Question 1

Question 3

Most of the summer vegetables are:&#10;A)Annual&#10;B)Biennial&#10;C)Perennial&#10;D)None

Accepted Answer

Most summer vegetables are annuals, meaning they complete their life cycle—from germination to the production of seeds—within one year, and then die. This includes common summer vegetables like tomatoes, peppers, and cucumbers.

Question 4

In seed formation the inner integument remains thin and develops into:&#10;A)Testa&#10;B)Tegmen&#10;C)Aril&#10;D)Hilum

Accepted Answer

The inner integument of a seed develops into the tegmen, which is the inner layer of the seed coat, providing additional protection to the developing embryo.

Question 5

During seed formation, a sear left by the funiculus is termed as&#10;A)Hilum&#10;B)Funiculus&#10;C)Operculum&#10;D)Raphe

Accepted Answer

The hilum is the scar left on the seed surface where the funiculus (the stalk attaching the ovule to the ovary wall) was attached, marking the seed's point of attachment to the fruit.

Question 6

Cracking in tomato fruit is due to:&#10;A)High nitrogen level&#10;B)Temperature fluctuations&#10;C)Soil moisture fluctuations&#10;D)All of these

Accepted Answer

Cracking in tomato fruit can be caused by a combination of factors including high nitrogen levels, temperature fluctuations, and soil moisture fluctuations. These conditions can lead to uneven growth rates in the fruit, causing the skin to crack.

Question 7

Endosperm like tissue (2n) in seed developing from nucellus is :&#10;A)Endospem&#10;B)Cotyledom&#10;C)Perisperm&#10;D)Mericarp

Accepted Answer

Perisperm is the correct answer because it is a nutritive tissue found in some seeds that develops from the nucellus, a part of the ovule. Unlike the endosperm, which is typically triploid (3n) and forms as a result of double fertilization, perisperm is diploid (2n) and originates directly from the maternal tissue.

Question 8

Orthodox seeds after dissemination may be&#10;A)None dormant&#10;B)Dormant&#10;C)Quiescent&#10;D)All of above

Accepted Answer

Orthodox seeds can exhibit a range of conditions after dissemination, including being non-dormant (ready to germinate under suitable conditions), dormant (requiring specific conditions or treatments to break dormancy), or quiescent (metabolically inactive but will germinate when conditions are favorable), hence all of the options are correct.

Question 9

Secondary dormancy in non dormant seeds is due to:&#10;A)Temperature&#10;B)Moisture&#10;C)Aeration&#10;D)Light

Accepted Answer

Secondary dormancy in non dormant seeds is due to temperature.

Question 10

Germination of undeveloped seeds is favored by:&#10;A)Warm temperature (>20&#176;C)&#10;B)Gibberallic acid&#10;C)Low temperature (<20&#176;C)&#10;D)a & b

Accepted Answer

Warm temperatures (generally above 20°C) and gibberellic acid are both known to promote the germination of seeds. Warm temperatures help by providing the energy necessary for metabolic processes, while gibberellic acid is a plant hormone that stimulates seed germination and growth.
