HalimaAbdiCells
Consists of:
Nucleus: Control Center of the cell; Transmitting genetic information
Nuclear envelope
Control center of cell
Nucleoli
Site of ribosome subunit
Chromatin
DNA constitutes the gene
Cytoplasm: fluid material that fills the cell. Responsible for giving cell its shape
Mitochondria
Site of ATP synthesis
Golgi apparatus
Proteins for secretion from the cell
Lysosomes
Sites of intracellular digestion
Smooth endoplasmic reticulum
Site of lipid and steroid hormone synthesis
Ribosomes
The site of protein synthesis
Rough endoplasmic reticulum
Makes proteins that are secreted from the cell
Cytoskeleton
Support material within cell, maintain shape of cell
Peroxisomes
Remove toxic waste
Microfilaments
Support and give cell shape
Intermediate filaments
Provide mechanical support and resist tension
Microtubles
Support and give cell its shape, involved in cellular/intraceullar movements
Centrioles
Organization of microtubule network during mitosis
Plasma Membrane: Serves as an external cell barrier; transports substances into or out of the cell
Membrane Transport
Simple Diffusion: Small, uncharged molecules pass freely
Osmosis: Water molecules across a membrane
Facilitated diffusion: Moving down a concentration gradient
Endocytosis:Large particles and macromolecules enter the cell
Phagocytosis:"Cell eating". Cell engulfs large particle, functions as protection.
Pinocytosis:"Cell drinking".Function in nutrient absorbtion
Receptor-mediated endocytosis: Bind to specific receptors on the cell, function as a target
Exocytosis: Substances move outside of cell via secretory vesicles
