<h2>Angiosperms </h2>
Explanation:
Angiosperms are the most diverse group of plants, some statements which reflect angiosperm adaptations to life on land:
- Flowers attract animal pollinators carrying pollen from other plants of the same species
- Fruits aid in the dispersal of seeds by wind or by animals that carry or eat the fruits
- In many angiosperms, the male gametophyte contained in a pollen grain can be transported many miles away by wind or animal pollinators
- Floral parts of the sporophyte protect the reduced female gametophyte from drying out and from UV radiation
- Seeds protect and nourish plant embryos, and fruits protect the seeds
- Seeds enable plant embryos to be dispersed long distances from the parent plant via wind or animals
