Answer:
16. D) All the above,17.B) Electron microscope
Explanation:
16. Plastids are a heterogeneous own circle of relatives of organelles determined ubiquitously in plant cells. Most distinguished are the chloroplasts which perform vital features inclusive of photosynthesis, the biosynthesis of fatty acids, in addition to amino acids. Like mitochondria, chloroplasts are derived from an endosymbiotic event. The plastid is a membrane-certain organelle determined withinside the cells of plants, algae, and a few different eukaryotic organisms. They are taken into consideration to be intracellular endosymbiotic cyanobacteria. Examples encompass chloroplasts, chromoplasts, and leucoplasts.
17.An electron microscope is a microscope that makes use of a beam of elevated electrons as a supply of illumination.
Electron microscopy (EM) is a way for acquiring excessive decision photographs of organic and non-organic specimens. It is utilized in biomedical studies to research the specified shape of tissues, cells, organelles and macromolecular complexes.
