Definition: The nucleus is a membrane bound structure that contains the cell's hereditary information and controls the cell's growth and reproduction. It is commonly the most prominent organelle in the cell.The nucleus is surrounded by a structure called the nuclear envelope.This membrane separates the contents of the nucleus from the cytoplasm. The cell's chromosomes are also housed within the nucleus.t is commonly the most prominent organelle in the cell. The nucleus is surrounded by a structure called the nuclear envelope. This membrane separates the contents of the nucleus from the cytoplasm. Math/Science Nucleus ©1990,2000 6 Students use a microscope toobserve plant and animal cells.

There are some reproductive strategies that are difficult to classify for students.Ferns, fungi, and some protozoa reproduce by spore production. Spores are formed bydivisions of special mother cells and are rel eased from the parent or ganism. 5 living substances. Therefore, these cells with anucleus contain three basic parts: (1) an outermembrane, (2) the cytoplasm, and (3) the nucleus.Cells with three basic parts are called eukaryote cells. There are many unicellular living thingsthat consist of a single eukaryote cell; that is, theyare a 3-part cell.hloroplast (klor’\klôr).
