Which organelle possess hydrolase enzyme ?
Lysosomes are membrane-bound organelles that contain a variety of enzymes, including hydrolases. These enzymes are responsible for breaking down various biomolecules and cellular debris. Lysosomes play a crucial role in the cell's waste disposal and recycling processes.
The leucoplast which stores protein is known as
Leucoplasts are a type of plastid found in plant cells that are primarily involved in the storage of nutrients. Aleuroplasts are a specific type of leucoplast that store proteins. They are found in seeds and other storage organs of plants.
The protoplast surrounding the centriole is called as
The centrosphere, also known as the pericentriolar material, is the region of the cytoplasm that surrounds the centriole. It is involved in the organization of microtubules and plays a key role during cell division by helping to form the mitotic spindle.
Like zygote any cell of the body is capable of producing a new individual is known as
Totipotency is the ability of a single cell to divide and produce all the differentiated cells in an organism, including both the somatic and germ cells. This is the characteristic feature of a zygote, which is the most potent cell, capable of giving rise to a complete organism.
Which organelle is associated in the formation of basal granules, cilia, and flagella ?
The centrosome is an organelle that serves as the main microtubule organizing center of the animal cell as well as a regulator of cell-cycle progression. Centrosomes are crucial for the formation of basal granules, cilia, and flagella.
How many basic shapes of Bacteria are there?
There are four basic shapes of bacteria: cocci (spherical), bacilli (rod-shaped), spirilla (spiral-shaped), and vibrios (comma-shaped). These shapes help in identifying and classifying different bacterial species.
Which structure aerves as a protective layer against attack by phagocytes and by viruses ?
The capsule serves as a protective layer for bacterial cells against attacks by phagocytes and viruses. It is a gelatinous outer layer that surrounds the cell wall of some bacteria, providing an additional defense mechanism.
Which organelle possesses circular DNA ?
Chloroplasts possess circular DNA. Like mitochondria, chloroplasts are thought to have originated from free-living prokaryotes that were taken up by a host cell. This endosymbiotic theory explains why chloroplasts have their own circular DNA, similar to bacterial DNA.
Assertion (A) and Reason (R) type questions A: Animal cell possesses centriole R: Some algae also possesses centriole
Assertion (A) and Reason (R) both are true, but reason (R) is not a correct explanation of the assertion (A). Animal cells do possess centrioles, and some algae also have centrioles, but the presence of centrioles in algae does not explain why animal cells have centrioles.
The protoplast surrounding the centriole is called as
The protoplasmic region surrounding the centriole is called the centrosphere. It is a specialized region that plays a crucial role in cell division and the organization of microtubules in the cell.
