በዚህ ምዕራፍ ላይ የተጻፉ 10 የምርጫ ጥያቄዎች፣ እያንዳንዳቸው መልሱና ምክንያቱ አላቸው። መልሱን ከመክፈትዎ በፊት ይሞክሩ። ጥያቄዎቹ በእንግሊዝኛ ናቸው።
ጥያቄ 1
What is totipotency in plant cell and tissue culture?
መልስ፦ A The capacity of a cell to develop into an organism by regeneration
ምክንያቱ
Totipotency is the basis of plant tissue culture and is defined as the capacity of a cell to regenerate and develop into a complete organism.
ጥያቄ 2
In plant tissue culture, which plant hormone is added to the medium to stimulate shoot development?
መልስ፦ A Cytokinins
ምክንያቱ
In tissue culture, cytokinins are used to stimulate shoot development, whereas auxins are used to stimulate root development.
ጥያቄ 3
What term is used for plant cells that have had their cell walls removed?
መልስ፦ A Protoplasts
ምክንያቱ
Protoplasts are single plant cells without cell walls that can be cultured to generate new plants.
ጥያቄ 4
According to the textbook, which two plants have seeds with very low chances of germinating naturally and benefit from tissue culture?
መልስ፦ A Orchids and nepenthes
ምክንያቱ
The textbook specifically identifies orchids and nepenthes as examples of plants whose seeds have very low chances of germinating and growing under natural conditions.
ጥያቄ 5
Why are male asparagus plants preferred commercially over female plants?
መልስ፦ A Male plants give higher yields
ምክንያቱ
Asparagus is dioecious with unisexual flowers. Male plants are high yielders and are commercially preferred over female plants.
ጥያቄ 6
What are disease-free potato tubers washed with to remove impurities before sprouting in tissue culture?
መልስ፦ A Detergent and distilled water
ምክንያቱ
In potato multiplication, the disease-free tubers are washed with both detergent and distilled water to remove impurities and allow clean sprouting.
ጥያቄ 7
Which of the following is a major limitation of conventional plant breeding?
መልስ፦ A It can only exchange genetic material between the same or closely related species
ምክንያቱ
Conventional breeding is limited to exchanging genetic material between the same or very closely related species, unlike genetic engineering which transfers genes across species barriers.
ጥያቄ 8
Scientists created Golden Rice by inserting genes from which combination of sources?
መልስ፦ A Daffodils, pea, a bacterium, and a virus
ምክንያቱ
Scientists inserted four genes from daffodils, pea, a bacterium, and a virus into rice to produce Golden Rice.
ጥያቄ 9
A laboratory in Hawassa conducts plant tissue culture under aseptic conditions. What does this mean?
መልስ፦ A The environment is free from disease-causing germs such as bacteria and viruses
ምክንያቱ
An aseptic condition means the complete absence of germs, such as bacteria, viruses, and other microorganisms that can cause disease.
ጥያቄ 10
Golden Rice is engineered to accumulate beta-carotene. What does the animal body convert beta-carotene into when consumed?
መልስ፦ A Vitamin A
ምክንያቱ
Beta-carotene is converted into vitamin A when consumed by animals and humans, helping fight vitamin A deficiency.
