The amount of magnetic flux that rises up to the Sun's surface varies with time in a cycle called the solar cycle. This cycle lasts 11 years on average.

exists and is an alternate of . Making the world better, one answer at a time. The three main parts of the cell are the cell membrane (surrounds and protects the cell), the cytoplasm (the liquid inside the cell), and the nucleus (control center of the cell). Minor edit?
Based on their function, cells are categorized into different types of cells, the somatic cells and the reproductive cells. Each cell has a nucleus and a jellylike watery substance that is 80% water that occupies the remaining part of the cell. This is called Cytoplasm.he cytoplasm has cell components like endoplasmic reticulum, lysomes, mitochondria and Golgi apparatus. In the plant cells chloroplasts too are found in the organelles of cytoplasm which has a periphery surrounded by fatty membrane.
