levels of organization
What is the smallest unit of life?

What are the key differences between asexual and sexual reproduction?
one v. two parents, genetically identical v diverse offspring, little time and energy v more time and energy
What adaptations do plant seeds have in order to reproduce better?
some have bristles to attach to fur, some can float in water, some can float in wind
When organisms with favorable traits reproduce successfully?
survival of the fittest
what is artificial selection?
humans breeding plants and animals for specific traits
What is the order of organization from simplest to most complex?
cells - tissues - organ - organ system - organism
What is the genetic product of asexual reproduction?
a genetically identical offspring of one parent
What is the sexual reproduction process in plants?
flowering plants, pollen contains sperm cells which fertilize the stigma in the flower which reaches the egg cell
A trait that helps an organism survive in its environment.
adaptation
Give an example of an artificialily selected domesticated animal.

artificial selection is guided by humans, natural is in nature
What is an organ system? Give an example
A group of organs working together to perform a specific function. Circulatory system.
What are the advantages of sexual reproduction in animals?
, genetic diversity
What is the impact on population size of asexual reproduction?
extremely fast growth
Give an example of natural selection in giraffes.
longer necks to eat more leaves, camouflage, long tongues
Give an example of artifical selection in farming?
larger tomatos
How do tissues and organs work together?
tissues form organs, and organs work in systems for life functions
The type of asexual reproduction where the offspring grows from a piece of the parents. (Starfish)
regeneration
How can plants reproduce?
asexually or sexually
Who is the scientist known for proposing the theory of natural selection?
Charles Darwin
What is a consequence of artificial selection?
reduced genetic diversity
