Dec 5, 2023 · The nucleus of a cell contains chromatin (a complex of DNA and histone proteins) which is the genetic material of the cell. Present in all eukaryotic cells, the nucleus is relatively large and separated from the cytoplasm by a double membrane (the nuclear envelope) which has many pores.
Dec 26, 2023 · An organelle is a compartment within a eukaryotic cell that has a specific function. The name “organelle” comes from the idea that these structures are to cells what an organ is to the body. Typically, organelles are enclosed within their own lipid bilayers.
Oct 12, 2023 · Cell Organelles. An organelle is a membrane-bound structure found within a eukaryotic cell. It is similar to an organ in an animal body. There are many cell organelles in a cell, each having a distinct structure and specific functions. Some are without membrane, while others are either single or double-membrane-bound.
Oct 21, 2021 · Structure and Characteristics of a Plant Cell. A model of a typical plant cell is found to be rectangular in shape, ranging in size from 10 to 100 µm. Under the microscope, it shows many different parts. Each part, known as an organelle, works together to keep the cell functional.
Nucleus – this controls what happens in the cell. It contains DNA, the genetic information that cells need to grow and reproduce. Cytoplasm – this is a jelly-like substance in which chemical ...
