Question: What is a characteristic shared by algae and seed plants? Answer: chloroplasts Both algae and seed plants have cells with chloroplasts. Question: The closest algal relatives of land plants are _____. Answer: charophytes These green algae and plants share many homologous features. Que

By developing a shoot and growing taller, individual plants captured more light. Because air offers substantially less support than water, land plants ...
The kingdom Plantae constitutes large and varied groups of organisms. There are more than 300,000 species of catalogued plants. Of these, more than 260,000 are seed plants. Mosses, ferns, conifers, and flowering plants are all members of the plant kingdom. Land plants arose within the Archaeplastida, which includes the red algae (Rhodophyta) and two groups of green algae, Chlorophyta and Charaphyta. Most biologists also consider at least some green algae to be plants, although others exclude all algae from the plant kingdom. The reason for this disagreement stems from the fact that only green algae, the Chlorophytes and Charophytes, share common characteristics with land plants (such as using chlorophyll a and b plus carotene in the same proportion as plants). These characteristics are absent from other types of algae.

The first plants to colonize land were most likely related to the ancestors of modern day mosses (bryophytes), which are thought to have appeared about 500 million years ago. They were followed by liverworts (also bryophytes) and primitive vascular plants—the pterophytes—from which modern ferns are descended. The life cycle of bryophytes and pterophytes is characterized by the alternation of generations, which is also exhibited in the gymnosperms and angiosperms. However, what sets bryophytes and pterophytes apart from gymnosperms and angiosperms is their reproductive requirement for water. The completion of the bryophyte and pterophyte life cycle requires water because the male gametophyte releases flagellated sperm, which must swim to reach and fertilize the female gamete or egg. After fertilization, the zygote undergoes cellular division and grows into a diploid sporophyte, which in turn will form sporangia or “spore vessels.” In the sporangia, mother cells undergo meiosis and produce the haploid spores. Release of spores in a suitable environment will lead to germination and a new generation of gametophytes.

All plants alternate generations. There is an evolutionary trend from sporophytes that are nutritionally dependent on autotrophic (self-feeding) gametophytes ...
The plant life cycle alternates between haploid and diploid generations. Embryonic development is seen only in the diploid generation. The embryo, however, is produced by the fusion of gametes, which are formed only by the haploid generation. So understanding the relationship between the two generations is important in the study of plant development.

These adaptations allowed seedless vascular plants to outcompete nonvascular plants in early colonization of life on land. True roots grow deeper into the soil ...
We have already spent quite a bit of time considering the evolutionary tree of life and the three domains of life, but we have focused mostly on domain-level evolutionary innovations that occurred in the Archaean and Proterozoic Eons. Now we will move into the Phanerozoic Eon (the current eon) and narrow in on one specific lineage of multicellular eukaryotes within the domain Eukarya: land plants.
