What two things are the product (end result) of photosynthesis?
chloroplast
glucose
oxygen
carbon dioxide
What is the waste product of photosynthesis?
oxygen
glucose
carbon dioxide
chlorophyll
In which way are photosynthesis and cellular respiration similar?
Both processes destroy energy.
Both create energy.
Photosynthesis breaks down sugar while cellular respiration produces sugar.
Both processes transfer energy from one form to another.
What is important about cellular respiration?
It produces energy from the sun.
It forms sugar.
It transforms sugar into a usable form of energy (ATP)
Only plants perform this process.
One molecule needed for cellular respiration is
carbon dioxide
glucose
water
chlorophyll
What do you call organisms that can make their own food?
heterotophs
autotrophs
trophies
What are the ADVANTAGES of organisms that reproduce through asexual reproduction?
Produces offspring that have genetic variability
Allows more diversity
Only one parent is needed
Offspring can adapt easier to environmental changes
Can reproduce quickly as only ONE parent is required.
What are the ADVANTAGES of organisms that reproduce through sexual reproduction?
Produces offspring that have genetic variability
Allows more diversity
Only one parent is needed
Offspring can adapt easier to environmental changes
Offspring are genetically SIMILAR as parents
Which is used to repair or grow cell?
mitosis
meiosis
replication
transcription
Meiosis is the _____.

division of body cells
What is an example of artificial selection?
Letting dogs choose their own mate
Letting plants pollinate on their own
Crossing a labrador and a poodle to create a labradoodle
1. The process of choosing parent organisms for desired characteristics is called
natural selection
Artificial selection
random selection
genetic manipulation
Artificial selection has been a big factor in the evolution of:
Dogs
Panda bears
Snakes
Jellyfish
Which statement is true comparing natural selection and artificial selection?
In natural selection, traits benefit humans and in artificial selection, the traits benefit the species
In natural selection, traits benefit the species and in artificial selection, the traits benefit humans
In natural and artificial selection, the process takes hundreds of years to occur
In natural and artificial selection, nature determines what traits will be passed down to offspring.
Artificial selection is also known as
natural selection
selective hearing
genetic manipulation
selective breeding
