Plastid

1. Lack of which plastids may affect the process of pollination?

Answer: 

Chromoplasts are responsible for synthesizing and storing pigments, giving plants their distinct color. They can be found in flowering plants, fruit roots, and aging leaves during senescence. These pigments, like carotenoids, attract pollinators to the plants.

2. List the structures that makes up a plastid.

Answer:  

Plastids are made of double membrane with its own DNA and ribosomes along with the pigments and the organic substances stored in it.

3. What are plastid used for?

Answer: 

Plastid is a plant cell organelle which perform various function according to the type of plastid. They are the storehouse of important chemical compound, site of photosynthesis, and also determine the color of cell.

4. Colored plastids present in carrots and sweet potatoes are?

Answer:

Chromoplasts– These are colored plastids. Their main function includes pigment synthesis and storage. They exist in flowering plants, fruit roots (carrots and sweet potato), aging leaves i.e. senescence, and are responsible for their color. Their distinctive color formation is due to carotenoids.

5. The places where plastids can be found in the living system are?

Answer:  

Plastids can be found only in plant cells and not in any other cells.

Plastids are cell organelles that are found in green plants and algae. Plastids are responsible for containing photosynthetic pigments, other coloring pigments, starch, proteins, fats, etc. substances. The credit for the discovery of plastid goes to Ernst Haeckel, however, the proper definition of plastid was given by Schimper.
