Taxonomy is the branch of science concerned with the classification, identification, and naming of organisms. It involves arranging organisms into hierarchical categories based on their shared characteristics and evolutionary relationships. The study of tissues is Histology, and the study of fossils is Paleontology.
Explanation:
Reverse transcription synthesizes DNA from an RNA template, catalyzed by reverse transcriptase in retroviruses and used in molecular biology for cDNA synthesis.
Explanation:
The root cap is a thimble-like mass of parenchyma cells covering the apical meristem, protecting it as the root pushes through the soil. It also secretes mucilage to ease passage. Cells are constantly sloughed off and replaced. The meristematic zone is where cells divide.
Explanation:
Self-pollination (autogamy) occurs within the same flower or between flowers of the same plant. Cross-pollination (allogamy) involves different plants. Hydrophily is pollination by water, anemophily by wind. Self-pollination ensures genetic uniformity, while cross-pollination promotes variation. Cleistogamous flowers (e.g., groundnut) are obligate self-pollinators.
