) The female cone releases its seeds and new gametophytes
9966 [12]

Answer:

The correct answer would be "The female cone releases its seeds and new sporophytes grow".  

Conifers are sporophytes with two types of cones; pollen cones and ovulate cone.

The pollen cones are smaller in size and produce microspores which would develop into the pollen grains.

The ovulate cones are larger in size which produce megaspores which would develop into ovule.

The two gametes fertilized to produce a diploid zygote which develops into the embryo.

The fertilization takes place in the ovule and thus, embryo or seed is developed in the female cone.

The female cone then releases its seed which grows into a new sporophyte.

Woody plants, such as trees, tend to have more genetic diversity, on the whole, than vascular plants, such as grasses. ... Part of the diversity is due to the size of each species' geographic range and how far they can move their genetic information, for example through wind pollination or animal seed dispersers.
