Angiosperms
Angiosperms
Precambrian
flowering plants are part of a large group called angiosperms. They are the only (and most recently evolved group) to have flowers. Nonflowering plants are gymnosperms, seedless vascular plants (like ferns) and bryophytes.
It is uncertain what is meant by a "group". If you Google "youngest species" you find that polýploid hýbrid flowers are the newest and easiest to create, with Senecio eboracensis at 40 years ago. The cross sign × is supposed to be written before the specific epithet but isn't represented in the paper.
No, my aloe plant has not frozen recently.
No, grass is not a protist. Grass is a flowering plant belonging to the plant kingdom. Protists are a diverse group of eukaryotic microorganisms that are not classified as plants, animals, or fungi.
flower. Flowers are the reproductive structures in angiosperms that have evolved relatively recently compared to other plant reproductive structures. They are specialized to attract pollinators and facilitate the process of pollination and fertilization.
Horsetails are not a seed plant because they are a seedless vascular plant and fall into the catergory pterophytes. According to the diversity of plants Seed Plants evolved in about 360 mya after Pterophytes (about 420 mya) . So in order for a plant to be a seed plant it should fall into the plant group of either Gymnosperm or Angiosperm.
Bacteria, and yeast cells, as well as protists
Embryophyte plants are beneficial because they are the group of plants that have evolved to reproduce via seeds, making them essential for ecosystems and providing oxygen, food, and habitats for other organisms.
algae
The ancestral group to all members of the Plant Kingdom is thought to be a group of freshwater green algae called Charophytes. These algae share many characteristics with land plants, such as similar cell structure and reproductive mechanisms. It is believed that plants evolved from these ancient green algae ancestors.
