What is angiosperm plant?
Angiosperms and gymnosperms are the two major groups of vascular seed plants. Angiosperms, which are flowering plants, are the largest and most diverse group within the kingdom Plantae. With around 300,000 species, they represent approximately 80 percent of all the known green plants now living.

Gymnosperms appear in the fossilrecord about 319 million years ago. While not the first vascular plants, they were the first with pollen and seeds instead of spores. Seeds usually form within unisexual (separate male and female) strobili or cones. Pollen helped these plants spread genetic information across vast distances, while seeds protected the...
Angiosperms did not appear in the fossil record until about 150 million years ago, but within 50 million years they became the dominant type of plant. Flowers attract pollinators and contain the reproductive structures of an angiosperm. Flowers are either unisexual (male and female flowers) or bisexual (both male and female parts on a single flower...
Flowering plants have some advantages compared with gymnosperms: 1. More efficient water and nutrient transport 2. Better nutrition for embryo 3. Better protection for embryo Angiosperms have specialized cells called vessel elements that help them move water more quickly than in gymnosperms, which only have tracheids for moving water. Additionally,...
Both angiosperms and gymnosperms are vascular plants that produce seeds. Both have a sporophyte-dominated life cycle, which means most of their life cycle they are diploid (2n), with a short gamete-producing phase. Here are the differences between them:

Angiosperms have flowers, fruits, and animal pollinators, while gymnosperms have cones, naked seeds, and wind pollination.
Learn the key differences between angiosperms and gymnosperms, two types of seed-producing plants. Angiosperms have flowers, fruits, and endosperm in the seeds, while gymnosperms have no flowers or fruits, and have unenclosed or “naked” seeds on the surface of scales or leaves.
- Seasonal (die during autumn/fall).
- Enclosed inside an ovary, usually in a fruit.
Feb 2, 2023 · The two differences are: a) gymnosperms are non-flowering plants, and angiosperms are flowering plants, and b) seeds of gymnosperms are naked, while angiosperm seeds are enclosed within an ovary.

Apr 24, 2019 · Angiosperms and gymnosperms are two types of seed plants as shown by the suffix sperm which means “seed” in Latin. Gymnosperms first appeared on Earth during the Carboniferous period about 359-299 million years ago and they dominated the landscape by the Mesozoic era 251-65.5 million years ago.
Angiosperms have flowers that contain ovaries where seeds develop, while gymnosperms have cones that house their seeds. Additionally, angiosperms have enclosed seeds within fruits, providing protection and aiding in dispersal, while gymnosperms have naked seeds that are exposed on the surface of their cones.
