1what is the purpose of leaf area management
promotes early leaf development
2early planting pro
more time to grow
3starter fertilizer pro
more food to grow
4range burning pro
controls weed
5moisture management
to keep stomata open
6moisture conservation practices
minimize wastefuul evaporation from the soil
7 nitrogen promotes
leaf growth
8fertilaztion is needed for
chlorophyll
9respiration
biological oxidation of sugars to release stored energy
10respiration occurs in
all living cells
11aerobic respiration
complete respiration in the presence of o2
12reverse ps
c6h12+CO2 -> 6CO2+6H2O + energy
13reverse photosythesis involves
50 reactions
14each reaction in reverse photosynthesis is controlled by
separate enzymes
15ATP (aden)
used for many processes, many other complex plant compounds, root growth/ nutrient uptake
16intermediate compounds provide the … for many other complex plant compounds
carbon skeleton
17nearly all plant and animal metabolism is linked to
respiration
18when does respiration occur
all day and night
19what does respiration do to plants dry weight
decreases it
20anaerobic respiration
partial respiration without oxygen
21anaerobic respiration is commonly known as
fermentation
22fermentation produces
alcohol or lactic acid
23what is temperatures affect on respiration
as temp increases resp increases
24 storage of hay and seeds
keep in low mositure
25seeds need to be kept at what moisture level
less than 14 %
26storage of silage
anoerobic respiration, pack well and cover
27storage of fruit
low temp, sealed, low moisture, high cO2
28plants are composed of
proteins, nucleic acid, vitamins, pigments, plant hormones
29compounds are formed using
carbohydrates
30nutrients used in large amounts
macro nutrients
31nutrients used in small amounts
micro nutrients
32what are nutrients used for
plant growht
333 macro nutrients
nitrogen, phosphate, potassium
343 micro nutrients
iron, zinc, magnesium
35absorption
uptake of mineral nutrients and water through root hair cell membranes
36mineral nutrients is active uptake that
requires energy of ATP from respiration
37what controls the energy of nutrients from the soil into roots
used to move nutrients from area of low concentration in the soil to high concentration in roots
38what creates the driving force for water movement from the soil into roots
respiration in leaves creates a negative tension in the xylem which is translated from leaf to stem to root
39transport water and mineral nutrients
xylem
40how does water move to the top of the plant
transportational pull
41phloem
sugar moves upward to grains or fruits and downwards to roots
