Biology

Answer:

Prokaryotes are smaller and less developed compared to eukaryotes. Some of them inhabit very primitive environments that resemble earth’s early stages. Endosymbiotic theory states that eukaryotes arose by the endosymbiosis of prokaryotes.

Explanation

By endosymbiont theory, eukaryotic cells arise from prokaryotic cells. Here, the theory shows that eukaryotic ancestors lived in close association with prokaryotes, wherein in some cases, prokaryotes have been engulfed and might have lived inside eukaryotes.

Upon being engulfed by a host cell as undigested prey, these prokaryotes could have been internal parasites of the eukaryotes. But, later on, their relationship becomes mutualistic and these prokaryotes become incorporated as organelles, such as in the case of chloroplasts and mitochondria, which were previously separate prokaryotes

Romashka-Z-Leto [24]

Answer:

C. their gametes do not require water for fertilization to occur.

Explanation:

Seed bearing plants are plants that produce seeds. The gametes of seed-bearing plants do no depend on water for fertilization. Fertilization could occur through the transfer of pollen from the male gametophtye to the female gametophyte through animals or wind.

Unlike other plant types like the bryophytes, they rely on water for fertilization. They so have xylem and phloem as well as other plants. They also have stems,roots and leaves like other plants.
