    Which chemical is used for de-greening of fruit?

    • A.

      IBA

    • B.

      Cytokinin

    • C.

      Auxin

    • D.

      Gibberalic acid

    • E.

      Ethylene

    Correct Answer
    E. Ethylene
    Explanation
    Ethylene is used for de-greening of fruit. Ethylene is a plant hormone that regulates various physiological processes, including fruit ripening. When applied to unripe fruit, ethylene promotes the breakdown of chlorophyll, which is responsible for the green color, resulting in the de-greening of the fruit. This process is commonly used in the fruit industry to accelerate the ripening of fruits such as bananas, tomatoes, and avocados.

    Development of embryo without fertilization is known as _________

    • A.

      Parthenocarpy

    • B.

    • C.

      Apomixsis

    • D.

      Unfertility

    • E.

      None of these

    Correct Answer
    A. Parthenocarpy
    Explanation
    Parthenocarpy refers to the development of an embryo without fertilization. This process occurs in certain plants where the ovary develops into a fruit without the need for pollination or fertilization. Parthenocarpy can be induced artificially in some plants to produce seedless fruits, such as seedless grapes or bananas. Parthenogenesis, on the other hand, refers to the development of an embryo from an unfertilized egg, typically seen in some invertebrates and reptiles. Apomixis is a type of reproduction in plants where seeds are produced without fertilization, but it does not involve the development of an embryo. Therefore, the correct answer is Parthenocarpy.

    • C.

      Apomixsis

    • D.

      Unfertility

    • E.

      None of the above

    Correct Answer
    A. Parthenogenesis
    Explanation
    Parthenogenesis refers to the development of an embryo from an unfertilized egg. In this process, the egg undergoes cell division and develops into an embryo without the need for fertilization by sperm. Parthenogenesis is a form of asexual reproduction that occurs naturally in some species, such as certain insects, reptiles, and plants. It allows for the production of offspring without the involvement of a male individual.

    Explanation
    Auxin is a plant hormone that plays a crucial role in regulating the growth and development of plants. One of its main functions is to promote cell elongation, which is the process by which cells increase in length. This allows plants to grow taller and develop longer stems and roots. Auxin also influences other processes such as cell division, cell differentiation, and cell production, but its primary role is in cell elongation.

    • D.

      Fungus

    • E.

      Type B insect

    Correct Answer
    A. Virus
    Explanation
    Dwarfness in sugarcane is caused by a virus. Viral infections can result in stunted growth and reduced size in plants, including sugarcane. These viruses can be transmitted through infected plant material or by insect vectors. Once infected, the virus disrupts the normal growth and development of the sugarcane plant, leading to dwarfness. Bacteria, insects, and fungi can also cause diseases in sugarcane, but in this case, the correct answer is virus.

    The correct answer is potassium, phosphorus, and nitrogen. These three elements are considered macronutrients because they are required by plants in large quantities for their growth and development. Potassium is essential for enzyme activation, water regulation, and nutrient transport in plants. Phosphorus is involved in energy transfer and storage, cell division, and root development. Nitrogen is a crucial component of amino acids, proteins, and chlorophyll, playing a vital role in plant growth and photosynthesis.

      Only male plants

    • B.

      Female and hermaphrodite

    • C.

      Male and hermaphrodite plants

    • D.

    • E.

      Only seedless Papaya

    Correct Answer
    D. Only female plants
    Explanation
    Gynodioecious varieties of papaya produce only female plants. This means that these varieties do not produce male or hermaphrodite plants. Gynodioecy is a type of sexual system in plants where some individuals are female and others are hermaphrodite. In the case of papaya, gynodioecious varieties have been selectively bred to produce only female plants, as these are the ones that bear fruit. This ensures a higher yield of papaya fruits for commercial purposes.

    • B.

      Moderately tolerant

    • C.

      Sensitive

    • D.

      Low tolerant

    • E.

      Proficly tolerant

    Correct Answer
    B. Moderately tolerant
    Explanation
    Grapes are considered to be moderately tolerant to salinity. This means that they can withstand moderate levels of salt in the soil or water. While they may not thrive in highly saline conditions, they are able to tolerate a certain amount of salt without significant negative effects on their growth and productivity. Grapes have developed mechanisms to regulate water and ion uptake, which helps them cope with moderate salinity levels. However, excessive salinity can still have detrimental effects on grapevines, so it is important to manage irrigation and soil conditions carefully to ensure optimal growth and yield.
