Answer:
Sporophytes were branched before the evolution of vascular tissues
In early land plants the gametophytes were branched and complex like the sporophytes
Explanation:
The fossil record shows that early land plants appeared in the Ordovician Period, approximately 470 million years ago (Mya). These plants were non-vascular plants (e.g., mosses and liverworts) which can be recognized as fossilized spores. Thus, the first land plants could not transport nutrients like sugar, water, or minerals around the plant. Nowadays, it is believed that early land plants had gametophyte dominant life cycles (haploid life phase), while vascular tissues evolved as an adaptation to life on land, in the sporophyte (diploid life phase).
Answer:
Sorry, I dont remenber that process.
Sustainability refers to how a system remains biodiverse and productive over long periods of time. Succession is a series of predictable changes that occur in a community over time. After a fire, volcano, or other disaster, succession enables an ecosystem to recover.
In meiosis I, homologous chromosomes separate, while in meiosis II, sister chromatids separate. Meiosis II produces 4 haploid daughter cells, whereas meiosis I produces 2 diploid daughter cells. Genetic recombination (crossing over) only occurs in meiosis I. D
