Investigating Plant Structure and Function: Plant Tissues

The video explains plant growth starting from seed germination, focusing on the role of mitosis in meristematic tissues. It describes apical and lateral meristems, highlighting their functions in plant growth. The video also covers dermal tissue, emphasizing its protective role and the presence of cutin on leaves. Ground tissues are introduced, followed by a detailed explanation of vascular tissues, xylem, and phloem, and their roles in transporting water, minerals, and nutrients.

What is the primary function of apical meristems in plants?

• To transport water and nutrients

• To protect the plant from external damage

• To store food and nutrients

• To add cells to the tips of roots and stems

Which type of tissue forms the outer protective layer of leaves?

• Vascular tissue

• Dermal tissue

• Ground tissue

• Meristematic tissue

What is the main role of cutin on leaves?

• To prevent water loss

• To transport nutrients

• To support the plant structure

• To aid in photosynthesis

What is the primary function of xylem in plants?

• To transport sugars

• To conduct water and minerals

• To store nutrients

• To protect the plant

How do sieve cells in phloem facilitate the transport of nutrients?

• By having thick cell walls

• By storing nutrients

• By being dead cells

• By containing holes for material passage
