Science....forgot binder help with plants and cells?

Question

1) How were Aristrotle and Carolus Linnaeus involed in the classification of living organisms?
2) What are the main parts of a flower and what are their purposes
3) Animal, Plant and Fungus, list one characistic for each ( ex. Archaebacteria- bacteria with no nucleus)



Try to answer as many as u can i forgot my science binder and i cant find it in the book thanx for any help!

Answer 1

1. Aristotle created one of the first taxonomical systems. Unfortunately, this system was very complex and forced people to remember extremely long plant names. Carl Linnaeus simplified this by creating a binomial system that identified a plant by combining its genus name and specific epithet. i.e the canadian hemlock would be Tsuga canadensis.

2. Petals: Collectively called the corolla, petals attract pollinators to the flower

Sepals: Collectively called the calyx, sepals rest under the petals. The sepals usually have no distinct purpose, though they are sometimes modified into petal-like structures.

Stamen: Composed of the filament and the anther. The cells of the anther go through meiosis in order to produce spores, which in turn become pollen cells, the male gamete of the flower.

Pistil: Composed of the style and stigma, pollen cells land on the stigma, and the pollen tube grows down the style to the ovaries. The sperm in the pollen cells swim down this tube in order to reach the eggs in the ovary.

Ovary: Houses the female gametophyte, which produces eggs.

Peduncle: The structure that the flower grows on. Analagous to a stem.

3. I'll give you a good list

Kingdom: Fungi (Heterotrophic, absorbs food through hyphae)
Division: Chytridiomycota (Mostly aquatic, has flagellated spores)
Division: Zygomycota (Also called black bread molds, produces sporangia through a zygospore)
Division: Ascomycota (Has a dikaryon stage in the life cycle. Creates 8 ascospores in asci. Also called sac or cup fungi)
Division: Basidiomycota (Club fungi, they create four basidiospores in a basidia. Also has a dikaryon stage. The hyphae have clamp connections)
Division: Deuteromycota (Molds. Fungi which have lost or nearly lost the ability to sexually reproduce. They form conidia on conidiagenous cells.

Kingdom: Eubacteria (Prokaryotic cells. They have no nuclei, organelles, or microtubules)
Division: Cyanobacteria (Bluegreen algaea. Autotrophic. Use phycobillins during photosynthesis)
Division: Schizobacteria (Heterotrophic)

Kingdom: Archaebacteria (Prokaryotic cells. They have no nuclei, organelles, or microtubules. Live in old habitats. Three types:
Halophiles (Salty habitats)
Methanogens (Produce methane)
Thermophiles (Hot habitats

Kingdom: Plantaea (Mostly autotrophic, multicellular)
Division: Bryophyta (Mosses (Musci) and Liverworts (Hepaticaea). They have no vascular tissues. Gametophyte is dominant)
Division: Pterophyta (Ferns and fern allies. Vascular tissues, sporophyte dominant. No flowers)
Division: Coniferaphyta (Conifers. They produce cones. No flowers)
Division: Anthophyta (Flowering plants. They produce flowers and fruit. Ultimate reduction of gametophyte)

You're on your own with animals, I'm a plant person!

Hope that helped, sorry if I mispelled anything, this is all from memory...

Answer 2

Linnaeus developed the binomial naming system we use today. His was a uniform system of describing life forms that allowed people to be sure they were actually discussing the same thing.
Aristotle classified by blood then by reproduction. He called them by genera and species within the genus.


Plants use photosynthesis to feed themselves-Autotrophic
Animals eat other organisms to feed themselves-Heterotrohpic
Fungi also eat other organisms but have no digestive system even though they are multicellular-Heterotrophic

stamen - male pollen producing part
pistil - female pollen receiving part that has the ovary at the base of the pistil
The ovary is where the seed develops once the pollen fertilizes the ovule
Petals to protect, attract, and guide for pollination.
sepals covered the petals as they developed

Answer 3

Missed the winkie at the end. but, since I'm here The first "cell" was an ancestor to sulphur oxidizing archeobacteria. Photosynthesizing bacteria did not arrive for many millions of years, and it took a long time before they themselves became oxygen tolerant, let alone oxygen efficient. Bacteria are neither plants nor animals. The former classification of protists as animal was inaccurate Victorian anthropomorphism.
