Investigation of Osmosis in Plant Tissue Aim To investigate factors which affect the rate of osmosis. The main factors which affect osmosis are: Pressure Temperature Surface area Solute Concentration Plant Tissue We will be investigating solute concentration as this is the easiest factor to measure and will give us the most accurate results. We will mainly investigate the different rate of osmosis when potato cells are placed in solution with different solute concentrations
An Experiment to Investigate Osmosis in Plant Tissue Aim: To conduct an investigation to compare the osmotic behavior of two types of plant tissue in varying concentrations of sucrose solution. To find the point at which there is no change in mass or length of a specific plant tissue in a certain sucrose solution, the point of equilibrium, where sucrose and water contents are both equal in the solution and the tissue. Introduction: When a plant cell is placed in a sucrose solution there
Water Relations in Two Plant Tissues Results: Table 5 Table to show the sucrose concentration and water potential of each tissue. The sucrose solution was extrapolated from graph 1, which shows the percentage change of mass of the tissues when immersed in the different sucrose solutions. A line of best fit was drawn, where the line of best fit intercepts the x-axis (concentration of sucrose solution) is the sucrose concentration of the tissue because at this point there is no mass
carry viruses and fungal pathogen (Jong, 2012). Therefore, tissue culture is the alternative to the conventional method for banana production. Tissue culture method benefits the production of bananas by producing plants that are free of diseases, faster growth rates, greater yield and safe for human consumption (Increasing banana yields by using tissue culture method, n.d.). According to Tissue Culture (n.d.), the main purpose of tissue culture is to produce healthy plantlets that are free of virus
strong psychedelic mental affects when smoked, injected, snorted, or when swallowed orally (with an MAOI such as haramaline). DMT was first synthesized in 1931, and demonstrated to be hallucinogenic in 1956. It has been shown to be present in many plant genera (Acacia, Anadenanthera, Mimosa, Piptadenia, Virola) and is a major component of several hallucinogenic snuffs (cohoba, parica, yopo). It is also present in the intoxicating beverage ayahuasca made from banisteriopsis caapi. This drink inspired
cancerous cells requires gene alterations. Altered genes and uncontrolled growth may lead to tumors. These tumors can be benign (NOT cancerous) or malignant (cancerous). Benign tumors won’t spread but it can damage tissues around it. Malignant tumors invade, damage, and destroy nearby tissues and can spread. Cancer can spread throughout the body when cancer cells break away from malignant tumors and enter the bloodstream. Cancer cells from breast cancer are mostly found in the lymph nodes under the
can be recognized as not normal tissue. These traits are passed down as the cell reproduces therefore spreading the cancer. Neoplasms are generally classified into two groups: malignant and benign. Malignant tumors, or abnormal tissue, grow more rapidly than benign tissue and they invade normal tissue. Benign tissue is structured similar to normal tissue while malignant tissue is abnormal and has an unstructured appearance. Of greater importance, benign tissue does not metastasize, or begin
Determining the Concentration of the Cell Sap in Potato Storage Tissue Aim: To determine the concentration of the cell sap in potato storage tissue. By using Osmosis, determine what the sugar concentration of cell sap is. Prediction I predict that the potato segment in the distilled water will definitely gain in weight because the solution outside it has a much higher concentration of water then in the cell sap meaning Osmosis will occur and the potato segment take in water. I predict
Investigating the Factors that Affect Osmosis in Living Tissue Aim: To investigate the factors that effect osmosis in living tissue. Planning: Introduction Essentially, osmosis is the diffusion of water across a selectively permeably membrane. Osmosis is one of the ways by which substances enter and exit cells. Other ways include diffusion, the Donnan effect[1], solvent drag, filtration, endocytosis, exocytosis and active transport. All of these methods are necessary to provide
of plant from the family of Solanaceae. There are many tomato species around the world. The tomato is not easy to plant in Malaysia and it is also very important as a food for the citizen. This tomato plant is easy to cultivate in area which is in moderate temperature and firstly came from the place which is in dry west coast of tropical South America (Cooper, 1972). According to Picken, Stewart, and Klapwijk (1986), there are several techniques for growing tomato plant which is first plant the
Authors have explained the ramification and growth of post surgical scar tissue on the fascial system, despite that literature explains a scope of theories. This appraisal will focus on its major thesis questioned and emerged frequently by many authors ,this review will begin with emphasising on the justification of all findings subsequently. Hence investigating all current postulation in the literature on post surgical scar tissue development and effect on the fascial system, this study consequence
This conductive hearing loss is caused by the growth of a spongy bone-like tissue that prevents the ossicles (bones of the middle ear) from moving well. One of the first signs is a small growth of the tissue in the middle ear. This is often in front of the oval window, which separates the middle ear from the inner ear. This can begin in early childhood or adolescence. The tissue may grow rapidly and become hard. The bone tissue grows over the stapes ossicle attaching it to the oval window. At first
aureus food poisoning, but in some instances individuals will require more time to fully recover. Even though S. aureus is mainly associated with food poisoning, the bacterium can penetrate the skin or other mucous membranes to invade a range of tissues which will cause a variety of infections. Superficial infection of the skin can cause boils, impetigo, styes (infection of the glands or hair follicles of the eyelids), folliculitis, and furnacles. All of these infections are charac... ... middle
Forensic Pathology as a Career The career that I researched was forensic pathology. The job of a pathologist is to determine a person’s cause of death by examining tissues and fluids from the body. A forensic pathologist does this as well, but they are trained to examine people who died unexpectedly or violently and to recognize other things that a regular pathologist might not, such as recognizing something as intentional rather than accidental. They have to determine who the person is, the time
life when life extension and anti-aging have become a reality. However, there is a lot of damage done to the body during this freezing, says Dr. Ralph Merkle, a professional in the field of cryonics. First there are fractures that form in the frozen tissues caused by thermal strain, if you were warmed up you’d fall into pieces as if cut by thousands of sharp knives. And Second, the Cryotransport is used as a last resort because legally the Cryotransport can’t even begin until the patient is legally dead
unnoticeable. The next stage of the measles happens after eight to twelve days. The infected person has symptoms of fever, weakness and loss of appetite. Coughing and running of the eyes and nose are also seen. Now the infection is spreading all over the tissues through out the body. They also trigger the body’s immune system, which causes the symptoms. When the measles virus infects the immune system and interacts with the antibodies and T cells, a measles rash begins on the face and very quickly spreads
inflammation of the bursa that is easily prevented, detected and treated. Bursitis is a common condition that can cause much pain and swelling around an affected bursa. A bursa is a sac between body tissues that move against each other. They are filled with a lubricating liquid to minimize the fiction between the tissues. The bursa are found mostly in joints between skin and bone or bone and tendons. When you irritate these lubricating sacs, the bursae fill with fluid and become irritated and inflamed. This
The Orchidaceaeis a diverse and widespread family of flowering plants with blooms. And Dendrobium is a huge genus of orchids which have most marketing value among other orchids in the world. Orchids with their bewildering range of flowers and beautiful color combinations provide a source of profound aesthetic pleasure to both owners and visitors. The striking resemblances of their flowers to various forms of animal life behold the attention of everyone who looks at them. Orchids are excellent item
Cutaneous membrane also know as the skin. The cutaneous membrane actually has a surface area of over 20 feet and is actually an organ, comprised of all four tissue types, epithelial, connective, muscle, and nervous. Because of this and having several accessory organs, the Cutaneous membrane is considered to be an organ system. The cutaneous membrane is comprised of three different layers, the epidermis, the dermis, and the hypodermis, each with their own purpose and characteristics. The epidermis
Damaged tissue (inflammation) Inflammation is the body’s response to injury. Inflammation is a protective attempt by the body to attempt to remove harm and to initiate the healing process. Inflammation occurs with a few minutes of the incident up to a few hours after depending on the severity of the injury. There are 5 key characteristics of inflammation these are: • Pain • Redness • Swelling • Heat • Immobility (loss of use) Injury causes Tissue damage.
