what does the cell envelope of a prokaryotic cell consist of? it consists of a capsule, cell wall, cytoplasm, plasma membrane, cytoplasm region or nucleiod region, ribosome, plasmids, pili and flagella
what is a cell? cells can be defined as the basic unit of life
where does the term 'cell' come from? the term cell is derived from a latin word 'cella' which means "small room"
what are prokaryotic cells? they are a cells that lack a nuclear membrane and most components of eukaryotic cells
who was the first to observe cells? a scientist called Robert Hook in 1665
where does the term prokaryotes come from? the term prokaryotes come from the greek word "prokaryote" which mean before nuclei
Do prokaryotes contain a membrane bonded organelle? no
Are prokaryotic cells unicellular or multicellular? unicellular
How do prokaryotic cells reproduce? they reproduce through binary fission, in some cases, few prokaryotic organisms can reproduce through budding
Do prokaryotic cells have a cell envelope? yes
how does cell division happen in prokaryotes? through binary fision
what is a capsule? it is a slime layer which covers the cell wall of the prokaryote.
what is the function of the capsule? it is used to stick cells together. it also works as a food reserve. It also protects the cell from dryness
what is the capsule composed of? it is composed of a thick polysaccharides
what is prokaryotic cell wall? cell wall is a tough and rigid layer that surrounds prokaryotic cells (and plant cell but never animal cells).
what is the function of the cell wall? it provides strength and rigidity to the cell
what is the composition of cell wall? it is composed of glycoprotein murein
what is the cytoplasm? it is the fluid that fills the cell
what is the function of the cytoplasm? it is important in cellular growth, metabolism and replication
what is plasma membrane? also known as cell membrane, it surrounds the cell and is important in controlling the movement of substances in and out of the cell
what is plasma membrane composed of? it is composed of proteins, phospholipids and carbohydrates which forms a fluid mosaic
what is a flagella? it is the rotating tail
what powers the flagella? the flagella is powered by H+ gradient across the cell membrane
what is a pili? they are small protein appendage that attaches the bacteria to a surface
what are pili used for? they are used in conjugation to exchange the genetic information
what is a mesosome? they are folds that are present inside the plasma membrane
what is the function of mesosome? they important in cellular respiration, replication of DNA, cell division
