prokaryotes are microscopic single-celled organisms. E.g.: Bacteria. Eukaryotic Cells: Is type of cells that Have a nucleus and other membrane bound Organelles‚ The nucleus is the largest organelle where it encloses the genetic information (DNA)‚ Eukaryotes may be Multi-cellular

are the smallest unit of life and are often called the "building blocks of life". The distinction between prokaryotes and eukaryotes is considered to be the most important variation among groups of organisms. Eukaryotic cells contain membrane-bound organelles‚ such as the nucleus‚ while prokaryotic cells do not. The differences in cellular structure of prokaryotes and eukaryotes include the presence of mitochondria and chloroplasts‚ the cell wall‚ and the structure of chromosomal DNA. In this lab four

time Two Kingdom classification (Kingdom Plantae & Kingdom Animalia) was developed. Drawbacks of 2-kingdom classification Prokaryotes (Bacteria‚ cyanobacteria) and eukaryotes (fungi‚ mosses‚ ferns‚ gymnosperms and angiosperms) were included under ‘Plants’. It is based on the presence of cell wall. But prokaryotes and eukaryotes are widely differed in other characteristics. It included the unicellular and the multicellular organisms in same group. E.g. Chlamydomonas and Spirogyra were placed

below the characteristics that apply to diatoms‚ dinoflagellates and the characteristics they share Characteristics of Diatoms Similarities Between Diatoms and Dinoflagellates Characteristics of Dinoflagellates Diatoms are single cellular eukaryotes that are super tiny in size. They are pretty much like photosynthetic micro-organisms‚ some live simple or branched and others are filamentous and others are in a gelatinous envelope or tube. All diatoms are enclosed by something that is called

Microscopy‚ Cell Structure and Function Task 2 I: Name and describe the four main types of tissues in animals stating their functions and their location in the body give two examples of each type. The four main types of tissues that you will find in eukaryotes are connective‚ muscle‚ nervous and epithelial tissues; each of which having very different roles. Connective Tissue The first tissue type I am going to look at is the connective tissue. This tissue is found all over the body‚ including the central

Why is this? if the vacuole is empty the plant will because the water and the plant. 6) Name an organelle that you see in the plant cell that you did not see in the animal cell. Eukaryote 7) Why do you think an animal cell does not have the part that you name in #6? Because Animals get the energy from food because plants get energy from the sun. http://www.cellsalive.com/cells/cell_model.htm and go to “Plant Cell”

The social amoeba Dictyostelium discoideum is an interesting microbe that has used as a powerful model organism for biomedical and pharmacological studies. This eukaryote model‚ which has been used to study basic cell function and multicellular development‚ undergoes a 24-h asexual life cycle comprised of both single-cell and multicellular phases. As a result‚ it is an excellent system for studying a variety of cellular and developmental processes such as‚ chemotaxsis‚ lysosome function and signaling
