outer covering or "skin" of a plant
tissue between the dermal tissue and vascular tissue of a non-woody plant that functions in photosynthesis, storage, and support
the outer layer of the skin covering the exterior body surface of vertebrates
a small float usually made of cork
tube formed by cells joined end-to-end through which nutrients flow in flowering plants and brown algae
the layer of unmyelinated neurons (the gray matter) forming the cortex of the cerebrum
thin hairlike outgrowth of an epidermal cell just behind the tip
thimble-shaped mass of cells covering and protecting the growing tip of a root
a unit strand of the vascular system in stems and leaves of higher plants consisting essentially of xylem and phloem
the choicest or most essential or most vital part of some idea or experience
hard outer covering or case of certain organisms such as arthropods and turtles
the small openings on the undersides of most leaves through which oxygen and carbon dioxide can move
the woody part of plants: the supporting and water-conducting tissue, consisting primarily of tracheids and vessels
(botany) tissue that conducts synthesized food substances (e.g., from leaves) to parts where needed
something that provides an important central source for growth or development
part of a root system in which roots branch to such an extent that no single root grows larger than the rest
root growing in an unusual location e.g. from a stem
flowering plant with two cotyledons
a monocotyledonous flowering plant
nutritive tissue surrounding the embryo within seeds of flowering plants
The ground tissue of a leaf, sandwiched between the upper and lower epidermis and specialized for photosynthesis.
the emission of water vapor from the leaves of plants
Embryonic plant tissue in the tips of roots and in the buds of shoots that supplies cells for the plant to grow in length.
a process by which a seed embryo develops into a seedling
seed plant that bears its seeds directly on the surfaces of cones
the part of the stamen that contains pollen
the male reproductive organ of a flower
the female ovule-bearing part of a flower composed of ovary and style and stigma
transfer of pollen from the anther to the stigma of a plant
a skin lesion that is a diagnostic sign of some disease

the spore-producing individual or phase in the life cycle of a plant having alternation of generations
an involuntary orienting response
anything (a person or animal or plant or substance) in which an infectious agent normally lives and multiplies
the transport of dissolved material within a plant
promote stem lengthening, helps buds and seeds break dormancy and influence flowering (active in spring)
plant hormone that inhibits cell division in buds and vascular cambium
a plant hormone that promotes root formation and bud growth
