The stem is an external plant part. The stem is strong and helps hold the plant up. It also lets water and nutrients flow up to the leaves. Some examples of stems we eat are celery, asparagus, and sugar cane. Leaves are an external plant part. Leaves collect sunlight and make food for the plant.
The children will learn the basic parts of plants (roots, stems, leaves, flowers, and seeds) and the function of each part. Objective Description • Learn that di˜erent parts of plants have di˜erent functions • Observe the similarities and di˜erences between plants • Understand the parts of the plant help it survive and grow
Overview of plant parts: Stem: structural support of the plant; stores nutrients; transfers fluids; produces new tissue.
Learning Objective. Identify the main external structures of the shoot system, including the nodes, internodes, leaves, axillary buds, and axillary shoots. Plant stems, whether above or below ground, are characterized by the presence of nodes and internodes (Figure 3.3.1.1 3.3.1. 1). Nodes are points of attachment for leaves.
The lesson objectives are for students to understand the external parts of plants and their functions, as well as the importance of plants to humans. The teacher presents the parts of a plant - flowers, stems, leaves, and roots - by singing a song with the class.
Students explore external plant parts through real life examples of roots, stems, leaves, flowers, fruits and seeds to understand how they work together to help plants survive. Duration: 20-40 minutes.
Stem: The stem is the stalk or trunk of a plant. Like the roots, stems also help the plant survive. They act like the plant's plumbing system, conducting water and nutrients from the roots and leaves to other plant parts. Stems can be herbaceous like the bendable stem of a daisy or woody like the trunk of an oak tree.
