Cuticle
A waxy covering on the epidermis in many species of land plants that acts as waterproofing and
protection
Secondary Compounds
Signaling and protection molecules produced by branches of the main metabolic pathways
Apical Meristems
Localized regions of cell division at the tips of roots and shoots where growth is sustained throughout
the plant's life.
Gametangia
Multicellular organs of early land plants in which gametes are produced
Archegonia
Female gametangia, each of which produce a single egg (gametangia: multicellular organs of early land
plants in which gametes are produced)
Antheridia Placental
Male sex gametangia
Transfer Cells
Specialized cells that enhance the transfer of nutrients from parent to embryo
Bryophytes
Nonvascular plants that do not have an extensive transport system
Stomata
Specialized pores found in all vascular plants, and in mosses and hornworts
Site where dehydration occurs
Regulates the rate of transpiration
Usually open during the day, and closed at night
o light detection- light receptors on the guard cells > stimulates potassium accumulation
o CO2 depletion > Stoma progressively open
o Internal clock, circadian rhythm
Tracheophytes
, Another name for vascular plants which have xylem and phloem
Phloem
Transports photosynthates from the leaves to where they are used or stored
Cells that are arranged into tubes that conduct sugars, amino acids (AA's), and other organic compounds
Gametophyte
The visible structure in nonvascular plants
Usually form ground hugging carpets (like moss). Their body parts are too small to support a tall plant.
Also the absence of vascular tissue
Dichotomous Branching
An arrangement exhibited by some seedless vascular plants in which the shoot apex divides to form two
equal branches
Microphyll
A small leaf, usually having only one vascular strand
Small, spine shaped leaves supported by a single strand of vascular tissue
Homospory
A life cycle in which the spores are of a single type and develop into a gametophyte that bears both
female and male organs
Seed
An embryo packaged with a supply of nutrients inside a protective coat derived from the integument
Haploid
Status of the gymnosperm food reserves
Megaspores
Develop into female gametophytes and only one of the meiotic products survives
Microspores
Develop into male gametophytes
Gymnosperms
Do not form flowers and are naked seeds
Angiosperms
Form flowers and are have enclosed seeds
