Gymnosperms ("naked seed") are a diverse group of seed plants and are paraphyletic. Unlike such nonvascular plants as the bryophytes, in which all cells in the plant body participate in every function necessary to support, nourish, and extend the plant body (e.g., nutrition, photosynthesis, and cell division), angiosperms have evolved specialized cells and tissues that carry out these functions and have further evolved specialized vascular tissues (xylem and phloem) that translocate the water and nutrients to all areas of the plant body. Plants had to figure out how to reproduce and disperse their offspring without water. Both mosses and ferns have swimming sperm that require moisture to reach an egg. The first plants to do this were bryophytesplants without vascular systems. We'll look more closely at reproduction in angiosperms, which are unique among plants for three defining features: they have flowers, they have fruit-covered seeds, and they reproduce via a process called double fertilization..
