Plant Structure and Function Concepts

The video tutorial explains the structure and function of a typical angiospermic plant. It covers the shoot system, including the stem, nodes, and internodes. The leaf's structure, its parts, and functions like photosynthesis and transpiration are detailed. The video also describes venation patterns in dicots and monocots. Finally, it discusses the flower as a reproductive organ, highlighting its development from buds and its role as a modified stem.

Where do leaves develop on the stem?

• Internodes

• Axils

• Nodes

What is the role of axillary buds in plants?

• They store nutrients

• They absorb water

• They produce branches

• They produce flowers

What is the function of terminal buds?

• To produce flowers

• To maintain vertical growth

• To absorb sunlight

• To store food

Which part of the leaf is responsible for photosynthesis and transpiration?

How do some scientists describe a flower in relation to the stem?

• As a modified root

• As a modified stem

• As a leaf structure

• As a separate organ
