The cell is the basic structural and functional unit of all forms of life.Every cell consists of cytoplasm enclosed within a membrane; many cells contain organelles, each with a specific function.
Cell biology (also cellular biology or cytology) is a branch of biology that studies the structure, function, and behavior of cells. [1] [2] All living organisms are made of cells.
Basic structure of a peroxisome Distribution of peroxisomes (white) in HEK 293 cells during mitosis Peroxisome in rat neonatal cardiomyocyte. A peroxisome (/ p ə ˈ r ɒ k s ɪ ˌ s oʊ m /) [1] is a membrane-bound organelle, a type of microbody, found in the cytoplasm of virtually all eukaryotic cells.
Cell physiology is the biological study of the activities that take place in a cell to keep it alive. The term physiology refers to normal functions in a living organism. [1] ...
The oral mucosa is the mucous membrane lining the inside of the mouth.It comprises stratified squamous epithelium, termed "oral epithelium", and an underlying connective tissue termed lamina propria. [1]
Cell division in prokaryotes (binary fission) and eukaryotes (mitosis and meiosis).The thick lines are chromosomes, and the thin blue lines are fibers pulling on the chromosomes and pushing the ends of the cell apart.
The corona radiata is the innermost layer of the cells of the cumulus oophorus and is directly adjacent to the zona pellucida, the inner protective glycoprotein layer of the ovum. [1]
PPAR -alpha and -gamma pathways. In the field of molecular biology, the peroxisome proliferator–activated receptors (PPARs) are a group of nuclear receptor proteins that function as transcription factors regulating the expression of genes. [1]
