Alexa Molinelli BIO 110-14 Exam 5 Homework Chapter # 14 1. What are the five kingdoms and give a brief description of each kingdom? -Monera- single celled prokaryotes; bacteria. Protista- Mostly single celled eukaryotes. Fungi- Multicellular eukaryotes that feed by extracellular digestion and absorption. Plantae- Multicellular photosynthetic autotrophs; producers. Animalia- Diverse multicellular heterotrophs. 2. Who developed the binomial system of nomenclature (genus and species)? -Binomial System

The cell is one of the most basic units of life. There are millions of different types of cells. There are cells that are organisms onto themselves‚ such as microscopic amoeba and bacteria cells. And there are cells that only function when part of a larger organism‚ such as the cells that make up your body. The cell is the smallest unit of life in our bodies. In the body‚ there are brain cells‚ skin cells‚ liver cells‚ stomach cells‚ and the list goes on. All of these cells have unique functions

Observing Cells Objectives: After completing this exercise and reading the corresponding material in your text‚ you should be able to 1. Prepare a wet mount slide 2. Identify structures described in this lab on slides 3. Cite examples of the wide diversity of cell types 4. Relate differences in structure among cells to functional differences Introduction Structurally and functionally‚ all living things share one common feature: all living organisms are composed of cells
Premium Eukaryote Cell Organism
differences are simple; Eukaryotic cells are more complex and have more organelles while Prokaryotic cells are simple and have little organelles. Also‚ Eukaryotes (eukaryotic cells) have one or more cells while Prokaryotes (prokaryotic cells) are only made up of 1 cell. Today‚ I’m going to show a model of a Eukaryotic plant cell model along with

genes being encoded into extra-chromosomal plasmids‚ such activity is typically absent in Eukaryotic cells. 3. The own way DNA is present in each type of cell has different characteristics: Prokaryotes have small‚ efficient amounts of DNA‚ while Eukaryotes contain large and repetitive amounts of the latter. Choose two internal structures of prokaryotic cells and three from eukaryotic cells and describe their function in your own words. Cell Structures Structure Function Plasmid - Prokaryotic

Cell Unit Notes I. Life Processes - What makes something living? A. Biotic: Having life’s conditions Abiotic: Not having life’s conditions Homeostasis: The condition of maintaining a constant internal environment in living organisms. B. Characteristics of living Organisms (LIFE) 1. Nutrition - Food for energy and body (cell) repair and development 2. Transport - Move materials were needed in organism 3. Respiration - Able to generate energy for life processes

Protists are an eclectic group of eukaryotic organisms. Imagine the creatures belonging to the other eukaryotic kingdoms telling protists‚ “You can’t sit at our table‚” so the protists start their own club. Although protists don’t belong to the plant‚ animal‚ or fungi club‚ they still share many characteristics with other eukaryotic life forms. What makes a protists a protists is the fact that it cannot be placed into any of the other kingdoms physically or genetically. For instance‚ the plant-like

A Survey of Eukaryotic Cells and Microorganisms HISTORY OF EUKARYOTES: 1. Evidence indicates that the first Eukaryotic cells first appeared on the earth approximately 2 billion years ago. Fossilized cells appear in shale sediments from China‚ Russia and Australia the date from 850-950 million years ago. 2. Biologists have discovered evidence to suggest that the eukaryotic cell evolved from prokaryotic organisms by a process of intracellular symbiosis. 3. Some of the organelles that
Premium Cell Eukaryote Organelle
7-2 Notes Eukaryotic Cells 1. Eukaryote cells are divided into two parts Nucleus Cytoplasm Portion outside the nucleus where organelles reside Nucleus 2. Contains most of the cell’s DNA 3. DNA is the code for making proteins 4. Surrounded by a double membrane called the nuclear envelope 5. Contains chromatic‚ which consists of DNA bound to protein Condenses during cell division to form chromosomes 6. Nucleolus – small dense region in nucleus where the assembly of ribosomes begins Ribosomes 7. Small

cell is larger and more complex‚ containing many membrane-enclosed organelles. Biological domains further differentiate between kinds of cells. There are three major biological domains‚ two of which are classified for prokaryotes and the other for eukaryotes. They are Domain Bacteria‚ Domain Archaea‚ and Domain Eukarya. Evolution is also a major theme in biology. Evolution is the concept of life evolving over the course of time. Charles Darwin is responsible for the concept of evolution through natural
