Question [CLICK ON ANY CHOICE TO KNOW THE RIGHT ANSWER]
Angiosperms are characterized by ____ and gymnosperms are characterized by ____
A
cones; flowers
B
cones; spores
C
spores; cones
D
flowers; cones
Explanation: 

Detailed explanation-1: -Like gymnosperms, angiosperms are seed-producing plants. They are distinguished from gymnosperms by characteristics including flowers, endosperm within their seeds, and the production of fruits that contain the seeds.

Detailed explanation-2: -Angiosperms and gymnosperms both utilize seeds as the primary means of reproduction, and both use pollen to facilitate fertilization. Gymnosperms and angiosperms have a life cycle that involves the alternation of generations, and both have a reduced gametophyte stage.

Detailed explanation-3: -Angiosperms do not produce cones and produce flowers/fruits instead. Gymnosperms are vascular plants that produce cones. Cones have their seeds exposed on the surface of their leaf-like structures instead of the seeds being enclosed in an ovary.

Detailed explanation-4: -Angiosperms, also called flowering plants, have seeds that are enclosed within an ovary (usually a fruit), while gymnosperms have no flowers or fruits, and have unenclosed or “naked” seeds on the surface of scales or leaves. Gymnosperm seeds are often configured as cones.
