Gaaffii 1

What is totipotency in plant cell and tissue culture?

  1. A.The capacity of a cell to develop into an organism by regeneration
  2. B.The ability of a plant to grow without water or light
  3. C.The method of removing the cell wall from a plant cell
  4. D.The transfer of genes between unrelated organisms
Deebii fi sababa agarsiisi

Deebii: A The capacity of a cell to develop into an organism by regeneration

Sababa

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.

Gaaffii 2

In plant tissue culture, which plant hormone is added to the medium to stimulate shoot development?

  1. A.Cytokinins
  2. B.Auxins
  3. C.Ethylene
  4. D.Beta-carotene
Deebii fi sababa agarsiisi

Deebii: A Cytokinins

Sababa

In tissue culture, cytokinins are used to stimulate shoot development, whereas auxins are used to stimulate root development.

Gaaffii 3

What term is used for plant cells that have had their cell walls removed?

  1. A.Protoplasts
  2. B.Explants
  3. C.Clones
  4. D.Tubers
Deebii fi sababa agarsiisi

Deebii: A Protoplasts

Sababa

Protoplasts are single plant cells without cell walls that can be cultured to generate new plants.

Gaaffii 4

According to the textbook, which two plants have seeds with very low chances of germinating naturally and benefit from tissue culture?

  1. A.Orchids and nepenthes
  2. B.Teff and wheat
  3. C.Coffee and tea
  4. D.Cucumber and banana
Deebii fi sababa agarsiisi

Deebii: A Orchids and nepenthes

Sababa

The textbook specifically identifies orchids and nepenthes as examples of plants whose seeds have very low chances of germinating and growing under natural conditions.

Gaaffii 5

Why are male asparagus plants preferred commercially over female plants?

  1. A.Male plants give higher yields
  2. B.Male plants produce larger seeds
  3. C.Male plants resist all insect pests
  4. D.Male plants do not need soil nutrients
Deebii fi sababa agarsiisi

Deebii: A Male plants give higher yields

Sababa

Asparagus is dioecious with unisexual flowers. Male plants are high yielders and are commercially preferred over female plants.

Gaaffii 6

What are disease-free potato tubers washed with to remove impurities before sprouting in tissue culture?

  1. A.Detergent and distilled water
  2. B.Alcohol and auxin solution
  3. C.Pesticide and cytokinin liquid
  4. D.Warm milk and tap water
Deebii fi sababa agarsiisi

Deebii: A Detergent and distilled water

Sababa

In potato multiplication, the disease-free tubers are washed with both detergent and distilled water to remove impurities and allow clean sprouting.

Gaaffii 7

Which of the following is a major limitation of conventional plant breeding?

  1. A.It can only exchange genetic material between the same or closely related species
  2. B.It cannot produce any seeds or fruits
  3. C.It requires expensive laboratory glassware like autoclaves
  4. D.It allows direct transfer of single genes from any organism
Deebii fi sababa agarsiisi

Deebii: A It can only exchange genetic material between the same or closely related species

Sababa

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.

Gaaffii 8

Scientists created Golden Rice by inserting genes from which combination of sources?

  1. A.Daffodils, pea, a bacterium, and a virus
  2. B.Maize, wheat, an alga, and a fungus
  3. C.Potato, carrot, a yeast, and a virus
  4. D.Citrus, eucalyptus, aloe, and a bacterium
Deebii fi sababa agarsiisi

Deebii: A Daffodils, pea, a bacterium, and a virus

Sababa

Scientists inserted four genes from daffodils, pea, a bacterium, and a virus into rice to produce Golden Rice.

Gaaffii 9

A laboratory in Hawassa conducts plant tissue culture under aseptic conditions. What does this mean?

  1. A.The environment is free from disease-causing germs such as bacteria and viruses
  2. B.The room is completely vacuumed of all air and gases
  3. C.The plants are grown in natural field soil without containers
  4. D.The medium contains only solid rock and water
Deebii fi sababa agarsiisi

Deebii: A The environment is free from disease-causing germs such as bacteria and viruses

Sababa

An aseptic condition means the complete absence of germs, such as bacteria, viruses, and other microorganisms that can cause disease.

Gaaffii 10

Golden Rice is engineered to accumulate beta-carotene. What does the animal body convert beta-carotene into when consumed?

  1. A.Vitamin A
  2. B.Vitamin C
  3. C.Auxin
  4. D.Protein
Deebii fi sababa agarsiisi

Deebii: A Vitamin A

Sababa

Beta-carotene is converted into vitamin A when consumed by animals and humans, helping fight vitamin A deficiency.
