How polyembryony can be commercially exploited |
|
Answer» (1) Polyembryony is the development of more than one embryo inside the SEED.(2) When such polyembryonic seed germinate We get muldple seedlings from it.(3) This condition increases the chances of survival of new plants.(4) NUCELLAR EMBRYOS are genetically identical to parent plants hence we get uniform plants.(5) In horticulture we can utilize these as rootstock for GRAFTING hence they have significant role in iruft breeding programmes e-g Citrus, Mango.see more :How polyembryony can be commercially EXPLOITED brainly.in/question/1192658 |

1.What happens to the cells formed by meristematic tissue? 2.Where is apical meristem found? 3. Describe the characteristics of meristematic tissue? 4.Where is lateral meristem found and what function does it perform? 5. State the functions of meristematic tissues? 6. Where is intercalary meristem found and what function does it perform? |
|
Answer» 1 - The cells formed by meristematic tissue take up a specific role and lose their ability to divide. As a result, they form a permanent tissue. This process of taking up a permanent shape, SIZE and function is called differentiation.2 - APICAL meristem is found at the apices, or tips of the plant, both the tip of the shoot and the root, and is a region of actively dividing cells. 3 - Meristematic tissue has a number of defining features, including small cells, thin cell walls, large cell nuclei, absent or small vacuoles, and no intercellular spaces. The apical meristem (the growing tip) functions to trigger the GROWTH of new cells in young seedlings at the tips of roots and shoots and forming buds.4 - Secondary, or LATERAL, meristems, which are found in all woody plants and in some herbaceous ones, consist of the vascular cambium and the cork cambium.5 - Primary meristematic tissue helps the plant increase in length or vertical growth, meaning it helps the plant grow up toward the sun and down into the soil. Secondary meristematic tissue helps the plant increase the girth or lateral growth of its stems, branches, and roots.6 - Intercalary meristem is located at internodes or stem regions between the places at which leaves attach, and at leaf bases, especially of certain monocotyledons. The cells of the intercalary mersitem are active and CONTINUOUSLY form a number of new cells. |

Why only some plants have nectaries |
