No, bacteria do not contain mitochondria. Being prokaryotic they do not possess any membrane-bound organelles. In fact, mitochondria are thought... View Article
Yes, sperms contain mitochondria in the middle piece. It is required to provide energy for sperm movement. Further reading: Significance of... View Article
Yes, both plants and animal cells produce ATPs in mitochondria during cellular respiration. Living organisms derive energy from the oxidation of... View Article
Glucose undergoes partial oxidation to form two molecules of pyruvate in the cytosol by glycolysis. Pyruvate is then transported to the... View Article
Yes, mitochondria produce ATP. They are known as the powerhouse of the eukaryotic cell. The inner mitochondrial membrane consists of the electron... View Article
Yes, mitochondria have a double membrane system. They possess an outer membrane, inner membrane and intermembrane space between them. The inner... View Article
The human egg contains the most number of mitochondria. It contains around 100,000 - 600,000 mitochondria. Mitochondrial DNA is inherited from... View Article
Most of the eukaryotic cells have mitochondria. Mitochondria are known as the powerhouse of the cell. The main function of mitochondria is to... View Article
Without mitochondria, a eukaryotic cell has to depend on anaerobic respiration for energy. It is much less compared to aerobic respiration. In... View Article
No, mitochondria can not live independently. Although they are thought to be evolved from endosymbiont bacteria, they can no longer live... View Article
Spallanzani first observed star-shaped vacuoles in protozoa. Later Dujardin named these star-shaped organelles as vacuoles. Further reading:... View Article
In salt water, the solute concentration outside the cell is more than inside the cell so the water flows out of the cell down the concentration... View Article
Amoeba need contractile vacuoles for osmoregulation. It prevents the cell from retaining excess water. If the cell absorbs too much water, it can... View Article
Plant cells need both chloroplasts and mitochondria because they perform both photosynthesis and cell respiration. Chloroplast converts light... View Article
Plants keep their stomata closed at night, to prevent or to control the excess loss of water from their pores. Stomata are the specialized tiny... View Article
Plasmolysis does not occur in dead plants, because it is the process of loss of water in the cell cause due to the contraction or shrinkage of... View Article
Ribosomes are the only cell organelle, involved in the synthesis of protein. Therefore, they are called the protein factory of the cell.... View Article
The catabolism process refers to the set of metabolic pathways, which includes the breaks down larger molecules into smaller units to release... View Article
An amphibolic pathway mainly refers to the pathway which includes both anabolic and catabolic processes. Respiration is called as an amphibolic... View Article
