PLANTS – NOTES

Plants are living things.
• They need air, food and water in order to survive.
• Unlike animals, plants can make their own food.

Different Parts of a Flowering Plant

Flower

Leaf

Stem

Root

3D Model – Flowering Plant

Parts of flowering plants and their functions

• Roots enable the plant to absorb water and minerals from the soil.

• Many plants have underground roots found in the soil, but roots can also
be found above the ground.

• Stem helps to transport food, nutrients and water.
• Most plants have stems that are found above ground, but some have

stems that grow underground.

• Leaves produce food for the plant.
• They come in different shapes and sizes and contain leaf veins.

• Flowers enable the plant to produce fruits.
• They come in different sizes and colours, only plants with flowers produce

fruits, but not all plants have flowers.

PLANTS – NOTES
Plants can be classified into flowering and non-flowering plants.
• Flowering plants bear flowers that grow into fruits, which contain seeds.

• Some examples include the banana tree, hibiscus, and rose.

• Non-flowering plants do not bear flowers or fruits. Some reproduce via
spores.

• Some examples include moss, algae and ferns.

Activity 1 – Recalling Concepts
Fill in the blanks below.

1. Plants can be divided into two groups: plants
•F plants
•N

2. Plants have the following parts:

• R which are found underground.

•S which are often found above ground.
•L which come in many different sizes,

shapes and colours.

3. Adult flowering plants produce: which can be eaten by animals
•F
•F

4. N plants do not bear fruits.

5. Some non-flowering plants reproduce via s .
.
6. Plants are able to produce their own f

DISCUSSION QUESTIONS
We are going to look at a very ancient plant that lives on our shores.
As you watch the video, think about the following:
1. Why are seagrasses important?
2. Are they flowering or non-flowering plants?
3. What are some things that threaten seagrass?
4. What are some things we can do to preserve them?
