| Question | Answer |
|---|---|
| A main vertical root that develops from an embryonic root and gives rise to lateral (branch) roots. | taproot |
| A bud at the tip of a plant stem; also called a terminal bud. | apical bud |
| (1) A leaflike structure of a seaweed that provides most of the surface area for photosynthesis. (2) The flattened portion of a typical leaf. | Blade |
| A specialized center of body function composed of several different types of tissues. | organ |
| A vascular plant organ consisting of an alternating system of nodes and internodes that support the leaves and reproductive structures. | stem |
| The protective coat that replaces the epidermis in woody plants during secondary growth, formed of the cork and cork cambium. | Periderm |
| A transport system formed by xylem and phloem throughout a vascular plant. Xylem transports water and minerals; phloem transports sugars, the products of photosynthesis. | Vascular tissue system |
| Vascular plant tissue consisting of living cells arranged into elongated tubes that transport sugar and other organic nutrients throughout the plant. | Phloem |
| Vascular plant tissue consisting mainly of tubular dead cells that conduct most of the water and minerals upward from the roots to the rest of the plant. | Xylem |
| Plant tissues that are neither vascular nor dermal, fulfilling a variety of functions, such as storage, photosynthesis, and support. | Ground tissue system |
| A rigid, supportive plant cell type usually lacking a protoplast and possessing thick secondary walls strengthened by lignin at maturity. | Sclerenchyma cells |
| A continuous water-conducting micropipe found in most angiosperms and a few nonflowering vascular plants. | Vessel |
| An end wall in a sieve-tube element, which facilitates the flow of phloem sap in angiosperm sieve tubes. | Sieve plate |
| A type of growth characteristic of plants, in which the organism continues to grow as long as it lives. | Indeterminate growth |
| A cylinder of meristematic tissue in woody plants that adds layers of secondary vascular tissue called secondary xylem (wood) and secondary phloem. | Vascular cambium |
| In plant roots, the innermost layer of the cortex that surrounds the vascular cylinder. | Endodermis |
| A microscopic pore surrounded by guard cells in the epidermis of leaves and stems that allows gas exchange between the environment and the interior of the plant. | Stoma (plural, stomata) |
| The two cells that flank the stomatal pore and regulate the opening and closing of the pore. | Guard cell |
| The cellular and tissue-based processes by which an animal body takes shape. | Morphogenesis |
| A shift from one developmental phase to another. | Phase change |
| A plant homeotic gene that uses positional information to determine which emerging leaves develop into which types of floral organs. | Organ identity gene |
| A lack of symmetry; structural differences in opposite ends of an organism or structure, such as the root end and shoot end of a plant. | Polarity |
