Domains & kingdoms

Kingdom Plantae Kingdom Plantae is multi-cellular, autotrophic, non-motile, has eukaryotic cells, has asexual and sexual reproduction, and is mostly found on land. An example would be a flower.Kingdom Anamalia Kingdom Anamalia is multi-cellular, heterotropohic, motile, has eukaryotic cells and the largest group is arthropods. An example would be a bearKingdom Protista Kingdom Protista has eukaryotic cells, motile, colonial, autotrophic & heterotrophic, and has asexual reproduction. An example would be algae. Kingdom Fungi Kingdom Fungi has eukaryotic cells, uni colonial, non-motile, has asexual reproduction and forms spores. An example would be a mushroom.Domain BacteriaAlso known as eubacteria, is prokaryotic, aerobes, cell wall which contains peptidoglycan, microscopic, lives in moderate environments, and DNA is unique to eubacteria. Domain Eukarya (Huge Domain) everything contaning ekaryotic cells, the 7 levels of classification. Composed of fungi, protists, plants and animals.Domain ArchaeaHas harsh living environments, microscopic, has cell walls but no peptidoglycan, meant to live in harsh conditions like the Hot Springs.

Algae

There are 3 types of AlgaeBrown Algae: Brown algae is in the Protista Kingdom, and is in the phylum heterokontophyta. Brown algae is commonly found in the marine temperate. An example of would be kelpRed algae: Red algae is in the Protista Kingdom, and the phylum is Phodophyta. Red algae is held in a warmer tropical waters, in temperate zones found in deeper water. An example of Red algae is a Turkish Wash Cloth. Green Algae: Green algae is as well in the Protista Kingdom, with the Phylum Chlorophyta. This algae is a very diverse group. An example would be Sea lettuce.We believe land plants are developed from Algae because Multicellular Green Algae are ancestors of land plants, even though they're mostly marine.

Bryophytes

Bryophytes are composed of mosses, liverworts and hornworts. Bryophytes protect the embryo and have thin waxy cuticles utilizing the air for species distribution. This life cycle to the left represent the typical life cycle of bryophytes and the steps. The bryophyte spore germinates into producing the protonema by releasing the spores from the operculum, making rhizoids. After leads to the gametophytes, make a female and male gametophytes until they mature. Undergoing Mitosis, the antheridium (male reproductive system) makes sperm and the archegonium (female reproductive system) makes an egg and sends it to the embryo taking part in now fertilization.

Lifestyle of a pteridophyte

The pteridophytes are another name for a fern. The life cycle of fern is roughly the same as a bryophyte. Starting at Meiosis the spores germinate continuing to make gametophytes producing the sperm and egg for archegonium and antheridium, undergoing fertilization. After fertilization of the two gametophytes, sporophytes take place going into the roots of Fronds making Rhizoids. The spores that are now germinated are travelling into the Indusim of the Sorus. The cycle is now finished and undergoes repeating Meiosis again.

Examples of pteridophytes

Some examples of a pteridophyte:Horsetail: are a class in the Pteridophyta (ferns). They were one of the most important plant groups in the Palaeozoic era. The group is now almost extinct, but one genus survives. They are vascular plants that reproduce by spores and not by seeds. Selaginella: Selaginella is a genus of plants in the family Selaginellaceae the spikemosses, Selaginella species are creeping or ascendant plants with simple, scale-like leaves (microphylls) on branching stems from which roots also arise.Psilotum: is a genus of fern-like vascular plants, one of two genera in the family Psilotaceae, order Psilotales, and class Psiltosida.

scompare & Contrast - Bryophytes and pteridophytes

Contrast Bryophytes are non-vascular; Pteridophytes are vascular Bryophytea are first land plants; Pteridophytes are first land plantsBryophytes are mosses;Pteridophytes are fernsBryophytes are not water transporting systems;Pteridophytes are "Transport tubes" of plants

Compare Both have many examplesBoth have similar lifecycles Sperm must swim in both lifcyclesBoth haploid cells sprout to grow a Gamtophyte
