Air plays an important role in the life of mosquito larvae because they need oxygen to breathe. Mosquito larvae have a special structure called a siphon, which allows them to reach the surface of the water and take in air. ...

Stagnant water is associated with mosquito breeding because mosquitoes lay their eggs on the surface of still or stagnant water. The eggs hatch into larvae, which need water to grow and develop. Since stagnant water doesn’t move or get disturbed, ...
A mosquito’s life cycle has four stages: egg, larva, pupa, and adult. First, the female mosquito lays eggs on the surface of water. The eggs hatch into larvae, which swim in the water and feed on tiny organisms. Next, the ...
The life cycle of animals differs from plants in that animals usually start from an egg or a baby, depending on the species. They grow, develop, and reproduce, giving birth to new offspring. Unlike plants, animals do not produce seeds. ...
The life cycle of a plant starts with a seed. When the seed gets the right conditions (water, warmth, and air), it germinates and a small root and stem begin to grow. The plant then grows into an adult, producing ...
Plant roots typically grow downwards, towards the center of the Earth, in response to gravity. This is known as gravitropism. Roots grow downward to anchor the plant in the soil and to search for water and nutrients. The growth direction ...

Sunlight plays an important role in seed germination by providing the energy needed for the seedling to grow. While seeds don’t always need direct sunlight to start germinating, once the seedling begins to sprout, sunlight helps it produce food through ...
Seeds need water to germinate because water activates the enzymes inside the seed that help start the growth process. It softens the seed coat, allowing the seed to swell and crack open. Water also helps transport nutrients inside the seed, ...
For seed germination, three main conditions are necessary: water, warmth, and air (oxygen). Water is absorbed by the seed, activating the enzymes that start the growth process. Warmth helps the seed to metabolize and grow, while oxygen is needed for ...
