Which dichotomous pair of alternatives is highlighted by the life cycle of the cellular slime molds?

Taking a stab at it...I think it's C.  \n\nFrom what I can remember, during the life cycle of a slime mold, it begins as a large unicellular organism that eventually aggregates with surrounding cells to produce smaller individual organisms that are a part of a larger multicellular organism.

Protists:  CLICK LINK BELOW FOR NAMES AND PICTURES ! YOU SHOULD BE ABLE TO PRINT THAT PAGE.\n\nSlime molds and algae are protists.\nSometimes they are called the odds and ends kingdom because its members are so different from one another.  Protists include all microscopic organisms that are not bacteria, not animals, not plants and not fungi.\nMost protists are unicellular. You may be wondering why those protists are not classified in the Archaebacteria or Eubacteria kingdoms.\nIt is because, unlike bacteria, protists are complex cells. \n \nThese delicate looking diatoms are classified in the protist kingdom. (Click link below for names and pictures.)

1)  The cell is the unit of structure, physiology, and organization in living things. \n   2)  The cell retains a dual existence as a distinct entity and a building block in the   construction of organisms. \n   3)  Cells form by free-cell formation, similar to the formation of crystals (spontaneous generation).\n\nKeep this as hint and do your homework

In general, organisms with less complexity, are less likely to have homeoboxes\n\nHomeoboxes seem to be reserved for higher eukaryotic cells (like human cells) that require specialized cells which will coordinate complex tasks in conjunction with other specialized cells (at least that's my simplistic viewpoint).\n\nE.coli, for example, does not contain homeoboxes because it is not dependent so much on its sister cells. \n\nI had fun thinking about the answer to your question.  Don't forget to pass on the good karma.

Haploid\nHaploid cells bear one copy of each chromosome.\n\nMost fungi, and a few algae exist as haploid organisms. Male bees, wasps and ants are also haploid. For organisms that only ever have one set of chromosomes, the term monoploid can be used interchangeably with haploid.\n\nPlants and other algae switch between a haploid and a diploid or polyploid state, with one of the stages emphasized over the other. This is called alternation of generations. Most diploid organisms produce haploid sex cells that can combine to form a diploid zygote, for example animals are primarily diploid but produce haploid gametes. During meiosis, germ cell precursors have their number of chromosomes halved by randomly "choosing" one homologue, resulting in haploid germ cells (sperm and ovum).\n\n\nDiploid\nDiploid cells have two copies (homologs) of each chromosome (both sex- and non-sex determining chromosomes), usually one from the mother and one from the father. Most somatic cells (body cells) of complex organisms are diploid

Amoeba are single celled organisms.  They are found in a variety of places and serve a variety of purposes.

Euglena can divide into two separate organisms by splitting down the middle. This is called Binary Fission. Binary fission usually begins with the on set of night fall with the large flagellum being shed first. The nucleus, chloroplast and basal bodies all divide so each new cell ends up with the required cell components. This procedure takes quite a long time and requires plenty of spare time to follow all the way through.\n\nThey can also exchange genetic material using conjugation. This is a form of sexual reproduction.

I would do something like this:\n\n* Similarities and differences among living organisms\n(For example, the characteristics of life, cells, comparing single and multicellular organisms)\n*Homeostasis in living things\n(Basic biochemical processes, Feedback systems, Disease)\n*Genetics\n(Heredity, Genes)\n*Reproduction and development\n(Cell division, reproduction among organisms)\n*Evolution\n(Theories)\n*Ecology\n(Interaction between organisms and their environments, energy flow)\n\nThese are just a few ideas.

mitosis is asexual reproduction, cells divide and reproduce replicating their own DNA exactly\n\nmeiosis is sexual reproduction, new cells contain only half of their original DNA, and half from a different parent source

Richard Dawkins has two wonderful chapters on cnidarians (jellyfish) and poriferans (sponges) in 'The Ancestor's Tale.'\n\nCnidarians have two body plans, the medusa (jellyfish) and the polyp (sea anemones and hydras).  Polyps often reproduce by budding and can make huge colonies of organisms.  The portuguese-man-of-war is actually a complex colony of medusa and polyp forms.  (BTW, he has a great discussion about how the stinger cell in jellyfish may be the most complex structure in any cell anywhere in the animal and plant kingdoms. Way cool!)\n\nPoriferans (sponges) are even simpler organisms.  Although they are ostensibly multicellular organisms, with several types of cells, these cells don't organize themselves into specialized tissues and organs. Sponges are able to reproduce both asexually and sexually.\n\nSo the evolutionary significance is that an individual is basically a colony.  As such they are right at the boundary between single-celled and multi-celled creatures.  They demonstrate how multi-celled organisms could arise as a colony of cooperating single-cells.

interphase: the nucleolus is visible, cell engaged in metabollic activity, ceirtainly a pair of centrioles.

Varied like any one cell organism. Amoeba are in this class. They process varied organic matter so they serve a recycling function. More info at the links given.

This is when a cell reproduces by either mitosis (in most cases) or meiosis (in the case of sex cells)\n\nSee http://www.scienceaid.co.uk/celldivision.html for more information

Sponges are able to reproduce sexually or asexually. Most sponges are monoecious. Sperm are formed from choanocytes; and oocytes derive from choanocytes in some sponges, and archaeocytes in others. Sperm are released into open water. Some sponges have oviparous fertilization where sperm and eggs meet in open water. In other species sperm are taken into the bodies of other sponges and fertilized inside; this is known as viviparous fertilization. The free-swimming larvae, known as parenchymula, serve as one of the main forms of dispersal for this largely sessile phylum. Asexual reproduction of sponges is through budding, where a small piece of sponge falls off of the main sponge and grows into a new one. Many freshwater sponges form small structures known as gemmules, which function as overwintering devices. These are similar to a bacterium's endospore. Gemmules are made up of amoebocytes surrounded by a layer of spicules and can survive conditions that would kill adult sponges. When the environment becomes less hostile, the gemmule resumes growing.

CYTOPLASM... i wish i could live in some cytoplasm, that would be so much fun!

The kingdom Protista consists of all the organisms that do not fit into any other kingdom.  This kingdom is simply for the misfits that still fit some of the requirements.  Slime Mold contains properties of several other kingdoms, like most members of the Protista kingdom, but do not soley fit into any other kingdom, making it only suitable to be classified as a protist.

Amoeba s the correct answer.
