Organelles in Eukaryotic Cells

Many organells exist in a cell — often more in Eukaryotic cells — that help execute the cell's functions. They serve a variety of purposes, and help form the basics of cellular systems. Categorizing them based on whether or not they have membranes KBhBIO101OrganellsBasedOnMembranes

• Chloroplast — found in plants + does photosynthesis
• Mitochondria — found in animals + store ATP and extract energy from ATP

• Rough ER — covered by ribosomes and folds KBhBIO101Proteins proteins
• Smooth ER — not covered by ribosomes and makes KBhBIO101Lipids lipids

• Ribosomes => synthesizes proteins
• Golgi apparatus => packs, modifying, and moving proteins

• Cell Wall — found in plants => surround the cell: hard
• Plasma membrane — found in animals => surround the cell: soft KBhBIO101Lipids lipids

• Cytosol => liquid found inside cells; the "cytoplasm" floats within it
• Cytoplasm => all the stuff within the cell

• Nucleus => centre of the cell, stores DNA
• Nucleolus => largest part of the nucleous that makes ribosomes

• Lysosomes => vesticles that contains enzymes that breaks down biomolecules
• Food Vacoules => vesticels that stores food and other resources

• Cytoskeleton => complex network of proteins + fibres that organize the rest of the cell
• Microtubulues => Polymers of tubulin protein that provides the main structure of eukarotic cells

• Flagella => a bacteria's tail — allow them to move and also act as an sensory organ. longer than a cilla, and moves in sinosoidial pattern.
• Cilium => a cell's "hair" — provides sensory and communications functions. Motil cilla could move about to "grab" things, and non-motile cilla can't move. more abundant that the flagella, and moves in circular pattern if they do move, and moves in circular pattern if they do move
