3.8.1.2 Leaf area and leaf area index (LAI) Leaf area of five randomly selected plants‚ was measured with the help of leaf area meter (Model LI-3100‚ USA) at 20‚ 40 and 60 DAS by destructive sampling from all leaves of the five sample plants (Sticker et al.‚ 1961). Plants were cut at the soil surface‚ leaves were separated from the plants‚ covered with blotting paper to keep the leaf intact and retain its original shape and were brought to the laboratory. Leaf area was measured immediately after

SPECIALIZED CELL ANIMAL Sperm cells PLANT Xylem cells are specialised to find a female cell (egg cells) and join with it. They have tails‚ that makes them move in water to find and fertilize the female cell. They can move because they have many mitochondria located between the tail and the head‚ which gives them energy. In the head‚ there is a vacuole filled with acrosome‚ which is a specialized Lysosome that releases enzymes in order for the Sperm Cell to break into the Egg Cell‚ through the

tigress weighs 117.9 kg (260 lb). The mean weight of historical Siberian tigers is supposed to be higher: 215.3 kg (475 lb) for male tigers and 137.5 kg (303 lb) for females.[7] Measurements of more than fifty captured individuals suggest that body size is similar to that of Bengal tigers.[8] The largest male‚ with largely assured references‚ measured 350 cm (140 in) "over curves"‚ equivalent to 330 cm (130 in) between pegs. The tail length in fully grown males is about 1 m (39 in). Weights of up
