- Speedwriting is a shorthand writing system developed in 1924 by Emma Dearborn, an instructor at the University of Chicago.peedwriting uses a stylized script made in 1942 for faster handwriting, in which the ‘t’ is uncrossed (l is looped to distinguish them), ‘i’ is not dotted, ‘m’ is a simple curve like a stretched ‘n’ and 'w' is also a simple curve like a stretched 'u'.

PLANTS AND THEIR STRUCTURE Parenchyma | Back to Top. A generalized plant cell type, parenchyma cells are alive at maturity. They function in storage, photosynthesis, and as the bulk of ground and vascular tissues. Palisade parenchyma cells are elogated cells located in many leaves just below the epidermal tissue.hloem cells are usually located outside the xylem. The two most common cells in the phloem are the companion cells and sieve cells. Companion cells retain their nucleus and control the adjacent sieve cells. Dissolved food, as sucrose, flows through the sieve cells. Phloem cells.

Representative members The living sieve elements that comprise the phloem are not lignified. Xylem and phloem are collectively called vascular tissue and form a central column (stele) through the plant axis. The ferns, gymnosperms, and flowering plants are all vascular plants.

- phlo·em. A tissue in vascular plants that conducts food from the leaves to the other plant parts. Phloem consists primarily of tube-like cells that have porous openings. In mature woody plants it forms a sheath-like layer of tissue in the stem, just inside the bark. See more at cambium, photosynthesis. Compare xylem.

Plant question: Please define xylem, phloem, dermal tissue, vascular tissue, and ground tissue.? In vascular plants, phloem is the living tissue that carries organic nutrients (known as photosynthate), in particular, sucrose, a sugar, to all parts of the plant where needed. In trees, the phloem is the innermost layer of the bark, hence the name, derived from the Greek word φλοιός (phloios) meaning bark.his causes water to move into the sieve-tube element by osmosis, creating pressure that pushes the sap down the tube. In sugar sinks, cells actively transport solutes out of the sieve-tube elements, producing the exactly opposite effect. Some plants, however, appear not to load phloem by active transport.

Phloem Structure Phloem Structure Phloem is composed of several cell types including sclerenchyma, parenchyma, sieve elements and companion cells. The sieve element and companion cell are found closely associated with each other in what is referred to as the sieve element/companion cell complex.

What are the similarities and differences between xylem and phloem? Best Answer: Xylem and phloem are the two components of the vascular system in higher plants. Xylem is composed of two different types of cells-tracheids or vessel elements. These cells are dead when they are functioning and that function is to transport water through the plant.(Remember that water movement occurs by Transpiration-Cohesion-Tension).hloem is a living tissue, composed of sieve tube cells, and its primary function is to transport nutrients (in sap) throughout the plant. As opposed to xylem which only transports water up the plant, phloem transports nutrients up or down, depending on where the nutrients are greatest.

Seedless Vascular Plants Phloem tissue is responsible for translocation, which is the transport of soluble organic substances, for example, sugar. The substances travel along sieve elements, but other types of cells are also present: the companion cells, parenchyma cells, and fibers.

- 1 Secondary phloem is the secondary growth tissue that conducts food that the plant makes from the leaves to the rest of the plant. 2  The cork cambium is involved in producing the tough, thick covering of a stem and root. 3  Secondary xylem is the wood of a tree trunk. Secondary xylem is the wood of a tree trunk. 2  The annual rings are created by alternating bands of summer wood cells and spring wood cells. 3  The summer wood cells are smaller in diameter, due to less available water, while the spring cells are larger in diameter due to rapid growth from more abundant water.

The Plant Body Phloem tissue, which transports organic compounds from the site of photosynthesis to other parts of the plant, consists of four different cell types: sieve cells (which conduct photosynthates), companion cells, phloem parenchyma, and phloem fibers.

- Phloem tissue carries sugar from the leaves to other cells of the plants. Non vascular plants are plants that lack tissues that transport water, nutrients, and sugar. Some example of non vascular plants are mosses, liverworts, and hornworts.Non vascular plants don't have tissues to carry the materials that cells need to stay healthy. Because of this, they don't grow very large.osses and a … few other plants are called nonvascular plants, meaning that they do not have a vascular system. in plants, the vascular system is like the circulatory system in humans. The two parts, the Xylem and the Phloem, are like the arteries and veins that carry our blood.

Xylem and phloem 1 of 6. Plants have tissues to transport water, nutrients and minerals. Xylem transports water and mineral salts from the roots up to other parts of the plant, while phloem transports sucrose and amino acids between the leaves and other parts of the plant.

- The sugar and other organic molecules are transported through the plant by means of a special layer of tissue called phloem. Phloem is composed of living cells that transport a water solution of sugars that we commonly call sap.This movement is modeled by the pressure-flow theory, a part of which is that the sugar-containing fluid is moved through sieve tubes by fluid pressure.he sugar and other organic molecules are transported through the plant by means of a special layer of tissue called phloem. Phloem is composed of living cells that transport a water solution of sugars that we commonly call sap.

What is the definition of a vascular tissue? ( lot more questions inside but 10 points to whoever answers all) Its basic function is to transport water to know more aboutxylem go with pictures go to http://en.wikipedia.org/wiki/Xylem In vascular plants, phloem is the living tissue that carries organic nutrients (known as photosynthate), particularly sucrose, a sugar, to all parts of the plant where needed.he cells in differentiated vascular tissue are typically long and slender. Since the xylem and phloem function in the conduction of water, minerals, and nutrients throughout the plant, it is not surprising that their form should be similar to pipes.

Sap Sap is a fluid transported in xylem cells (vessel elements) or phloem sieve tube elements of a plant. These xylem cells transport water and nutrients throughout the plant.ylem sap consists primarily of a watery solution of hormones, mineral elements and other nutrients. Transport of sap in xylem is characterized by movement from the roots toward the leaves.
