Types of Plant Tissues

The video explains how plant cells organize into tissues and organs. It covers the three main types of plant tissues: ground, dermal, and vascular. Ground tissue includes parenchyma, collenchyma, and sclerenchyma, each with specific functions. Dermal tissue, like the epidermis, protects the plant, while vascular tissue, including xylem and phloem, is crucial for nutrient transport. The video highlights the importance of these tissues in plant structure and function.

What is the primary role of cells in living organisms?

• To act as a protective layer

• To perform photosynthesis

• To serve as the building blocks of life

• To transport nutrients

Which type of ground tissue is most common in plants and is responsible for photosynthesis?

• Sclerenchyma

• Parenchyma

What is the function of the cuticle in dermal tissue?

• To transport water

• To aid in photosynthesis

• To store nutrients

• To prevent water loss and protect against pathogens

What are stomata primarily responsible for in plants?

• Photosynthesis

• Gas exchange

• Nutrient storage

• Structural support

Which type of vascular tissue is responsible for transporting water and minerals upwards in a plant?

• Epidermis
