| In a plant, the hormonal inhibition of axillary buds by a terminal bud. | ||
| An embryonic shoot present in the angle formed by a leaf and stem. | ||
| In plants, a cell with a thick primary wall and no secondary wall, functioning mainly in supporting growing parts. | ||
| In a plant, a cell connected to a sieve-tube member whose nucleus and ribosomes provide proteins for the sieve-tube member. | ||
| In plants, the ground tissue system of a root, made up mostly of parenchyma cells, which store food and absorb minerals that have passed through the epidermis. | ||
| The first leaf that appears on an embryo of a flowering plant; a seed leaf. Monocot embryos have one; dicot embryos have two. | ||
| In plants, a waxy coating on the surface of stems and leaves that helps retain water. | ||
| The outer protective covering of plants. | ||
| A term traditionally used to refer to flowering plants that have two embryonic seed leaves, or cotyledons. | ||
| The innermost layer (a one-cell-thick cylinder) of the cortex of a plant root; forms a selective barrier determining which substances pass from the cortex into the vascular tissue. | ||
| In plants, the tissue system forming the protective outer covering of leaves, young stems, and young roots. | ||
| In plants, a long, slender sclerenchyma cell that usually occurs in a bundle. | ||
| A specialized, living plant cell with thin primary walls; arranged end to end, such cells collectively form phloem tissue. Also called sieve-tube member. | ||
| A tissue of mostly parenchyma cells that makes up the bulk of a young plant and is continuous throughout its body; fills the space between the epidermis and the vascular tissue system. | ||
| A specialized epidermal cell in plants that regulates the size of a stoma, allowing gas exchange between the surrounding air and the photosynthetic cells in the leaf. | ||
| The portion of a plant stem between two nodes. | ||
| The main site of photosynthesis in a plant; consists of a flattened blade and a stalk (petiole) that joins the structure to the stem. | ||
| The green tissue in the interior of a leaf; a leaf's ground tissue system; the main site of photosynthesis. | ||
| Flowering plants whose embryos have a single seed leaf, or cotyledon. | ||
| The point of attachment of a leaf on a stem. | ||
| A structure consisting of several tissues adapted as a group to perform specific functions. | ||
| In plants, a relatively unspecialized cell with a thin primary wall and no secondary wall; functions in photosynthesis, food storage, and aerobic respiration and may differentiate into other cell types. | ||
| The portion of a plant's vascular tissue system that conveys food (sugars) throughout a plant. This tissue is made up of sieve-tube members. | ||
| Part of the ground tissue system of a dicot plant; fills the center of a stem and may store food. | ||
| A horizontal stem that grows below the ground. | ||
| All of a plant's roots, which anchor it in the soil, absorb and transport minerals and water, and store food. | ||
| An outgrowth of an epidermal cell on a root, which increases the root's absorptive surface area. | ||
| In plants, a very hard, dead sclerenchyma cell found in nutshells and seed coats; a stone cell. | ||
| In plants, a supportive cell with rigid secondary walls hardened with lignin. | ||
| All of a plant's stems, leaves, and reproductive structures. | ||
| A food-conducting cell in a plant. Chains of sieve-tube members make up phloem tissue. | ||
| The part of a plant's shoot system that supports the leaves and reproductive structures. | ||
| A modified leaf used by some plants to climb around a fixed structure. | ||
| Embryonic tissue at the tip of a shoot, made up of developing leaves and a compact series of nodes and internodes. | ||
| An integrated group of cells with a common function, structure, or both. | ||
| One or more tissues organized into a functional unit within a plant or animal. | ||
| A tapered, porous, water-conducting and supportive cell in plants; makes up the water-conducting, supportive tubes in xylem. | ||
| An enlargement at the end of a rhizome in which food is stored. | ||
| A strand of vascular tissues (both xylem and phloem) in a plant stem. | ||
| The central cylinder of vascular tissue in a plant root. | ||
| A system formed by xylem and phloem throughout the plant, serving as a transport system for water and nutrients, respectively. | ||
| In plants, a vascular bundle in a leaf, composed of xylem and phloem. | ||
| A short, open-ended, water-conducting and supportive cell in plants; makes up the water-conducting, supportive tubes in xylem. | ||
| A specialized, dead plant cell with lignin-containing secondary walls, arranged end to end, forming xylem tissue. | ||
| The nonliving portion of a plant's vascular system that provides support and conveys water from the roots to the rest of the plant. It is made up of vessel elements and/or tracheids, water-conducting cells. |
