Ribosomes Function | Their Role in Protein Synthesis

ribosomes function

Ribosomes function is primarily limited to protein synthesis in the cells. But they also act as targets for few drugs in the treatment of diseases. Ribosomes are complex structures having two sub units. One subunit is larger one while the other one is smaller in size. Chemically they are a combination of ribonucleic acid with […]

Importance of Lysosomes | Role in Growth, Disease and Fertilization

Importance of Lysosomes

Importance of lysosomes is not limited to cell death alone. As we know, lysosomes are the cell organelles which act as storehouses of catalytic enzymes. Many hydrolytic lysosomal enzymes enclosed in the membranous organelle. The lysosomes are primarily involved in digestion, cell death, repair, defense and also growth. The hydrolytic enzymes are enclosed inside the […]

Lysosomes | Their Structure, Location and Functions

lysosomes function

Lysosomes are the membrane organelles present in both plant cells and animal cells. They are also present in protozoa but absent in the bacteria. Instead, a periplasmatic space in between cell wall and cell membrane play the role similar to lysosomes. Lysosomes are present near to the cell membrane or even attached it. They have […]

Plant Cell Parts | Their Structure and Functions

plant cell parts

Plant cell parts are almost similar to animal cells with few exceptions and functional differences These plant cells are eukaryotic cells The plant cell is rigid and hard than the animal cells. Further, plant cells are green in color due to the presence of special pigments which aid in photosynthesis. Though there are many similarities, […]

What is a Substrate | Its Role and Examples

what is a substrate

A substrate is substance on which enzymes acts to covert into a product. For many enzymes, there is only one specific substrate. But most enzymes have two or more substrates. A substrate is very specific for an enzyme to catalyze the reaction. It means a substrate can be broken down in presence of that specific […]

Types of chromosomes with their Structures.

Chromosomes are DNA molecules containing part or whole genome of an organism.. They are present in the nucleus of the cell. Chromosomes mostly have two bands separated by a centromere. One can differentiate types of chromosomes based on their morphology, function and other differences. Types of chromosomes Based on the position of the centromere, chromosomes […]

Importance of Pollination | 5 Major benefits in Life

importance of pollination

Pollination is the means of sexual reproduction in plants. Most flowering plants go for sexual reproduction by this method. The plants secrete pollen grains (male gametes) from the anther (male organ). These pollen reach on to the stigma which is a part of female organ in the flower. The pollen then unite with ova to […]

Monomers of DNA and RNA | Their Chemistry & Shape

Monomers of DNA and RNA

Monomers are molecules which can bind to similar molecules to form long chains or polymers. Organic compounds like carbohydrates, amino acids, nucleic acids, etc. can be obtained as monomers. Both DNA and RNA are nucleic acids in all most all the cells. These both molecules are large strands and are made of nuclear bases and […]
