Cells
Organelles-Small part of cell that performs a certain function
Ribosomes
Function: Site of protein synthesis
Structure: Small dense particles free or attached to rough ER
Rough ER(Endoplasmic Reticulum)
Function:Makes proteins and cell's membrane
Structure:Membrane system of sacs and tubules externally studded with Ribosomes
Smooth ER
Function:Site of lipid and steroid hormone synthesis
Structure:Membranous system of sacs and tubules,free of Ribosomed
Golgi Apparatus
Function:Receives,sorts, and re-packages proteins for export from the cell,enlarging the plasma membrane, and lysosome formation
Structure:Close to the ER
Lysosomes
Function:Sites of intracellular digestion
Structure:Filled with enzymes
Mitochondria
Function:Site of ATP synthesis,powerhouse of the cell
Structure:Rodlike, double membrane structures
Peroxisomes
Function:Enzymes detoxify a number of toxic substances
Structure:Bag full of enzymes
Microfilaments
Function:Not permanent,involved in muscle contraction and other types of intracellular movement. Helps cells to change shape of plasma membrane
Structure:Fine filaments of protein actin. Near plasma membrane.
Intermediate filaments
Function:Stable and permanent
Structure:Connected to desmosomes,protein fibers
Microtubules
Function:Not permanent,support the cell and give it shape.
Structure:Cylindrical structures made of tubulin proteins
Centrioles
Function:Involved in the process of Mitosis
Structure:Made up of microtubules
Nucleus
Function:Control center of the cell,responsible for transmitting genetic information and DNA
Strucuture:Nucleolus and nuclear membrane
Nuclear envelope
Function:separates the nucleoplasm from the cytoplasm,regulates passage of substances to and from the nucleus
Structure:Double membraned structure
Nucleoli
Function:Site of Ribosome
Structure:Dense spherical(non-membrane-bounded) bodies
Chromatin
Function:DNA constitutes the genes
Structure:Granular material composed of DNA
Endocytosis(in the cell)
Pinocystosis(drinking cell)
non-selective and does not require protein
Vescile is formed in plasma membrane
Receptor mediated endocytosis
Requires protein and is selective
Phagocytosis(eating cell)
large movement of cell to engulf a dying cell
Nucleus
Control Center
Plasma Membrane
Barrier to protect
Cytoplasm
Most cellular activities occur here
Exocytosis
Sending something out like goblet cells
