    Classification of Living Things Classification of living things is called "Taxonomy." This is when scientists put organisms into groups when they have things in common. The first groups they use are the Kingdoms. There are five kingdoms: ➢ Animal Kingdom ➢ Plant Kingdom ➢ Fungi Kingdom ➢ Protist Kingdom ➢ Moneran Kingdom Each Kingdom is then split into smaller groups‚ called Phyla. Each Phylum is split into smaller groups called Classes‚ each Class is split into

    Movement in and out of cells Diffusion: (mixing molecules) Molecules and ions in a liquid or a gas move continuously. The movement is quite random‚ and the particles change direction as they bump into one another. The particles collide more often when they are close together (when they are concentrated) and so they tend to diffuse‚ or spread out‚ until they are spaced evenly throughout the gas or liquid. The random movement of particles is due to their own kinetic energy. When the diffusion

    Abstract Stomata is important to plants because of their role in gas exchange and photosynthesis. Clear nail polish and clear plastic tape were used to make leaf impressions of A. floridanum. Once impressions were completed‚ compound microscopes were used to count the total number of stomata per slide. The counts of stomata were used to find stomatal densities‚ along with the open/closed ratios of stomata. Stomatal density and open/close ratio of stomata did not differ between the two locations

    1. Define ecology. Identify the two features of organisms studied by ecologists. Ecology is the scientific study of the interactions between organisms and the environment‚ which in turn determine both the distribution of organisms and their abundance. Ecologists study how interactions between organisms and the environment affect phenomena such as the number of species living in a particular area‚ cycling of nutrients in a habitat‚ and the growth of populations. 2. Describe the relationship between
