in prokaryotes means that they are structurally less complex than eukaryotes. B) The lack of internal membranes means that prokaryotes cannot compartmentalize function to the same extent as eukaryotes. C) All membrane function in prokaryotes is accomplished in the plasma membrane‚ while in eukaryotes‚ these functions are more distributed among the organelles. D) The specialization of function in organelles suggests that eukaryotes will contain a wider variety of phospholipids than prokaryotes.

CELL * The prokaryotes (pron.: /‚ pro-KAH-ree-otes ) are a group of organisms whose cells lack a cell nucleus (karyon). * The organisms whose cells do have a nucleus are called eukaryotes. (Eu=true‚ karyon= nucleus) * A tissue is an ensemble of similar cells from the same origin that together carry out a specific function. * Organs are then formed by the functional grouping together of multiple tissues.

Bonus Assignment: Protist & Fungi 1.Complete Chapter 21.1 Assessment‚ page 605‚ numbers 1-3. 1. a. Protist- a protest is a eukaryote that is not a member of the plant‚ animal‚ or fungi kingdom b. compare the updated classification of protists with the older one. Recently the protest kingdom has been divided into six major clades. These new found clades relate some of the protists to animals and fungi. 2.What are the four major ways protists can move? Provide an explanation for each. How

2. Biological Classification Classification The process of grouping living organisms into convenient categories based on simple characters is known as classification. 1. Two kingdom classification Carolus Linnaeus divided all living things into two kingdoms- Plantae and Animalia. 2. Five kingdom classification R.H. Whittaker divided all living things into five kingdoms- Monera‚ Protista‚ Fungi‚ Plantae‚ and Animalia. The main criteria for classification included o cell structure o thallus

Prokaryotic cells are single celled organisms that were formed at the formation of the earth‚ so are the most basic life forms. The prokaryotes are organised in the ‘three domain system’ and include bacteria and blue-green algae. Prokaryotes live in many environments including extreme habitats such as hydrothermal vents‚ hot springs‚ swamps‚ wetlands‚ and the guts of animals. This is a diagram of a prokaryote cell and it shows that they are not very complex cells. They do not contain any membrane

Course Description This course applies a broad‚ conceptual understanding of biology. Students are introduced to scientific ideologies and concepts that not only shape the biological world‚ but also shape humans. Students examine the scientific method‚ evolution and biodiversity‚ the biology of cells‚ physiology‚ the dynamics of inheritance‚ and the effect humans have on the environment. The text emphasizes methods and the theoretical foundations of ideas‚ while minimizing isolated facts. It stresses

In the bacterium‚ the chromosome consists of a single naked circle of DNA. In eukaryotes‚ each chromosome consists of a single linear DNA molecule and associated proteins. The chromosomes contain hereditary information used to direct synthesis of proteins. Similarities needed in
