Solution
Organelle simply means “tiny organs”. As the body is made up of different organs, the cell also has “small organs” that perform special functions. In general, they are membrane bounded compartments or cell structures. In strict description, the organelle is a membrane bounded compartment or a cell structure that performs a special purpose. In a less stringent definition, the organelle refers to any cellular structure, whether or not a membrane bounded structure carries a particular purpose.
Complete step by step answer:
The eukaryotic cell comprises several organelles, such as the nucleus, the endoplasmic reticulum, the Golgi apparatus, the mitochondria and the chloroplast (plastids) . However, not all of these organelles are present in a single cell or in an organism. Thylakoids are membrane bounded compartments inside chloroplast and cyanobacteria. They are the site of light dependent reaction of photosynthesis. Cristae is a folding in the inner membrane of mitochondria its name is taken from the Latin word which means correct or flume, and it gives the inner membrane its characteristic wrinkled shape providing a large surface area for the chemical reactions. Cisternae is a flattened membrane disc of Endoplasmic Reticulum and Golgi apparatus. Chromatin is a structure made up of DNA and protein which after condensation forms chromosomes, which is a genetic material of cells. The DNA carries the cells genetic instructions.
Thus, the answer is option:C-A-3, B-4, C-1, D-2
Note:
Thylakoid consists of a thylakoid membrane surrounding a thylakoid lumen. Chloroplast thylakoid frequently refers to as grana. Golgi cisternae can be separated into four classes such as medical, trans, and TGN.
