Detailed explanation-1: -Both gymnosperms (cone-bearing plants) and angiosperms (flowering plants) produce pollen as part of sexual reproduction. In gymnosperms pollen is produced in microsporangiate cones (male cones or pollen cones), while in angiosperms pollen is produced in the anthers (part of the stamen within the flower).
Detailed explanation-2: -Both groups produce seed, but the seed of angiosperms is enclosed within a fruit. The names are from Greek – gymnosperm meaning “naked seed, ” angiosperm combining “vessel” and “seed”.
Detailed explanation-3: -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-4: -Most gymnosperms produce seeds in structures called cones or strobili (singular strobilus; Figure 8.1. 2). Cones evolved from modified leaves, and they can either be male cones that produce pollen, or female cones that produce ovules.
