  • Front
  • Back
Atoms
Smallest part of matter. Building block of all matter.
Molecules
A substance that combines two or more atoms.
Compound
A substance made of two or more different elements.
Protons
Positive charge (Part of Atom)
Electrons
Negative charge (Part of Atom)
Neutrons
Neutral charge (Part of Atom)
Element
Substances that contain one type of atom. 92 elements exist in nature.
Organic Molecules
Organic Molecules that contain at least one carbon and one hydrogen.
C on Periodic Table
Carbon
H on Periodic Table
Hydrogen
Inorganic
All other molecules that do not fit the definition of organic.
Proteins
A LARGE organic molecule made up of Carbon, Hydrogen, Oxygen and Nitrogen.
Carbohydrates
An organic molecule that stores and releases useable energy. It is ring shaped.
Lipids
Huge organic molecule. Important for membrane maintenance and construction. Lipids are Fats
Nucleic Acids
A huge organic molecule used to store information to make other molecules. Made out of nucleic bases
Amino Acids
The building blocks of proteins.
Glucose
building block of carbohydrates. Ring shaped. Chemical formula C6H12O6. Main source of energy
C6h1206
Chemical formula for glucose
Enzymes
A type of protein used for chemical reactions that breakdown or synthesize molecules
Homeostasis
abillity to maintain balance
Digestion
breakdown
Synthesis
put together
Optimum point
highest point on a graph
Ph
measures how acidic or basic something is
Bases
ph of 8-14
Ph paper
is what we use to measure the the Ph
Neutral
water
nerutralilze
to cancel eachother out. An acid will neutralize a base
indicator
things we use to test for certain substances.
Iodine
Benedicts
indicator for starch
iodine
indicator for glucose
benedicts
prokaryotic cells
basic type of cell that does not have a nucleus
eukaryotic cell
basic type of cell that has a nucleus
plant cell
eukaryotic cells that have chloroplasts and a cell wall
animal cell
eukaryotic cell that does not have a cell wall or chloroplasts
organelle
a specialized part of the cell that has it's own function
nucleus
is the brain of the cell- contains all the DNA
mitochondria
maze like organelle that produces the ATP the body needs through respiration.
cytosol
a jelly like substance inside the cell
chloroplast
a coin like organelle that only exists in plant cells so they can complete photosynthesis
Cell membrane
An organelle considered the bouncer of the cell because it balances what can go into and out of the cell
Photosynthesis
Sunlight+Water+ Carbondioxide = Glucose + Oxygen
Passive transport
High --> Low
Do not need ATP
Active Transport
Low--> High
Uses ATP
Diffusion
transfer of materials in and out of the cell that goes from a high or a low concentration
Glucose, water can diffuse
Starch and proteins cannot
Osmosis
transfer of water in and out of the cell
stomata
2 special cells that regulate the amount of carbobn dioxide and oxygen that enter and exit that leaves
Why is photosynthesis important?
Because it helped change the earths atmosphere by creating oxygen so humans can live
Chlorophyll
The green substance in chloroplasts that helps plants capture sunlight so they can finish photosynthesis.
what is locomotion?
the ability of organisms to move themselves.
What is transport?
the ability to move materials from one area to another.
What is the difference between locomotion and transport?
locomotion is moving yourself and transport is moving something else.
What are some mechanisms organisms use for locomotion?
psuedopods, flagella, cillia, legs.
In the beginning of time the earth was mostly made of nitrogen and carbon dioxide. How did photosynthesis change that?
Plants changed the carbon dioxide into oxygen and made it possible for humans to grow.
How does photosynthesis and respiration work together?
the waste product of one is the raw material for the other.
