Detailed explanation-1: -Gymnosperms: They are flowerless plants, which generate naked seeds and cones. Examples are ginkgo, sago palm, etc. Angiosperms: They are the flowering plants, which possess vascular bundles with phloem and xylem tissues, and the seeds are covered. Examples are rose, hemp, orchids, etc.

Detailed explanation-2: -Final answer: The division of plants into gymnosperms and angiosperms terminates with the suffix ‘sperm’. It means that they both produce seeds.

Detailed explanation-3: -The four main divisions of gymnosperms are Coniferophyta, Cycadophyta, Ginkgophyta, and Gnetophyta. Gymnosperms are often found in temperate forest and boreal forest biomes. Common types of gymnosperms are conifers, cycads, ginkgoes, and gnetophytes.

Detailed explanation-4: -These divisions are based on the following criteria: • Differentiated/Undifferentiated plant body. • Presence/absence of vascular tissues. • With/ without seeds. • Naked seeds/seeds inside fruits. More items
