HLSC 1200U Lecture Notes - Lecture 1: Homeostasis, Organelle, Organism
Document Summary
Science of the structure of an organism and the relationship of its parts. Anatomical structures often seem designed to perform specific functions due to their size, shape, form, or body location. Function of an organism and the relationship of its parts. Understand the interaction between the two as they assist in the integration of information: chemical level basis for life. Organization of chemical structures separates living material from non-living. Such as, atoms, molecules and macromolecules results in living matter known as: cytoplasm: organelle level. Structures organized to form organelles that perform individual functions. Allow for cells to live: cellular level. Smallest and most numerous units that displays the characteristic of life. Each cell has a nucleus surrounded by cytoplasm within a limiting membrane. Cells are different to perform different function: tissue level. Organization of similar cells specialized to perform a certain function. Tissue cells are surrounded by non-living matrix: organ level.
