Unit 2 Flashcards
Uses energy from the sun or the chemicals in the environment to make food
Producer
Eats other organisms or organic matter
Consumer
Gets energy by breaking down nutrients in dead organisms or animal wastes
Decomposer
Maintenance of a constant internal state in a changing environment
Homeostasis
An example of a consumer
Human / Frog
An example of a producer
Plant
An example of a decomposer
Mushroom
Anything that causes a reaction/change in (any part) of an organism
Stimulus / Response
What is the difference between fats and oils?
FATS are solid at room temperature OILS are liquids at room temperature
Proteins are large molecules made up of smaller molecules
Amino acids
One sugar molecule or a few linking sugar molecules make up
Example : FRUIT
Simple carbohydrates
Molecules consisting of subunits call nucleotides
Nucleic acid
Energy giving nutrients that include sugar, starches, and fiber; contains carbon, hydrogen, and oxygen
Carbohydrates
Living things store extra sugar that are made of hundreds of sugar molecules
Example : Potatoe
Complex Carbohydrates
Found in skin hair and muscles
Proteins
“The blueprints of life” Made up of nucleic acids
DNA
All living things break down food to use…
NUTRIENTS
Compounds that cannot mix with water
LIPIDS
Major energy carrying molecule in a cell
ATP
Adenosine Triphosphate
Name the 6 characteristics of living things
Reproduce Have cells Have DNA Sense and respond Grow and develop Energy
Where do plants get their energy
SUN
Where do humans get energy
Consuming other organisms
What is the difference between growth and development??
Growth get BIGGER
DEVELOPMENT change as you grow
What is the difference between asexual and sexual reproduction
Sexual reproduction cells from 2 parents and offspring share traits of parents EXAMPLES humans, bears
Asexual reproduction 1 parent produces off spring identical to itself
EXAMPLE hydra
What % of human body is water?
70%
What are the 6 main elements that make up living things?
CHOPNS
Carbon Hydrogen Oxygen Phosphorous Nitrogen Sulfur
Give 5 examples of stimuli
Gravity Light Sound Hunger Chemicals
Name 4 things all living things need in order to live
AIR
FOOD
SHELTER
WATER
What are the 5 chemical building blocks of cells
PROTEINS CARBOHYDRATES LIPIDS ATP NUCLEIC ACIDS
What is the cell membrane used for
Acts as a barrier between the inside of the cell and the cells environment.
