In this article we will discuss about:- 1. Meaning of Lysosomes in Cell 2. Structure of Lysosomes in Cell 3. Function. Meaning of Lysosomes in Cell: Lysosomes are ultra structural particles of the cell containing hydrolytic enzymes responsible for digestion. Though these are common in animal cell, but in plants these are found in the lower groups, such as euglenoids, [...]
The following points highlight the two main types of organellar DNA in cell. The types are: 1. Chloroplast DNA (cp DNA) 2. Mitochondrial DNA (mt DNA). Organellar DNA: Type # 1. Chloroplast DNA (cp DNA): Each chloroplast contains 20-200 copies of a circular double stranded DNA molecule, which may also be linear as found in maize, cp DNA is characterized [...]
In this article we will discuss about:- 1. Evolution of First Cell 2. Origin of Cell Membrane in First Cell 3. Evolution of Metabolism 4. Prokaryotic Cell. Evolution of First Cell: Early living cells were RNA life forms, self- replicating RNA covered by lipoprotein vesicles were the pre-prokaryotes, with time the proteins replaced the catalytic function of RNA, and DNA [...]
