The Seed and Plant Kingdom-Parts of a Plant and Their Functions

Learning Objectives

• Describe the process of germination and the development of a seed into a new plant.
• Identify and explain the functions of the different parts of a seed and a flowering plant.
• Recognize and categorize seeds based on shape, color, and size.
• Understand the life processes of plants, including breathing, feeding, growing, reproducing, giving off waste, and moving.
• Differentiate between monocotyledons and dicotyledons based on the number of cotyledons.
• Match plant structures like the radicle, plumule, and cotyledon to their corresponding functions.

The Germination Process

Seeds begin the germination process to develop into new plants.

Seed Anatomy

• Cotyledon
• Plumule
• Radicle
• Hilum
• Micropyle
• Testa/Seed Coat

Seed Diversity

Seeds can be classified as monocotyledons or dicotyledons based on the number of cotyledons.

Life Processes of Plants

• Breathing
• Feeding through photosynthesis
• Growing
• Reproducing
• Expelling waste
• Moving

Monocotyledons and Dicotyledons

Understanding the difference based on the number of cotyledons.

Plant Structures and Functions

• Roots, stems, leaves, fruits, and flowers, each with distinct functions.

Definitions

Germination: The process where a seed grows into a new plant.
Cotyledon: A fleshy part of the seed that provides food for the young plant.
Plumule: The part of a seed embryo that develops into the shoot.
Radicle: The part of a seed embryo that grows into the root.
Hilum: The scar on a seed marking where it was attached to the plant.
Micropyle: A small opening in the seed coat that allows water and air to enter.
Testa/Seed Coat: The protective outer covering of a seed.
Monocotyledon: A seed with one cotyledon.
Dicotyledon: A seed with two cotyledons.
Photosynthesis: The process by which plants make their own food using sunlight.
Invertebrate: An animal without a backbone.

What are the functions of the different parts of a seed?

1. Store food for the embryo, protect the embryo
2. Absorb water and nutrients, produce seeds

How can seeds be categorized?

1. By shape, color, and size
2. By taste, smell, and texture

What is the difference between monocotyledons and dicotyledons?

1. Monocots have one cotyledon, dicots have two
2. Monocots have two cotyledons, dicots have one

Write down 3 things you learned in this lesson.

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.

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

Ask 1 question about something you haven't quite understood yet.

The students indicate here (in question form) with which part of the material they still have difficulty. For the teacher, this not only provides insight into the extent to which the students understand/master the material, but also a good starting point for the next lesson.
