Difference between secondary growth in stems and roots |
| Answer» In botany,\xa0secondary growth\xa0is the\xa0growth\xa0that results from cell division\xa0in the\xa0cambia or lateral meristems and that causes the\xa0stems and roots\xa0to thicken, while primary\xa0growth\xa0is\xa0growth\xa0that occurs as a result of cell division at the tips of\xa0stems and roots, causing them to elongate, and gives rise to primary tissue.\xa0In woody plants, primary growth is followed by secondary growth, which allows the plant stem to increase in thickness or girth. Secondary vascular tissue is added as the plant grows, as well as a cork layer. The bark of a tree extends from the vascular cambium to the epidermis. | |

What is Dorsiventral leaf? |
|
Answer» Dorsiventral leaves are found in dicots . The vertical section of a dorsiventral leaf contains three distinct parts 1 epidermis2 mesophyll 3 vascular system Dorsiventral leaves are found in dicots. The vertical section of a dorsiventral leaf contains three distinct parts.[1] Epidermis: Epidermis is present on both the upper surface (adaxial epidermis) and the lower surface (abaxial epidermis). The epidermis on the outside is covered with a thick cuticle. Abaxial epidermis bears more stomata than the adaxial epidermis.[2] Mesophyll: Mesophyll is a tissue of the leaf present between the adaxial and abaxial epidermises. It is differentiated into the palisade parenchyma (composed of tall, compactly-placed cells) and the spongy parenchyma (comprising oval or round, loosely-arranged cells with inter cellular spaces). Mesophyll contains the chloroplasts which perform the function of photosynthesis.[3] Vascular system: The vascular bundles present in leaves are conjoint and closed. They are surrounded by thick layers of bundle-sheath cells. |

What is mataxylem |
|
Answer» Make correction : it is metaxylem not mataxylem First formed xylem elements are called protoxylem , while the later formed primary xylem is called metaxylem The first formed xylem elements are called protoxylem, while the later formed primary xylem is called metaxylem.\tIn stems, the protoxylem lies towards the centre (pith) and the metaxylem lies towards the periphery of the organ, this type of primary xylem is called endarch.\tIn roots, the protoxylem lies towards periphery and metaxylem lies towards the centre, such arrangement of primary xylem is called exarch. |
