Digestive Function in Lysosomes (With Diagram)

The following points highlight the top four types of digestive function in lysosomes. The types are: 1. Degradation of Foreign Matter Introduced into the Cell 2. Destruction of Defective Cellular Organelles 3. Complete Destruction of Cell 4. Hydrolytic Enzymes. Digestive Function: Type # 1.  Degradation of Foreign Matter Introduced into the Cell: Foreign materials are introduced within the cell by [...]

Ribosomes: Chemical Composition and Structure | Cytoplasm

In this article we will discuss about the chemical composition and structure of ribosomes. Chemical Composition of Ribosomes: Ribosomes are made of RNA and protein. In E. coli, they contain 34% protein and 66% RNA, while in eukaryotes, they contain 40% protein and 60% RNA. Chemical composition of large subunit is different from that of small subunit. The size and [...]

Chloroplasts: Ultrastructure and Functions | Cytoplasm

In this article we will discuss about the ultrastructure and functions of chloroplasts in the cytoplasm. Ultrastructure of Chloroplast: Chloroplasts of higher plants have disc-shaped or oval structure, 10 µm in length and 2-4 µm in diameter. Algal species contain larger chloroplasts of different shapes, e.g., spiral, cup-shaped, circular bands. The number of chloroplasts per cell is one to two [...]
