Document Summary

Eudicots: broad leaved flowering plants such as soybeans, roses and sunflowers. Both these organisms, all organs are organized in two systems. Shoot system: the aerial parts of a vascular plant, consisting of the leaves, stems, and flowers. Blade: thin, flat structure attached to the stem. Nodes: points of attachment of leaf to stem. Root system: anchors plant in place and provides nutrition; high surface to volume ratio of roots allow them to absorb water and mineral nutrients from the soil; two typical types of root systems. Taproot system: single, large, deep growing primary root accompanied by less prominent lateral roots. all roughly equal in diameter. Fibrous root system: composed of numerous thin roots that are. Tissue systems: adventitious roots are roots that arise above the ground. Tissue: an organized group of cells that have features in common and that work together as structural and functional units. Vascular tissue system: the plant"s plumbing or transport system.

Which of the following was one of the earliest changes thatcontributed to the success of plants transitioning from aquatic toterrestrial ecosystems?
a. The ingestion of photosynthetic bacteria, enabling plants tophotosynthesize
b. The development of vessels to transport water
c. The development of roots to obtain nutrients and water fromsoil
d. Spores or zygotes encased in a tough coat to resist dryingout
e. The development of flowers to attractpollinator

Is it B or D? I would assume D is the seed of a gymnosperm.According to the info below, that came after the evolution ofvessels to transport water.

The oldest fossils reveal evolution of non-vascular plants bythe middle to late Ordovician Period (~450-440 m.y.a.) on the basisof fossil spores.
These first non-vascular, "amphibious" plants, were limitedprimarily to lowland, wet areas, of temperate to tropicallatitudes. Still most land areas were barren.
By some 420 m.y.a., seedless vascular plants evolved which werebigger and more diverse than their ancestors. These seedlessvascular plants required water for sperm to reach the eggs and werestill limited in their distribution to wet climates. These seedlessplants grew to tree size, reaching 10 or more meters by the lateDevonian (~370 m.y.a.). Lowland swampy environments had abundantseedless plants.
After the 1st land plants evolved (approximately 450 m.y.a.)they underwent rapid expansion and radiation with great forests byMiddle DevonianPeriod. (385 m.y.a.). Although these forests were limited in theirextent, vast quantities of organic material were deposited andpreserved in swampy environments. Through time and burial, thisorganic material was converted to coal, forming the firstsignificant coal deposits of Earth history.
At a similar time (late Devonian, ~375-360 m.y.a.), seedbearing gymnosperm plants (non-flowering) evolved. The developmentof the seed allowed plants to proliferate and spread to drier areasof continents. Gymnosperms became the dominant plant type between~290 to 145 m.y.a. and are still common today.
During the final days of the dinosaurs (Cretaceous), the finalchapter of plant evolution began. This was the evolution offlowering plants (angiosperms). During the Cretaceous Period,angiosperms began overcoming non-flowering plants as the dominantland plants. Since this time they have become the dominant landplants.

In coffee plants that ability to flower continuously (f) is recessive to seasonal towering (F), and non crinkled leaves (c) is recessive to crinkled leaves (C). A continuous flowering variety with normal leaves was crossed to a seasonal flowering strain with crinkled leaves. The F1 plants all flowered seasonally and all had crinkled leaves. A cross between F1 plants produced the following progeny: continuous flowering, crinkled continuous flowering, non crinkled seasonal flowering, crinkled seasonal flowering, non crinkled what are the genotypes of the P1 and F1 individuals? IF the F2 generation consisted of a total of 96 plants approximately how many plants would be expected to occur in each F2 phenotypic class? How many plants would be expected to be heterozygous for both characters out of the 96?

Week 6 Tree of LifeOn-line Work and Preparation:Tell me about the Angiosperm Phylogeny Group III system of flowering plant classification. When was it released, and why was it so important?Using the plant you are working on for your poster, break down each division of its scientific classification from Plantae through to the genus. What features allocate your plant to each of the divisions? Algonquin College BotanyFor example with tulips:Kingdom:PlantaeTulips are multicellular and photosynthesize. They are largely immobile as with all plants, and use chloroplasts to fix carbon dioxideDivision:AngiospermsTulips are flowering vascular land plants. They create a modified stem that creates a specialized reproductive organ. They produce seeds that have endosperm and a protective coating.Order:LilialesTulips are lilies â they are monocotyledonous (they form only a single cotyledon when germinating, and are perennial.Family:LiliaceaeTulips belong to Lilacaea because they have a large flower arranged into symmetry of six colored petals, two whorls, six stamens, and a large central ovary.Subfamily:LilioideaeTulips belong to Liloideae because they are found in the northern hemisphere, and have a single main bulb structure to their roots.etcWrite 500-1000 wordsUpload the document into your week 6 Discussion forum and respond to any two studentâs posts.
