Shreya Desai answered |
The lenticels functions as a pore, providing a pathway for the direct exchange of gasesbetween the internal tissues and atmosphere through the bark, which is otherwise impermeable to gases.The lenticels help in the gaseous exchange between the atmosphere and the internal tissue of the stem. The lenticels also helps in transpiration called as the lenticular transpiration.Lenticels are a portions of periderm with numerous intercellular spaces and loosely organized cells

Gymnosperms evolved to have seeds but do not have flowers. Examples of gymnosperms include the Redwood, Fir, and Cypress trees. Gymnos means "naked" in Greek; the seeds of gymnosperms are naked, not protected by flowers. Flowering plants, or angiosperms, evolved to have vascular tissue, seeds, and flowers.

We know plants prepare their own food and so are known as autotrophs. With the help of photosynthesis they make food in which they produce glucose from carbon dioxide and sunlight. Also, oxygen is released by plants which is further used by humans and other animals. But Fungi lack chlorophyll and do not engage in photosynthesis.

Ashutosh Chavan answered |
Short day plants are those plants that begin flowering when the days are shorter than their critical day length. They require the long period of darkness and the short period of light to flower. Long day plants are those plants that begin flowering when the days are longer than their critical day length. They will flower when they are exposed to the short period of darkness and the long period of light. Day neutral plants do not depend upon the amount of darkness or daylight hours for flowering. They flower independent of day length. Examples of day neutral plants are sunflower and tomato.

Essential Service Maintenance Act
The correct answer is option 'B', Essential Service Maintenance Act. This act is designed to ensure the maintenance of essential services during times of crisis or emergencies. Here is a detailed explanation of this answer:
Definition:
The Essential Service Maintenance Act (ESMA) is a legislation that empowers the government to declare any service as "essential" for the maintenance of public order. This act allows the government to prohibit strikes and lockouts in essential services to ensure their uninterrupted operation.
Objective:
The main objective of ESMA is to prevent disruptions in essential services such as healthcare, transportation, communication, and public utilities during times of crisis. By prohibiting strikes and lockouts in these sectors, the act aims to safeguard the interests of the public and ensure the smooth functioning of vital services.
Implementation:
ESMA is typically invoked by the government when there is a threat of disruption in essential services due to strikes or other forms of industrial action. Once declared, the act empowers the authorities to take necessary measures to maintain the continuity of essential services and prevent any disruptions that may affect public order.
Controversies:
While ESMA serves an important purpose in safeguarding essential services, it has also faced criticism for restricting the rights of workers to strike and bargain collectively. Some argue that the act infringes on the fundamental rights of workers and limits their ability to negotiate for better working conditions.
In conclusion, the Essential Service Maintenance Act plays a crucial role in ensuring the uninterrupted operation of essential services during emergencies. While it is a powerful tool for maintaining public order, it is important to strike a balance between the interests of the public and the rights of workers.

Abiotic pollination refers to situations where pollination is mediated without the involvement of other organisms. The most common form of abiotic pollination, anemophily, is pollination by wind. This form of pollination is predominant in grasses, most conifers, and many deciduous trees.Of the 20% of abiotically pollinated species, 98% are anemophilous and 2% hydrophilous, being pollinated by water.

The most important are: Carbon, hydrogen and oxygen – Available from air and water and therefore in plentiful supply Nitrogen, phosphorus, potassium (a.k.a. potash) – The three macronutrients and the three elements you find in most packaged fertilizers.
Sulfur, calcium, and magnesium – Secondary nutrients
Boron, cobalt, copper, iron, manganese, molybdenum and zinc – Micronutrients
