Question

Pick the odd one out and give the category of the other three:
(i) Centriole, Cell wall, Chloroplast, Plastid.
(ii) Scutellum, Testa, Coleoptile, Coleorhiza.
(iii) Humerus, Radius, Patella, Metacarpals.

Answer 1

Answer:

2nd option will be correct option of this ... Question

Answer 2

Answer:

While choosing this 1st as a correct option, cell wall, centriole and  chloroplast which is mostly prominent & one & only plant organelle, involves in larger family of plant organelles known as plastids, these collectively comes under the main organelles of plant cells

Explanation:

While choosing this as 1st option, every organelles have similarly comes under the plant cell category, having their different functions

Centriole - a unique plant organelle which aids to produce cilia during interphase and both aster & spindle during cell division and it's specifically found in some lower plant cells but absent in all higher plant cells

Cell wall - Outer protective layer of plant cell which aids structure, support, and protection for cell

Chloroplast - These are one and only but most prominent plant organelle, involves in larger family of plant organelles known as plastids and it is largely involved for photosynthesis and uniquely consists the internal thylakoid membrane system.

Plastid -  A family of plant organelles which consists the same genome as chloroplasts, but they differ in structure, aspect of plant cell metabolism and function, because these family are further divided into chromoplasts, leucoplasts, amyloplasts, elaioplasts and lastly chloroplasts. Thus, these are bounded by only two membranes of the plastid envelope but lacks both of the thylakoid membranes and other components of the photosynthetic apparatus.
