Can You Answer The Following Botany Terms Quiz

Root hairs originate from the epidermis layer of plant roots, which is the outermost layer responsible for absorption of water and nutrients.

Lateral roots originate from the pericycle, which is a type of parenchyma tissue located in the roots. The pericycle is responsible for lateral root formation and branching.

The correct answer, granules in cortex cells, is evidence of the food-storage function in buttercup roots as these granules store food reserves for the plant. The incorrect answers do not align with the specific evidence of food storage in cortex cells.

The endodermis is the innermost layer of the cortex in a dicot root, and it surrounds and borders the stele.

The stele in plants is the central cylinder of vascular tissues that includes the pericycle, phloem, and xylem. The incorrect answers provided do not accurately describe the components of the stele.

The vascular cambium is a plant tissue responsible for producing the secondary xylem and phloem, which are essential components for plant growth and transport of water and nutrients.

A pith is not present in all roots. It is a central core of tissue found in the stems of certain vascular plants, but not typically in roots.

In monocot roots, the pith is present at the center of the root structure. Dicot roots do not have a pith, while fibrous roots have a fibrous structure without distinct pith. Taproots have a central core but it is not technically considered a pith.

Lateral roots develop by growing through specific tissues within the primary root to reach the surface for nutrient and water absorption. The correct answer includes the endodermis, cortex, and epidermis as these are the layers typically penetrated by developing lateral roots.

The vascular cambium is a meristematic tissue found between the primary xylem and primary phloem in dicotyledonous plants, responsible for secondary growth and formation of vascular tissues.

In dicot roots, the pith tissue is not present, while xylem, phloem, and cortex are commonly found in both stems and roots.

Root hairs are typically found in the epidermal tissue of plant roots, where they absorb water and nutrients from the soil. The other tissue options provided, including cortical, phloem, and xylem, do not contain root hairs.

The pericycle is the tissue that surrounds the vascular tissue and is located adjacent to the endodermis on the side toward the center of the plant root.

The correct region where differentiation of cells into various cell types takes place in the root is the zone of maturation where the fully developed cells are found. The other options represent different stages of cell growth and function in the root.

Cells in the cortex containing granules suggest that they are involved in storing food, as granules are commonly associated with storing molecules such as starch or lipids for energy reserves.

Casparian strips are composed of suberin, a waxy substance found in the cell walls of endodermis cells in plant roots. Cutin is a waxy substance found in the cuticle of leaves, wax is a generic term for a variety of lipid substances, and chlorophyll is a green pigment involved in photosynthesis.

Vascular cambium is the tissue responsible for secondary growth in plants, specifically adding to the girth of the root. The epidermis is the outermost layer of cells in plants, while xylem and phloem are responsible for transporting water and nutrients throughout the plant.

The primary xylem is the water-conducting tissue that is present in the center of a dicot root, responsible for transporting water and minerals absorbed by the roots upwards towards the leaves. Phloem is responsible for transporting sugars produced during photosynthesis. The cortex is the region of a root that surrounds the vascular cylinder. Secondary xylem is formed as a part of the secondary growth process in plants.

Terminal bud scales are specialized protective structures that cover and shield the buds of dormant twigs during the winter months. These scales help prevent damage to the delicate tissues within the buds.

Axillary buds are located in the angle between the stem and the petiole of the leaf, where they can develop into branches or flowers.

Lenticles are small openings in the bark of woody plants that allow for gas exchange between the internal tissues and the external environment. Stomata are found on the surface of leaves, guard cells regulate the opening and closing of stomata, and xylem vessels transport water and nutrients in plants.

The vascular cambium, xylem, and phloem are responsible for separating cortex from pith in an older alfalfa stem. The function of this tissue is primarily for storage purposes.

The cortex and pith of a plant primarily serve the purpose of storing and manufacturing food through various metabolic processes. These tissues are responsible for the storage of nutrients and synthesizing sugars and other essential compounds for the plant's growth and development.

Xylem is the plant tissue responsible for transporting water and minerals from the roots to the rest of the plant. Phloem, epidermis, and cortex do not perform this function.

When comparing cross sections of plant stems, the key differences to observe are the arrangement of vascular bundles and the presence of pith. These characteristics are important for identifying the plant species by their stem structures.

Gentian violet and eosin are commonly used stains in histology to differentiate between different tissues and make them more visible under a microscope. Methylene blue and safranin, hematoxylin and crystal violet, and acid fuchsin and methylene green are not commonly used for this purpose.

Xylene helps dissolve any remaining water in the wood and balsam provides a protective coating to make the slide permanent.
