Assignment: 10/6/21 Plant cell water potential DAY 1

Due: Oct 6, 2021 by 11:59pm

Today you will set up an investigation to determine the water potential of a plant cell. As plants rely on passive diffusion for the movement of water and nutrients into and through their tissues, water potential predicts this movement and helps us understand where a plant can and cannot survive due to the type of water that it would have to live in contact with.

By the end of today:

Select a plant tissue (Potato, sweet potato, squash, etc.)

Cut samples with a consistent SA - V ratio and a significant enough mass to minimize sampling error.

Record initial mass data for each treatment concentration.

Set up, label and cover each treatment concentration.

Clean up lab station.
