The video tutorial explains the concept of stem cells, highlighting their ability to divide and differentiate into specialized cells. It covers three main types: embryonic stem cells, which can become any cell type; adult stem cells, which are more limited in differentiation; and plant stem cells, which persist throughout a plant's life. The tutorial emphasizes the importance of stem cells in growth, development, and repair in both animals and plants.

What is one of the key abilities of stem cells?

• They can only form nerve cells.

• They cannot divide at all.

• They can differentiate into specialized cells.

• They can only divide by meiosis.

What is the unique feature of embryonic stem cells?

• They cannot divide by mitosis.

• They can only become skin cells.

• They can differentiate into any cell type.

• They are found only in plants.

Where are adult stem cells typically found?

• In the liver.

• In the brain.

• In the bone marrow.

• In the heart.

What is the role of plant stem cells in meristem tissues?

• They only form root hair cells.

• They help in photosynthesis.

• They differentiate into various plant cell types.

• They transport water and minerals.

How do plant stem cells differ from embryonic stem cells?

• They persist throughout the plant's life.

• They disappear after the plant is fully grown.

• They can only form leaf cells.

• They are found in animal tissues.
