Answer:
B. Chloroplasts have flagella and cilia and these structures are similar in shape and function to flagella and cilia found in bacteria.
Explanation:
The ENDOSYMBIOTIC THEORY is a theory that suggests the evolution of eukaryotic cells from prokaryotes. The theory explains that some organelles such as MITOCHONDRIA and CHLOROPLAST found in eukaryotic cells were once free-living prokaryotes. This theory was based on certain evidences that backed up the claim that chloroplasts were endosymbiont i.e a cell that lived in another cell. The evidences include:
- Chloroplasts have their own genome whose circular structure of DNA is identical to that of bacterial DNA.
- Chloroplasts replicate and divide through fission, the way bacteria divide
- Chloroplasts can be affected by antibiotics, a class of drugs that target bacteria.
However, among these evidences, the possession of flagella or cilia by chloroplasts is not included.
Answer:
Unique Biodiversity. Eighty percent of the world's known terrestrial plant and animal species can be found in forests, and tropical rainforests are home to more species than any other terrestrial habitat. A square kilometer of forest may be home to more than 1,000 species.

Stars are formed in clouds of dust and gas (nebulae.) Nuclear reactions at the center (core) of stars gives enough energy to make them shine brightly for many, many years. The exact l<span>ifetime of a star depends on its size.</span>
