Explanation:
Chromoplasts are very' similar to chloroplasts, but they do not contain the green pigment chlorophyll. Instead, they contain other pigments which give color to flowers and to leaves during the fall. Leucoplasts are non-pigmented colorless plastids.
Leucoplasts are colorless plastids and mainly help in storage of food compounds like starch, proteins or fats. Such, colorless plastids are present in underground roots, stems.
Leucoplasts are important organelles for the synthesis and storage of starch, lipids and proteins. However, molecular mechanism of protein import into leucoplasts and how it differs from that of import into chloroplasts remain unknown.

Chloroplasts are not found in root cells:-
Chloroplasts are small bodies, or organelles, found in green plant cells. They float in the cytoplasm and are not attached to the cell walls. Chloroplasts contain chlorophyll, a green pigment that can convert solar light energy into fuel. Plants convert carbon dioxide from the atmosphere and water from the soil into sugars.
When light strikes a chlorophyll molecule, it excites and causes it to give up an electron. As a result, the chlorophyll molecule steals an electron from water, making the water molecule unstable. This causes it to decompose and emit oxygen and hydrogen. The oxygen is released into the atmosphere, but the plant uses the hydrogen to produce simple sugars.
The roots' function is to absorb and store water and nutrients from the soil while supporting the plant. The roots of many plants are also used for reproduction, and some plants' roots can be cut up and replanted to grow new plants.
Leucoplasts:-
Leucoplasts are plastids that consist of many distinct colourless organelles that serve as a source of starch in non-green tissues such as roots, tubers, or seeds. Leucoplast's primary function is to store starch, lipids, and proteins.
Chloroplasts:-
All green plants and algae contain chloroplasts and are the plant food producers. These are found in mesophyll cells located in the leaves of plants, and they have a high concentration of chlorophyll, which absorbs sunlight, and animal cells do not have this cell organelle.
- Chromoplasts are colour plastids in all flowers and fruits, primarily responsible for their distinct colours.
- Chloroplasts are green-coloured plastids that contain green-coloured pigments called chlorophyll within the plant cell.
- Leucoplasts are colourless plastids primarily used to store starch, lipids, and proteins within the plant cell.
