Which plastids are the Colourless?
The colourless plastids are called the leucoplast and their main function is the storage of food. Leucoplast is oval, spherical and rod in shape. It is found in fruits, seeds, tubers, and rhizomes of a plant and mainly stores food in the form of carbohydrates, lipids and proteins.
What are the Colourless plastids that store starch?
Leucoplasts (Fig. 1.9C) are a group of plastids that include many differentiated colorless organelles with very different functions (e.g., the amyloplasts), which act as a store for starch in non-green tissues such as roots, tubers, or seeds (Chapter 9).
Are chloroplasts Colourless?
Chlor, green, plast, and living) which contains chlorophyll a and b pigments, and DNA and RNA. The tomatoes and chillies when unripe are green but when become ripen turns red due to the conversion of chloroplasts into chromoplast. The leucoplasts are colourless plastids.
Why is Leucoplast Colourless?
Leucoplasts are colourless plastids of various shapes that generally occur in non green plant cells near the nucleus. As development of pigment requires light, when proplastids mature in darkness there is no pigment formation and colourless leucoplasts develop.

Are Leucoplasts white in Colour?
Leucoplasts are white or colourless plastids. They lack pigments and are found in the non-photosynthetic tissues of the plants. They may be specialised for bulk storage of proteins, lipid or starch.
Which of the following is NOT a colorless plastids?
Chloroplasts are the most important and common plastids found in all the photosynthesizing cells except prokaryotes. Leucoplasts are colour less plastids, found in the underground part of plants which are not exposed to light.

Leucoplasts are colourless plastids.
Which plastids provide Colour to fruits and flowers?
Chromoplasts
Explanation: Chromoplasts are coloured plastids found in roots, leaves, flowers and ripe fruits. They contain lipid-soluble pigments, referred to as carotenoids, that provide colour to many different types of plants and flowers.
