  • AP Biology - The Flower Shop (Plant Rap) AP Bio rap about plants set to the song "Candy Shop" by 50 Cent. Pretty much pulled all of our will power (not like there was much to begin with) to create this... especially after the AP test. NYAAHHH. Lyrics: Yeah... uh huh... all them plants I'll take you to the flowershop Let you check out the monocots How about those eudicots? Categories of angiosperms (woah) I'll take you to the flower shop See how water gets to the top Study the plant structures See how it keeps its moisture (woah) [Verse] Angiosperms, known as the flowering plaints Ovaries makes fruits plus seeds and not infants Confusion rising, okay explain the two classes Eudicots are roses and monocots are grasses I'll break it down for you now, students it's simple They're both the same, but different like people Floral parts come in 3 with monocot flowers 4 or 5 in eudicots give more to devour! A tap root system eudicots got 'em But fibrous root systems make monocots ballin' What's the difference between cotyeldons, no problem Eudicots got 2, monos got 1, it's awesome Vascular bundles both have xylem and phloem Scattered bundles makin' it look like they just roamin' Circular bundles lookin' like a small powwow All these differences make you go, "oh wow!" [Chorus... again] [Bridge] Plants what you do (what you do) And how you do (and how you do) The the things you do (the things you do) Are important for the AP test too! (Oh no!)

  • The Biology song. Original. [LYRICS] Water gets taken up by soil. Minerals gets absorbed by ATP Water potential inside the root hair decreases! decreases! Diffusion takes place across the plasma membrane The endormers surrounds the xylem cells Water recieved is then expelled. Travelling through three pathways. Apoplast, symplast and vacuolar too! Water always finds its way through. oh pick a path, pick a path, pick a path through the maze! (teacher and student speech) The Casparian strip can get in the way x2 Resulting in trouble and dismay x2 Pushing the apoplastic stream into the xylem. Root pressure pushes, transpiration pulls. As molecules attract by cohesion. Capillary action creates adhesion. Cohesion, cohesion, cohesion and adesion Cohesion withstands the pull. Whilst Adesion creates a force. A force that pulls x2. Pulls water molecules up the sides of the vescles. Up the sides of the vescels! (Student Speech). Written By Rebecca Howe.

  • What Amoebas Know Science Fiction: The evolutionary history of life on Earth traces the processes by which living and fossil organisms evolved. It stretches from the origin of life on Earth, thought to be over 4500 million years ago, to the present day. The similarities between all present day organisms indicate the presence of a common ancestor from which all known species have diverged through the process of evolution.[1] Real Science: A microbial cyst is a resting or dormant stage of a microorganism, usually a bacterium or a protist, that helps the organism to survive in unfavorable environmental conditions. It can be thought of as a state of suspended animation in which the metabolic processes of the cell are slowed down and the cell ceases all activities like feeding and locomotion. Encystment also helps the microbe to disperse easily, from one host to another or to a more favorable environment. When the encysted microbe reaches an environment favorable to its growth and survival, the cyst wall breaks down by a process known as excystation.

  • transpiration stream - fresh prince of bel air Now this is a story all about how, A water molecule got flipped turned upside down And i'd like to take a minute just sit right there I'll tell you how it got from the root to all the way up there. In the root cell is where it all starts, Getting there by osmosis - isn't that smart So the root cell must have a lower solute potential Than in the ground - so that part is crucial Once inside the waters gotta choose its route Apoplastic - thats through the cell walls to get out Don't forget the symplastic that's through plasmosdesmata Nothing else rhymes except the stomata. Now thats alright till the casparian strip So the water better take a symplastic trip Now into the xylem the water molecule goes Travelling up via root 'n' air pressure, but hey wait that slows So adheion 'n' cohesion help make those water molecules move. So let them get into the groove! Capillary action that's when water attracts to the sides N' the transpiration stream when water uses cohesion 'n' glides Up the xylem as one column of water But don't forget those miniscuses even smaller to pull more water So the water is where it needs to be - but what next Diffusion out through the stomata would be best But only when the water potential is lower outside So you better remember this water ride!

  • Nectar: generation, regulation and ecological functions Nectar contains water, sugars and amino acids to attract pollinators and defenders. Despite the importance of nectar, little is known about the synthesis of its components and the regulation of their secretion. However a recent breakthrough discovery is the identification of a gene that encodes apoplastic invertase of Arabidopsis thaliana, representing the first gene whose function is required for floral nectar secretion. This video presents a vesicle-based, merocrine secretion as the likely commmon mechanism of nectar secretion and highlights the likely roles of invertases for uploading of sucrose from the phloem, carbohydrate mobilization during active secretion and the post-secretory adjustment of the sucrose:hexose ratio of nectar.

  • Dr. Larry Peterson, Botany 2012 Donal R. Kaplan Memorial Lecture The majority of vascular plant species have an intimate association with fungal symbionts, forming mycorrhizas. The fossil record has revealed that this is an ancient association with the success of the first land plants likely dependent on their fungal partners. Most mycorrhizas are examples of true mutualism with both partners benefiting from the association. Mycorrhizal fungi increase the surface area of plant roots for nutrient acquisition and in turn obtain carbon for growth and reproduction. However, plant species that lack chlorophyll depend on fungal connections to obtain carbon from photosynthetic plants; there is no evidence that the fungi receive any benefits from the association. These plants, known as myco-heterotrophs, are therefore cheaters. Mycorrhizas are categorized primarily on the interaction of plant roots with particular fungal species, resulting in characteristic changes in the morphology and cytology of both symbionts. In some cases, such as ectomycorrhizas, the morphology of the root system becomes highly modified resulting in morphotypes that can be useful in identifying the fungal symbiont involved. A critical stage in all mycorrhiza categories is the development of a nutrient-exchange interface between the symbiotic partners. With the exception of ectomycorrhizas, in which fungal hyphae develop external to epidermal and cortical cell walls, other mycorrhiza categories involve the penetration of root cell walls by fungal hyphae and the formation ...
