From Seed to Seed: A Pictorial Story Showing How a Bean Plant Grows: Part 1 The Developing Bean Plant Glossary

facing away from axis (stem), typically the lower surface of leaves

natural separation of plant structures such as leaves or petals

facing towards axis (stem), typically the upper surface of leaves

the terminal structure of a stamen where the pollen develops

areas of rapid cell division found at the ends of shoots or roots

the angle between a leaf and stem, an area not a structure

actively growing or dormant bud found in an axil, may be vegetative or floral

the upper petal of a bean flower

in beans, a single chamber that makes up the pistil

the structure that surrounds plant cells made up of primarily cellulose, providing structural support and protection

the green organelles responsible for photosynthesis

a tissue made up of more than one cell type

a fully divided leaf, each division is a leaflet

ground tissue found in stems between the epidermis and vascular bundles

a very modified leaf that stores energy for the developing embryonic plant

thin-walled cells that surround all plant parts, most commonly the epidermis

the region above the cotyledons and below the first true leaves

the outer cells of plant organs

long and strong cells that have thick hard walls for support

the structure that holds the anther up, a subunit of a stamen

the opening of a flower when it is mature

The reproductive organ in plants

the mature ovary with seeds inside

one of the three tissue systems in plants, often storage cells or photosynthetic cells, in older organs, may have fibers

the attachment point between the ovary and the seed, on mature seeds, it is often a different color than the seed coat

the area between the cotyledons and the root

the two lower petals of a bean flower that look like a boat keel together

areas of rapid cell division that add width to stems or roots

flattened plant organ responsible for a majority of photosynthesis

in beans, each leaf is divided into three leaflets except for the first leaves that grow after the cotyledons, which have only one

a member of the bean family of plants

thick-walled cells found often in the seed coat of plants; they are elongated in shape

plants consist of five diverse structures; these are the leaves, stems, roots, flowers and fruits

the basal portion of a pistil which holds the ovules which will become the bean fruit

the structure that holds the egg and becomes the seed and includes the seed coat

thin-walled cells that are alive and serve many functions such as photosynthesis or storage

a low-density product made from volcanic glass; water adheres to its surface but is not absorbed

one of the two vascular tissues; responsible for the movement of sugars from where they're made to where they're needed or stored

the central structure in a flower that is made up of a stigma, style, and ovary

the central group of cells in stems that act as filler; composed of living parenchyma cells

the structure that holds sperm for reproduction, often too small to see without a microscope

the embryonic root inside of the seed

the plant organ that absorbs water and nutrients for the other organs

the growing tip of a root

thin-walled epidermal cells that increase the surface area of a root; they aid in absorption of water and minerals

an instrument that uses a beam of electrons to scan over the surface of a sample. This allows for high magnification and depth

thick-walled cells that are dead at maturity, most often for protection from being eaten

thick-walled, long cells that are dead at maturity

the embryonic plant, cotyledons, and seed coat

the outermost cells that protect the embryo and cotyledons 

a bean fruit

the natural process of dying that occurs in many places in the plant during development

a small leaflike structure at the base of a flower

the growing tip of a stem

a tissue that is made up of one cell type providing the same function

the structure that consists of an anther and filament

small units of stored complex sugars within cells

the organ that supports the leaves, flowers and fruits, and moves materials between organs

the terminal end of a pistil where pollen must land for pollination

the column-like area between the stigma and ovary of a pistil

non-living cells in the xylem that conduct water and dissolved minerals

narrow, non-living tracheary elements

sometimes called hairs, these grow from the epidermis and can be diverse in shape and function

a leaf that is dissected into three parts

a leaf that technically is divided into only one part, technically called a leaflet

the veins of a plant that are made up of xylem and phloem

wide tracheary elements (non-living)

one of the two vascular tissues, responsible for the movement of water and dissolved minerals

the Greek letter mu is used as a label representing one millionth in the metric system,  μm is then one-millionth of a meter and called a micrometer or micron
