Your creature
Background knowledge: The world is changing dramatically. In the next 100 years the
environment will be:
Note: In water and in space you will need to
consider gravity and how that changes your
creature of tomorrow. Think about different
pressure pressing upon your creature and
how this will change the look of your creature,
it’s bones and how its fluids move throughout
your creature.
Purpose: Demonstrate what you know about
the entire unit through the creation of a
creature.
1) You will capture the structure and function of all the unit areas in the graphic organizers provided.
This organized knowledge will provide support when creating your creature.
2) You will chose one of the three provided environments above and reflect carefully on everything
you have been taught. How can you create a creature to survive in the environment? What will they
need from the following unit topics to survive; adaptations, energy, photosynthesis, cellular
respiration, cells, cellular function/structure, organelles, organization of life (from atoms to organs to
systems to life), human body systems, and the interdependent relationship of every area in order to
be alive in your chosen environment? (You are the creator so you can mix and match anything within
the unit to make your superior being.)
3) Create your creature of tomorrow.
4) Write about your creature’s unique structures and functions and why it is able to survive in your
chosen environment.
5) Present your creature to a small group and possibly the entire class.

An element is something that contains only one type of atom. Carbon contains only carbon
atoms, Iron contains only iron atoms, and so on. These elements are important in that we all
need them to survive.

Photosythesis
Photosynthesis converts massive amount of Sunlight into electrical and then chemical energy.
The input is carbon dioxide (CO2), water (H2O), minerals and light, and the output is
carbohydrates (food) that we need for our nourishment, and oxygen that we need to breathe

What energy transformations occur in both the processes of photosynthesis and cellular
respiration
Objective
Students will be able to gather, analyze, and interpret data regarding the basic functions of
photosynthesis and cellular respiration
The purpose is to know photosynthesis and cellular respiration are important processes by
which energy is acquired and utilized by organisms
Light
https://www.youtube.com/watch?v=JUmT24R8CyA
Energy: Energy can be found in a number of different forms. It can be chemical energy, electrical
energy, heat (thermal energy), light (radiant energy), mechanical energy, and nuclear energy
In physical science, energy means the ability to do work. Work means a change in position,
speed, state, or form of matter. Therefore, energy is the capacity to change matter.
light is energy
Atoms and molecules (which are simply bound collections of
two or more atoms) can absorb light (= energy!).
Flashlight demo
Likewise, infrared light (= heat = energy!) wouldn't do any good
in heating up your home in the winter if it didn't get absorbed
by matter. Higher energy light photons, like X-rays, tend to
want to plow through more matter before they get absorbed.
(Hence, their use in medical imaging: they can pass through
your "soft" tissue, but are more readily absorbed in your
bones, which are denser.) How and why do photons get
absorbed by matter?
The process of photosynthesis involves two
stages of chemical reactions
Light-dependent Reactions
This is the first stage of the photosynthetic process. These reactions take place in the presence
of sunlight, and use light energy from the sun to produce ATP molecules and other molecules
known as NADPH. These molecules are used as the energy source to carry out the reactions in
the next stage of photosynthesis.
Light-independent Reactions (Calvin Cycle)
In this stage, energy-containing sugar molecules are synthesized. The ATP and NADPH produced
in stage I are used to fuel the reactions in this stage. Here, CO2 molecules are broken down and
converted into sugars and other compounds. The Calvin Cycle is repeated twice in order to yield
one molecule of glucose.

Since the absorbed photon had a specific
energy, this absorption occurs at a specific
wavelength in the spectrum
Leaf
Some organisms, such as plants, can trap the energy in sunlight through photosynthesis) and
store it in the chemical bonds of carbohydrate molecules
The principal carbohydrate formed through photosynthesis is glucose.
Other types of organisms, such as animals, fungi, many protozoa, and a large portion of bacteria,
are unable to perform this process. Therefore, these organisms must rely on the carbohydrates
formed in plants to obtain the energy necessary for their metabolic processes.
Cells take the carbohydrates into their cytoplasm, and through a complex series of metabolic
processes, they break down the carbohydrates and release the energy
In other words:
Photosynthesis:
• Photosynthesis is the process by which the energy of sunlight is converted
into the energy of glucose
Steps in photosynthesis
1- light hits leaf
2- hits chloroplasts
3- water (h2o) is present because of water from roots carry it to viens
4- carbon dioxide enters through stomata (the thing that decides what enters/leaves)
5-chemical reaction with carbon dioxide, water, and chlorophyll
6- oxygen passes through leaf and leaf makes glucose (extra stored)
7- mitochondria- breaks down oxygen and glucose for energy and the carbon dioxide is released
8- in animals mitochondria takes glucose and combines it with oxygen=energy Carbon taken in
blood stream to be exhaled

Make a Venn diagram on photosynthesis and cellular respiration
Warm up:
Describe everything you know about cellular respiration.
Objective:
Use direct and indirect evidence to describe the relationship between photosynthesis and
cellular respiration within plants – and between plants and animals
Photosynthesis:
• Photosynthesis is the process by which the energy of sunlight is converted
into the energy of glucose
What is photosynthesis?
What are the important parts?
What is the chemical formula of photosynthesis?
PHOTOSYNTHESIS
Autotrophic Process: Plants and plant-like organisms make their energy
(glucose) from sunlight.
Stored as carbohydrate in their bodies.
6CO2 + 6H2O + sunlight  C6H12O6 + 6O2
Photo-synthesis
means "putting together with light."
Plants use sunlight to turn water and carbon
dioxide into glucose. Glucose is a kind of sugar.
Plants use glucose as food for energy and as a
building block for growing.
Autotrophs make glucose and heterotrophs are
consumers of it.

Autotrophs & Heterotrophs
Cellular respiration is the process by which the chemical energy of "food" molecules is
released and partially captured in the form of ATP. Carbohydrates, fats, and proteins can
all be used as fuels in cellular respiration, but glucose is most commonly used as an
example to examine the reactions and pathways involved.
