Nucleus Chromatin- DNA and protein make up the chromosomes Nucleolus- site of the ribosome assembly Nuclear envelope with nuclear pores Cytoplasm-has a fluid component that all organisms suspended in the cytosol Endomembrane System Plasma membrane Nuclear envelope Endoplasmic reticulum 1. Rough ER-ribosomes attached to membranes to cytosolic side 2. Smooth ER 3. Lumen=internal space (some proteins are made and pushed through) Golgi complex-packages processes proteins cells made by ER. ..Vesicles Vesicles-little membraneous structures(bubbles) Lysosomes- built by Golgi complex . .no internal structures 1. Apoptosis- programmed cell path 2. Necrosis- unprogrammed cell path Vacuoles 1. versatile 2. apoptosis in plant cells 3. plant cells accumulate waste in vacuoles, makes bitter taste Mitochondria Aerobic cellular respiration Food +oxygen>ATP+carbon dioxide+water
