properties involved are cohesion and surface tension. Cohesion plays a consequential role in the transport of water within plants specifically within the phloem. Surface tension also dictates an important role within the transpirational pull of the xylem.)

The three main theories as to how xylem transports water and minerals are root pressure‚ capillary action‚ and cohesion-tension/transport pull. The root pressure theory works by the water being pumped into xylem tissue. Then‚ the minerals and ions absorbed with the water then get pumped up the root. The water then follows the ions and minerals up the xylem‚ and throughout the plant. Capillary action works by relying on the adhesive properties

Investigation‚ live plant specimens of flowering plants would be used to classify plants as monocots or dicots. Hypothesis: Monocots have one embryonic seed leave while Dicots have two. Monocots have one cotyledon in seed while dicots have two. Xylems and Phloem are in circular shape in dicots‚ while monocots’ are scattered. Monocots have the multiples of 3 petals while dicots can have 4/5 petals. Monocots have parallel leaf veins while dicots have branched leaf veins. Safety Precautions:

DNA- is the material found in the nucleus that contains the genetic info. 4 billion codes in length Gene- a segment of DNA that controls a certain protein production. A gene is made up of hundreds to thousands of codes. Chromosomes- genetic material that is coiled up into structures during cell division.

pulled through xylem in plants. It is also a transport medium‚ just like in animals‚ substances‚ such as ions are dissolved in it and carried in the xylem. Hydrogen bonds are formed between the oxygen of one water molecule and the hydrogen of another. As a result of this‚ the water molecules have an attraction for each other known as cohesion. Another method of water movement up the xylem is by cohesion-tension theory. The molecules of water are attracted to the walls of the xylem (adhesion) due

CELL STRUCTURE CELL THEORY: Structural and functional unit of all living things New cells arise from already existing cells Cells contain information that instructs growth. This information can be passed onto new cells.

Foliar and Root Anatomy of Evergreen Tree‚ Citrus Limon (Rutaceae) Abstract: Foliar and root anatomy were obtained from a Citrus Limon to be studied upon and the main focus were the stem‚ petiole‚ leaf and root. Plant material was obtained from Manila Seeding Bank Foundation Inc. and was brought to Ateneo De Manila University. Sections were subjected to staining and dehydration‚ after which they were viewed under a light microscope and measured using a light microscope. The young stem has a periderm

over the course of a two week campaign with a “BOGO” (Buy one get one free) beverage offer. The Approach Guided by digital advertising agency Xylem CCI’s media agent‚ JL 360‚ Jamba Juice decided to conduct a pure online campaign. This campaign was targeted primarily at women‚ who predominate among Jamba Juice’s customers. 24/7 Real Media was chosen by Xylem CCI and JL 360 to be the digital advertising partner. The resulting campaign included multiple creative variants in different banner formats.
