The answer for the question is the Apical meristem.
Growth in plants occurs as the stems and roots lengthen. Some plants, especially those that are woody, also increase in thickness during their life span. The increase in length of the shoot and the root is referred to as primary growth. It is the result of cell division in the shoot apical meristem.
This is false. The more similarities the the amino acid sequences have, the closer related are the species. Therefore the more differences in the sequence, the more further related the two species are.
Answer:
Genetic evidence like difference in ribosomal sequence.
Explanation:
Earlier archaea were considered in bacteria because of their similar appearance with bacteria. Other than similar appearance they also show other similarities with bacteria like lack of nucleus and membrane-bound organelle, presence of single chromosome, mode of reproduction, etc.
Carl Woese was the scientist who discovered archaea and made a separate domain for archaea. After the sequencing archaeal genome, he found that the gene sequence like rRNA sequence of archaea is not similar to bacteria and eukarya. So by genetic evidence, he divided prokaryotes into two domain bacteria and archaea.
