ALGAE 


Algae are defined as an aquatic,photosynthetic and nucleus bearing Thallophytes . Their sex organs are wither Unicellular and Multicellular and not presented in sterile envelope. Algae - The term derived from the latin word alga: Washed away plants on seashore or seaweeds.It can able to produce many celled sex organs.But there is no sterile sex organ except Chara.
The study of algae is called  Algology or  Phycology. (Phycos-Seaweeds)
The term Algae was first introduced by Linnaeus in 1754.
HABITAT: Live in moist and aquatic habitats
PLANT BODY: Thalloid
RICH IN: Chlorophyll,cell wall rich in Cellulose, and presence of other photosynthetic pigments in chromatophores
NUTRITION: Autotrophic
MOTILITY: Cells motile due to presence of Flagella or cilia
REPRODUCTION:- 
  • Primitive algae:-Vegetative methods
  • Higher forms:-Sexual and asexual reproduction
Asexual Reproduction occurs due to Motile zoospores.
In unicellular,Entire organisms act as a gametes and in multicellular, Gametes produced from Unicellular and Multicellular Gametangium[No sterile Jacket]
Sexual Reproduction occurs due to Isogamous,Anisogamous and Oogamous.
Zygote develops a thick wall to form an oospore



Upcoming:- ALGAE BASIC INFORMATION SERIES PART 2 - LIFE CYCLE OF ALGAE

Hi Folks!! Follow our blog on Instagram  LAB IN THE BOX MELANOMA What is Melanoma? Melanoma is a form of skin cancer arising from melanocytes, the pigment-producing cells in the skin. While it is less common than other skin cancers, it is significantly more dangerous due to its ability to spread (metastasize) to other parts of the body if not caught early. Causes and Risk Factors The primary cause of melanoma is exposure to ultraviolet (UV) radiation from the sun or tanning beds. Factors that increase the risk of melanoma include: - Fair Skin : Less melanin provides less protection from UV radiation. - History of Sunburns : Severe, blistering sunburns, especially in early life, increase risk. - Excessive UV Exposure : Frequent use of tanning beds or extensive sun exposure. - Family History : A family history of melanoma increases risk. - Moles : Having many moles or unusual moles can be a risk factor. - Weakened Immune System : Immunocompromised individuals are at higher risk.

Warmer climate may Drive Fungi to be more dangerous to our Health!!

  Warmer climate may Drive Fungi to be more dangerous to our Health!! The world is filled with tiny creatures that sometimes found it delicious. Bacteria and viruses are so obvious that they are pathogenic . However recent news from Duke University School of medicine found that raised temperature  cause a pathogenic fungus known as Cryptococcus deneoformans to turn its adaptative responses into overdrive. This increases its number of genetic changes, some of which might presumably lead to higher heat resistance, and others perhaps toward greater disease-causing potential . " Fungal diseases are on the rise, largely because of an increase in the number of people who have weakened immune systems or underlying health conditions," Gusa said. But at the same time, pathogenic fungi may be adapting to warmer temperatures as well. Materials  provided by  Duke University .                             ...

History of Biotechnology

HISTORY OF BIOTECHNOLOGY: People have been harnessing biological processes to improve their quality of life for some 10,000 years, beginning with the first agricultural communities. Approximately 6,000 years ago, humans began to tap the biological processes of microorganisms in order to make bread, alcoholic beverages, and cheese and to preserve dairy products. But such processes are not what is meant today by biotechnology, a term first widely applied to the molecular and cellular technologies that began to emerge in the 1960s and ’70s. A fledgling “biotech” industry began to coalesce in the mid- to late 1970s, led by Genentech, a pharmaceutical company established in 1976 by Robert A. Swanson and Herbert W. Boyer to commercialize the recombinant DNA technology pioneered by Boyer, Paul Berg, and Stanley N. Cohen. Early companies such as Genentech, Amgen, Biogen, Cetus, and Genex began by manufacturing genetically engineered substances primarily for medical and environmental uses. For ...
