Eukaryotic cell (Animal Cell)


Cell Theory:All living things are composed of cells. Cells are the basic units of structure and function in all living things. All cells arise from existing cells

ALL ABOUT ANIMAL CELLAn animal cell is classified as a eukaryotic cell and comes in varying sizes. Other eukaryotes include plants, protists, and fungi. Though animals (people) are different from other eukaryoted, our cells are fundamentally similar. Each cell within an animal contains the functional organelles to carry out chemical activities (respiration, metabolism) that help continue the life of the animal (person). The genetic material carries all the necessary coding to continue the life of the species.

Above is a view of an animal cell using a transmission electron microscope

THE MAIN PARTS OF ANIMAL CELLThe organelles form four functional groups:1.) manufacturing - nucleus, ribosomes, rough ER, smooth ER, and golgi apparatus2.) breakdown - lysosomes, peroxisomes, vacuoles3.) energy processing - mitochondria, chloroplasts in plants4.) support, movement, and communication between cells - cell membrane/wall, cell juctions, cytoskeleton, extra cellular matrix.

ORGANELLESNucleus - control center, contains DNACell membrane - semi-permeable, selective with entry and exit of materialsMitochondria - powerhouse, converts chemical energy into ATPRibosomes - create proteins, line membrane of the rough ERGolgi - connected to ER, stores and transports proteinsCytoplasm - jelly-like environment surrounding organellesLysosomes - sacs containing enzymes, breaks down dead organelles, bacteria, and nutrientsRough ER - makes membrane proteins, secretes proteins, and forms transport vesciclesSmooth ER - makes lipids, lysosomes, and transport vescicles

ANIMAL CELL vs PLANT CELLBoth animal cells and plant cells are eukaryotic. There are some differences. Energy is produced in an animal cell by mitochondria. In plants, light energy is converted into usable energy by the chloroplasts. Plants have a rigid cell wall that helps to protect the cell and maintain its shape. Plants cells also have a large vacuole that is usually found in the center of the cell. The vacuole stores water and other nutrients for the plant cell. Similarly, both plant and animal cells contain a golgi, smooth and rough ER, mitochondria, peroxisomes, and nucleus.

Fun Fact: The more active an organism is, the more mitochondria it will need. More activity = Increased need for energy
