Light harvesting pigments are found in the thylakoids of mitochondria. The ribosomes of eukaryotes differ in size from those of prokaryotes. The Golgi apparatus is a series of flattened membrane sacs where some newly synthesized proteins are modified. The cytoskeleton is a dynamic structure. All organisms are composed of cells.
All cells come from pre-existing cells.
The cell is the basic unit of life. Some cells, like intestinal cells, increase their cell surface to volume ration by having cellular extensions called microvilli. The Golgi apparatus consists of many layers of flattened membrane sacs. Peroxisomes are sometimes present in plant and animal cells. Vesicles move the contents of the endoplasmic reticulum to the Golgi and from the Golgi to other parts of the cell, including the plasma membrane.
