Chapter 35
The ability to alter itself in response to its environment, a plant function
What is developmental plasticity?
The charge of most soil particles
What is negatively charged?
This is the part of the plant that is responsible for transporting water through negative pressure and bulk flow
What is the xylem?
This structure of the angiosperm contains pollen (male gametophyte).
What is the anther?
A growth response, toward or away from a stimulus, in plants
What is tropism?
the stem segment between nodes, plants often spike themselves in this area as an evolutionary defense mechanism against herbivores
What are internodes?
The charge of most soil particles
What is negatively charged?
This is the route that sucrose can take through mesophyll cells by going between cells.
What is apoplastic?
This type of angiosperm contains only one cotyledon
What is a monocotyledon?
A common chemical messenger involved in phototropism
What is auxin?
The arrangement of veins, parallel vs branching, a feature of classification
What is one morphological difference between eudicots and monocots?
This is another term for the yellowing of leaves
What is chlorosis?
This is the plant hormone responsible for signaling guard cells in the stomata to close in response to water deficiency in the plant.
What is abscisic acid (ABA)?
Vegetative reproduction that is facilitated/induced by humans.
What is vegetative propagation?
Morphological adaptions to darkness
What is etiolation?
Gas exchange takes place in this part of the leaf, this part is located on the inside of the leaf with no opening to the outside
What are spongy mesophylls?
The process by which mineral cations enter the soil solution and are displaced by other cations, particularly H+
What is cation exchange?
This is the name for the process through which some plants take in CO2 at night rather than during the day, while the stomata remain open during the day when evaporative stresses are the greatest.
What is CAM (crassulacean acid metabolism)?
This is the term used to describe organisms that have been engineered to express a gene from another species.
What is transgenic?
This process is common in post-translational modification of specific amino acids during the central dogma process in signal transduction pathway
What is phosphorylation?
The development of body form and organization in plants
What is morphogenesis?
A biotechnology that harnesses the ability of some plants to extract soil pollutants and concentrate them in other areas of the plant that can be removed for safer disposal.
What is photoremediation?
This is a quantity that includes the effects of solute concentration and physical pressure on water, abbreviated with the Greek letter psi.
One cell in the megasporangium (called the megasporocyte) enlarges and goes through meiosis, resulting in four haploid ___________.
What are megaspores?
Plants respond to this stress by producing high concentrations tolerant solutes
What is one plant response to salt stress?
