Rom4ik [11]

Male cones grow near the lower region of the plant, while female cones are located near the top of the tree.

Sexual Reproduction in Gymnosperms :

The lifecycle of a gymnosperm is also characterized by the alternation of generations, just as the lifecycle of an angiosperm. In conifers, such as pines, the sporophyte is the part of the plant that is green and leafy, and the gametophytes, in both male and female, are found in the cones. Female cones are distinguishable from male cones by their bigger size and their location closer to the crown of the tree. Male cones, on the other hand, are significantly smaller and can be found closer to the base of the tree. Because the pollen is dispersed and carried by the wind, it is impossible for a gymnosperm to self-pollinate due to the configuration of the plant.

Which term describes body structures in different organisms that have different outward appearances but develop from the same em

Nataly [62]

Answer:

The correct answer would be B) homologous.

Homologous organs refer to the set of organs which have different appearance and function but share common anatomy due to common ancestry.

For example, the forearm of human, forelimb of the horse, wing of a bat, wings of birds, and seal's flipper share common underlying anatomy. They are made up of same sets of bones (humerus, radius, ulna, carpels, metacarpals, and phalanges).

These organs are adapted to perform different functions in an environment.

It is also observed that these organs developed in the same manner in the embryo and from similar origins.
