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...
