of vascular tissues‚ together they for vascular bundles and are responsible for the survival of the plant. Xylem flows only from bottom up to the top and Phloem flows both ways. Phloem is the innermost layer of the bark in most trees. Outer Phloem is dead cells and inner Phloem is living cells‚ when the primary Xylem cells become dead‚ losing their conducting function and forming a hard skeleton that serves support to the plant. Xylem is part of a vascular tissue. The vascular tissue transports fluids

Economic Viability in Commercial Urban Aquaponics by Alexandre Joaris CAPSTONE THESIS SUBMITTED IN PARTIAL FULFILLMENT OF THE REQUIREMENTS FOR THE DEGREE OF Bsc Sustainability LEIDEN UNIVERSITY COLLEGE THE HAGUE Submitted to: Dr. Peter Houben 2015 Introduction There is a growing academic concern that Earth will not be able to feed a human population that exceeds nine billion individuals. Thus‚ agriculture is an increasingly import focus of research and technology. Although‚ it has always

We found that the epidermal and the cheek cells do differ in the shape and scar tissue and healthy tissue also differ. Introduction In the human body‚ the skin is the largest organ. As well as being the biggest organ in the body‚ the skin is one of the most important‚ not only to humans‚ but to all organisms that have it. Most skin cells

FlowCAM® Application Note #105 Yeast Viability Measurements in Fermentation Studies Objective An important component of fermentation processes is to continually monitor yeast growth and viability. The most common method for doing this is using the ASBC hemocytometer count method. In this method‚ samples are taken from the fermentation vessel‚ stained with methylene blue‚ and then counted manually under a microscope using a hemocytometer. While this method is well known and documented

Skeletal muscle atrophy is a common pathologic adaptation to skeletal muscle disuse (commonly called "disuse atrophy). Tissue and organs especially susceptible to atrophy include skeletal muscle‚ cardiac muscle‚ secondary sex organs‚ and the brain. Hypertrophy is an increase in cell size. If enough cells of an organ hypertrophy so will the whole organ. The heart and kidneys

Stomach The stomach has three layers of non-striated muscle in its wall and an inner lining of columnar epithelium with goblet cells. The tissue connecting the lining with the muscular coat is areolar tissue. Non striated muscle is a type of muscle tissue‚ which is also called involuntary‚ smooth or plain muscle. It still contains the protein filaments; they
