El_Hotsausage Posted June 14, 2004 Share Posted June 14, 2004 Can anyone describe which types of reproduction (sexual, asexual)(binary fission, budding, cloning etc) would be the best for both a plant and an animal in the following conditions: Desert Jungle Arctic Deep Ocean Grassland / Savannah I have used google buth I can't seem to find anything so, if you have any information I would grately appreciate it. Thank you. Link to comment Share on other sites More sharing options...
Deryck Posted June 14, 2004 Share Posted June 14, 2004 I think it is really up to the type of organism though. I might be wrong though, sorry. Link to comment Share on other sites More sharing options...
syphern Posted June 14, 2004 Share Posted June 14, 2004 Well I would say its common sense: (Binary fission is mitosis right?) it also depends on how much energy is used. Desert: Due to harsh conditions many plants cannot grow so asexual reproduction would be best. And budding. Animals well I would say sexual due to harsh conditions again and they need to evolve from the fittest, and in these conditions only the fittest survive. Jungle: Well i would say normal conditions for this one. Arctic: hmm not sure but for small microorganisms I would definately say mitosis. But for plants cross pollination would not be an option. And since I have never seen too many plants in the Arctic i would say asexual. Animals, well normal sexual reproduction. Deep Ocean: Im not too sure on this one, you can work it out hopefully, think about the factors low levels of oxygen thus low amounts of ATP produced... which reproduction uses the most amount of energy? Grassland / Savannah: Definately cross pollination for plants! And again for animals i would say sexual. BTW you should check your biology syllabus for clues sometimes they give examples.

monkey55 Posted June 14, 2004 Share Posted June 14, 2004 Typically i'd say google it, but keep search phrases simple like "deep ocaen reproduction", ill give ya a hand though and give you some links that i found on google, they give reasons for why reproduction may occur in a specific way, though it is implied rather than stated as a fact, ie low oxygen/high pressure wouldnt favor normal reproduction (sexual reproduction). Desert: http://www.western.edu/faculty/jsowell/des...cology/ch6.html Jungle: Id say normal, sexual reproduction as temp, nutrients, prey etc. are all abundant. Only factor for plants would be lack of sunlight in dense jungles. Couldnt find aspecific link for this. Arctic: http://biologi.uio.no/fellesavdelinger/fin...iles/repro1.htm Deep Ocean: http://www.pulseplanet.com/archive/Jun04/3212.html Grassland / Savannah: Sexual for animals (think lions/big cats etc. giraffes monkeys...) plants same.

syphern Posted June 15, 2004 Share Posted June 15, 2004 It isn't mitosis. Simple cell division - binary fission When a cell divides by binary fission, it basically splits into two. It is a form of reproduction which produces two new cells that are usually exact copies of the original cell. Just before the cell splits, it makes an extra copy of its DNA and the two copies are moved to opposite ends of the cell. The cell then contracts in the middle, so that each of the new cells, gets a complete copy of the original DNA. This isn't mitosis? :blink: Link to comment Share on other sites More sharing options...

IN the matching section there were 15 answers to match with 15 letters. C was Mitosis and H was Binary Fission. They both had separate, different answers. Thus, they are not the same.

syphern Posted June 15, 2004 Share Posted June 15, 2004 I have never heard of Binary Fission, maybe once where the teacher dismissed it as mitosis, so thats where i got the idea. EDIT: aaah! I got it by googling it, mitosis = in eukaryotes and binary fission = in prokaryotes. But both processes are the same. Link to comment Share on other sites More sharing options...
username Posted June 15, 2004 Share Posted June 15, 2004 Generally speaking, in harsh conditions, where there are low populations of plants and animals, and the climate experiences only rare times for ideal mating conditions, asexual animals and budding in plants is beneficial, it allows for reproduction but obviously not the exchange of genes i have a degree in biology btw Link to comment Share on other sites More sharing options...
