The authors of this 2012 review article summarize the problem well in their introduction: In contrast to the tremendous advances in throughput, assembling sequencing reads remains a substantial endeavor, much greater than the sequencing efforts alone would suggest [22-24]. Large complex plant genomes remain a particularly difficult challenge for de novo ...

I looked in Taiz and Zeiger. Plant Physiology 5th ed and this is what I found: Plant growth is concentrated in localized regions of cell division called meristems. Nearly all nuclear divisions (mitosis) and cell divisions (cytokinesis) occur in these meristematic regions. In a young plant, the most active meristems are called apical meristems; they ...

A bud is capable of developing into a new individual while meristem can develop into any part of the individual. Buds can produce shoots, flowers, etc. while meristems have more variability - capable of developing into the tissues within the stem, a new individual, etc.

The most obvious answer to your question is that the enzyme responsible for nitrogen fixation is inactivated by oxygen. So photosynthesis, which produces oxygen, rules out nitrogen fixation, and, as you know, plants photosynthesise. However, they could have evolved specialized cells for nitrogen fixation, which do not photosynthesise. In fact, some colonial ...

This book could be a good start: Botany by Mauseth. However if you don't have any knowledge about biology I suggest you to get starting with the basics of cellular biology. A good book could be "The cell" by Cooper, you can find it in electronic version. There are many books about cellular biology but I recommended this because it is complete and detailed ...
