Diversity in Living Organisms

The microtubular arrangement in the flagellar filament is 9+2

Yes, it is the correct.

Paramecium is surrounded by numerous minute cilia on the body which help in movement.

Hydra somersaults like an acrobat with the help of tentacles.

Leech and earthworm perform crawling or looping movement with the help of contraction and relaxation of circular and longitudinal muscles.

Euglena moves with the help of flagella, i.e. it shows flagellar movement.

Starfish have tube feet as the locomotory organ.

Cilia are short, fine, vibratile hair-like processes present on the free surface of cells. They create a current in water by means of their oar-like activity and help in movement of cells.

It is a heterotypic bone formed in the eyelids of crocodile.

Photosynthesis is a process that converts carbon dioxide into organic compounds, especially sugars, using the energy from sunlight. Photosynthesis occurs in plants, algae, and sulphur bacteria, but not in archaea. Photosynthetic organisms are called autotrophs, since they can create their own food.

Bacteria and blue-green algae belong to the group 'prokaryotes'.

Mosquitoes are attracted to warm-blooded animals because they rely on heat and chemical cues like carbon dioxide to locate their hosts. Humans and other mammals are their primary targets.

Algae live as epibionts on many larger marine animals.

Reptiles do not lay eggs in water.

While it was long debated, studies have shown that giraffes are physically capable of swimming, though they are not natural swimmers and avoid water when possible. However, in the context of general knowledge quizzes, 'No' is often the expected answer due to their anatomy.
