What is a Stem?
The stem is the structural centre of the plant that carries water and nutrients to different parts of the plant. It also provides support and keeps the plant standing upright.

Slide 4 - Slide

This item has no instructions

Function 1: Support
Stems help support the weight of leaves, flowers, and fruits, keeping them in the light for growth and photosynthesis.

Slide 5 - Slide

This item has no instructions

Function 2: Transport
Stems transport water, nutrients, and fluids between the roots and the upper parts of the plant through the xylem and phloem.

Slide 6 - Slide

This item has no instructions

Function 3: Storage of Nutrients
Stems have tissue called the meristem, which contains dividing cells. These cells produce new living tissue and help distribute vital nutrients throughout the plant.

Slide 7 - Slide

This item has no instructions

Identifying Stem Parts
The main parts of a stem are the nodes, internodes, buds, and vascular bundles. These parts play important roles in plant propagation in horticulture.

Slide 8 - Slide

This item has no instructions

Node and Internode
The node is the point on a stem where leaves, buds, and branches originate. The internode is the segment between two nodes.

Slide 9 - Slide

This item has no instructions

Buds and Vascular Bundles
Buds are undeveloped shoots that can grow into new branches or flowers. Vascular bundles are groups of xylem and phloem tissues responsible for transport.

Write down 3 things you learned in this lesson.

Slide 16 - Open question

Have students enter three things they learned in this lesson. With this they can indicate their own learning efficiency of this lesson.
Write down 2 things you want to know more about.

Slide 17 - Open question

Here, students enter two things they would like to know more about. This not only increases involvement, but also gives them more ownership.
