Term
Four Major Groups of Plants

Term
Structure of a Complete Flower
Definition
1. Caylx --> sepals 2. Corolla--> petals 3. Androcium--> stamen (filament+anther) 4. Gynoecium --> carpels (ovary, stigma, style)
Term
Apical meristem
Definition
the location of the apical meristem is at the growing tops of plants, which helps lengthen them; has protoderm (becomes epidermis), procambium (becomes vascular tissue), and ground meristem (becomes ground tissue)
Term
Hypocotyl
Definition
Region of the embryo that emerges first and becomes established as the primary root
Term

Definition
Emerges later and becomes the shoot system
Term
Node
Definition
the point on the axis where the leaf attaches
Term
Internode
Definition
Region on the axis between two nodes
Term
Leaf Blade
Definition
Unique for each species of plant and the veins that run through the leaf blade largely determine the shape.
Term
Sessile Attachment
Definition
When the leaf blade attaches to the axis directly
Term
Petiole
Definition
When a leaf blade isn't connected directly to the stem/branch

Peduncle
Definition
The stalk of a single, solitary flower
Term
Receptacle
Definition
The expanded peduncle that forms a platform and holds the floral whorls
Term
Calyx
Definition
The outermost whorl made up of individual units called sepals; protects the flower bud and is normally green in color;
Term
Sepals
Definition
Individual units that make up the calyx
Term
Corolla
Definition
Made up of individual units called petals; normally apprears brightly colored and attracks pollinators
Term
Perianth
Definition
Made up of the calyx and corolla and cosidered to be non-essential flower parts
Term

Definition
Make up an undifferentiated perianth
Term
Bracts
Definition
Additional leaf-like structures found outside the calyx; modified floral leaves
Term
Androecium
Definition
Made up of individuals parts called stamens
Term
Stamen
Definition
Make up the Androecium; consist ofa stalk (filament) that ends in a two-four lobed anther
Term
Anther
Definition
the site of pollen formation
Term
Gynoecium
Definition
Consists of individual units called carpels;
Term
Carpel
Definition
Several carpels make up a pistil; consists of the reproductive unit called an ovary;
Term
Ovule
Definition
Develop the eggs
Term
Stigma
Definition
Receptive part of a carpel; collect and hold pollen and a style
Term
Style
Definition
Connects the stigma and ovary
Term
Dioecious
Definition
Plant either grows male or female parts but not both
Term
Inflorescense
Definition
The peduncle, instead of terminating in a single flower, usually brances off and holds a collection of flower arranged in various fashions
Term
Pedicel
Definition
the stalk of an individual flower
Term
Hypogynous/Superior
Definition
An ovary rest at a higher level on the receptacle compared to other parts of the flower; ex. A tomato
Term
Epigynous
Definition
The ovary is inferior and located beneath the sepals, petals, and stamens; ex. Bluberry
Term
Perigynous
Definition
The ovary is neither inferior or superior but semi-inferior; ex. Apple blossom
Term
Compound Ovary
Definition
Develops from the fusion of two or several individual carpels; ex. Oranges, okra
Term
Simple ovaries
Definition
Individual carpel without any fusion; ex. Single compartment in bean pod
Term
Cotyledons
Definition
Seed leaves; provides the basis for classification 1 in monocots and 2 in dicots.
Term
Lateral meristem
Definition
appears as a cylinder running laterally through the entire plant except at the tips, contributes to the increase in the plants diameter; secondary growht; Vascular cambium and cork cambium
Term
Intercalary meristem
Definition
the location of ths meristem is at the nodal regions of grasses, which contributes to the re-growth of the grasses after cutting.
Term
Vascular cambium
Definition
Leads to secondary xylem (forms most of the wood) and secondary phloem (forms part of the inner bark)
Term
Xylem
Definition
Forms most of the wood; part of the vascular tissue; conducts water and minerals
Term
Phloem
Definition
forms part of the inner bark; part of the vascular tissue; conducts dissolved sugars
Term
Cork cambium
Definition
form the periderm (cork, bark)
Term
Annual
Definition
most weeds and beans complete their life cycle in one growing season
Term
Biennials
Definition
Need two year; first year is necessary to complete their vegetative growth and to store food in the underground part that will regenerate during the second year to complete the reproductive process;
Term
Perennials
Definition
Normally take several years to complete their vegetative growth; once they start their reproductive stage, these plants flower and produce fruits at a certain season every year
