The eukaryotic cells are found in most of the algae, fungi, protozoa and all the higher plants and animals. Irrespective of their variable shapes and sizes, these cells display the following fundamental components (Fig 1.15): 1. Cell wall and Plasmalemma or cytoplasmic membrane, 2. Cytoplasm and 3. Nucleus. The eukaryotic cells contain extensive internal membrane systems such as endoplasmic reticulum [...]
In this article we will discuss about the cell wall and its structure. In plants a cell is always bounded by a wall known as cell wall. It is primarily composed of cellulose. There are also hemicellulose, pectin, lignin, cutin and mineral deposits involved in building up of the cell wall at different stages of development. The cell wall of [...]
The upcoming discussion will update you about the difference between prokaryotic and eukaryotic cells. Difference # Prokaryotic Cell: 1. Nuclear membrane is absent in prokaryotic cell. 2. Chromosomes are single in prokaryotic cell. 3. DNA is naked. 4. Nucleolus is absent in prokaryotic cell. 5. Mitochondria is absent. Respiratory and photosynthetic enzymes present in plasma-membrane. 6. Endoplasmic reticulum is absent [...]
