You pretty much got it.\n\nDepending on which classification system you're using a simple breakdown looks like this:\n\nDomain: Eukaryotes in this case, such as protists, fungi, animals and plants\n\nKingdon: Plante\n\nDivision: The plant kingdom is divided in to divisions (not phylums like animals) - some examples (in laymans terms):  mosses, liverworts, hornworts, ferns, cycads, gnetophytes, conifers, flowering plants \n\nClass: Two of the main groups of the flowering plants are monocots (like grasses and lilies) and dicots (like sunflowers and roses\n\nOrder: The next group. The group Magniolophyta you mentioned are here.\n\nFamily: some examples... grasses, asters, roses, buttercups\n\nGenus: examples from the Pine family (these are conifers) pine, spruce, fir, juniper\n\nSpecies: (from the spruce) blue spruce, Engalman spruce, black spruce\n\nThe genus and species are used together to form the scientific name of an organisim, e.g. Picea pungens (Blue Spruce)

Meristem\nFrom Wikipedia, the free encyclopedia\nJump to: navigation, search\n\nA meristem is a tissue in plants consisting of undifferentiated cells (meristematic cells) and found in zones of the plant where growth can take place - the roots and shoots.\n\nDifferentiated plant cells generally cannot divide or produce cells of a different type. Therefore, cell division in the meristem is required to provide new cells for expansion and differentiation of tissues and initiation of new organs, providing the basic structure of the plant body.\n\nMeristematic cells are analogous in function to stem cells in animals, are incompletely or not at all differentiated, and are capable of continued cellular division (youthful). Furthermore, the cells are small and protoplasm fills the cell completely. The vacuoles are extremely small. The cytoplasm does not contain differentiated plastids (chloroplasts or chromoplasts), although they are present in rudimentary form (proplastids). Meristematic cells are packed closely together without intercellular cavities. The cell wall is a very thin primary cell wall.\n\n                                       ***\n\nThe answer is definitely meristems. Endodermis is the outer layer of a leaf, parenchyma are the dividing cells that usually make up meristems and most soft parts of the plant, while protonema are green filaments on moss.

An embryo is a multicellular diploid eukaryote in its earliest stage of development.\n\nAt the end of the 8th week in humans, the embryonic stage is over, and the fetal stage begins.

Non-vascular, non-seed plants are called bryophtes. These include liverworts, hornwarts, and mosses. They differ from flowering plants in that they are gametophyte-oriented, or in other words they contain both male and female parts on the same plant. Also, they reproduce by spores, not seeds. The parts needed to produce such spores obviously. A flowering plant, like say a rose for instance, would only have female or male parts, but not both. Then a bee or hummingbird could tranfer the pollen from a male plant to female plant, for example.

mosses- the protenema occurs during reproduction from the sporophyte and later grows into a male or female moss gametophyte.

"Any of a division (Tracheophyta) comprising green plants (as ferns and seed plants) with a vascular system that contains tracheids or tracheary elements."  \n\nTracheid: "a long tubular cell that is peculiar to xylem, functions in conduction and support, and has tapering closed ends and thickened lignified walls."\n\nKnow any more than you did before?

1. Chloroplasts are organelles found in plant cells and eukaryotic algae that conduct photosynthesis. Chloroplasts capture light energy from the sun to produce the free energy stored in ATP and NADPH through a process called photosynthesis\n\n2. the acrosome is an organelle that develops over the anterior half of the spermatozoon's head. It is a cap-like structure derived from the Golgi apparatus. Acrosome formation is completed during testicular maturation. In Eutherian mammals the acrosome contains digestive enzymes (including hyaluronidase and acrosin).\n\n3. A centriole in biology is a barrel shaped microtubule structure found in most animal cells, and cells of fungi and algae though not frequently in plants. The walls of each centriole are usually composed of nine triplet microtubules, although Drosophila embryos have nine doublets and Caenorhabditis elegans sperm cells and early embryos have nine singlets.Centrioles are important in the cell division process, organizing the mitotic spindle upon which the chromosomes are pulled apart. \n\n4. A flagellum (plural, flagella) is a whip-like organelle that many unicellular organisms, and some multicellular ones, use to move about. They may also be involved in other processes. The name actually covers three different structures, found in each of the three domains. Bacterial flagella are helical filaments that rotate like screws. Archaeal flagella are superficially similar, but are different in many details and considered non-homologous. Eukaryotic flagella - those of animal, plant, and protist cells - are complex cellular projections that lash back and forth. Sometimes the last are called cilia or undulipodia to emphasize their distinctiveness.\n\n5. The endoplasmic reticulum or ER (endoplasmic means "within the cytoplasm," reticulum means "little net") is an organelle found in all eukaryotic cells. It is part of the endomembrane system. The ER modifies proteins, makes macromolecules, and transfers substances throughout the cell. Prokaryotic organisms do not have membranous organelles and thus do not have an ER. The basic structure and composition of the ER is similar to the plasma membrane, although it is actually an extension of the nuclear membrane. The ER is the site of the translation, folding, and transport of proteins that are to become part of the cell membrane (e.g., transmembrane receptors and other integral membrane proteins) as well as proteins that are to be secreted or "exocytosed" from the cell (e.g., digestive enzymes).\n\n6. Glyoxysomes are membrane-bound organelles found in plants, particularly in the fat storage tissues of germinating seeds. Glyoxysomes contain enzymes that initiate the breakdown and conversion of fatty acids to sugars, which the emerging seedling uses as an energy and carbon source until it is able to produce its own sugar by photosynthesis. In this pathway, fatty acids are hydroylzed to acetyl-CoA for the glyoxylate bypass\n\nthere are so many more organelles........

Here's what I learned:\n\nBoth gymnosperms and angiosperms have vascular tissue and both produce seeds. However, the seeds of angiosperms are surrounded by the wall of the ovary of the flower which forms the fruit, whereas gymnosperms do not possess this structure. Their seeds are described as naked (Gymnosperm from the Greek: gymnos - naked, sperm - seed). Botanists place the angiosperms in the group (division) Angiophyta but the Gymnosperms do not form a coherent group and are separated into four divisions.\n(from http://www.botany.uwc.ac.za/ecotree/gymangio.htm)\n\nI don't really see the wall of the ovary as one of the choices you offer.  I guess the answer is C--fruits.

id say the plants and animals are multi-celled and the others are single-celled. also cell specilization could be a difference.

1. Kingdom Monera [10,000 species]: Unicellular and colonial--including the true bacteria (eubacteria) and cyanobacteria (blue-green algae).\n\n2. Kingdom Protista (Protoctista) [250,000 species]: Unicellular protozoans and unicellular & multicellular (macroscopic) algae with 9 + 2 cilia and flagella (called undulipodia).\n\n3. Kingdom Fungi [100,000 species]: Haploid and dikaryotic (binucleate) cells, multicellular, generally heterotrophic, without cilia and eukaryotic (9 + 2) flagella (undulipodia).\n\n4. Kingdom Plantae [250,000 species]: Haplo-diploid life cycles, mostly autotrophic, retaining embryo within female sex organ on parent plant.\n\n5. Kingdom Animalia [1,000,000 species]: Multicellular animals, without cell walls and without photosynthetic pigments, forming diploid blastula.\n\n\nSo far those are the five Kingdoms I know of if there are a few more I have no idea but it is possible. Or you are confusing with bilogical organizations, which are 7

It's a type of green algae.  So, it's part of the kingdom Plantae and the phylum Chlorophyta.

its a member of the kingdom Protista, which includes eukaryotic, mostly unicellular organisms with animal-like (protozoa), plantlike (algae), or funguslike (slime moilds) modes of nutrition. I take microbiology in collage if u need more info email at Njacobs7477@yahoo.com

An angiosperm is a flowering plant such as a rose or a maple tree. They are not to be confused with gymnosperms the other type of flowering plant. Angiosperms are seed-bearing plants. They are in the Magnoliophyta division. They are divided into monocots and dicots. Cell walls are present in plant and animal cells but fungi cells have some sort of surrounding over them. Whether it's an angiosperm, gymnosperm, fern, or anything else a plant cell will have a cell wall. I thought you just had no idea what an angiosperm even was when you asked the question or you might not have asked it if you did.
