The Living Regents Examination is at 9:00 a.m. on Friday January 26, 2007
Lab Activity 1 - Relationships and Biodiversity In this lab, students are introduced to classification and the importance of biodiversity. Organisms are according to similar characteristics. Some of these characteristics are physical (structural) and others are Biodiversity is the amount of the different organisms in a given area. Students learn that an important cancer curing drug is found in Botana curus, a slow growing plant that endangered list. They must examine three plentiful similar species to determine which one is most similar to curus . It is hoped that this plant will also produce curol, the cancer curing drug.
classified chemical. is on the Botana
Lab Procedure: The students first compared the structural characteristics of the plants to try to determine which species was the closest structurally to Botana curus . • Students examined the structural (physical) characteristics of the leaves of these plants to determine which one is structurally closest to Botana curus . (Leaves are actual size.)
Physical factors deal with the form or structure of the leaf. The physical factors of a leaf include its size & shape, color, and venation (How are the veins organized?). Fill in the following table: Leaf Species BC Color Light Green Size & Shape Venation Veins connected to center vein branch off to sub-veins All veins are directly connected to center vein All veins are directly connected to center vein Veins connected to center vein branch off to sub-veins
Species X
Dark Green
Species Y
Medium Green
Species Z
Light Green
Base on the physical characteristics of the leaf, which species appears to be most similar to Botana curus? Explain your answer.
