Animal cells Flashcards
mitochondria - structure
plant and animal cell
- double membrane
mitochondria - function
plant and animal cell
- aerobic resperation
- forms ATP
- ATP used as a source of energy for: growth, cell division, metabolic reactions ect.
Rough Endoplasmic Reticulum (RER) - Structure
plant and animal cell
- composed of cisternae covered in ribosomes
Rough Endoplasmic Reticulum (RER) - function
plant and animal cell
- synthesis of protines
- packages proteins into vesicles and transports them to other parts of the cell - eg Golgi apparatus
80s Ribosomes - function
plant and animal cell
- where amino acids are bonded together to form proteins - protein synthesis
centrioles - structure
plant and animal cell
- small tubes of protein fibers
Centrioles - function
plant and animal cell
- form spindle fibers in cell division
Golgi apparatus/body- structure
plant and animal cell
- stack of membrane bound flattened sacs
Golgi apparatus/body- function
plant and animal cell
- modifies the proteins and packages them into vesicles to be transported
plasma Membrane- structure
plant and animal cell
- phospholipid bilayer with embedded proteins
Plasma Membrane- function
plant and animal cell
- partially permeable and regulates transport in and out of cells
- separates cell contense from outside environment
Smooth Endoplasmic Reticulum (SER) - structure
plant and animal cell
- composed of cisternae
Smooth Endoplasmic Reticulum (SER) - function
plant and animal cell
- Makes: steroid hormones
- regulates: calcium ion concentration
- processes + metabolizes: toxins/ drugs/ alcohol in liver cells
Nucleolus - structure
plant and animal cell
- inside the nucleus
Neucleolus - function
plant and animal cell
- makes RNA + ribosomes
Vesicles - structure
plant and animal cell
- small spherical membrane bound sacs
Lysosomes - structure
plant and animal cell
- contain hydrolytic enxymes in membrane bound sac
Vesicles - function
plant and animal cell
Transport: transport molecules inside the cell - eg from RER to Golgi body
Secretory: transport proteins to cell surface membrane for release outside of cell via exocytosis
Lysosomes - function
plant and animal cell
- hydrolytic enzymes digest antigens, bacteria, viruses, pathogens ect
- brake down worn out cell components/waste products
