Plasma membrane, Cytoplasm, Nucleus, Nucleolus, ER Smooth (ER = endoplasmic reticulum), ER Rough, Golgi, Vesicle, 80s Ribosomes, Mitochondrion, Centriole and the Cytoskeleton-microtubule.
Structure and function of the plasma membrane in a eukaryotic animal cell:
Structure -> Is selectively permeable, forms a double layer of lipids. Proteins embed into the layer.
Functions -> Helps to maintain the shape & structure. Controls what enters and leaves the cell. Takes in the nutrients and excretes waste products. It sends and receives chemical & electrical messages.
Structure and functions of the Cytoplasm in the eukaryotic animal cell:
Structure -> Is a thick jelly-like, semi-transparent fluid. Occupies the region between the membrane & nucleus.
Functions -> maintains cell shape, and stores chemicals for metabolic reactions.
Structure and function of the nucleus in the eukaryotic animal cell:
Structure -> It is the largest, nuclear envelope and contains nuclear pores that contain genetic material and the nucleolus.
Functions -> Controls / regulates the cellular activity inside the animal cell. Stores DNA & proteins.
Structure and Functions of the nucleolus of a eukaryotic animal cell:
Structure -> A dense spherical structure.
Functions -> Makes RNA and ribosomes.
Structure and function of the Smooth Endoplasmic Reticulum in a eukaryotic animal cell:
Structure -> A network of membrane bound flattened sacs of cisternae. Does not contain ribosomes.
Function -> The synthesis of lipids and carbohydrates occurs here. Transports lipids and carbohydrates.
Structure and function of the Rough Endoplasmic Reticulum in a eukaryotic animal cell:
Structure -> A network of membrane bound flattened sacs of cisternae. The cisternae have ribosomes.
Functions -> Where protein synthesis occurs. Transports of newly synthesised proteins to the Golgi.
Structure and function of the Golgi apparatus in a eukaryotic animal cell:
Structure -> Stack of membrane bound flattened sacs.
Functions -> Receives new proteins from the rough ER. Modifies & packages proteins into the vesicles. These proteins are moved into vesicles.
Structure and function of the Vesicle in the eukaryotic animal cell:
Structure -> small spherical membrane bound sacs with fluid.
Functions -> Transports material inside the cell. Secretory vesicles transports proteins that are to be released from the cell to the cells surface membrane.
Structure and function of the lysosome in the eukaryotic animal cell:
Structure -> Small spherical membrane bound sacs that contain hydrolytic enzymes.
Functions -> break down waste material including old organelles.
Structure and functions of the 80s Ribosome in a eukaryotic animal cell:
Structure -> Tiny organelles attached to the rough ER, can float freely. It contains 2 sub units, the 60s and 40s, it has no membrane.
Function -> Protein synthesis occurs here.
Structure and Functions of the mitochondria in a eukaryotic animal cell:
Structure -> has 2 membranes, the inner membrane is highly folded to form cristae, the central membrane is the matrix and can be seen as long in shape or spherical depending on angle.
Functions -> Cellular respiration occurs here, provides energy like ATP, sugars and fatty acids.
Structure and functions of the Centriole in a eukaryotic animal cell:
Structure -> A small tubule of protein fibre, contains hydrolyte enzymes.
Functions -> Forms spindle fibres during cell division.
