Plant Tissue Functions and Structures

The video tutorial covers the structure and growth of plants, focusing on the hierarchy of plant organization, including organs, tissues, and cells. It explains the roles of different plant parts in photosynthesis and growth, highlighting the importance of meristematic tissue in plant development. The tutorial also distinguishes between monocots and dicots, and describes the three major plant tissue types: dermal, vascular, and ground tissue. Additionally, it explores five categories of plant cells, emphasizing their functions in supporting plant structure and nutrient transport.

What is the primary function of the aerial parts of a plant?

• Absorbing water and minerals

• Utilizing light and carbon dioxide for photosynthesis

• Anchoring the plant to the ground

• Storing nutrients

Which type of tissue is responsible for plant growth?

• Dermal tissue

• Vascular tissue

• Meristematic tissue

• Ground tissue

What is the difference between primary and secondary growth in plants?

• Primary growth increases width, secondary growth increases height

• Primary growth increases height, secondary growth increases width

• Primary growth occurs in roots, secondary growth occurs in leaves

• Primary growth occurs in leaves, secondary growth occurs in roots

Which of the following is NOT an organ of a plant?

• Flower

• Root

• Stem

• Leaf

How do monocots and dicots differ in their structural organization?

• Monocots have ringed vascular bundles, dicots have scattered vascular bundles

• Monocots have scattered vascular bundles, dicots have ringed vascular bundles

• Monocots have fibrous roots, dicots have taproots

• Monocots have two seed leaves, dicots have one

What is the primary role of dermal tissue in plants?

• Transporting water and nutrients

• Storing food and nutrients

• Covering and protecting the plant

• Providing structural support

Which tissue type is responsible for transporting nutrients throughout the plant?

• Ground tissue

• Dermal tissue

• Vascular tissue

• Meristematic tissue

Which type of plant cell is known for its thick secondary cell walls and lignin content?

• Xylem cells

• Parenchyma cells

• Collenchyma cells

• Sclerenchyma cells

What is the main function of xylem vessels in plants?

• Providing structural support

• Transporting water and minerals

• Transporting sugars and organic nutrients

• Protecting against water loss

Which cells are responsible for transporting sugars in plants?

• Parenchyma cells

• Phloem cells

• Xylem cells

• Sclerenchyma cells
