What temperture range do most ag crops germinate?

59-95

Which of the following is a method os asexual reproduction in which roots are generated on the stem before being severed for plants?

layering

type of asexual reproduction in which parts of plants are removed from a parent plant and then rooted to form a new plant

cuttings

pollination that occurs through wind, gravity, and/or water is considered

abiotic pollination

the female gamete of angiosperm plants is

egg cell

method of asexual propagation of plants in which you unite two plants so they grow as one

grafting

the reproduction of a new plant using vegetative parts to make a clone is called

asexual reproduction

vegetables are edible plant structures that devleop from

stem, roots, leaves

a fruit that develops, in part, from something other than the ovary wall is called

accessory fruit

fruits develop froma ripened

ovary wall of an angiosperm flower

pore space accounts for what percentage of soil

50

what material is used to increase pH levels

lime

what material is used to decrease pH levels

sulfer

what is the fineness or coarseness of a soil based on relative percentage of san, silt, and clay in soil

soil texture

the suitability of a soil for gowing vegetation; based on ease of tillage

soil tilth

what stage of germination is the activation period

Stage 1

generally tillage ? soil quality over time

decreases

the entire fruit wall that develops from the ovary wall is the

pericarp

a ? is a dry dehiscent fruit that spilts open on one side

follicle

Self pollination ? genetic variability over generations

decreases

Stage ? of germination is where water uptake slowed to almost a halt

2

? oxygen inhibits germination in seeds

low

dormant seeds perform

cellular respiration

germination is an ? process

aerobic

? is where storage reserves are above the soil surface

epigeal

? is where storage reserves are below the soil surface

hypogeal

self pollination within the same monoecious plant or plant with perfect flows is called

autogamy

monocot cotlydon

1 thin seed leaf

coleoptile

protective sheath covering shoot during emergence

plumule

contains the embryonic foliar leaf and stem, develops nto the emergent shoot

pericarp

fruit wall that develops from ovary wall, fused to seed coat in monocots

endosperm

carbohydrates and other energy containing compounds that the embryo uses during germinationco

cotyledon

seed leaf

hypocotyl

region of stem in a plant embyro that is below the cotyledon

coleorhiza

a protective covering around the

radicle

radicle

embryotic root that develops into primary root

pedicle

the stalk of an individual floret on an inflorescence

plumule

contains the embryonic foliar leaf and stem, develops into the emergent shoot

hypocotyl

internode between the cotyledons and embryotic root (radicle)

radicle

embryonic root that develops into primary root

hilum

scar that results from sperate of the sedd from the ovary wall

cotyledon

seed leaf, dicots have 2

seed coat

outer layer of a seed

mycropyle

scar where pollen tube entered the ovule

raphe

ridge that runs along the edge of the seed
