Plant Life Cycle II
Seeded plants, like angiosperms and gymnosperms, have a special way of reproducing called alternation of generations.
In seeded plants, the sporophyte, the full-grown plant you see, is the dominant stage, making it the most visible and long-lasting part of the plant's life cycle.
The sporophyte produces spores, but instead of growing independently, these spores develop into tiny gametophytes within reproductive structures.
In flowering plants, male gametophytes form inside pollen grains, while female gametophytes develop inside the ovule within flowers. These gametophytes produce sperm and egg cells.
Gymnosperms, like pine trees, use cones. Male cones make pollen, while female cones contain ovules.
When pollen reaches an ovule, fertilization occurs. In both angiosperms and gymnosperms, a sperm cell fuses with an egg, forming a zygote, which grows into an embryo inside a seed.
When conditions are favorable, the seed germinates into a new plant, continuing the life cycle.
Unlike seedless plants, this method allows seeded plants to spread efficiently across various environments without relying on water for fertilization.
