Experiment one Pre-Lab Questions 1. Hypothesize why a fungus would use spores as a mechanism for reproduction. * Spores are small and light and can help fungus reproduce both sexually and asexually. A fungus would use a spore to reproduce because when they land in the right conditions, they germinate and grow new hyphae. 2. How might the environment affect a fungus reproducing sexually or asexually? * Because if the environment is not how it needs to be the fungus will

of organisms whose cells lack a membrane bound nucleus. They are unicellular organisms, although a few such as myxobacteria have multicellular stages in their life cycles or create large colonies like cyanobacteria. Prokaryotes do not have a membrane bound nucleus, mitochondria,or any other membrane bound organelles. In other words, all their intracellular water soluble components(proteins, DNA, and metabolites) are located together in the same volume enclosed by the cell membrane, rather than

four basic human body structure units are cells, tissues, organs and systems which, all working together make the human body function. The cells are the core structure that make up the human body, although there are many different shapes, sizes and types they consist of three main parts, the cell membrane which maintains the shape of the cell and separates and controls the movement of material into and out of the cell, the nucleus which contains the cells DNA and determines its structure and function

of Biology which refers to large number of different species that can be found on earth as well the diversity within a particular species. Also, genetic diversity is affected by several ongoing natural issues that are related to mutation, sexual reproduction, migration, and the size of the population. The first issues that related are mutation. What is mutation? Mutation defined “an organism that has characteristics resulting from chromosomal alteration,” (www.thefreedictionary.com, 2008). The issue

of Living things/ Cellular Reproduction Teacher: Ms. Raines and Ms. Pass Date: 02-12-11 Essential Question: What are some characteristics that make up a living thing, how can you identify if something is living or nonliving? Standard: S5l3. Students will diagram and label parts of various cells (plant, animal, single-celled, multi-celled) a. Use magnifiers such as microscopes or hand lenses to observe cells and their structure. b. Identify parts of a plant cell (membrane, wall, cytoplasm

Virus and Bacteria Virus - A virus is a capsule of protein that contains genetic material. A virus cannot reproduce on its own; it must infect a living cell to grow. Bacteria - Bacteria are one-celled organisms that live on their own. They can multiply and reproduce by subdivision Bacteria and viruses cause many of the diseases we are familiar with and may sound synonymous; they are greatly different from each other. [pic] o They differ greatly in size. The biggest viruses are only as
