it is so important to understand the complexities of cells. There are two basic categories of that all cells fall under. They are prokaryotic cells and eukaryotic cells. Prokaryotic cells are single-celled organisms that include bacteria and archaea. Eukaryotic cells are more complex cells that include protists‚ plants‚ fungi‚ and animals. The major difference of prokaryotic and eukaryotic cells is that prokaryotic cells do not have a nucleus and eukaryotic cells do. Prokaryotic cells are
Premium Bacteria Organism Eukaryote
Prokaryotes were the first cells; bacteria-like organisms • Descendants belong in two groups: Archaea and Eubacteria Symbiogenesis: process whereby cells of one prokaryotic lineage engulfed‚ but did not digest cells from another prokaryotic lineage. The engulfed cell was eventually reduced to an organelle inside the host cell. Eukaryotic products of symbiogenesis include mitochondria and plastids Primary endosymbiosis: development of organelle by prokaryote engulfed and modified the bacteria

Experiment 1 1. For each structure identified‚ do you think its location affects its ability to function? Why or why not? (Hint: those buried deep in the cell probably do different things than those closer to the cell membrane). Structure does not affect function of the cells‚ cells have a particular structure that enables them to carry out their function in the best way. 2. Draw a labeled diagram of a small section of the plasma membrane and briefly describe its structure and function

IRON (METAL) Iron is a chemical element with the symbol Fe (from Latin: ferrum) and atomic number 26. It is a metal in the first transition series. It is the most common element (by mass) forming the planet Earth as a whole‚ forming much of Earth’s outer and inner core. It is the fourth most common element in the Earth’s crust. Iron’s very common presence in rocky planets like Earth is due to its abundant production as a result of fusion in high-mass stars‚ Like other group 8 elements‚ iron

For about 3 billion years‚ all organisms were microscopic‚ and bacteria and archaea were the dominant forms of life. Although bacterial fossils exist‚ their lack of distinctive

Bacteria and archaea are both prokaryotes‚ but they have very different characteristics. How would you compare archaea and bacteria? Archaea cell membrane contains ether linkages cell wall lacks peptidoglycan genes and enzymes behave more like Eukaryotes have three RNA polymerases like eukaryotes extremophiles 4. What process
