Parthenocarpy is the development of fruits without fertilization, resulting in seedless fruits. Common examples include bananas and some varieties of grapes and oranges widely preferred in commercial agriculture.

After fertilization, the ovary of a flower develops into a fruit while the ovules become seeds. The fruit protects the seeds and often helps in their dispersal through animals, wind, or water.

A camera lens forms a real, inverted, and usually diminished image on the film or image sensor. The lens focuses incoming light rays onto a surface, allowing the captured image to be recorded accurately for photography or digital imaging.

In petroleum refineries, crude oil is typically heated to around 400°C before entering the fractional distillation column. Heating separates hydrocarbons into products such as petrol, diesel, kerosene, and lubricating oils based on boiling points.

The smooth endoplasmic reticulum (SER) is responsible for the synthesis of lipids, including fats and steroids. It also helps in detoxification processes and calcium storage, especially in liver and muscle cells.
