Angiosperms have adapted over the years to their environment. The angiosperms are the flowering plants. Our angiosperm friends have a huge amount of stomata (plural of stoma) and veins which really makes the most of their photosynthesis. And oxygen, which are for the transportation of water and minerals the. 1. Another significant evolutionary advancement over the nonvascular and the more primitive vascular plants is the presence of localized regions for plant growth, called meristems and cambia, which extend the length and width of the plant body, respectively. Within desert areas, species that frequently grow as gregarious solitary plants in herds are most striking. Plants, descended from aquatic green algal ancestors, first appeared on land more than 450 million years ago during or prior to the Ordovician period.This event preceded the colonization of land by four-footed animals (tetrapods), which occurred considerably later in the Devonian period (408 to 360 million years ago). Some of the characteristics of angiosperms include: All angiosperms have flowers at some stage in their life. To describe the life histories and related reproductive structures of gymnosperms and angiosperms.

Vascular tissues, roots, leaves, cuticle cover, and a tough outer layer that protects the spores contributed to the adaptation of plants to dry land. Plants that live in very dry conditions are called xerophytes. Angiosperms and gymnosperms both utilize seeds as the primary means of reproduction, and both use pollen to facilitate fertilization. internal fertilization. As a result, angiosperms are the most important ultimate source of food for birds and mammals, including humans. Some plants and trees (tracheophytes) have vascular tissue or well-developed conducting tissue through which water and solutes are transported to various parts of the plant. The M. polymorpha basic body plan consists of a flattened-sheet tissue reminiscent of leaves termed a 'thallus' (Figure 1A).

They are called flowering plants and are the largest as well as the most diverse group in the kingdom Plantae. The angiosperms comprise vascular seed plants. The Angiosperms or flowering plants have seeds covered by or enclosed within the fruit. These two characteristics allowed some gymnosperms and angiosperms to fully adapt to land conditions. The angiosperms came to be considered a group at the division level (comparable to the phylum level in animal classification systems) called Anthophyta, though the APG system recognizes only informal groups above the level of order. Angiosperms or In ferns, the sporophyte is dominant; the gametophyte is tiny and short-lived. As plants evolved, moving from the sea to land, there were many adaptations that needed to occur to sustain the new mode of life. The next step that allowed for the evolution of trees was the evolution of the seed. Plants do the oppositethey breathe in CO2 and breathe out oxygen during photosynthesis.
