Standard(s): / SC.912.L.14.7 Relate the structures of each of the major plant organs and tissues to physiologic processes.
Description / Student pairs will collect leaves from 3 different plants, examine them under a light microscope, then count and average the number of stomata on underside of the leaf. Students will use the lab data and their knowledge of leaf stomata to recommend plant species for a Mars mission.
Task / NASA has plans for sending a rover to Mars in 2020. The mission will entail looking for any sign that life inhabited the planet at any time in its history. The mission will also involve studying weather, dust and extracting oxygen from the carbon dioxides laced atmosphere. The goal is to someday place humans on the surface. For future humans to be able to survive on Mars, there must be available plant life in to provide food and hopefully use the carbon dioxide in the atmosphere to produce oxygen. NASA needs your help in determining which plants are capable of converting the most carbon dioxide to oxygen and retain the most water. It would be a huge job to test all of the plants on Earth, so they are asking Biology students around the world to help. Your task is to obtain leaves from 3 different plant species from around your school campus. Identify the species of plant, then use the directions provided to count each leaf’s stomata. After collecting and calculating the data, you are to rank the three plants from 1st to 3rd choice. A justification for the placement of each plant species is also required. Your data collected, results and justifications should be presented in a table format.
Materials / Light Microscopes (one per pair of students)
Clear nail polish
Tweezers
Scissors
Clear packaging tape
Microscope slides
3 plant leaves per student pair

General Info / · This task is designed to take students approximately 90-120 minutes to complete.
· Students will be working in groups of 2 during this activity.
· Walk students around campus to choose and pick fresh leaves. Another option would be to provide leaves for the class to use.
· The following data tables: NASA Plant Stomata DATA and NASA Plant Ranking with Justification, have been provided to support students who need extra support.
· Students should clean microscopes properly before and after use.
· All Safety Procedures should be strictly adhered to.
NOTE: It is recommended that microscopes, clear packing tape and microscope slides be placed at each lab station before class. Also, provide lens paper and alcohol for cleaning the dissecting microscopes.
