3The world is made up of living and nonliving things.
4FOOD WATER AIR LIVING THINGS…. All living things grow and change. All living things need 3 things to grow.WATERFOODAIR
5NONLIVING THINGS…. Nonliving things are not alive. Nonliving things DO NOT grow.Nonliving things DO NOT change.Nonliving things DO NOTneed food, water, and air.
6Living things come from other living things.__________________________________________________
7Living 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.
8THINK 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.
10Plants 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 theplant get what it needs to growand change.
11PARTS OF A PLANTFLOWERSEEDS____________LEAVESSTEMROOTS
12JOBS OF THE PLANT PARTS seeds flower leaves stem roots ---- a baby plantflower----makes seedsleaves---- use light, air, and nutrientsto make foodstem---- holds up plant; moves waterand nutrients through the plantroots---- hold plant in soil; take in waterand nutrients from the soil
13PARTS OF A SEED Seeds have different parts. Each part helps the seed grow a new plant.TINY PLANT----uses stored foodto growSTORED FOODSEED COAT----protects the seed
14HOW PLANTS GROW FROM SEEDS A seed will begin to germinate, or grow, when itgets 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 getstaller and thicker.When fully grown, its flowers make fruits that hold seeds.
15THINK ABOUT IT What happens when a seed germinates? When a seed germinates, it begins to grow.The roots begin to grow down and the stemgrows 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.
17Plants live in almost every part of the world. Different kinds of plants grow in differentplaces.Oak ForestDesertPine Forest
18A pine tree has leaves that look like needles.Its seeds grow in cones.
19An oak tree has leaves that are broad and flat. Oak trees grow from seeds inside acorns.
20A cactus grows in a desert. It stores water in its thick stems. Its leaves are sharp spines. The spines protect the cactusfrom animals that might eat it.Cactuses flowers grow into fruit.The seeds of the cactus are inside the fruit.
21THINK ABOUT IT What are some places plants live? Some of the places plants live are pineforests, oak forests, and deserts.How are plants in different places alikeand 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.
