Plant Structure and Function Concepts

This video tutorial covers the anatomy and function of plants, focusing on roots, shoots, and leaves. It explains the structure and roles of nodes, buds, and modified shoots, as well as the types and functions of roots. The video also delves into the functions of leaves, including photosynthesis and gas exchange, and discusses the interdependence of plant systems. The tutorial emphasizes note-taking strategies and encourages students to organize their notes creatively.

What are the three basic structures of a plant?

• Roots, flowers, and fruits

• Shoots, leaves, and flowers

• Roots, shoots, and leaves

• Roots, stems, and flowers

What is the function of root hairs?

• To increase surface area for absorption

• To transport water

• To store food

• To anchor the plant

Which part of the shoot is responsible for growth at the tips?

• Nodes

• Apical buds

• Internodes

• Axillary buds

What type of root system is typical of monocots?

• Aerial root

• Adventitious root

• Tap root

• Fibrous root

What is the primary function of leaves?

• Water storage

• Photosynthesis

• Mineral absorption

• Gas exchange

What is the role of stomates in leaves?

• To facilitate gas exchange

• To protect the leaf

• To store water

• To transport nutrients

What is the difference between simple and compound leaves?

• Simple leaves have one leaf blade, compound leaves have multiple leaflets

• Simple leaves are always green, compound leaves change color

• Simple leaves are larger, compound leaves are smaller

• Simple leaves are found in monocots, compound leaves in dicots

How do roots and shoots depend on each other?

• Roots provide water and nutrients, shoots provide sugars

• Shoots provide water, roots provide sugars

• Shoots provide minerals, roots provide carbon dioxide

• Roots and shoots do not depend on each other

What is the function of xylem in the vascular system?

• Facilitate gas exchange

• Store nutrients

• Transport water and minerals

• Transport sugars

Which raw material is NOT obtained from the external environment for photosynthesis?

• Sunlight
