BIO100A Home 2 - Lab Report ExampleThe pine cone protects the seeds from the irrigate logging by covering them with the woody scales. The seed cone was kept in a cup of water supply and the change in the cone appearance was observed.d) Record time reveal of water 5 minutes. The seed cone appearance more swollen and the woody scales of the cone argon soft and comes out easily when touched up. The color of the seed cone has changed. Since the scales atomic number 18 soft, the seeds are now getting exposed. there are small pores visible to the naked eye in the cross section of the celery stalk. They are juicy and filled with water. This concludes that there are xylem tubes present in the stalk to carry plentiful water within it.Seed dissemination is very important for the plants for many reasons. The most important thing is that they change the seeds to grow in a habitat that is away from the parent plant and they increase the survival vagabond of the seeds. The seeds are disper sed to different environmental conditions and the plant variety is dispersed to different regions. The survival measure of the seed increase as they receive food with less competition. The seeds also get the chance to estate on the soil for better growth. (Lawson, 2001).Gymnosperms engage wind, water and rain, animals to disperse the seeds. Some gymnosperms such as cherry wood require fire to release the seeds. Fire is used by a means by the redwood to ensure nutrient for the seedlings and less competition from the environment for the growth of the seed. The gymnosperms have wings for the dispersal of the seeds. The nuts in the pine are spread by the nut-eating animals too. Angiosperms are more diverse in their types and population. The seeds of angiosperms are very light and have fluffy wind spread seeds or winger seeds. Some angiosperms use sea route, flooding forests, large animals and wind.Redwoods release the seed only after a fire. The female cones are tightly packed and p reserved as such for
