Structure of Cell Organelles Cell membrane Temporal cell organelles: Chromosome, centrosome, endosome and autophagosome are only found at specific stages of the cell’s life cycle.Ĭell organelles specific to cell type: Chloroplast, central vacuole and cell wall are present in plant cells but not in animal cells. General cell organelles: Cell membrane, mitochondrion, rough endoplasmic reticulum, smooth endoplasmic reticulum, lysosome, plastid, ribosomes, Golgi bodies, nucleus and cytoskeleton are a few examples present in both animal and plant cells at all times. They are involved in various functions, including energy synthesis, protein and secretion formation, toxin destruction and reacting to external signals.Ĭell organelles can be divided into three categories: Organelles are tiny structures in the cytoplasm that perform functions that keep the cell in a state of homeostasis.
The cytoplasm is a liquid network surrounding the nucleus, separated by the cell’s outer membrane.
A nuclear envelope surrounds the nucleus, which contains the genetic code in the format of a chromosome. The cytoplasm and the nucleus are the two major sections of a cell. We will look in detail at the cell organelles and their functions. They also distinguish one function from another. A membrane must surround the systems within a cell that performs different functions hence, organelles are entirely membrane-bound. They serve a crucial purpose because we must compartmentalise all the operations within the cell.
Cell organelles are specialised structures within cells that come in various shapes and sizes.
