Is there a species-specific or region-specific type of plastid? How does one distinguish one from the other?

(A) $\therefore$ Plastids are found in all plant cells and in euglenoids.
$\Rightarrow$ These are easily observed under the microscope as they are large.
$\Rightarrow$ They contain specific pigments,thus imparting specific colours to the plants.
$\Rightarrow$ Based on the type of pigments,plastids are classified into three types: $(a)$ Chloroplasts,$(b)$ Chromoplasts,and $(c)$ Leucoplasts.
$(a)$ Chloroplasts: These contain chlorophyll and carotenoid pigments,which are responsible for trapping light energy essential for photosynthesis.
$(b)$ Chromoplasts: These contain fat-soluble carotenoid pigments like carotene,xanthophylls,and others. This gives the plant parts a yellow,orange,or red colour.
$(c)$ Leucoplasts: These are colourless plastids of varied shapes and sizes that store nutrients.
$(i)$ Amyloplasts: Store carbohydrates,e.g.,potato.
$(ii)$ Elaioplasts: Store oils and fats.
$(iii)$ Aleuroplasts: Store proteins.
