spontaneous generation
|
idea that a living thing could be created from a NON-Living thing
(i.e. a bug could be created from a rock or turtles developed from mud) |
|
characteristics of all living things
|
ALL LIVING THINGS
. are made of cells (one or more) . can move .respond to stimulus .reproduce .perform complex activites called metabolisim .grow, develop and have a life span |
|
unicellular
|
living thing made of one cell
(example - ameoba) |
|
multicellular
|
living thing made of more than one cell (example people, dogs)
|
|
metabolism
|
all chemical activities done by living things (examples: eating, digesting, pooping)
|
|
ingestion
|
when a living thing takes in food (example: when you eat)
necessary for a living thing to perform chemical activities (metabolism) |
|
digestion
|
process where living thing breaks down the food into a simpler substances so it can be used by it for chemical processes
complex carbohydrates are broken down into simple carboydrates to be used as energy by a living thing (example - when food is in your stomach, you are digesting when you eat steak it must be broken down to smaller pieces so your body can use it for energy etc.) ) |
|
respiration
|
when a living thing takes in oxygen and uses it to make energy
|
|
excretion
|
when living thing gets rid of waste
if living thing didn't get rid of waste it could kill the living thing |
|
stimulus
|
any change in the environment (or surroundings) of a living thing
|
|
response
|
any type of REACTION (example movement, change in behavior) from a living thing caused by a change in the living things environment/surroundings
example (when you cover your ears when their is a loud noise, covering your ears is the RESPONSE to the stimulus noise) |
|
all living things RESPOND to a STIMULUS
|
means that they will move, behave or do something when there is a change in their environment or surroundings
|
|
reproduction
|
when a living thing creates the same type of living thing (iexample creating babies, offspring)
something all living things do |
|
sexual reproduction
|
reproduction that requires TWO parents (example puppies and humans are created from two parents)
|
|
asexual reproduction
|
reproduction that requires ONLY ONE PARENT
(example : when bacteria divides into two, or yeast forms a bud that breaks off to form new yeast) |
|
Needs of all Living Things
WE FLOP |
all living things NEED:
"WE FLOP" .Water .Energy .Food .Living Space .Oxygen .Proper temperature |
|
energy
|
needed by all living things
living things use energy for different things (animals use energy to capture food, plants use energy to make their own food) primary source of energy for most living things is the SUN |
|
food and water
|
needed by all living things
FOOD is a source of energy for living things to grow, repair, develop WATER is needed for living things for it perform chemical activies (example digest food, transport waste) and living things are MADE in PART from water |
|
oxygen
|
needed by all living things
living things get oxygen from different sources depending on where they live (example people get it from air they breath, fish get oxygen from water) |
|
living space
|
needed by all living things so they can grow, develop, find the right food and be protected
its limited so living things fight over it (compete) |
|
competition
|
when living things struggle/fight with other living things to get food, water, living space etc
they do this because many of the things they need to survive are limited (not enough for all) |
|
temperture
|
all living things need to maintain proper temperture to survive
|
|
homeostasis
|
ability of living thing to keep conditions INSIDE its body the same eventhough the conditions OUTSIDE of its environment change
(example, people sweat to cool off their bodies in hot weather, dogs pant to cool off in hot weather, snakes will lie in sun to keep warm themselves to maintain proper temperture) |
|
biogenesis
|
idea that living things come only from other LIving things
|
|
plants and energy
|
plants use energy to MAKE its own food
|
|
animals and energy
|
animals use energy to CATCH their food
|
|
inorganic compound |
most inorganic compounds do not contain CARBON
nonliving things are made of inorganic compounds which mean most dont have carbon examples of inorganic compounds are rust,water, ammonia |
|
organic compounds
|
compounds that contain CARBON
most compounds in living things contain carbon organic means life |
|
BIG FOUR ORGANIC COMPOUNDS THAT ARE IMPORTANT FOR LIVING Things
Charlie likes pizza now |
"Charlie Likes Pizza Now"
.Carbohydrates .Lipids (fats/oils) .proteins .nucliec acids |
|
carbohydrate
|
main source of energy for living thing
sources include potatoes, noodles,rice sugar and starch are two forms of carbohydrate large carbohydrates are broken down into smaller carbohydrates during DIGESTION one of the main organic compounds that living things need |
|
sugar
|
type of carbohydrate (remember carbohydrates are the fuel or energy for a living thing)
also called a SIMPLE carbohydrate formed when carbohydrate is broken down into sugar called glucose glucose (also called simple sugar) is then used to make energy if you have to much sugar, more than body needs it is stored |
|
starch
|
type of carbohydrate (remember carbodydrates are the primary fuel/energy for a living thing)
called a COMPLEX carbohydrate it is a sugar that is stored for later use when the body needs it, starch is used for energy |
|
lipids (fats / oils)
|
one of the main compounds needed by living things
used by body for energy and to cushion and insulate organs fats are solid oils are liquid both are lipids |
|
proteins
|
one of the main organic compounds needed by living things
necessary for growth and repair of body produce antibodies that fight infection create hormones needed for growth create enzymes that slow or speed chemical reactions made of amino acids sources include meat,eggs, nuts |
|
amino acid
|
building block of protein
|
|
nucleic acids
|
one of the main organic compounds needed for life
these are the blueprints of life like a set of directions a builder uses to build a house contain information that tells body how to organize amino acids so it builds the right protein two types are DNA and RNA |
|
DNA
|
type of nucleic acid
stores information needed to build a protein tells the amino acids what order they need to be in (what sequence) also carries information that is passed from parent to offspring(child) |
|
RNA
|
type of nucleic acid
"READS" the information in the DNA and guides the building of the protein |
|
saturated fats
|
bad fats from animals that can clog your blood vessels
|
|
unsaturated fats
|
fats from plants that generally dont clog your blood vessels
|
|
digestion
|
when complex carbohydrates are broken down into simple carbodydrates
they way your body breaks down food to get energy for its functions |
