consisting of organisms that alter their body shape and that move about and acquire food either by means of pseudopodia or by protoplasmic flow without producing discrete pseudopodia. Phylum Sarcodina The sarcodines are a much more familiar group of protists than the mastigophores. | The most well-known example of a sarcodine is the famous amoeba. Lacking any rigid structure outside of their cell membrane‚ sarcodines can freely change their shape and form pseudopodia. Sarcodines can live in both

Ex: zooflagelletes Animal-like protists -heterotrophs that capture and ingest food. Ex: amoeba. Plant like protists -autotrophs that make their own food. Ex: algae. 2.3 Fungi -fungi are heterotrophic

Viruses are tiny particles of DNA that have the potential to make people and animals extremely sick. It is ironic that viruses are very powerful‚ yet cannot reproduce by itself. They have various shapes‚ including rod-like‚ spherical‚ and phage. They generally have a similar structure: a protein coat called a capsid‚ a small amount of nucleic acid (DNA or RNA) that is located within the capsid. Important characteristics include: not living and no respiration. They can only reproduce within a host

The collared lizard is a species found in the Desert Southwest. Male collared lizards show considerable color variation‚ ranging from brightly colored to a very dull pattern. The goal is to determine the function‚ if any‚ of male color patterns in collared lizards‚ using the scientific method. The tentative explanation is that male color

The ova is the female gamete produced by the female reproductive system and joins together with the sperm‚ the male gamete‚ during fertilization to form the embryo. Gametes are haploids which is the only type of cell that contains only one set of chromosomes. Ova are produced by many living organisms‚ such as animals‚ protists‚ fungi‚ and flowering plants and ferns. In animals‚ they are
