lAnimal Cells: Structures and Organelles
The following are examples of structures and organelles that can be found in typical animal cells:
* Centrioles - organize the assembly of microtubules during cell division.
* Cytoplasm - gel-like substance within the cell.
* Endoplasmic Reticulum - extensive network of membranes composed of both regions with ribosomes (rough ER) and regions without ribosomes (smooth ER).
* Golgi Complex - responsible for manufacturing, storing and shipping certain cellular products.
* Lysosomes - sacs of enzymes that digest cellular macromolecules such as nucleic acids.
* Microtubules - hollow rods that function primarily to help support and shape the cell.
* Mitochondria - power producers and the sites of cellular respiration.
* Nucleus - membrane bound structure that contains the cell's hereditary information. * Nucleolus - structure within the nucleus that helps in the synthesis of ribosomes.
* Nucleopore - tiny hole within the nuclear membrane that allows nucleic acids and proteins to move into and out of the nucleus. * Ribosomes - consisting of RNA and proteins, ribosomes are responsible for protein assembly.
Plant Cell: Structures and Organelles
The following are examples of structures and organelles that can be found in typical plant cells:
* Cell (Plasma) Membrane - a thin, semi-permeable membrane that surrounds the cytoplasm of a cell, enclosing its contents.
* Cell Wall - outer covering of the cell that protects the plant cell and gives it shape.
* Chloroplasts - the sites of photosynthesis in a plant cell. They contain chlorophyll, a green pigment that absorbs energy from sunlight.
* Cytoplasm - gel-like substance within the cell membrane containing water, enzymes, salts, organelles, and various organic molecules.
* Cytoskeleton - a network of fibers throughout the cytoplasm that helps the cell maintain its shape and gives...
