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
Comparing plant and animal cells
