Which non-toxic, fast growing cyanobacterium is cultivated in tanks as a protein-rich animal feed?

botany strategies for enhancement in food production balanced diet food production and microbes plant breeding for food production

  1. Stigonema

  2. Spirulina

  3. Nostoc

  4. Oscillatoria

Show answer
Correct Option: B
Explanation:
Spirulina represents a biomass of cyanobacteria (blue-green algae) that can be consumed by humans and other animals. The two species are Arthrospira platensis and A. maxima. Cultivated worldwide, Arthrospira is used as a dietary supplement or whole food. It is also used as a feed supplement in the aquaculture, aquarium, and poultry industries. Spirulina was found in abundance at Lake Texcoco by French researchers in the 1960s, but no reference to its use was made by the Aztecs as a daily food source after the 16th century, probably due to the draining of the surrounding lakes for agriculture and urban development. As an ecologically sound, nutrient-rich, dietary supplement, spirulina is being investigated to address food security and malnutrition, and as dietary support in long-term space flight or Mars missions. Its interest for food security is for lower land and water needs to produce protein and energy than required for livestock as meat sources.
So the correct option is 'spirulina'.

Which is taken as protein supplement in diet?

  1. Chlorella

  2. Spirulina

  3. Both A and B

  4. None of the above

Show answer
Correct Option: C
Explanation:

Chlorella is a type of algae that grows in fresh water. The whole plant is used to make nutritional supplements and medicine. It is processed and made into tablets and liquid extracts. These extracts contain "chlorella growth factor," which is described as a water-soluble extract of chlorella containing chemicals including amino acids, peptides, proteins, vitamins, sugars, and nucleic acids. As a medicine, chlorella is used for preventing cancer, reducing radiation treatment side effects, stimulating the immune system, improving response to flu vaccine, increasing white blood cell counts (especially in people with HIV infection or cancer), preventing colds, protecting the body against toxic metals such as lead and mercury, and slowing the aging process.
Chlorella is also used to increase good bacteria in the intestine in order to improve digestion; and to help treat ulcers, colitis, Crohn's disease, and diverticulosis.
Some people also use chlorella for the prevention of stress-related ulcers; treatment of constipation, bad breath, and hypertension; as an antioxidant; to reduce cholesterol; to increase energy; to detoxify the body; and as a source of magnesium to promote mental health, relieve premenstrual syndrome (PMS), and reduce asthma attacks. It is also used for fibromyalgia.
Chlorella is applied to the skin for treating skin ulcers, rashes caused by radiation treatment, and a sexually transmitted disease called trichomoniasis. Chlorella is a good source of protein, fats, carbohydrates, fiber, chlorophyll, vitamins, and minerals. The cell wall of chlorella must be broken down before people can digest it.

Spirulina is a cyanobacterium that can be consumed by humans and other animals as a protein supplement.

The importance of fungi in food web lies in the fact that

botany micro - organism fungi: benefits and harmful effects useful and harmful fungi uses of fungi

  1. They are photoautotrophs.

  2. They have prokaryotic cell structure.

  3. They serve as key decomposers of dead organic matter.

  4. They generate antibiotics that kill competing plants and animals.

Show answer
Correct Option: C
Explanation:
  • Fungus are an important part of the saprophytic food chain.
  • They decompose the organic waste left by other animals and convert it into inorganic components that can be again absorbed by the plants ie the organisms of the first trophic level of the food chain and enter the food chain again.
  • So, the correct answer is 'They serve as key decomposers of dead organic matter'.

Calcium gluconate is widely used as a source of calcium for infants. It is prepared from

  1. Rhizopus

  2. Aspergillus

  3. Mucor

  4. None of the above

Show answer
Correct Option: B
Explanation:

Aspergillus niger is filamentous fungi that cause disease on vegetables and fruits called black mould. These organisms are used in fermentation processes to obtain citric acid and gluconic acid that are of commercial importance. It is also used in the manufacture of calcium gluconate. This compound is given to infants from hypocalcemia. Thus, the correct answer is option B.

Which of the tissue is more important for translocation of sucrose?

botany plant physiology mineral absorption transport of food, water and minerals mineral transport theories of translocation transport in the phloem of plants

  1. Xylem

  2. Phloem

  3. Both of the above

  4. None of the above

Show answer
Correct Option: B
Explanation:

Translocation of organic nutrients from the region of source or supply to the region of sink or utilisation is mostly in the form of sucrose. Phloem (sieve tubes or sieve cells) is the pathway for this translocation, as found put by stem girdling, sieve tube puncturing, radioautography and chemical analysis of sieve tube sap.
