cell wall surrounding them. When the take up water by osmosis they start to swell‚ but the cell wall stops them from bursting. When they are put in dilute solutions‚ plant cells turn out to be “turgid” (swollen and hard). When the pressure inside the cell increases; No more water can’t enter the cell because the internal pressure of the cell is really high. “When plant cells are placed in concentrated sugar solutions they lose water by osmosis and they become “flaccid”; this is the exact opposite

Potato Osmosis Introduction: A shipwrecked sailor is stranded on a small desert island with no fresh water to drink. They know they could last without food for up to a month‚ but if they didn’t have water to drink they will be dead within a week. Hoping to postpone the inevitable‚ their thirst drives them to drink the salty seawater. They are dead in two days. Why do you think drinking seawater killed the sailor faster than not drinking any water at all? Today we explore the cause of the sailor’s

The effect of salt concentration on osmosis in potato. Introduction: 1. The purpose of doing this lab is to observe the effects of various solute concentrations on osmosis in a potato. 2. During osmosis‚ water moves from the side of the membrane where they are most concentrated to the side where they are less concentrated. If the concentration is equal on both sides‚ there will be no movement. 3. I hypothesize that the mass of the potato will decrease as the salt in the solution

Question1 Quantitative data are measures of values or counts and are expressed as numbers (www.abs.gov.au). In other words‚ quantitative data are data about numeric variables (www.abs.gov.au). Four types of quantitative data are interval‚ nominal‚ ordinal and ratio. Firstly‚ interval scales are numeric scales in which we know not only the order‚ but also the exact differences between the values (www.mymarketresearchmethods.com). Other than that‚ interval data also sometimes called integer is measured

Qualitative data analysis What Is Qualitative Analysis? Qualitative modes of data analysis provide ways of discerning‚ examining‚ comparing and contrasting‚ and interpreting meaningful patterns or themes. The varieties of approaches - including ethnography‚ narrative analysis‚ discourse analysis‚ and textual analysis - correspond to different types of data‚ disciplinary traditions‚ objectives‚ and philosophical orientations. What Is Qualitative Analysis? We have few agreed-on canons for qualitative

SOCIOLOGICAL METHODS TYPES OF DATA Sociologists have two types of data available to them: information they have self-generated for their own research purposes (primary data)‚ and already existing data that was not specifically created for sociological purposes (secondary data). Primary data can result from‚ the employment of questionnaires‚ structured‚ semi-structured and unstructured interviews‚ and observation techniques. Secondary data is more or less‚ anything else: statistics produced

Investigating the Osmosis Effect in Potato Cores Aim The aim of this experiment is to investigate the osmosis effect in potato cores while they are submerged in different concentrations of sucrose solution. Osmosis will take place while the potatoes are fully submerged in the sucrose solution. Apparatus æ Scalpel (1) æ Tile (1) æ Pr.

Introduction The movement of water molecules across a semi-permeable membrane is the process of osmosis. If there is a solute and a solvent‚ each containing different concentration levels‚ then the water would move along its concentration gradient until each side of the membrane are equal. The water moves because the membrane is impermeable to the solute and the solute concentrations may differ on either side of the membrane. Water molecules may move in and out of the cell‚ but there is no net diffusion
