I made tissues the biggest word because chapter 3 emphasized a lot on tissue and their special functions contribute to keeps the body working properly. The four types of tissues are epithelium, connective tissue, muscle tissue, and nervous tissue. Epithelium are classified by how many cell layers there are (simple and stratified) and the shape of the cells (squamous, cubodial, and columnar). (I also wanted to include the types of connective and muscle tissue, but that would have been too many words. :] ) Cells are what makes up tissues and organelles perform specific functions to keep the cells alive. One organelle, the nucleus, contain the chromosomes (DNA/genetic information) that have instructions for cell activities, like cell division (mitosis and cytokinesis) and protein synthesis. Protein synthesis involves ribonucleic acid (RNA) relaying messages/instructions, and transcription and translation (from base sequence into amino acid sequence). Cells also use passive transport, such as diffusion and osmosis, and active transport, such as solute pumping or bulk transport to get molecules they need for life. Membrane junctions (tight junctions, gap junctions, and desmosomes) are specializations of the plasma membrane of cells.
