The underlined words are defined as follows:
Cisterna is a flattened membrane disk that makes up the Golgi apparatus. They carry Golgi enzymes to help or modify the cargo proteins. They also carry structural proteins essential for their maintenance as flattened membranes. The flattened regions of the rough endoplasmic reticulum are also cisternae.
Glyoxysomes are specialized peroxisomes. They are found in plants, especially in the fat storage tissues of germinating seeds. They are also found in filamentous fungi. Just similar to all peroxisomes, in glyoxysomes also the fatty acids are hydrolyzed to acetyl-CoA by the peroxisomal -oxidation enzymes.
Nucleoid means nucleus-like. It is an irregularly-shaped region within a prokaryotic cell containing all or most of the genetic material.
The membranes present within a cell membrane/cytoplasmic membrane are called endomembranes. These membranes divide the cell into functional and structural compartments, or organelles. Examples for endomembrane system: nuclear envelope, vesicles, Golgi apparatus, endosomes, and other membranous organelles.
Fibronectin is a high-molecular weight glycoprotein of the extracellular matrix. It binds to membrane-spanning receptor proteins called integrins.
Glycocalyx is a glycoprotein-polysaccharide covering and it surrounds many cells. It is clearly observed in biofilms.
Integrins are transmembrane receptors that act as bridges for cell-cell and cell-extracellular matrix (ECM) interactions.
