The evaporation of water from plant surfaces, which is capable of pulling water up he plant by bulk flow to the tops of even the tallest trees and is the primary way in which water is transported long distances in plants.
What is Transpiration
100
The numerous perforations in the sieve plate
What is sieve plate pores
100
The explanation for translocation involving the lower solute concentration of sieve tube elements near sinks resulting in a water pressure difference that drives the bulk flow.
What is pressure flow hypothesis
100
Proteins that become activate when they receive a specific kind of signal.
What is receptors
100
Proteins that transport auxin out of cells (most commonly PIN proteins)
What is auxin efflux carriers
200
sausage shaped cells that border stomata and causes the stomata to open and close.
What is guard cells
200
Theses proteins accumulate on sieve plates, and form a "clot" to help prevent the loss of phloem sap. They also bind to pathogens to help ward off infection.
What is P Protein (phloem protein)
200
Internal biological clocks
What is circadian rhythms
200
These transmit messages from many types of activated receptors. Examples include cAMP, inositol triphosphate, and calcium ions.
What is second messengers!
200
A process explaining how auxin primarily flows downward in shoots into roots due to the polar distribution of auxin carriers.
What is polar transport
300
a plant adaptation used to cope with water strew in which a plant drops its leaves.
What is leaf abscission
300
The process where companion cells (and other things) move sugars into sieve tube elements for long distance transport.
What is phloem loading
300
A type of plant chemical signal also found in animals
What is hormones
300
molecules that directly influence cellular responses. This is what causes a cellular response thus ending the cell signaling process.
What is Effectors
300
plant hormones that increase the rate of cell division. Majorly located in root tips.
What is cytokinins
400
Main component of the phloem, arranged end to end to form transport pipes
What is Sieve Tube Elements
400
Place where sugar is produced
What is sugar source
400
The tendency of a plant to grow towards a light source
What is phototropism
400
diverse genes whose expression is largely promoted by auxin
What is auxin-response genes
400
plant hormones produced in apical buds, young leaves, and seed embryos. These hormones promote shoot development, they foster seed germination and enhance stem elongation and flowering.
What is gibberelins
500
The perforated end walls of mature sieve tube elements
What is sieve plates
500
place where sugar is consumed
What is sugar sink
500
The process in which a cell perceives a physical or chemical signal
What is cell signaling
500
a protein that carries the negatively charged form of auxin across a plasma membrane.
What is auxin influx carrier
500
A plant hormone particularly important in plant developmental and stress responses. It is produced during seed growth, flower development and fruit ripening.
