AP BIOLOGY

Detailed explanation-1: -In seedless vascular plants, such as ferns and horsetails, the plants reproduce using haploid, unicellular spores instead of seeds. The spores are very lightweight (unlike many seeds), which allows for their easy dispersion in the wind and for the plants to spread to new habitats.

Detailed explanation-2: -Numerous seedless plants reproduce asexually through the vegetative, budding, cutting, fragmentation, layering, and micropropagation methods.

Detailed explanation-3: -Plants that reproduce by spores Ferns, mosses, liverworts and green algae are all plants that have spores.

Detailed explanation-4: -Where do seedless vascular plants live? Surviving descendants of early vascular plants include clubmosses and ferns. There are 1, 200 species of clubmoss and more than 20, 000 species of fern. Both types of vascular plants are seedless and reproduce with spores.

Detailed explanation-5: -Seedless plants can reproduce asexually or sexually. Some seedless plants, like hornworts and liverworts, can reproduce asexually through fragmentation. When a small fragment of the plant is broken off, it can form a new plant.
