1.) Roots support photosynthesis and respiration by absorbing minerals and water and by storing organic nutrients. They also anchor the plant. Some roots have mycorrhizae‚ which increase the surface area and therefore increase the absorption. The endodermis‚ which is the innermost layer of cells in the root cortex‚ surrounds the vascular cylinder. It is the passage of minerals from the cortex into the vascular tissue. The stem has a system of nodes where leaves are attached. They have a waxy

Enzyme Catalysis Lab: Laboratory Write Up Problem/Question: What happens to the amounts of gas produced in a catalyzed reaction of Hydrogen Peroxide when the catalyst is mixed with an acid? Theory/Hypothesis: In this experiment the researcher and their team will be performing tests on a catalyst (proteins found in potato) to see what will happen when the catalyst in a Hydrogen Peroxide reaction is treated with an acid before the reaction occurs. The researcher hypothesizes that the after treating

The plants used in this experiment are called Wisconsin fast plants‚ due to their extremely short life cycle. In just 40 days‚ the plants germinate‚ grow‚ flower‚ and die‚ which makes them convenient to study in classroom experiments. They are members of the crucifer family and are related to other plants like broccoli and cabbage. In this experiment‚ 8 fast plant seeds were planted in a self-constructed bottle-growing system‚ and they were left to grow for 7-14 days. The Net Primary Productivity

-Get into the world of Fun! This handout is about population ecology‚ YEAH!!!- [Chapter 53 Handout] What is a population? Population: Group of individuals of the same specie living in the same general area. * Why is population ecology important? * Allows for monitoring of organisms impact on environment and also helps to regulate impact. * Helps to preserve populations of organisms. * Ecologists efforts have helped to preserve endangered animals such as the BALD EAGLE TOOLS
