Meristematic Cells and Plant Growth

The video tutorial explains meristematic tissue in plants, focusing on its role in growth. It describes the two main types: apical meristems, which contribute to lengthwise growth, and lateral meristems, which enable widthwise growth. The video also details the characteristics of meristematic cells, such as their ability to divide constantly, and highlights their structural features like a large nucleus and thin cell walls.

Where are meristematic tissues primarily found in plants?

• In the bark and wood

• In the fruits and seeds

• In the tips of stems and roots

• In the leaves and flowers

What is the main function of apical meristems?

• To enable the plant to grow in width

• To enable the plant to grow in length

• To produce flowers

• To store nutrients

Which type of meristematic tissue allows a plant to grow thicker?

• Lateral meristem

• Apical meristem

• Basal meristem

• Intercalary meristem

What is a key characteristic of cells in the meristematic tissue?

• They have thick cell walls

• They have large vacuoles

• They have the ability to divide constantly

• They are dead cells

What is the role of cytoplasm in meristematic cells?

• To store water

• To provide energy for cell division

• To support the cell structure

• To transport nutrients

How do meristematic cells contribute to plant growth?

• By photosynthesis

• By storing food

• By absorbing nutrients from the soil

• By producing new cells through mitosis
