Length of the canine
Term

Definition

-non-seed tracheophyte

-simple vascular tissue with xylem and phloem

-adventitious roots originating from a a rhizome

-leaves with veins

-gamete needs H2O to swim to egg

-sporophyte independent to gametophyte

-homospory and heterospory

Term
Bryophtyes
Definition

-non-tracheopyte

-no true vascular tissue

-no roots, only rhizoids

-male gamete sperm require H2O to swim to the gamete egg

-sporophyte dependent on gametophyte

-homospory

Term
Independent assortment
Definition
Duringgamete formation, different pairs of alleles segregate independently of each other.
Term
Self-fertilization
Definition
Both egg and pollen come from same plant
Term
Gregor Mendel
Definition
Austrian monk + plant breeder discovered basic principle of genetics
Term
Cross-fertilization
Definition
Brushing pollen from one pl ant onto another plant on stigma (to cross or to outbread)
Term
Law of Segregation
Definition
The 2 alleles for each trait segregates during gamet formation and then unite randomly one from each parent @ fertilization.
Term
Angiosperm
Definition

-seed is withing ovaries of flowers

-female gametophyte develops within the ovule. pollen grains carry male gametophyte.

-sporophyte dominant. gametophyte very reduced

Term
Embryophyte
Definition

-embryo is protected by tissue of parent plant

-this is the defining characteristic of what plants are

Term
What is a plant?
Definition

-eukaryotic/autotroph multi-cellular organism capable of photosyntehsis

-an embryophyte

-cellulose-based cell wall, large vacuoles, chloroplasts

-two multicellular: diploid and haploid

Term
Meristems
Definition
Undifferentiated cells at apices and assorted patches within plant body
Term
Apical meristems
Definition
Primary growth
Term
Lateral meristems
Definition
Secondary growth
Term
Three major tissue types

Dermal, Ground, Vascular

Term
Repetitive formation of few major organ types
Definition
roots, stems, leaves, buds, flowers
Term
Secondary growth
Definition
vascular cambium thickens stems and roots
Term
Seasonal difference in water available result in...
Definition
...different diameter vessels (visible as "annual rings")
Term
Sexual reproductive structures are contained in where?
Definition

Term
Phloem loading includes...
Definition
...both symplastic and apoplastic trasfer from mesophyll cells
Term
Most plants have few connections between phloem and adjacent mesophyll cells, which...
