Plasmids – Structural Details, Functional Roles, and Applications in Genetic Engineering

- by Jaishree Gorane - Leave a Comment

Plasmids are small, circular DNA molecules found in bacteria, separate from chromosomal DNA. They have unique features such as antibiotic resistance and toxin production. Plasmids come in various types like F-plasmids, R-plasmids, and Col plasmids. They replicate independently and facilitate gene transfer through conjugation. Plasmids are also key in genetic engineering and biotechnology.

Gymnosperm Overview- Characteristics, Classification, Life Cycle, Examples, and Economic Impact

- by Jaishree Gorane - Leave a Comment

Gymnosperms, seed-producing vascular plants, lack flowers and fruits, exposing their seeds on cone scales. Originating in the Paleozoic era, their characteristics include naked seeds, needle-like leaves, and wind pollination. Divided into four groups—Cycadophyta, Coniferophyta, Ginkgophyta, Gnetophyta—they play crucial ecological roles and have significant economic value in food, medicine, and industry.

Chemosynthesis is a process where chemosynthetic bacteria convert inorganic compounds into energy-rich organic compounds. It occurs in environments lacking sunlight. The equation for chemosynthesis is carbon dioxide + water + inorganic compounds → organic compounds + sulphur compounds. Chemosynthetic bacteria, like sulphur bacteria, iron bacteria, and nitrifying bacteria, are examples of organisms that carry out chemosynthesis. Chemosynthesis differs from photosynthesis in energy sources and reactions.

Chloroplast – Definition, Structure, Distribution, function and Diagram

- by Jaishree Gorane - 1 Comment

Chloroplasts, found in plant cells, are defined as organelles that contain chlorophyll. They have a complex structure with outer and inner membranes, stroma, thylakoid membranes and grana. Functionally, chloroplasts play a key role in photosynthesis. They convert light energy into chemical energy, produce ATP and oxygen and fixing carbon dioxide. The diagrams illustrate the structure and functions of chloroplasts in plant metabolism.

Salivary glands are exocrine glands responsible for saliva secretion. They have acinar cells for saliva synthesis and ductal cells for transport. Myoepithelial cells aid saliva movement. Major glands include parotid (largest), submandibular, and sublingual (smallest). Ducts are Stensen’s (parotid), Wharton’s (submandibular), and multiple (sublingual). Saliva lubricates, digests, and protects. Understanding their structure and function is vital.
