microphylls

type of leaf with no leaf gap

the production of two different spores of different sizes and sex

what is heterospory?

a) increases potential for outcrossing

b)specialization of function permits an increase in efficiency

why is heterospory selectively advantaged?

sporophyte, gametophyte

the sporophyte/gametophyte derives nutrients from the sporophyte/gametophyte after fertilization (COMMON TO ALL PLANTS)

below

in a spenophyte, the buds are above/below the leaf

whisk ferns

the type of fern with no leaves or roots

integument

the protective layer that surrounds the megasporangium

Ginkgo, Cycads, Conifers, Gnetophytes, Angiosperms

The 5 extant seed-plant clades that we covered

meiosis

sporocytes undergo meiosis/mitosis to form gametophytes

monoecious

are conifers monoecious or dioecious?

cycads, ginkgo

Which of the 5 seed-plant clades have motile sperm?

1) vessel elements in wood

2) double fertilization (but 2nd feritilzation in gnetophytes does not produce endosperm)

3) flower-like structures

what are the 3 main similarities between gnetophytes and angiosperms?

perigynous

sepals, petals, stamens are fused around the ovary

micropores (Pollen- the immature gametopyte)

when a microsporocyte undergoes meiosis in an angiosperm, what does it yield?

to serve as nutritive tissue for the developing embryo

what is the main function of the endosperm?

monocots

uniaperturate, scattered vascular bundles, parallel veins, no true secondary growth

cross pollinization

transfer of pollen to a different plant

birds

which pollinator has no sense of smell?

carrion flies

which pollinator does not require any nectar?

moths, bats

which pollinator usually pollinates at night?

bats

which pollinator is color blind?

the elaisome (oil body of the seed) is used as food for ant colonies

why do ants transport seeds?

berries, drupes, pomes

the 3 types of simple, fleshy fruit

follicles, legumes, siliques, capsules

the 4 types of dry, dehiscient fruits

samaras

winged achenes or schizocarps

aggregate fruits

type of fruit derived from one flower with multiple, SEPARATE carpels

respiration

burning/combustion

decay

CO2 returns to the atmosphere through what 3 processes?

CO2 concentration

what do the Vostok Ice Core and Mauna Loa Curve measure?

Pearl Millet, Cocurbita Pepo

name an example of a species that is victim domestication syndrome

lack of genetic diversity leading to increased susceptibility

What was the underlying cause of the southern corn blight epidemic of 1970?

teosinte

what is believed to be the progenitor of maize?

Balsas River Valley

where did teosinte originate?

temporal/spatial, physical, chemical

what the are 3 main categories of plant defense?

alkaloids

caffeine is a type of which secondary metabolite?

terpenoids

taxol is an example of which secondary metabolite?

examples of coevolution

milkweeds and monarchs, wild parsnip and parsnip webworms

dicots

taproot systems are characterstic of dicots/monocots

topsoil, subsoil, soil base

what are the 3 main soil horizons?

horizon A (topsoil)

where is humus found?

CHNOPS, Mg, Ca, K

what are the 9 macronutrients?

Mg and Fe

Chlorosis is caused by a defiency in which nutrient?

air roots that grow out of the mud to provide adequate gas exchange

what are pneumataphores?

the phosphorous cycle

which cycle is considered to be "localized"?

bacteria, lightning, volcanoes, industrial processes

how is nitrogen fixed from the atmosphere?

rhizosphere

the soil that is directly associated with the roots of the plants
