Here are the terms from this week’s lessons that you will need to be familiar with for your assignments and for the quiz.
|A hormone that regulates seed maturation and responses to changes in water availability.
|A root that emerges from anywhere on the plant other than from the roots.
|A group of flowering plants whose seeds develop inside an ovary.
|A plant that is produced from seed in the spring and dies at the end of the growing season.
|Where a shoot suppresses growth of floral or vegetative axillary buds below the growing point.
|A group of related hormones that regulate many aspects of plant growth and development and are key to stimulating adventitious rooting.
|The ability to respond to a signal, such as a plant hormone.
|An inflorescence with a group of flowers and includes a rachis.
|A group of related molecules that regulate cell division and are key to stimulating adventitious shoot formation.
|When the stem of a plant terminates in a flowering stalk and new stem growth continues from subterminal lateral buds.
|A hormone that occurs within the plant.
|A gas that regulates fruit ripening and plant senescence.
|The application of a hormone to a plant.
|A single flower in a compound inflorescence.
|A reproductive structure in a flowering plant.
|A group of related molecules that regulate seed dormancy.
|A group of plants whose seeds are produced without the protection of an ovary.
|When the apical meristem remains a vegetative meristem capable of forming new nodes and internodes throughout the season. Once the hormonal signals are right, reproductive axillary meristems at the nodes below the apical meristem produce inflorescences.
|The complete flower structure of a plant; includes the flower, pedicle, rachis, and peduncle.
|A hormone made by a plant.
|The short stalk that holds up the flower.
|The large, central stalk that attaches the rachi to the stem of the plant.
|The ability of a plant cell or tissue to detect a hormone that depends on a cell’s physiology at the time the hormone is present.
|A plant that lives for more than two growing seasons (more than two years); perennials may be woody or herbaceous (the latter with underground perenniating structures).
|A signal molecule that regulates growth, development, and responses to environmental and other signals, also known as a plant growth regulator or phytohormone.
|The stalk of a flower that is situated between the peduncle and the pedicel on a compound leaf. Also the name for the central axis on a compound leaf where the leaflets are attached.
|The apical meristem that transforms into the reproductive tissues (the inflorescence) of the plant.
|The action taken by the plant after perception of a signal.
|A regulated process that results in cell death and is associated with leaf fall and death of the plant.
|The process in which the perception of a signal, such as a hormone, is moved within a cell, cell to cell, or throughout a tissue.
|A type of inflorescence with a peduncle, rachis, pedicel, and single flower structure.
|A hormone made by people; can mimic the response of a naturally occurring hormone.
|A growth or turning response to an environmental or other signal such as phototropism (response to light) or gravitropism (response to gravity); can be controlled by auxin and other hormones.
|An inflorescence with multiple flowers originating from a common point.
|A plant that lives for more than a year, has hard rather than fleshy stems, and bears buds that survive above ground in winter. Trees, shrubs, many vines, and bamboo are examples of woody perennials.
