Pollen grains are in the Binucleate stage at the time of pollination.
Pollen of angiosperms may be either binucleate or trinucleate at maturity. The generative cell divides mitotically to give rise to the two male gametes before pollen grains are shed.
A two-celled pollen grain consisting of a tube cell and a generative cell. The generative cell ultimately divides to yield two sperm cells well after pollination takes place.

Passion fruit is a Day neutral plant. Day-neutral plants do not depend upon the amount of darkness or daylight hours. It flowers regardless of the length of the period of light it is exposed to.
The passion fruit is the fruit of several plants in the genus Passiflora. Passion fruits are round or oval, and range from a width of 1.5 to 3 inches. Several varieties of passionfruit are rich in polyphenols, and some contain prunasin and other cyanogenic glycosides in the peel and juice.

The richest source of iron is spinach.
A cup of cooked spinach contains about 6.5 mg of iron, which is a fair amount, considering that an average person needs about eight milligrams a day.
Spinach provides many health benefits but very few calories. About 3.5 ounces (100 grams) of raw spinach contain 2.7 mg of iron or 15% of the DV. Although this is non-heme iron, which isn't absorbed very well, spinach is also rich in vitamin C.

The mature embryo sac consists of four cell types; the egg cell, synergids, antipodal cells and polar nuclei. The correct statement about the cells present in the embryo sac is 3 antipodal cells, 2 synergids, an egg cell and a 2n secondary nucleus.
The egg cell and the two synergids at the micropolar end, the antipodals at the chalazal end and the central cell containing the two polar nuclei and a large central vacuole.

Hill soils are deficient in Nitrogen.
Soils of the hills and mountains are defined to be those found in areas with altitudes above 300 m above sea level and slopes of 18% and above. They were developed from various rocks mostly shale and sandstone, basalt and andesite, and limestone. Major land uses in these soils include forests, grasses and shrubs.
Hill soils are generally termed as acidic with high organic matter and are prone to erosion.

The optimum seed rate for marigolds is 1.5 (kg/ha).
Seed rate is the quantity of seed of a crop that is required to sow a unit area of land for optimum crop production.
Marigolds germinate quickly, sprouting within a few days and blooming in about 8 weeks, making them easy to grow from seed.

Wax coating treatments enhance the shelf life of fruits because it blocks Transpiration.
Transpiration is the loss of water from fruits and vegetables and includes the transport of moisture through the skin of the commodity, the evaporation of this moisture from the commodity surface and the convective mass transport of the moisture to the surroundings.
Fruit waxing is the process of covering fruits with artificial waxing material. The primary reasons for waxing are to prevent water loss and thus retard shrinkage and spoilage, and to improve appearance. Eg: apples.

Manganese deficiency causes marsh spots in pea. This disorder is prevalent in alkaline soils.
The soils with Marsh Spot contained less salt-soluble manganese than those on which peas were free from the disease, but this relation depended essentially on the contrast between acid and alkaline soils.
Mn serves as a cofactor and a catalyst in various metabolic processes in different cell compartments, such as the oxygen-evolving complex of photosystem II (PSII) or reactive oxygen species scavenging.

The Institute is located at Thanjavur, the ancient capital of Chola Kingdom and the granary of Tamil Nadu.
In its upgraded form, The National Institutes of Food Technology, Entrepreneurship and Management Act, 2021 was published in the Gazette of India on 30^th July 2021 and the name of IICPT has been changed to National Institute of Food Technology.
This institute aims to focus on providing solutions to all food processing areas including fish, meat and dairy products processing through intensive research and development activities.

Pruning in ber is done during Spring.
Pruning is done during the hot and dry season when the tree sheds leaves and enters into dormancy. In Tamil Nadu, the trees are pruned from January - April, in Maharashtra and Gujarat pruning must be completed by the April end and in Haryana by the May end.
Annual pruning in ber is essential to induce the maximum number of new healthy shoots which would bear good quality fruits. It is also essential to remove the undesirable, weak, intercrossing, diseased and broken branches to avoid crowding and to encourage healthy growth for maximum fruit bearing.
