Jade Woodcock Introduction “A Pond is commonly described by limnologists as a quiet body of water so shallow that rooted plants grow completely across it. Its water temperature is fairly uniform from the top to bottom and tends to change with air temperature. There is little wave action; and the bottom is usually covered with mud. Typically‚ plants grow all along the shore. The amount of dissolved oxygen may vary greatly in a 24 hour period.” (Pond Life 2001) There are several environmental

the xylem. The water will eventually be transported to the leaf tissue while the phloem carries nutrients from the leaf tissue to the rest of the plant. This process is able to carry out due to bulk flow which happens because of turgor pressure. Water is eventually lost by a process known as transpiration‚ where water is evaporated

Anthocerotophyta (an-tha-se-ro-TA-fa-ta) is made of three Greek roots that mean flower (anthos -άνθος); horn (keras -κέρας); and plant (phyto -φυτό). The reference is to the horn-like sporangium or fruiting body. The phylum name is formalized from a common genus‚ Anthoceros. INTRODUCTION TO THE ANTHOCEROTOPHYTA The hornworts‚ in the gametophyte stage‚ resemble the thallose hepatics; however‚ when grown in uncrowded conditions‚ the gametophytes tend to be almost circular. The thallus structure

Due to the wide range of climatic conditions‚ India holds rich variety of flora that no other country can boast of. India covers more than 45‚000 species of flora‚ out of which there are several species that are not found anywhere else. Since ancient times‚ use of plants as a source of medicines has been the inherent part of life in India. There are more than 3000 officially documented plants in India that

Diversity in Living Organisms (Science) |Close X | |[pic] Classification And Evolution Classification refers to the identification‚ naming‚ and grouping of organisms into a formal system based on similarities in their internal and external structure or evolutionary history. It determines the methods of organizing diversity of life on earth. Therefore‚ classification helps in understanding millions of life forms in detail. Who started the classification of organisms? Let us explore the history of

in these areas (Heddle 2004). The lowland mesic forest of Kauai has the largest amount of endemic plants (Sakai et al. 2002). However‚ the diet of the Green Sphinx is unknown‚ since collected moths could not be found to feed on any native plants offered to it‚ but it belongs to an herbivorous genus (Heddle et al. 2000). The life history of the Green Sphinx starts when an egg is laid onto a host plant‚ hatches into a larvae‚ then undergoes metamorphosis within a pupa to reach its adult form‚ in which

Strigolactones are compounds thought to be derived from carotenoids and are known to trigger the germination of parasitic plant seeds and stimulate symbiotic fungi. Here we present evidence that carotenoid cleavage dioxygenase 8 shoot branching mutants of pea are strigolactone deficient and

ABSTRACT An ecosystem is a very important part of our natural world. Everything relates to nature in one way or another. In turn‚ should be treated with respect and should be not tampered from its original state. With animal annihilation and extinction aside one large issue that comes to mind dealing with ecosystem imbalance is invasive species. Most invasive species do not add or diminish from there new invasive ecosystem but sometimes they can cause a devastating effect on things such as population
