After the plants grew up‚ we measured the leaf density of both treatments. We then randomly selected 10 parents in control treatment‚ and also selected 10 parents with lowest leaf density in the experiment treatment to establish the offspring generation. When the offspring population had the same growing time as the original population‚ we measured the leaf density of the two offspring populations and compare to the two original populations. We found that the leaf density of the plants was a variable

The sudden appearance and domination of angiosperms/flowering plants. This can be defined as an explosion because plants went from relative unimportance to suddenly taking a revolutionary role in the entire earth’s ecosystem. Just like an explosion‚ angiosperms spread extremely suddenly and rapidly. 3. What type of plants were the first to appear

With the application of the electricity through Antenna system‚ the growth of clover has increased to 7 feet high.
