 Sodium Chloride (NaCl) solution  were   created   and  the  effects  that  they  had  on  radish   seeds  were  tested.  This  ultimately  created  a  dose­response  experiment  in  which  it  was  detectable whether  or  not  radish  seeds  were  a  reliable  bioassay  for  the   toxicity  of  NaCl.  The  goal  of  this  experiment  was  to  determine  a  correlation  between  toxicity  and  seed  germination/radicle  length.  Our  data  indicated  that  seed  germination  decreased  as  concentration  increased,  demonstrated ...

Cotton

staple fiber that grown in a form known as a boll around the seeds of the cotton plant, a shrub native to tropical and subtropical regions. Cotton fibers are mainly made up of cellulose. Under natural conditions, the cotton bolls will tend to increase the dispersion of the seeds. The cotton fibers are attached to the seeds inside the boll of the plant. There are usually six or seven seeds in a boll and up to 20,000 fibers attached to each seed. The fiber is most often spun into yarn or thread and used...

Testing the Effects of Radiation on Plants

Abstract The purpose of this lab was to see if radiation has an effect on the cultivated radish seeds that we used. From the observed data that we collected, we were able to conclude that when seeds are exposed to radiation, it affects how they grow, if there is any growth at all. Introduction Radiation is an important environmental abiotic factor for plants, and one small section of the electromagnetic radiation spectrum, is called the Photosynthetically Active Radiation (PAR), provides...

Conclusion

include in phylum Anthophyta.Angiosperms are plant that have flowers and fruit. Their part of the flower is a carpel which surrounds and protects the ovules and seeds. The fruit surrounds the embryo and aids seed dispersal. The great majority of angiosperms are classified either as monocots or eudicots.Monocot embryos have a single seed leaf (cotyledon), and pollen grains with a single groove while eudicots (true dicots) have two cotyledons, and pollen grains with three groove. Monocotyledons have...

Gymnosperms

Greek words that mean "naked-seeded," in reference to the fact that gymnosperm seeds are produced out in the open on cone scales, while the seeds of flowering plants are produced completely enclosed within fruits. In the previous lab we learnt that bryophytes and Pteridophytes of the kingdom Plantae, reproduce by spores. In gymnosperms and angiosperms (flowerng plants), however, dispersal is primarily by means of seeds, which are considerably more complex and larger than spores. In contrast to the...

Initial Set-Up of a Model of the Mass Flow Hypothesis for Translocation

explain why animal cells store glycogen instead of simple sugars. (5 marks) (c) Round seeds and wrinkled seeds are two phenotypes of garden pea. The wrinkled phenotype is attributed to the absence of a starch-forming enzyme in the seeds. In terms of water relations, explain why the lack of the starch-forming enzyme will lead to the wrinkled appearance of the garden pea seeds at maturity. (HINT: Garden pea seeds become dehydrated at maturity.) (4 marks)(Total: 20 marks) | 2. (a) (i) ● the...

Coconut Tree

regions and Africa. In later years, sailors and explorers spread the growth of coconuts even farther by taking the seed (yes, it is a seed – not a fruit or a nut) with them for food. The sailors aboard Vasco de Gama’s ships gave the coconut its name.  They called it “Coco”, named after a grimacing face or hobgoblin.  The brown, hairy husk and three face-like dimples made them think the seed looked like a sort of spirit.  When the “coco” came to England, the suffix of nut was added and that’s how the...
