25
Q

define resource partitioning

A

division of a resource among 2 or more coexisting species

26
Q

define natural selection

A

when the most suited, the strongest of each species survive

27
Q

formula for diversity index

A

diversity index = #of runs/ # of specimens

28
Q

define heritable characteristics

A

characteristics passed through generations

29
Q

define non-heritable characteristics

A

acquired characteristics

30
Q

define discrete variation

A

differences in characteristics that have a defined form (either/or, yes or no, black and white)

31
Q

define continuous variation

A

differences in characteristics that have a range of possibilities (i.e shoe size)

32
Q

2 properties of asexual reproduction

A
  • requires 1 parent

- offspring is identical to the parent

33
Q

4 types of asexual reproduction

A

Binary fission, budding, spore reproduction and vegetative

34
Q

one cell organisms reproduce like this, they split exactly in 2 producing 2 identical individuals

A

Binary fission

35
Q

the parent produces a smaller version of itself

A

budding

36
Q

define spore reproduction

A

spores are like seeds, but they are produced by parent cell division that develop

37
Q

define vegetative reproduction

A

plants that reproduce without seeds. They create roots or runners

38
Q

define gamete

A

a cell with the role of joining with another gamete during reproduction

39
Q

define egg in sexual reproduction

A

the female gamete

40
Q

define zygote

A

Unicellular organism formed through fertilization

41
Q

define population

A

members of the same species ok tyr same area sharing resources

41
Q

how are organisms named

A

using genus and species

42
Q

define cleavage

A

process in which zygote divides itself repeatedly

43
Q

where is pollen found

A

stamen

44
Q

define fertilization

A

union of the 2 gametes

45
Q

sperm+egg= ________—> _______—>_______—>________

A

fertilization, zygote, cleavage, embryo

46
Q

what contains the MALE gametes of a plant

A

pollen

47
Q

define sperm

A

male gamete

48
Q

what is an embryo

A

new multicellular life form

49
Q

define cross-pollination

A

when the pollen of one plant is carried to the stigma of another

50
Q

what is the male part of the plant

A

stamen

51
Q

where are ovules found

A

pistil

52
Q

where are the FEMALE gametes of a plant

A

ovules

53
Q

disadvantage of sexual reproduction

A

energy

54
Q

how does pollination occur

A

when pollen is transferred from the anther of the stamen to the stigma of a pistil

55
Q

disadvantage of asexual reproduction

A

no variation, no different adaptations

56
Q

define cross-fertilization

A

when a grain of the transferred pollen produces a tube that goes down the style into the ovary

58
Q

where is the female part of a plant

A

pistil

58
Q

advantage of asexual reproduction

A

fast reproduction, many offsprings

59
Q

advantage of sexual reproduction

A

variation, adaptation, survival
