Learn about the three basic parts of all eukaryotic cells: the cell membrane, the nucleus, and the cytoplasm. Explore the different organelles found in animal and plant cells and their functions.

Plant, animal and fungal cells are eukaryotic cells. The nucleus in a eukaryotic cell is bound by a nuclear envelope and contains nucleoplasm. The cytoplasm, found between the plasma membrane and the nucleus, consists of fluid and the organelles.

The cell structure comprises individual components with specific functions essential to carry out life’s processes. These components include- cell wall, cell membrane, cytoplasm, nucleus, and cell organelles. Read on to explore more insights on cell structure and function. Cell Membrane. The cell membrane supports and protects the cell.

Cell Structure. The human cell – a eukaryotic cell with many cytoplasmic structures bounded by biological membranes. Table of Contents. The interior of human cells is divided into the nucleus and the cytoplasm. The nucleus is a spherical or oval-shaped structure at the center of the cell.

Learn about the basic unit of life, the cell, and its two main types: prokaryotic and eukaryotic. Compare their features, such as size, nucleus, organelles, DNA, and more.

The plasma membrane (often called the cell membrane) is a thin flexible barrier that separates the inside of the cell from the environment outside the cell and regulates what can pass in and out of the cell. Internally, the cell is divided into the cytoplasm and the nucleus.

Cells are microscopic building blocks of unicellular and multicellular living organisms. Animal, plant, fungal and bacterial cells are different in terms of structure but also have many...

Learn about the different types and functions of cell organelles, the functional units of a cell. Find out the structure and role of plasma membrane, nucleus, mitochondria, plastids, endoplasmic reticulum and more.

4.3: Studying Cells - Cell Theory. Cell theory states that living things are composed of one or more cells, that the cell is the basic unit of life, and that cells arise from existing cells. 4.4: Studying Cells - Cell Size. Cell size is limited in accordance with the ratio of cell surface area to volume.
