Q

Genetic Engineering

A

the artificial altering of the DNA of an organism or a population of organisms

17
Q

Genetics

A

Heritable traits

Can also be the study of genes

18
Q

Heritable

A

A gentic characteristic that can be passed on
from parent to offspring

eg. Hair color

19
Q

Meristem

A

unspecialized cells in the tips of roots
and shoots that produces new growth
in plants

(cuttings can be used and new plant can grow from the cells)

20
Q

Mutagen

A

An agent that causes a mutation

eg. Chemicals, Radiation

21
Q

Nature vs nurture

A

are people the way they are because of their genetics of their environment

22
Q

Ovule

A

The part that turns into the seed

Female Gamete or egg

23
Q

Pistil

A

The female part of a flower

Includes stigma and ovary

24
Q

Pollen Tube

A

a tube that grows from a pollen grain toward the ovary

25
Recessive Trait
A trait that shows up only when both parents pass on the gene | A ressive trait will not show up when paired with a dominant gene
26
Mutation
A change in the DNA of an organism | Thru natural or artificial causes
27
Reproductive Strategy
The method of reproduction
28
Self-pollination
pollination of a flower with pollen from the same flower
29
Sexual reproduction
Reproductive process involving two sexes or mating types
30
Somatic Cell
Body cells Have 46 chromosomes | Not reproductive
31
Spore
a reproductive structure (like seeds but smaller) | Asexual
32

The male part of the flower | Includes anther and pollen
33
Transgenic
An organism created by moving DNA from one organism to another artificially
34
Variation
differences in characteristics of organisms
35
Zoospore
A spore that uses a tail-like sturcture to move | Asexual
36
Zygospore
A reproductive structure in some fungi | Sexual
37
Zygote
The new cell formed by fertalization | Sexual
