differences between prokaryotic and eukaryotic cells. The three differences between prokaryotic and eukaryotic cells are: Eukaryotic cells contain a nucleus inside their cells‚ while prokaryotic cells have genetic material condensed in a nucleoid region. Organelles such as mitochondria‚ Golgi apparatus‚ chloroplast‚ and endoplasmic reticulum are present in eukaryotic cells and prokaryotic don’t have. However‚ the mitochondria and chloroplasts found in eukaryotic cells have larger ribosomes as compared

The autogenic hypothesis of the origin of the eukaryotic cell is that the eukaryotic presxsisted as a prokaryotic cell. 3. What is the evidence that supports the autogenic hypothesis? A process called membrane folding‚ which folded and created the eukaryotic cell ‚ that explains why the different parts of the eurkayotic cell has

DNA |I | |INTRODUCTION | DNA (deoxyribonucleic acid)‚ molecule that acts as the mechanism of biological inheritance in almost all living creatures. DNA is found in nearly all cells and contains the coded instructions that control the workings of the cell. DNA is passed from parents to offspring‚ and contains the coded instructions that enable the offspring to develop from a single cell into an adult body. DNA is the most important molecule in life‚ and an understanding of the

Zoology African Rock Python The African rock python. It is Domain: Eukarya. Domain is the highest taxonomic rank of organisms‚ higher than a kingdom. The African rock python falls under Eukarya because it is a multicellular organism composed of eukaryotic cells. It is Kingdom: Anamalia. Kingdom is the second highest rank. It falls under Anamalia for obvious reasons. It is Phylum: Chordata. Phylum is the primary division of the plant or animal kingdom. It is Class: Reptilia. Class is a group of

many categories that a cell can be classified as. They can be either unicellular‚ being able to function and show all seven characteristics of life with just one cell‚ or multicellular‚ composed of multiple cells that interact with each other. They can also be either prokaryotic‚ without membrane-bound organelles‚ or eukaryotic‚ with membrane-bound organelles. Cells also have many parts that help them to carry out their processes. The cell wall provides structure and defense‚ while the cell membrane
