Soil And Earth Flashcards
How much energy does glycolysis Release?
Small amount
The Citric Acid Cycle and the Electron transport system
Completely oxidizes glucose, Requires oxygen, Releases a small amount of energy.
Most of the energy that is produced during the aerobic respiration comes from glycolysis
False
What is oxidation
Losing Electros
What is reduction
Gaining Electrons
What parts of the plant cell serve as storage and waste locations?
Vacuole
what things are true about the cell membrane?
it is comprised of a lipid-lipid bylayer, it has both hydrophobic and hyrophilic regions, enzymes can be embedded completely through it , it can maintain ioic (like H+ or proton gradient)
Which organelle is responsible for glucose oxidation and energy productions?
Mitochondria
A Nucleus would Not be found in a
Prokaryote cell
Which organelle can carry out photosyntheseis ?
Chloroplast
Which two components of a plant cell are missing in animal cells?
Chloroplast, Cell wall
monocots have what type of vascularization?
Parrellel vascularization(leaf vains)
dicots have what type of vascularization?
Broad netted leaf vascularization
The endosperm of monocots is Primarily
High in carbohydrates, low in lipids and proteins
What type of seed is a potato
Dicot
What type of plant is wheat
Monocot
Companion cells are associated with which type of vascular system
Phloem
Cytoplasm filled sieve tubes are part of which vascular system?
Phloem
what type of Vascular cell is dead at maturity?
Xylem
what does Xylem Distribute?
Water and minerals
What does phloem distribute?
Carbohydrates and amino acids
Plants control stomates opening and closeing to?
Minimize water loss
Glowers that lack one or more flower parts are called?
Incomplete
Flowers that have both male and female parts are called?
Perfect
meristems are
Undifferentiated and rapidly dividing cells
How does water move through a plant
Generally under tension
The wave nature of light means
As Wavelength increases, Frequency decreases
The energy in a photon of lige
Increases as frequency increases and Decreases as frequency decreases
Plants appear green because
They dont absorb green light
Which of the following is true about light?
Light has wave properties, light has particle properties and blue light is shorter wavelenth than red light
What does the light reaction do?
Splits water into hydrogen and oxygen.
What does the dark reaction do
uses the enzyme rubisco
What does the dark reaction result in?
in Carbohydrate production
what is a chemical that blocks the light reaction?
Atrazine
What does Atp production require?
Atp enzyme, Aproton (h+), ELCTRON TRANSPORT
Which of the following occurs during the light reaction?
Splitting of water into hydrogen and oxygen, Production of NADPH reducing power., movement of protons across the membrane
Why are C3 and C4 plants called this?
The number of carbons in the molecules in which C02 is first fixed
Which plants utilize Rubisco during phosynthesis?
All plants
what does the dark reaction consume?
Nadph and aTP
which plants open their stomates only during the dark?
CAM Plants
C4 plants have higher carbon fixation efficiency than C3 plants because?
They minimize the amount of oxygen near Rubisco
What is a typical expample of Cam plants?
Succulents such as cacti
C3 plants are less efficent at photosynthesis than C4 plants because
Rubisco Recognizes 02 as well as C02
What ?is the most abundant protien on the planet
Rubisco
what provides reducing power?
NADPH
Which soil horizon is the top zone and usually has the most organic matter?
Horizon A
What soil horizon is the parent material of the soild
Horizon C
What are soils useful for?
Environmental filter for water, store plant available water, Store nutrients for plants, Provide an engineering base for strctures.
Are the depths of the a and c horizons the same depth in any soil?
False (no)
Which of the folowhat are the three main types of soil water?
Microscopic, Capillary gravitational
After gravitational water has drained from a soil, the soild is at
Field Capacity

Macronutrients
What are the nutrients that a plant requires least of called?
Micronutrients
how do plants recieve their most essential nutrients
air, water, c02
what nutrient is most limiting in plant growth
Nitrogen
Large pores (macro pores ) in the soild hold water better than small pores (true or false)
False
The water in macro pores is called what?
Gravitational
what are the pores that retain most planet available water?
Capillary pores
