There are four main groups of land plants: bryophytes, pteridophytes, gymnosperms, and angiosperms. Fruits are derived from the maturing floral organs of the angiospermous plant and are therefore characteristic of angiosperms. Gymnosperms are seed plants adapted to life on land; thus, they are autotrophic, photosynthetic organisms that tend to conserve water. 4 Why are seed plants successful on land? This group is usually referred to as angiosperms because, as their name implies, their seeds are enclosed in a carpel (in a vessel). Some plants have also adapted to living in very dry conditions such as desert conditions. These adaptations became the foundation of modern plant anatomy. In addition, the flowering plants are the most economically important group of green plants, serving as a source of pharmaceuticals, fibre products, timber, ornamentals, and other commercial products.

[email protected] 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.
