- Title: Osmosis on Zucchini and Cucumber Objective: Explain how osmosis happens in plants such as zucchini and cucumber. PLEASE WATCH THE VIDEO LINK HERE BEFORE ANSWERING THE QUESTIONS. Thank you Youtube link: https://youtu.be/9bPto2f_fGA After watching it, please ANSWER THE QUESTIONS! The Questions: -Explain why and how did this happen to each of the slices of cucumber or zucchini. (In each Set) -Kindly explain exactly WHY did this happen. (In each Set) -What type of solution were present in each set up here? (In each Set) -How did osmosis happen on each of the set ups? (In each Set) You might be wondering what does it mean with the "(In each Set)". So the format on how you will answer the questions above is in Three sets: Set 1, Set 2 and Set 3 (you can see it in the video, MANDATORY TO WATCH IT). FORMAT: SET 1: Answer the questions. SET 2: Answer the questions SET 3: Answer the questions Thank you so much:)Osmosis Practice Activity Osmosis is the diffusion of water from an area of high concentration to an area of low concentration. Only water moves in osmosis! The diagrams below show the concentration of water and salt inside the cell and the concentration of water and salt surrounding the cell. Complete the sentences below by comparing the concentration of the water inside the cell and the concentration outside the cell. 1. a. Water will flow the cell, out of the cell, in both directions).
