BIOLOGICAL DIVERSITY-2 Flashcards
Define inherited characteristics
Characteristic passed from parent to offspring.
Define Non- inherited characteristics
Characteristics are developed throughout an organisms life.
What is a discrete variation?
There are only two ways something could be
What is a continuous variation?
There are many variations of a characteristic.
True or False: The environment may influence some variation.
True
What is Asexual Reproduction?
Involves only one parent, all the offspring are identical
What is binary fission?
1 of 4 ways of Asexual reproduction.
A single cell splits into two identical cells.
What is Budding?
The parent organism produces a bud which eventually detached and become a new organism.
What is spore reproduction?
Similar to seeds, the parent produces spores which then grows into a new organism.
What is Vegetative reproduction?
How a plant with seeds reproduce: Runners, Cuttings, suckers, tubers
What is sexual reproduction?
-Involves two organisms, a male and a female. (only some can self fertilize)
-The offspring inherit half of each parents genetics.
-Involves gametes which combine and form Zygotes
What are male gametes called?
Sperm
What are female gametes called?
Eggs or ova
What are the stages of sexual reproduction
sperm+egg
Zygote becomes embryo by dividing over and over(cleavage)
Embryo becomes a multi-cellular organism
How does sexual reproduction happen in plants?
The male and female gametes join during fertilization to produce a zygote.
Most plants have both male and female parts, but some don’t.
