FAQs on Plastids Video Lecture - Class 8

1. What are plastids and what is their role in plant cells?

Ans. Plastids are specialized membrane-bound organelles found in plant cells. They have various functions, such as storing and synthesizing important compounds, assisting in photosynthesis, and providing pigmentation to plant tissues.

2. Are all plastids involved in photosynthesis?

Ans. No, not all plastids are involved in photosynthesis. Chloroplasts, a type of plastid, are primarily responsible for photosynthesis. Other plastids, such as chromoplasts and leucoplasts, have different roles, like storing pigments or storing starch, respectively.

3. Can plastids be found in animal cells?

Ans. No, plastids are exclusive to plant cells and are not found in animal cells. Animal cells do not possess the ability to carry out photosynthesis, which is the primary function of plastids.

4. Can plastids change their type or function?

Ans. Yes, plastids have the ability to change their type and function. For example, when a leaf changes color in the autumn season, chloroplasts can transform into chromoplasts, leading to the production of different pigments and giving the leaf its vibrant hues.

5. How are plastids inherited in plants?

Ans. Plastids are typically inherited from the mother plant. During plant reproduction, plastids are passed on through the cytoplasm of the ovule, which contains the female gamete. This means that the plastids in a plant are usually derived from the plastids of its maternal parent.
