Question

Define plastids. What are the different types of plastids define each of them.

Answer 1

Answer:

Plastids are double-membrane organelle which are found in the cells of plants and algae. Plastids are responsible for manufacturing and storing of food. These often contain pigments that are used in photosynthesis and different types of pigments that can change the colour of the cell.

types

Three types of plastids are chloroplasts, leucoplasts and chromoplasts.

choloroplast.

Plants use energy from the sun in tiny energy factories called chloroplasts.

leucoplast.

Leucoplasts are colorless plastids

found in endosperm, tubers, roots and other non-photosynthetic tissues of plants. They serve various functions, for example, storage of starch, lipids, or proteins.

chromoplast

A chromoplast is a pigmented plastid found in certain plant cells. Chromoplasts that contain carotenoid pigments impart the red, orange, or yellow colors to various fruit (e.g., tomato fruits), roots (e.g., carrot roots), and petals

Answer 2

Plastids are present only in plant cells. These are special organelles that manufacture and store pigments. They are bound by a double membrane. Plastids are of three types.

• Chloroplasts - These are plastids that contain green pigment called chlorophyll. They impact green colour to leaves and other plant parts where they are present. A chloroplast shows two regions - grana and stroma.
• Chromoplasts - These are plastids with coloured pigments other than green. They are mostly found in fruits and petals of flowers. The red, orange or yellow colour of fruits and flower is due to the presence of chromoplasts.
• Leucoplast - These are colourless plastids devoid of any pigment . They store food prepared in the plant, in the form of starch , proteins and fats. They are found in the roots of plants and in underground stems such as potato and ginger.
