The document provides an overview of a natural science unit on plants. It will cover how plants reproduce through flowers that have male and female organs and how seeds are formed through pollination. Students will learn to label the parts of plants and flowers. They will also learn what plants need to grow - water, light, and nutrients. The document further discusses the classification of flowering vs. non-flowering plants, plant nutrition through photosynthesis, and modes of sexual and asexual reproduction in plants. Activities include labeling parts of a plant and completing worksheets.

1. NATURAL SCIENCE
UNIT 1: THE PLANTS

3. •We will learn that plants produce
flowers which have male and female
organs.
•We will learn that seeds are formed
when pollen from the male organ
fertilises the female organ.
•We will learn to label the parts of a
plant and flower.

6. The roots
absorb water
from the soil.

7. The stem
helps to
support the
plant.

8. The leaves use
sunlight to make
photosynthesis.

9. The flower
helps the plant
to reproduce.

10. What do plants need to
grow ?

11. WATER

12. WATER
 Water is necessary for
proper germination of seeds.
 Plants need water for
growth.

13. LIGHT

14. LIGHT
 Green plants need sunlight in
to make their own food.

15. NUTRIENTS

16. NUTRIENTS
 Plants need the minerals
found in soil for healthy
growth.

20. CLASSIFICATION OF PLANTS.
 Flowering plants: These plants have organs like flowers, fruits and seeds that
help them to reproduce.
 ANGIOSPERMS: Have seeds and fruits.
 GYMNOSPERMS: Have seeds but not fruits.

21. CLASSIFICATION OF PLANTS.
 Non-flowering plants: These plants do not have sedes. They reproduce
through spores.
 Ferns: Have roots, leaves and stems.
 Mosses: Do not have roots, leaves and stems.
