Which of the following bacterial genera produce(s) endospores?
Archy [21]

Answer:

E) Both Bacillus and Clostridium.

Explanation:

Bacterial endospores production is part of its survival mechanism. Bacteria produces these highly resistant spores that lies dormant in vegetative state, used during unfavourable and stressful environmental conditions. They are produced by gram positive bacteria such as Bacillus and Clostridium, and can lay dormant for years. Endospores are non-reproductive structures resistant to radiations, starvation and chemical disinfectants.

Licemer1 [7]

Microorganisms play key roles in the cycling of important nutrients in plant nutrition, particularly those of microorganisms play key roles in the cycling of important nutrients in plant nutrition, particularly those of carbon, nitrogen and sulfur.

<h3>What is Microorganisms?</h3>

Microorganisms, often known as microbes, are minute organisms that can be single cells or colonies of cells.

Ancient texts like the Jain scriptures from India's sixth century BC raised the specter of the potential existence of invisible microscopic life. In the 1670s, Anton van Leeuwenhoek used a microscope to observe microorganisms, which marked the beginning of the scientific study of microbes. Louis Pasteur disproved the hypothesis of spontaneous generation in the 1850s by discovering that bacteria were to blame for food degradation. Robert Koch determined in the 1880s that bacteria were to blame for tuberculosis, cholera, diphtheria, and anthrax.

Oxygen molecules are too small and glucose molecules are quite large than oxygen. So they can't passively disuse inside a cell.

Option C

<h3><u>Explanation:</u></h3>

Glucose molecules are large molecules with a molecular formula of C₆H₁₂O₆ These molecules need special protein channels or transporters called Glucose Transporters or GLUT to make them way through the cell membranes. While smaller molecules like oxygen, carbon dioxide, smaller polar molecules like <em>water</em> or even fat soluble molecules like chloroform and benzene do pass through the membranes easily by means of passive diffusion.

The oxygen molecules are needed inside a human cell for aerobic respiration and glucose molecules are needed because of a respiratory substrate. So Glucose needs receptors and transporters to pass through the membranes.
