Types of Cells – Prokaryotic and Eukaryotic Cells Explained
Biologists classify cellular life into two broad cell types: prokaryotic cells and eukaryotic cells. Prokaryotic cells lack a membrane-bound nucleus, whereas eukaryotic cells contain a nucleus and extensive membrane-bound compartments. Bacteria and archaea are prokaryotic, while animals, plants, fungi, and diverse microbial eukaryotes have eukaryotic cells. What Are the Two Basic Types of Cells? Biologists … Read more

Plasmolysis – Definition, Process, Types, Stages and Examples
Plasmolysis is a process in which the protoplast of a plant cell shrinks away from the cell wall because of loss of water from the cell. It occurs when a living plant cell is placed in a hypertonic solution having lower water potential than that of the cell. During this process, water moves out from … Read more
