LIFE SCIENCE

What is Life Science?

Everything in the world can be put into two categories: Living things

Ex: Animals. Bacteria, insects

Non-living things Ex: rocks, water, air

What is Life Science?

Life science is the study of living things Also known as Biology Scientists who study living things are

called biologists Some of the fields can be broken down

into specialized branches: Ex: Zoology (study of animals), botany (study

of plants)

How Biologists Work

Depending on the field, they may work in different ways, but they share one thing in common: many biologists work in a lab at least part of the time

What might a biologist who studies genetics do?

A microbiologist?

Living Things are Alike

What do all living things have in common?

Cells!

Organize your thoughts!

Create a flow chart with the following information: Living things have similarities and differences The similarities include they consist of cells,

have life activities, and use/require important chemicals

The differences include the 5 kingdoms

Living things are made of cells

All living things are made of cells A cell is the basic unit of life Most living things are made of many cells Cells are found in all parts of animal

In animals they may up blood, bones, skin, nerves, and muscle

In plants they make up roots, stems, leaves and flowers

Cells

Cells carry out many specialized functions: Skin cells: cover and protect Muscle cells: allow for movement Bone cells: support and protect Nerve cells: send and receive messages Blood cells: transport material and fight

disease

Increase your vocab!

Another word for living thing is organism An organism is a complete, individual

living thing It can carry out all basic life activities Bacteria are the simplest organism that

can carry out all basic life activities

Bacteria

Observing cells

Cells come in different sizes Most cells are so small they are invisible

to the unaided eye In this case, they can only be seen with a

microscope A microscope is an instrument used to

magnify small things

Looking at cells

When looking at cells under a microscope, more details can be seen Size, shape, colors, etc. Even parts of a cell can be seen

Organelles: stores material , produces energy

Tissues

Groups of cells that are alike and act together to do a certain job are called tissues

Ex: muscle tissue

Organs

A organ is a group of different tissues that work together

Organs are the main working parts of animals and plants

Organs have specific jobs Even plants have organs

The roots, leave and stems are organs
