Osmolarity and tonicity - an inquiry-based lab experience to design and run an experiment to determine the internal osmolarity of plant raw tubers or root. The mass of th e potato will change based on the molarity of the solution it is placed in chemistry refresher: molarity is the amount of moles of a substance per liter(of water) if the. This information helped us estimate the osmolarity of the potato tuber tissue our group hypothesis is that the osmolarity of the potato will have the concentration with the 01 m solution. Social issues term papers: biology lab - estimating osmolarity by change in volume of potato tuber tissue.

Potato tuber (solanum tuberosum l cv bintje) callus shows a decrease in fresh weight and an increase in dry weight upon transfer to nutrient medium supplemented with 03 or 05 m mannitol the osmolarity of the intracellular fluid increases simultaneously. Effect of chlorocholine chloride, sucrose and when the number of shoots was maximum the cultures were shifted on tuber induction tissue culture potato is. Different sugars such as saccharose or trehalose may be added as cryoprotecting agents or for adjusting osmolarity of the solution frozen tuber tissue from 10. The instructor will use a french-fry cutter to cut uniform sticks of potato tuber tissue you will be provided with 21 uniform sticks from this one potato the remainder of the potato will be wrapped in plastic film for further use (part iii.

The water potential of the potato would decrease because water moves from a high water potential region to a low potential region, and a dehydrated potato cell is hypertonic in comparison with the environment. Estimating the osmolarity of plant cells purpose: to estimate the osmolarity of potato tuber tissue by finding the molarity where the weight of the potato tuber tissue does not change. Effect of sucrose molarity on potato tuber weight using sucrose solutions to determine osmolarity of potato tubers based on weight by thomas pelikan biology 200a section 004 kimberly schmidt october 2, 2012 abstract: in this experiment we were trying to determine the osmolarity of potato tubers by weighing them before and after incubating them in solutions of sucrose with varying molarities.

Osmolarity of potato cells lab reportpdf •hypothesize about the osmolarity of potato tuber tissue in relation to you will estimate the osmolarity of potato. Objective the objective of this lab is to measure the water potential of potato tuber tissues we will monitor water uptake or loss by tissues in different sucrose solutions to identify an isotonic solution with water potential equal to that of the tissue. The sucrose transporter stsut1 localizes to sieve elements in potato tuber phloem and influences tuber physiology osmolarity of the apoplasm and thus regulate. The lower salt concentrations result in an increase in length of the potato strip, meaning water has entered the potato strips by osmosis this means there is a higher water potential inside the.

Sucrose solutions of known molarity to find the weight or volume of the potato tuber tissue if it does not change it mean that there has not been no net loss or gain of water the molarity is an indirect measure of th solute concentration of the potato tuber because water movement in plant cells is also affected by the presence of cell walls.
