-2 Motile cells are present in
a Animals
b flowering
c Contifurs
d All the obove​

Answer 1

Concept: Cell Biology

Answer: D, All the above

Explanation:

• Most of the animal cells are motile, Such as walking, sithering, swimming, and flying to propel themselves through the world. Many single-celled and microscopic organisms are also motile.
• Only male gametes (spermatozoids) are motile cells which reduced to non-flagellated celled in flowering plants.

• Conifer is a Latin word for "Cone bearing" because conifers produce within which they produce (male cone) and grow seeds it is also motile.

Answer 2

Motile cells are present in (d) All  the above

Explanation:

1.Neutrophils are very motile cells that respond to chemotactic stimuli. Their main functions are phagocytosis, killing and digestion of bacteria and other microorganisms.

2.They possess some 200 cytoplasmic granules of about 0.2 mm in diameter which contain a wide variety of oxidative metabolites and digestive enzymes.

3.cells use a number of diverse mechanisms to swim through liquid or crawl across solid surfaces.

4.The two most prevalent forms of eukaryotic cell motility are flagellar-dependent swimming and actin-dependent cell migration, both of which are used by animal cells and unicellular eukaryotes alike.

5.Most animals are motile, using means such as walking, slithering, swimming, and flying to propel themselves through the world.
