AP BIOLOGY

Detailed explanation-1: -The two main ways that flowering plants and conifers reproduce are sexual reproduction by means of seeds and asexual reproduction by means of separating and rooting part of a plant, cloning the mother plant.

Detailed explanation-2: -Conifers grow cones to reproduce instead of flowers or fruits. Scales grow on the outside of the cones. Some species of conifer grow male and female cones on the same tree, while others grow male and female cones on separate trees. The male cones, which are smaller than the female cones, produce pollen.

Detailed explanation-3: -The mechanisms of vegetative reproduction in conifers include layering, epicormic buds, and root suckers. Layering is the formation of roots from a branch in contact with the soil. Epicormic buds are dormant buds beneath a tree’s bark.

Detailed explanation-4: -All conifers are pollinated by wind. Pollen may be produced in enormous quantities, particularly by species of true pine (Pinus), which can blanket the surface of nearby lakes and ponds with a yellow scum of pollen (the pollen can cause allergies in humans).
