Mahshid Fathi- May 27/2011. 1. Outline. Objectives. Introduction. Eubacteria & . Archarbacteria. Prokaryotes. Unicellular organisms that lack a nucleus. Prokaryotes are identified by characteristics such as shape, the chemical nature of their cell walls, the way they move, and the way they obtain energy.. Homeotic Genes. Type of master gene that controls formation of specific body parts during development. Antennapedia. . Expressed in the thorax causes legs to form. Expressed in the head causes legs to form there also. Cell Theory. Every living organism consists of one or more cells.. The cell is the structural and functional unit of life.. All living cells arise by division of preexisting cells.. Cells contain hereditary material, which they pass on to their offspring during division.. Structure & Function. Dr.Qurat-Ul-Ain.

Single-celled organisms. Very tiny. Cannot be seen without a microscope. Our microscopes are not powerful enough. Lack a nucleus and most other organelles. Most numerous organisms on Earth. Extremely important organisms.. Biology Unit 04 Lesson 01. Prokaryotes – What are they?. Cells (usually single-celled) with no nucleus. Have no specialized organelles. Usually have: cell wall, cell membrane, ribosomes, genetic material, cytoplasm, and flagella or cilia. GET READY TO USE THEM. STAND UP NOW . WITH CLICKERS IN HAND. WHEN I GIVE THE SIGNAL,.

Principles of microbial cell structure . Elements of Microbial cell Structure. Eukaryotes. . Prokaryotes & chemistry of cellular components . Classifying Prokaryotes. The smallest and most abundant microorganisms on Earth are . prokaryotes. —unicellular organisms that lack a nucleus. . Prokaryotes have DNA, like all other cells, but their DNA is not found in a membrane-bound nuclear envelope as it is in eukaryotes. Prokaryote DNA is located in the cytoplasm. .
