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 plant, protist, and fungi. Though animals (people) are different from other eukaryotes, 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 blueprint or DNA has coding for every protein a single eukaryote would need to survive.

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 - mitochondria4.) support, movement, and communiction between cells - cell wall, cell junctions, cytoskeleton, and extracellular 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 rough ERSmooth ER - creates, transports lipids and proteinsRough ER - creates, transports, modifies proteins and lipidsGolgi - connected to ER, stores and transports proteinsCytoplasm - jelly-like environment surrounding organellesLysosome - sacs containing enzymes, breaks down dead organelles, bacteria, and nutrients

ANIMAL CELL vs PLANT CELLBoth plant cells and animal cells are eukaryotic. There are some differences. Energy is produced in an animal cell by the mitochondria. In plants, light energy is converted into usable energy by the chloroplasts. Plants have a rigid cell wall that help protect the cell and maintain its shape. Plant 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 animal and plant cells contain a nucleus, golgi, smooth and rough ER, ribosomes, and mitochondrion.

FUN FACT: The more active an organism is, the more mitochondria it will need. More active = Increased need of energy
