The BCG (Boston Consulting Group) matrix is a tool used by companies to evaluate their business units or product lines based on two dimensions: relative market share and market growth. The matrix divides the business units or product lines into four categories: stars, cash cows, dogs, and question marks.

Stars are business units or product lines that have a high market share in a growing market. These units or lines generate a lot of cash and are considered the main growth drivers of the company.

Cash cows are business units or product lines that have a high market share in a mature market. These units or lines generate a lot of cash, but they do not contribute to the growth of the company.

Dogs are business units or product lines that have a low market share in a mature market. These units or lines do not generate much cash and do not contribute to the growth of the company.

Question marks are business units or product lines that have a low market share in a growing market. These units or lines may have potential for growth, but they require a lot of investment to catch up with the competition.

Now, let's apply the BCG matrix to Reliance, a diversified conglomerate company in India.

Reliance has several business units and product lines, including telecommunications, retail, petrochemicals, and energy.

The telecommunications unit, Jio, can be considered a star. Jio has a high market share in the growing telecommunications market in India and has been a major growth driver for Reliance.

The retail unit, Reliance Retail, can be considered a cash cow. Reliance Retail has a high market share in the mature retail market in India and generates a lot of cash, but it does not contribute much to the overall growth of the company.

It is difficult to classify the petrochemicals and energy units as either dogs or question marks because these industries are subject to fluctuations in demand and prices. However, the petrochemicals unit may be considered a cash cow due to its high market share and cash generation, while the energy unit may be considered a question mark due to its low market share and potential for growth.

Overall, the BCG matrix can help Reliance identify its growth drivers and allocate resources accordingly. It can also help the company make strategic decisions about which business units or product lines to invest in and which ones to divest.

Potato tuber water potential components during storage

Secondly, there could have been some skin left on the tubers which could have affected the rate at which the water entered the tubers due to osmosis. Sweet potato has high concentration of solute molecules. In order for us to appreciate these special adaptation, we first need to know how a typical plant or an animal cell organelle behaves in different water and solute concentrations. Raw Data: Suscrose concentration 0. These sugars are formed when two hexes sugar molecules react together by condensation reaction. However, there were a few anomalies among the group results e. Why are potato cells hypotonic in osmosis solution? During my investigation I will not actually be able to measure a value for, as it is a pressure value kPa.

I am going to make a stock of 1M sucrose solution, that I will dilute using distilled water. At a certain sucrose concentration, there will be no change in mass. This leads to shrinkage of the potato cells, which explains why the potato strips get smaller in length and diameter. The cell is then said to be incipient plasmolysis. In my experiment I incurred anomalous results.

The sucrose solution has a water potential of 0. Here, water molecules are constantly moving in a random fashion. Will potatoes sprout in water? Also I knew that osmosis would take place, osmosis is when water molecules diffuse from a dilute solution into a concentrate solution through a semi permeable membrane. Also another inaccuracy that could have occurred is that the excess water may still have been present on the potatoes when they were weighed. As it is long chain polymers and complex carbohydrates, the bonds which hold them together are hard to be broken down by water. Above this value, the solution becomes hypertonic having a higher solute concentration than the potato and carrot , while below this value, the sucrose solution becomes hypotonic having a lower solute concentration than the potato and carrot. Do potatoes swell with water? The internal water potential of a plant cell is more negative than pure water; this causes water to move from the soil into plant roots via osmosis.

This technique can be observed in guard cells undertaking stomatal opening. Water moves by diffusion across the cell membrane. All you need is a sunny space to grow them, a steady supply of water, and seed potatoes the sprouted portion of a potato that you plant in the ground. In conducting this as an… Effect Of Sucrose Concentration On Osmolality Of Plant Cells The purpose of this experiment was to estimate Osmolality of plants cells i. This is because the water from inside the cells diffused out through the PPM into the high concentrate sucrose solution to try and dilute it and make it equal to the cells sugar concentration. Introduction Joe Riley AS assessed practical investigation The determination of the Water Potential of Potato Tuber Cells Hypothesis I predict that the potatoes in the solutions with the highest sucrose content will shrink and lose weight and that the potatoes in the weakest solutions will gain weight and increase in size. Prokaryotic And Eukaryotic Analysis As the potato has a semi-permeable membrane will allow the diffusion of water molecules to go in and out of the potato, depending on the concentration gradient between the potato and the solutions.

Do potato cells have water?

I have decided to use these values because they were used in the prelim experiment and I felt that they worked well. Plants have strong cell wall made up of cellulose. Therefore, the osmotic pressure and water potential both decrease. We have to make sure the space and surface where the experiment is going to be carried out should be dry and tidy as watery surrounding may affect the results. Evaluation D1 I consider my results to be appropriate in meeting the aims of this investigation as we measured the change in mass of the potato as opposed to measuring the change in length as it will give an indication of the amount of water entering the potato and carrot due to osmosis.

Investigation To Find The Water Potential Of Potato And Carrot Tubers Definition Example

water potential of potato

In pure water, there is no solute molecule therefore the concentration of water is higher then the potato which have high concentration of solutes than that of water. It as a very high tensile strength which makes the cell to withstand the large pressures that develop within it as a result of osmosis. Get your paper price 124 experts online The highest water potential is found in pure water, where no solutes restricts the movement of water. This will be done by putting cores of apple tissue in sucrose solutions of different concentrations and measuring the changes in mass of the apple cores. Starch is insoluble in water because it is formed when many macroeconomics condense together to form long chains.

This is because the cellulose cell wall prevents it from bursting. If the solution surrounding a cell has the same solute concentration as the cell then water ill pass equally between them. What is the water potential of the cytoplasm of the cell? The mass of the potato disks will decrease after they have been incubated in a hypertonic solution. After the results have been gathered, appropriate estimations can then be made as to what the osmotic concentrations of the potato tuber cells are. Error occurred between 0.

The null hypothesis states that there will be no change of mass of the potato disks after they have been incubated in any sucrose solution. This is because the prelim results showed that water moved into the potato when it was put in 0. Scalpel Allows me to cut an accurate length of potato Cutting Tile Stops me from cutting into the work surface Balance Scales Accurate weighing of the potatoes Paper Towels Clean up any spillages and remove solution from surface of potato Boiling Tubes Larger than test tubes so it will allow me put 5 potato cylinders in them Boiling Tube Rack Allows me to keep the boiling tubes upright. This could be due to inaccuracies in the experiment. How do potatoes and potatoes grow in water? Hypothesis: Based on results obtained from the water potential equation, I synthesize that when placed in a hypertonic solution, a potato core will have positive water potential in respect to its environment, meaning the direction of osmosis will be from the potato to the solution. Slice up each cylinder of potato into 6 equally sized pieces and place onto filter paper, making sure that the groups of 6 are kept together and not mixed with any other group of six from another cylinder. Anomalies are visible in results.
