7-2 Notes Eukaryotic Cells 1. Eukaryote cells are divided into two parts Nucleus Cytoplasm Portion outside the nucleus where organelles reside Nucleus 2. Contains most of the cell’s DNA 3. DNA is the code for making proteins 4. Surrounded by a double membrane called the nuclear envelope 5. Contains chromatic‚ which consists of DNA bound to protein Condenses during cell division to form chromosomes 6. Nucleolus – small dense region in nucleus where the assembly of ribosomes begins Ribosomes 7. Small

What is passive transport? Passive transport is the movement of substances across the cell membrane without the use of energy by the cell. During passive transport‚ substances move down their concentration gradient‚ hence no energy is required. Passive transports can happen through three different channels‚ namely 1. lipid bilayer 2. pore protein 3. carrier protein SIMPLE DIFFUSION What is diffusion? Diffusion is the movement of particles from a high density region to a low
