Which of the following correctly distinguishes between how a pine tree and an apple tree reproduce?
A
Pine trees reproduce asexually, while apple trees reproduce sexually.
B
Pine trees produce fruits for seed dispersal, while apple trees use cones.
C
Both pine trees and apple trees reproduce only through spores.
D
Pine trees reproduce using cones and seeds, while apple trees reproduce using flowers and fruits.
Verified step by step guidance1
Understand the reproductive structures of pine trees: Pine trees are gymnosperms, meaning they reproduce using cones. Male cones produce pollen, and female cones contain ovules that develop into seeds after fertilization.
Understand the reproductive structures of apple trees: Apple trees are angiosperms, meaning they reproduce using flowers. Flowers contain reproductive organs, and after fertilization, the ovules develop into seeds enclosed within fruits.
Compare the reproductive strategies: Pine trees rely on cones for seed production and dispersal, while apple trees use flowers for reproduction and fruits for seed dispersal.
Clarify the distinction between gymnosperms and angiosperms: Gymnosperms like pine trees do not produce fruits; their seeds are exposed on cone scales. Angiosperms like apple trees produce seeds enclosed within fruits, which aid in dispersal.
Conclude that the correct distinction is: Pine trees reproduce using cones and seeds, while apple trees reproduce using flowers and fruits.
