|
Answer» erial which do not require for normal GROWTH and development are Secondary metabolites.Alkaloids, Tanins, Resins, Gums, and Latex are some of the secondary metabolites in PLANTS.Alkaloids :- These are nitrogenous by-products and are poisonous.These are stored in different PARTS of the plants.Common alkaloids in plants are nimbin, quinine, caffeine, etc.TANNINS :-Tannins are carbon compounds. These are stored in different parts of the plant and are deep brown in colour.Tannins are used in tanning of leather and in medicines E.g. Cassia, Acacia.Resin :-These occur mostly in Gymnosperms in specialized passages called resin passages. These are used in varnishes. E.g. Pinus.Gums :-Plants like Neem, Acacia secretes a sticky substance called gum when branches are cut.The gum swells by absorbing water and helps in the healing of damaged parts of a plant. Economically, gums are being used as adhesives and binding agents in preparation of the medicines, food, etc.Latex :-Latex is a sticky, milky white substance secreted by plants. Latex is stored in latex cells or latex vessels. From the latex of Hevea braziliensis (Rubber Plant) rubber is PREPARED. Latex from jatropa is the source of biodiesel. |

Suggest an experiment to study geotropism and phototropism |
|
Answer» If you were to put a plant on its side, you'd notice that, after awhile, the roots would start growing downward while the stem would grow upward. This response to gravity is CALLED geotropism, or gravitropism. The roots are exhibiting positive geotropism, or growth with gravity, while the stem is exhibiting negative geotropism, or growth against gravity. Different parts of a plant grow in opposite directions because they have different functions. The roots need to grow into the ground to provide stability for the plant, as well as to access WATER and nutrients. The stem needs to grow upward toward the sunlight so the plant can photosynthesize, or make food from sunlight. So, how do different parts of a plant KNOW which way to grow? Plants have organelles called statoliths, which settle at the bottom part of their cells and allow plants to sense gravity. They also have a HORMONE called auxin, which stimulates elongation and growth in plant cells. For root cells, the statoliths and auxin trigger downward growth, while cells above ground are signaled to grow upward.Explanation: |

To produce 60 seeds how many reduction divisions are required |
|
Answer» One egg is produced by the meiosis of egg mother cell. So, the total number of seeds is EQUAL to the number of meiotic divisions in the female. It is also KNOWN that each pollen mother cells divide by meiosis to form four haploid pollen grains. Out of which, only one pollen GRAIN participates in fertilisation. Therefore, 1/4 of the total number of seeds is equal to the number of meiotic divisions in a MALE. Now, total number of divisions = (50/4)+50 = 12.5 + 50 = 62.5. The divisions can not OCCUR in decimals. So, the correct option is option D. |
