1. CHAPTER 1 Plants Grow and Change

2. LESSON 1
WHAT ARE LIVING AND NONLIVING THINGS?

3. The world is made up of living and nonliving things.

4. FOOD WATER AIR LIVING THINGS…. All living things grow and change.
All living things need 3 things to grow.
WATER
FOOD
AIR

5. NONLIVING THINGS…. Nonliving things are not alive.
Nonliving things DO NOT grow.
Nonliving things DO NOT change.
Nonliving things DO NOT
need food, water, and air.

6. Living things come from
other living things.
__________________________________________________

7. Living things need nonliving things.
Plants need air, water, and light to grow.
People and animals need air, food,
and water to remain living.
Air, water, light and food are not alive……
so they are nonliving things.
Without nonliving things, living things could not survive. They would DIE.

8. THINK ABOUT IT How are all living things alike?
All living things need food, air, and water.
Living things also grow and change.
How do living things use nonliving things?
Plants use air, water, and light to grow.
People and animals use air, water, and food to live.

9. LESSON 2
HOW DO PLANTS CHANGE AND GROW?

10. Plants need light, air, and water to change and grow.
Plants also need nutrients.
Nutrients are minerals found in the soil.
Each part of the plant helps the
plant get what it needs to grow
and change.

11. PARTS OF A PLANT
FLOWER
SEEDS
____________
LEAVES
STEM
ROOTS

12. JOBS OF THE PLANT PARTS seeds flower leaves stem roots
---- a baby plant
flower
----makes seeds
leaves
---- use light, air, and nutrients
to make food
stem
---- holds up plant; moves water
and nutrients through the plant
roots
---- hold plant in soil; take in water
and nutrients from the soil

13. PARTS OF A SEED Seeds have different parts. Each
part helps the seed grow a new plant.
TINY PLANT
----uses stored food
to grow
STORED FOOD
SEED COAT
----protects the seed

14. HOW PLANTS GROW FROM SEEDS
A seed will begin to germinate, or grow, when it
gets water and warmth.
2. First, the roots grow down.
3.Then, a stem grows up.
(**This young plant is called a seedling.**)
4. The seedling continues to grow and change.
It makes more leaves and stems. It gets
taller and thicker.
When fully grown, its flowers make fruits that hold seeds.

15. THINK ABOUT IT What happens when a seed germinates?
When a seed germinates, it begins to grow.
The roots begin to grow down and the stem
grows up.
What are some ways plants may change?
Plants change as they grow. They get larger, grow more stems and leaves, get thicker, and produce flowers or fruits that make seeds.

16. LESSON 3
HOW ARE PLANTS ALIKE AND DIFFERENT?

17. Plants live in almost every part of the world.
Different kinds of plants grow in different
places.
Oak Forest
Desert
Pine Forest

18. A pine tree has leaves that
look like needles.
Its seeds grow in cones.

19. An oak tree has leaves that are broad and flat.
Oak trees grow from seeds inside acorns.

20. A cactus grows in a desert. It stores water in its thick stems.
Its leaves are sharp spines. The spines protect the cactus
from animals that might eat it.
Cactuses flowers grow into fruit.
The seeds of the cactus are inside the fruit.

21. THINK ABOUT IT What are some places plants live?
Some of the places plants live are pine
forests, oak forests, and deserts.
How are plants in different places alike
and different?
All plants are living things. They all need air, water, light, and nutrients. Plants that grow in different places may look different, and have different kinds of stems, leaves, and seeds to help them live and grow.
