Answers:well honey..the answer for the prokaryotae or monera is a unicellular spcs dat do not hv nuclear mmbrn wit simple orgnstn without muscle n no tssue form such as bacteria..for protista most of organsm is unicellur sch as protozoa n algae..for fungi it is common for saprophytic organism sch as mushroom..for plantae is a multicell orgnsm dat able to produce its own food sch as cactus plant..and the animalia is also multicell orgnsm whch usually holozoic sch as dolphin..
Answers:Archaebacteria-unknown live in harsh conditions Eubacteria- blue-green algae, in the ocean Protista-paramecium Fungii-Mushrooms, ground Plantae-trees Animalia-human
Answers:Bryophyta life cycle is dominated by the gametophyte all others show decreased gametophyte and dominant sporophyte. Sphagnum are one class of mosses. Sphagnum novo-caledoniae in endemic to New Caledonia. These plants have no internal water transport vesicles. They are dependent on osmosis to move water to internal cells so all parts must be near water. That is the environment controls the mosses state of hydration they cannot control it internally. Bryophytes and Pteridophytes plus Ginkgo biloba and the cycads have flagellated sperm. Sperm from ferns and lycophytes (club moss) are multi-flagellated (carrying more than one flagellum). In seedless vascular plants, cycads and ginkgo, sperm are huge complex cells with multiple flagella. Water is still required for these sperm to swim to the archegonium containing the egg. Pterophyta have & megaphyll leaves with true veins. These plants move water in conducting/strengthening tissue so they have an upright, somewhat larger form. Roots and vesicles to move water internally mean they are less dependent on water being in contact with all parts. Ferns have no pollen/seeds, these plants have spores & gametes that must swim in water. The male gametophyte produces gametes that swim in water, to a female gamete (usually part of the same small thallus or gametophyte). Sporophyte is dominant life cycle. Gymnosperm have simple branching architecture with lateral meristem producing the vesicle tissue. Compression wood in the branch collar resists the branch bending down under its own weight and forms beneath the branches. Compression wood evolved in the Ginkgoales, & Coniferales 300 million years ago. It is not found in the cycads. This group have single sexed cones bearing pollen or seeds. The plants we see as trees are the sporophytes but they do not release spores. Instead they release pollen, the whole male gametophyte, to find the female gametophyte, still in a cone. The seed is fertilized before being released so the big change is being 2n and able to travel as a miniature dormant sporophyte. Two stages of travel for great cross fertilization and even better range for the offspring's spread. Cycadophyta have relatively little conducting tissue so have slow growth rates. . Pinnate, compound leaves have a central rachis (mid support) and the leaves grow in a spiral from a apical growth point. Plants bear one sex of cones. Cycads survive to this day as tropical plants, with some 200 species, much as they were in the carboniferous era. Cycas revoluta is the sago cycad of Japan. http://plantnet.rbgsyd.nsw.gov.au/PlantNet/cycad/cycintro.html http://www.colby.edu/~ragastal/Paleobotany/mesogymnosperms.htm Gingophyta exist today with the single species Ginkgo biloba. These have deciduous leaves with veins but not true secondary netted veins because but they show dead ends in the veins. They also have cones. http://www.xs4all.nl/~kwanten/ Coniferophyta is the largest taxon in the gymnosperm. Conifers are the gymnosperm with needle-like or scaled leaves that grow male and female cones as reproductive organs. Male pollen cones release pollen that blows in wind from tree to tree, having very little insect pollination. The female cone has scales, spiraling around a central axis, that each shelter an integument covered ovule. Cones have no enclosed ovary hence the name gymno meaning naked or bare. The scale covers the ovule until the seed is mature than the scale opens leaving an exposed seed. Conifer seeds have no triploid endosperm. Endosperm for the embryo is haploid, grown from the female parent gametophyte before fertilization of the ovule. The plants keep the sexes separate. Some conifers bear both male and female cones while some bear only male or only female cones. Cotyledons (2- 24 seed leaves depending on species) emerge as a whirl around the embryonic stem like ribs of an umbrella from the handle. Branches grow spiraled around around the trunk with apical growth so they end with a conical from. Taxodium distichum is bald cypress from the southern USA. Anthophyta are flowering plant classes with enclosed ovaries. These plants have widely diverse forms from small herbs to large trees and vines. Pollination symbioses with insects has coevolved elaborate specialized floral strategies in ~80% of flowering plants. Fruit form is usually specialized to help disperse seed: allochory by animals, wind, water, or by autochoric mechanical methods. Angiosperm trees have reaction or tension wood that forms on the upper side and holds the branch angled out from the trunk. The branching is less regular and more responsive to environmental conditions so the tree can grow to reduce self-shading and maximize leaf exposure. Rosa cinnamomea is the cinamon rose from Siberia and northern Europe.
