|dermal tissue||The protective covering of plants; generally a single layer of tightly packed epidermal cells covering young plant organs formed by primary growth.|
|ground tissue||tissue between the dermal tissue and vascular tissue of a non-woody plant that functions in photosynthesis, storage, and support|
outer layer of skin
|root hair||A tiny extension of a root epidermal cell, growing just behind the root tip and increasing surface area for absorption of water and minerals.|
|vascular bundle||clusters of xylem and phloem tissue in stems and leaves of plants|
|stoma||pl. stomata; a minute epidermal pore in a leaf or stem through which gases and water vapor can pass|
|xylem||Vascular plant tissue consisting mainly of tubular dead cells that conduct most of the water and minerals upward from roots to the rest of the plant.|
|phloem||tissue that conducts synthesized food substances such as sugar (e.g., from leaves) to parts where needed|
|transpiration||the emission of water vapor from the leaves of plants|
|adventitious root|| |
root growing in an unusual location e.g. from a stem
A flowering plant, which forms seeds inside a protective chamber called an ovary.
seed plant that bears its seeds directly on the surfaces of cones
|pollination||transfer of pollen from the anther to the stigma of a plant|
The terminal pollen sac of a stamen, inside which pollen grains with male gametes form in the flower of an angiosperm.
|pistil||the female ovule-bearing part of a flower composed of ovary and style and stigma|
|stamen||The pollen-producing reproductive organ of a flower, consisting of an anther and a filament.|
