Across
- 6. The apical meristem, also known as the “growing tip,” is an undifferentiated meristematic tissue found in the buds and growing tips of roots in plants. Its main function is to trigger the growth of new cells in young seedlings at the tips of roots and shoots and forming buds.
- 8. he root cap is a type of tissue at the tip of a plant root. It is also called calyptra. Root caps contain statocytes which are involved in gravity perception in plants. If the cap is carefully removed the root will grow randomly. The root cap protects the growing tip in plants.
- 9. The primary root, or radicle, is the first organ to appear when a seed germinates. It grows downward into the soil, anchoring the seedling. In gymnosperms and dicotyledons (angiosperms with two seed leaves), the radicle becomes a taproot.
- 11. A taproot refers to the presence of a large single root growing downward from the base of the plant. Taproots often have smaller hair-like roots that emerge from the central root. Some examples of plants with taproots include dandelions, carrots, parsnips, and beets.
- 12. Roots hairs are cylindrical extensions of root epidermal cells that are important for acquisition of nutrients, microbe interactions, and plant anchorage
- 13. plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support. Xylem tissue consists of a variety of specialized, water-conducting cells known as tracheary elements.
- 14. a single layer of cells that covers the leaves, flowers, roots and stems of plants. It forms a boundary between the plant and the external environment.
Down
- 1. The zone of elongation is where the newly-formed cells increase in length, thereby lengthening the root. Beginning at the first root hair is the zone of cell maturation where the root cells differentiate into specialized cell types. All three zones are in approximately the first centimeter of the root tip
- 2. plant vascular tissue that conducts foods made in the leaves during photosynthesis to all other parts of the plant. Phloem is composed of various specialized cells called sieve elements, phloem fibres, and phloem parenchyma cells.
- 3. a root (as in most grasses) that is one of many similar slender roots branching directly from the base of the stem of a plant compare taproot.
- 4. A secondary root or lateral root is a side branch of the main root, a root or a fine rootlet that derives from the primary root. Secondary roots is also used to describe an adventitious root that develops on a stem or leaves.
- 5. Plant roots have an area where freshly formed roots mature and lengthen. This region of roots is known as the region of maturation. The elongation zone is near this root area. It is a region in all plant roots where cells are created and differentiate into several cell types.
- 7. the terminal portion of a root or root branch usually including the root cap and the meristematic region behind it and often the regions of differentiation, elongation, and root hair formation.
- 10. tissue of unspecialized cells lying between the epidermis (surface cells) and the vascular, or conducting, tissues of stems and roots. Cortical cells may contain stored carbohydrates or other substances such as resins, latex, essential oils, and tannins.
