What are living things?

Living things grow, respond to the world around them, and reproduce.

What do living things need?

Living things need food, water, and space.

Many also need gases found in air or water.

What are living things made of?

Living things are made up of cells.

How can you tell the difference between a living and a nonliving thing?

Main Idea

Living things have needs, grow, respond, and reproduce. Living things are made up of cells.

Nonliving things do not have needs and do not grow, reproduce, or respond.

Living things ___________ , or react, to the world around them.

What are plants?

Most plants have roots, stems, and leaves.

They use energy from the sun to make their own food.

How do roots and stems help plants?

These are structureswhich hold the plant in place and help it take in nutrients.

Why are leaves important? Leaves take in the carbon dioxide and sunlight that plants need for photosynthesis.

Leaves also give off oxygen and make food for the plant.

How can you classify plants?You can classify plants by their structures (roots, stems, leaves) or by whether they are flowering or non-flowering.

What three structures do most plants have?

Main Idea

Roots, stems, leaves

Plants make food through a process called ______________.

______________ are substances that helpliving things grow and stay healthy.

Many plants have the same basic______________, or parts.

Roots

Parts of a Plant

Stems hold a plant upright so its leaves can get sunlight and they transport materials throughout the plant.

Roots take in water and nutrients and keep a plant in place.Summarize

How do a plant’s parts

help it survive?

Leaves take in carbon dioxide and energy from sunlight. Leaves are where photosynthesis takes place.

What are animals?

Animals are living things that can usually move and respond to their environment in a variety of ways.

They get their energy and nutrients by eating other organisms.

How do animals get what they need?

Animals have structures that help them get what they need for survival.

How do animals stay safe?

Some animals have structures to help them stay safe and the others find shelter.

How are animals alike?

Main Idea

All animals move, respond to their environment in noticeable ways, eat other organisms for energy, and have structures that help them meet their needs.

___________ are structures that take in oxygen from the water.

Some animals stay safe by finding a safe place, or ___________.

___________ are structures that take in oxygen from the air.
