BGY 2001 CONCEPT OF BIOLOGY Laboratory Report PRACTICAL 8 TRANSPIRATION Tittle: Transpiration Objectives: 1. To measure transpiration rates by using photometer. 2. To determine the factors that influences the rate of water loss from a plant through transpiration Introduction: Most of the water a plant absorbs is not used for a plant’s daily functioning. It is instead lost through transpiration‚ the evaporation of water through the leaf surface and stomata‚ and through guttation

Laboratory Report 4: Invertebrate Animals Section: I Table: 6 Date: September 26th‚ 2013 Introduction: In our group‚ our task was to observe the selected four invertebrates and familiarize ourselves with their taxonomic levels through the organism’s mechanisms of feeding‚ motility‚ and reproduction. Our group used the prior knowledge we possessed about the Hydra‚ Rotifer‚ Gammarus‚ and Planaria organisms to complete the lab. We knew that all of these small invertebrates have a

1Achievement Standard Biology 91155 Demonstrate understanding of adaptation of plants or animals to their way of life Biology 2.3A 3 credits All animals including insects‚ fish‚ and mammals have adaptations in some form of internal transport that allow them to carry out their way of life. Adaptations such as the different structures of the transport of nutrients and wastes‚ the gas exchanges‚ and the support and movement of the animal all take part in how each of the different animals operate
