Botany Flashcards
Bryophytes
Simple non vascular plants such as mosses
CO2
Carbon dioxide. A simple inorganic molecule comprised of one carbon atom and two oxygen atoms. A by-product of respiration.
Angiosperms
Flowering, seed-bearing, vascular plants
As op. to: gymnosperms, ferns, nonvascular
Cone
Male pollen-bearing and female ova-and-seed-bearing organs of conifers
Cuticle
Waxy protective coating of a leaf
Dispersal
Movement away from location of parent; of plants, typically animal, wind, or water dispersal
Enzyme
A protein that catalyzes a chemical reaction, either helping build or break down a compound
Epidermis
(Of a leaf) outer layer of cells
Evergreen
(Of a plant) the characteristic of retaining functional leaves for at least a full year
(ex: broadleaf evergreen tropical trees, or coniferous needle leaved evergreen trees of the boreal forest)
Ferns
A specific group of nonflowering, nonseed-bearing, vascular plants
Flower
A reproductive unit of a plant (compare with inflorescence)
Forb
An herbaceous, non-grasslike plant…ex: sunflower, iris, violet
Genet
A genetic individual, often made up of multiple vegetative units, sharing resources to some degree (as op to: ramet
Gymnosperms
Nonflowering, seed-bearing, vascular plants ex pines
Inflorescence
The flowering branch; a collection of flowers developed from a single branch ; either a head (ex sunflower), branched, or spike like
Internode
A section of a stem connecting nodes; the region of the stem associated with elongation
Leaf
Primary photosynthetic organ of a plant
Know: classes of shape, simple v. Pinnately compound v. Palmately compound, paired/opposite v. Alternate
Lichen
A type of organism formed by a mutualistic symbiosis btwn lichen-forming fungi and algae. Algae provide photosynthesis, fungus provides mineral nutrients from enviro. Shape can be: crustose, foliose and fruticose growth forms are flat or crust like, leafy, and branching architectures
Life Form
The characteristic vegetative form or appearance of a species at maturity (tree, shrub, herb, etc)
Margin
(Of a leaf) The outer edge: entire, serrated, lobed.
Meristem
Tissue undifferentiated cells that divide and thereby facilitate growth. Vascular cambium is a type.
Mitochondrion
organelle in plant and animal cells responsible for cellular respiration, the breakdown of complex molecules into ATP, the form of energy that can be used by cells.
