The next largest taxon used for plants under kingdom; same as "phylum" used in other kingdoms | Division |
Scientists who study plants | Botanists |
Tubes that move water and nutrients throughout some plants | Vascular tissue |
Plants that do not contain vascular tissue; examples: mosses and liverworts | Non-vascular plants |
Plants that contain vascular tissue but produce spores instead of seeds; examples: ferms | Seedless vascular plants |
Vascular plants that may produce seeds in a cone; example: pine tree | Gymnosperms |
Vascular plants that produce seeds by flowers; example: apple trees | Angiosperms |
A term used to describe all non-vascular plants such as mosses, liverworts, and hornworts | Bryophytes |
Root-like structures that anchor mosses | Rhizoids |
Having two stages or reproduction, a gametophyte stage with haploid (n) cells and a sporophyte stage with diploid cells (2n) | Alternation of generations |
A term for all vascular plants | Tracheophyte |
The tissues that transport water and nutrients up the plant (from the roots up the stem and to the leaves) | Xylem |
The tissues that carry food from the leaves to wherever it is needed | Phloem |
The thick underground stems of ferms | Rhizomes |
The leaves of ferns | Fronds |
Brownish spore cases found on the underside of fern fronds | Sporangia |
The leaf part of an embryo that is present in a seed; also called the seed leaf | Cotyledon |
Flowering plant that has only one cotyledon per seed | Monocot |
Flowering plant that has two cotyledons per seed | Dicot |
Female part of the flower | Pistil |
The part of the pistil that contains the egg cells | Ovary |
Male part of the flower | Stamen |
The part of the stamen that produces pollen | Anther |
Small structures that contain sperm cells | Pollen |
In angiosperms, the transfer of pollen from the male anther to the female pistil | Pollination |
The union of sperm and egg | Fertilization |
Undifferentiated plant tissue that is responsible for cell division | Meristematic tissue |
The tissue that makes up the outer surface of a leaf, stem, etc. | Dermal tissue |
Tissue that makes up most of a plant | Ground tissue |
The process of losing water through a plant's leaves | Transpiration |
The waxy coating on leaves | Cuticle |
The middle layer of cells in a leaf that contain chloroplasts | Mesophyll |
Plant organelle that carries out photosynthesis | Chloroplast |
Openings usually on the underside of a leaf that allow carbon dioxide to enter and oxygen and water to escape | Stomata |
Cells on either side of a stoma that cause the stoma to open or close | Guard cells |
Part of a plant stem often used in storage | Pith |
A part of a plant stem used to store sugar and proteins to be used during spring growth | Cortex |
The outside layer of cells on leaves and stems | Epidermis |
Undifferentiated cells between the xylem and phloem that allow for growth | Cambium |
Characteristics that help an organism to survive in its environment | Adaptations |
Roots that grow in unusual places, such as on the stem of a plant | Adventitious roots |
Roots that grow partially in the air and partially in the ground | Prop roots |
A type of gymnosperm that produces seeds in cones | Conifer |
