Different types of structures and organelles found in Eukaryotic cells and prokaryotic cells.
|What’s in eukaryotic cells? organelles |What are they used for? |
|Mitochondria |This breaks down food to make energy. |
|Nucleus |This is the brains of the cell. The nucleus tells the brain what to do and |
| |contains chromosomes that are made of DNA. |
|Endoplasmic reticulum |This transports all things like protein around the cell and sometimes out of the |
| |cell. |
|Ribsomes |This is a small cell where proteins are made from amino acids. |
|chloroplast |Found in plants and algae cells where photosynthesis happens. |
|Vacole |This is a large structure found in plant cells that stores water and other |
| |liquids. |
|Cell membrane |This is a barrier between the inside of the cell and the cells environment. |
|Cytoplasm |To hold the structure of the cell and to make sure that it can move freely. |
|Cell wall |This is so that the cell membrane has strength and support. |
|Chloroplast |Uses photosynthesis to create energy. |
|Golgi bodies |These are Saclike structures used for storing and packaging substances made by the|
| |cell that will be transported out of the cell. |
|Lysosomes |These destroy and get rid of all the unwanted stuff inside the cell. |

Eukaryotic

|What’s in prokaryotic cells? organelles |What are they used for? |
|Nucleoid |This is in the centre of the cell where the DNA is. The nucleoid is just |
| |‘imitating the nucleus’. |
|Flagellum | |
|Cell wall |This is just to support the cell. |
|Cell membrane |This is a Phospholipids layer that is a barrier between the inside of the |
| |cell and the cells environment. |
|Ribsomes |Theses make protein by following instructions from the messenger RNA.

Chapter 1: What Is Biology? Essay

NOTES FOR BIOLOGY 1001 SECTION 001 Fall 2012 DR. STEVEN POMARICO, INSTRUCTOR CHAPTER 1 AN INTRODUCTION TO LIFE ON EARTH What is Biology? --- The science of living organisms and life processes. O.K., so what is science? And If biology is the science of “life,” what exactly is life? We all recognize what life is, but it’s difficult to define. The characteristics of life: 1) -Complex, organized structure 2) -Homeostasis - the ability to maintain the structure…

type of microscope would be used in the laboratory to examine the cell size and arrangement within a tissue sample? Please give reasoning behind the answer. Which microscope would be useful when studying the internal structures of a single-celled organism? (2 points) I would use the compound light microscope to examine the cell size and arrangement as the compound light microscope is up to 1000x. This microscope will show the cell size and organization of the tissue sample. To study the internal…

living things: • atoms • atoms replicate(replicator). • First prokaryotic cell( survived in CO2 and water). • Organisms began to use light as an energy source-photosynthesis(oxygen was produced and was toxic). • Oxygen and UV combine to create the ozone layer( the atmosphere was formed). • bacteria and archaea, and eukaryotes combine...endosymbiosis. • Small organelles like mitochondria and chloroplast fuse into larger cells. • plant, animal, fungi lines begin to form • multicellular plants…
