This page features Drosophila life cycle game Quiz Online Free. It is an interactive activity in which students will answer questions related to the fruit fly. After playing this game, students will learn a lot to tackle more complex problems.
The life cycle of Drosophila consists of four distinct stages: the egg, larva, pupa, and adult. The Drosophila life cycle is fascinating, and you'll probably want to know all about it! Here, we'll describe the stages of Drosophila development, from the egg to the adult. You may also be interested in learning about their life history, including their larvae, pupae, and adults. But if you're not sure how they develop, let's first cover the Embryo.
The Drosophila life cycle can be viewed in a variety of ways. Drosophila is very fertile, laying hundreds of eggs daily. Once they have mated, they continue to fertilize eggs. Both the male and the female are similar in size, but the male has darker external genitalia and is more pigmented on its lower abdomen. Males have sex combs and bristles on their forelegs. They are useful for genetic crosses, but they are much smaller.
The larval stage in the drosophila life cycle consists of alternating phases of activity and rest. In the larval stage, the insect eats mainly by digging with its mouth hooks downward and its butt upward, exposing holes in its body for breathing. The larval stage of the insect lasts approximately five days and increases in size by approximately 200 times. It begins as a tiny worm with an average length of about 3 mm, but grows up to 200 times its original size.
Drosophila larvae exhibit a unique metabolic program that efficiently converts nutrients into biomass. This metabolic program is regulated by a nuclear receptor, the equivalent of estrogen-related receptors in mammals. It coordinates the transcription of genes involved in glycolysis, the pentose phosphate pathway, and lactate production. This metabolic program is found to last throughout the larval stage. In addition, the larval metabolic program has been shown to be an adaptation to life in crowded conditions.
The egg stage lasts for only a few hours, while the larvae develop over several days and go through three molts. At the end of the larval stage, the fly develops into an adult. Pupae can now float in water, thanks to a gas bubble formed in the abdomen.
The adult Drosophila has 10 pairs of imaginary discs. The genital discs form the reproductive organs, while the abdominal epidermis is made from histoblasts, a group of specialized imaginal cells. The imaginal discs have been used extensively to unravel the role of genes in adult structures. The pupa is the first generation of the drosophila life cycle.
The development time of Drosophila melanogaster is dependent on temperature and is usually completed within one to two weeks. At 68 degrees F, the spotted wing drosophila reaches its highest reproductive stage. During higher temperatures, egg laying decreases. Females can lay as many as 300 eggs during their lifetime. This is an indication of their high reproductive efficiency. In addition, this species has multiple generations per year, with each generation containing tens of thousands of individuals.
