Cells A&P

Cells the building blocks of all living things
What are the 3 main regions of a cell? Nucleus, Plasma Membrane, Cytoplasm
Nucleus control center of a cell
What are the 3 regions of a nucleus? Nuclear Envelope, Nucleoli, Chromatin
Plasma Membrane barrier for cell contents
Microvilli finger-like projections that increase surface area for absorption
What are the 3 membrane junctions? Tight Junctions, Desmosomes, Gap Junctions
Cytoplasm material outside the nucleus and inside the plasma membrane
What are the 3 major elements of cytoplasm? Cytosol, Organelles, Inclusions
Mitochondria "powerhouse" of the cell; supplies most of ATP
Ribosomes sites of protein synthesis
Endoplasmic Reticulum (ER) fluid-filled tubules (cisterns) for carrying substances
What are 2 types of ER? Rough ER, Smooth ER
Golgi Apparatus modifies and packages proteins
What are the different types of packages for Golgi Apparatus? Secretory Vessels, Cell membrane components, Lysosomes
Lysosomes contain enzymes that digest worn-out or non-usable materials
Peroxisomes membraneous sacs of oxidase enzymes
Cytoskeleton network of protein structures
What are the 3 different types of elements of cytoskeleton? Microfilaments, Intermediate, Microtubules
Centrioles direct formation of mitotic spindle
Cilia move materials across cell surface
Flagella propels the cell
Fibroblasts cells that connect body parts
Epithelia Cells cells that covers and lines body organs
Skeletal Muscle Cells cells that move organs and body parts
Fat Cell cells that stores nutrients
Macrophage cells that fights disease
Nerve Cell cells that gathers information and controls body functions
Sperm cells of reproductions
Membrane Transport movement of substances into and out of the cell
What are the 2 basic methods of transport? Passive Transport, Active Transport
What are the 2 types of Passive Transport Processes? Diffusion, Filtration
Diffusion particles tend to distribute themselves evenly
Filtration water and solutes are forced through a membrane by fluid or hydrostatic pressure
What are the 3 types of diffusion? Simple Diffusion, Osmosis, Facilitated Diffusion
What are 2 forms of Active Transport Processes? Solute Pumping, Bulk Transport
Passive Transport Process no energy is required
Active Transport Process (ATP) cell must provide metabolic energy
Name the 2 types of Vesicular Transport Exocytosis, Endocytosis
What are the 2 types of Endocytosis? Phagocytosis, Pinocytosis
What are the 2 major periods of a cell life cycle? Interphase, Cell Division
Name the 2 events of Cell Division Mitosis, Cytokinesis
Mitosis division of the nucleus
Cytokinesis division of the cytoplasm
What are the 4 stages of Mitosis? Prophase, Metaphase, Anaphase, Telophase
