Ch 28 – Plant Evolution and Classification
A waxy or fatty and watertight layer on the external wall of epidermal cells
Cuticle
A reproductive cell or multicellular structure that is resistant to environmental conditions and that can develop into an adult without fusion with another cell
Spore
A plant embryo that is enclosed in a protective coat
Seed
The specialized conducting tissue that is found in higher plants and that is made up mostly of xylem and phloem
Vascular tissue
The type of tissue in vascular plants that provides support and conducts water and nutrients from the roots
Xylem
In vascular plants, the tissue that carries organic and inorganic nutrients in any direction, depending on the plant’s needs
Phloem
The three groups of plants (liverworts, hornworts, and mosses) that lack specialized conducting tissues and true roots, stems, and leaves
Nonvascular plant
A plant that has true roots, stems, and leaves and a vascular system composed of xylem and phloem which are specialized tissues that conduct materials from one part of the plant to another
Vascular plant
A plant that produces seeds
Seed plant
A woody, vascular seed plant whose seeds are not enclosed by an ovary or fruit
Gymnosperm
A flowering plant that produces seeds within a fruit
Angiosperm
In plants and algae that have alternation of generations, the diploid individual or generation that produces haploid spores
Sporophyte
In alternation of generations, the phase in which gametes are formed; a haploid individual that produces gametes
Gametophyte
The alternation of sexual reproduction and asexual reproduction in certain plants and animals
Alternation of generations
A plant that has no vascular tissue and absorbs nutrients and water from the soil through root-like hairs; examples include mosses and liverworts
Bryophyte
A member of the phylum Hepatophyta, a unique group of bryophytes that grow close to the ground in moist, shady areas and that are characterized by unique structures on the gametophytes
Liverwort
A member of the phylum Anthocerophyta, a unique group of bryophytes that grow close to the ground in moist, shady areas and that are characterized by long, thin, photosynthetic sporophytes
Hornwort
A cone-like structure of sporangia-bearing leaves
Strobilus
A horizontal, underground stem that provides a mechanism for asexual reproduction
Rhizome
The tightly coiled new leaves of a fern
Fiddlehead
The leaf of a fern or palm
Frond
To begin to grow from an embryo into a mature form
Germinate
A young plant grown from a seed
Seedling
In plants, a seed bearing structure; in animals, a photoreceptor within the retina sensitive to bright light
Cone
A tree that sheds and regrows its leaves in response to seasonal changes
Deciduous
In the female reproductive system of animals, an organ that produces eggs; in flowering plants, the lower part of a pistil that produces eggs in ovules
Ovary
The embryonic leaf of a seed
Cotyledon
A monocotyledonous plant; a plant that produces seeds that have only one cotyledon
Monocot
A dicotyledonous plant; an angiosperm that has two cotyledons, net venation, and flower parts in groups of four or five
Dicot
In plants, a bundle of vascular tissue that transports fluids and nutrients; in animals, a vessel that carries blood to the heart
Vein
A parallel arrangement of veins; typical of the leaves of monocots
Parallel venation
A nonparallel, branching network of veins that is typical of the leaves of dicots
Net venation
