Question

Which of these is wrongly matched?
A. Chloroplasts- chlorophyll
B. Elaioplasts- starch
C. Chromoplasts- carotenoids
D. Amyloplasts- carbohydrates
E. Aleuroplasts- protein

Answer 1

Hint: Plastids are organelles containing double membrane-bound pigment which is the site of the manufacturing and storage of chemical compounds. Plastids are derived from a bacterial cell and it's its own DNA, RNA, and ribosomes.

Complete answer
A. A chloroplast is a plastid that contains a green pigment called chlorophyll which helps in the process of photosynthesis. Chloroplasts are found in all photosynthetic tissues and organs. These organelles are lens-shaped contain green chlorophyll pigments associated with an internal thylakoid membrane system that mediates the light reactions of photosynthesis
B. Elaioplast is a different leucoplast which stores fat. Elaioplasts are the plastids which are specialized for the synthesis of lipids.
C. Chromoplast is colored plastids as it contains colored pigments (carotenoids, xanthophylls, etc).
D. Amyloplast is a comprehended leucoplast that stores starch which is carbohydrates. Amyloplasts are sites for the synthesis and bulk storage of starch and are found in roots and storage organs such as cotyledons, seed endosperm, and tubers. They may be involved in gravitropism in the root and shoot apices
E. Aleuroplast is a separated leucoplast that stores proteins.

Therefore, option B is incorrectly matched.

Note: Plastids are essential for a wide range of normal plant cell functions, and so have a number of specialist forms.Plastids are double membrane-bounded cytoplasmic organelles found in all plant cells and in euglenoids. They are easily observed under a light microscope. E. Haeckel (1866) introduced the term plasmid.
