|
what is the nucleus? |
the nucleus is the control centre of the cell, it contains RNA (ribonucleic acid), enzymes, and chromosomes. It is a membrane surrounded structure |
|
|
ribosomes |
ribosomes are tiny particles made up of RNA and proteins, these may be attached to the rough endoplastic reticulum or float freely in the cytoplasm |
|
|
the vacuole |
the animal vacuole is a storage centre in the cytoplasm, it is a sac in which food, water, and waste is stored |
|
|
plasma/'cell' membrane |
plasma membrane is composed of a lipid bilayer that functions in protection, secretion, sensitivity, and support
|
|
|
the nuclear membrane |
the nuclear membrane protects the nucleus, it is porous and its porosity allows materials to pass in and out of the nucleus |
|
|
organelles |
an organelle is a tiny cell structure, organelles function cooperatively in many different ways to allow the cells and tissues to perform their unique functions |
|
|
Golgi body/apparatus |
these are flattened stacks of membranes that modify and package proteins and lipids for intra and extracellular use, the Golgi apparatus takes materials through the endoplastic reticulum and sends them to other parts |
|
|
lysosomes |
these are small vesicles which contain digestive enzymes for breaking down food and waste cell parts |
|
|
cytoplasm |
this is situated between the cell membrane and the nucleus, it is the aqueous matrix of the cell outside the nucleus, and many different organisms are found here |
|
|
endoplastic reticulum; rough and smooth |
the endoplastic reticulum (ER) is a membranous network within the cytoplasm, the rough ER is studded with ribosomes for protein synthesis |
|
|
mitochondria |
mitochondria produces ATP (adenosine triphosphate) via oxidative phosphorylation for energy |
|
|
cell inclusions |
cell inclusions are non-living materials in the protoplasm of a cell. These are often temporary constituents and are not surrounded with membrane, unlike organelles
|
|
|
centrioles |
centrioles are paired inclusions which are essential for chromosome movement in cell division |
|
|
nucleolus |
the nucleolus is made up of RNA and proteins within the nucleus. The nucleolus makes ribosomes, which go on to make proteins. The nucleolus disappears when the cell divides |
|
|
microfilaments |
microfilaments are tiny inclusions that provide strength and support for the cell |
|
|
microtubules |
microtubules are inclusions that make up the cytoskeleton and assist in transport within the cell (intracellular) |
|
|
vesicle |
a vesicle is a small structure within a cell, consisting of fluid enclosed by a lipid bilayer |
