Microbiology

Any organism having as its fundamental structural unit a cell type that contains specialized organelles in the cytoplasm, a membrane-bound nucleus enclosing genetic material organized into chromosomes, and an elaborate syst of division by mytosis or meiosis, characteristic of all life forms except bacteria, blue-green algae, and other primitive organisms.

1. Nuclei: DNA containing-defining characteristic of eukaryote

2. Mitochondria: Energy production

3. Endoplasmic reticulum: Translation of proteins

4. Golgi apparatus: package materials for secretion

5. vacuoles: food or other storage

info

Do not have organelles

- employ active transport across the cytoplasmic membrane

- have an additional type of transport called "bulk transport"

a cell wants to engulf a large molecule (endocytosis) or secrete whole antibody molecules (exocytosis), it can do so by the creation of a vesicle.

-cell receptor binds to a ligand. The cell membrane then invaginates into the cell and pinches off to form vesicle

-opposite process of endocytosis

- digestive organelle

- similar to each other in cross-section, but flagella are much longer than cilia

- has a nuclei

- a long lashlike appendage serving as an organ of locomotion in protozoa

(sperm cells)

- hairlike orgonelles, identical to flagella, that line the surfaces in certain cells and beat in rhythm waves, providing locomotion and moving liquids along internal epithelial tissue in animals.
