Lesson 1.1 The Study of Life
Key Concept:
Questions:
Biologists study life in all its forms
Notes:
Earth is home to an incredible diversity of life.
 Living things are found ________________________________
 Living things come in all __________________ and ______________
Ex: largest living thing is a ___________________ ______________
Smallest living things are made up of _______________ cell. They can only be
seen with a __________________________
________________________= is the part of Earth were all things live. Ex:
_________________________, ____________________,
__________________________, __________________________,
_________________________, and many more.
Biodiversity = the word diversity means a “variety”. What does the word bio
mean? ___________________
 There is more biodiversity closest to the equator. Give several reasons
this is so
1. _____________________________________________
2. _____________________________________________
Living things that can breed and reproduce are called __________________
Species make up the biodiversity we find here on Earth
 Scientists have identified about _____________________ species,
they believe there could be millions more that are unidentified
 Over half of all know species are ______________________
All Organisms share certain characteristics
________________________= is the scientific study of all forms of life, or all types
of organisms. An _________________________ is any individual living thing.
What do all organisms have in common? (Characteristics of life)
1.
_________________________ They are the basic unit of all living things or
the building block of life. Organisms can be made up of one cell
____________________ or many ______________________________.
Ex: Humans are __________________________ and bacteria are
____________________________
2. ___________________________________ All organisms need a source of
energy to survive. Plants get there energy from ______________________,
this is called ___________________________________. Most animals get
there energy by eating other organisms. That energy is used in metabolism.
____________________________= is all the chemical processes that happen
in an organism. These chemical processes break down molecules to help build
other molecules.
What would be an example of metabolism that occurs in humans?
____________________________________________________________
3. _____________________________________________ Organisms react to
many different things in their environment such as light, temperature, sound,
touch, and other parts the environment. These reactions help to keep the
organism alive. These things that organisms react to are called
________________. The organisms reaction is called a
__________________
Can you give an example of a stimulus response action a dog has?
____________________________________________________________
4. _____________________________________________________
Members of the same species must be able to reproduce in order to make more
of the same. These organisms will grow and develop in mature organisms that in
turn will be able to reproduce. Organisms can reproduce
____________________ or _____________________________
reproduction. When organisms reproduce they are passing on their
_______________________. Genetic material or DNA (deoxyribonucleic acid)
contains all the instructions the organisms needs to grow develop and reproduce.
