| Question | Answer |
|---|---|
| What are the Life Processes? | There are 8 life processes that all living organisms must do in order to be considered alive |
| Reproduction | `Making new organisms of the same species |
| Respiration | Obtaining oxygen to combine with food to create energy |
| Regualtion | Sensing and responding to environmental stimuli |
| Excretion | The removal of metabolic waste |
| Growth | Increasing the size or number of cells in an organism |
| Nutrition | How an organism obtains its energy from its environment |
| Transport | The movement of essential materials and wastes through an organism |
| Synthesis | Combining two or more simple compounds to make more complex compounds |
| Metabolism | All chemical processes that sustain life by using all 8 life processes. Organisms either build or break down materials |
| Homeostasis | Maintenance of internal balance or a "steady state" within an organism DYNAMIC EQUALLIBRIUM |
| Prokaryotic | The first and most primitive cells they lack a nucleus and other membrane bound organelles such as a mitochondria. Bacteria are the ONLY prokaryotes |
| Eukaryotic | Most organisms have eukaryotic cells (ex: all plant and animal cells!) All genetic material is contained in a nucleus. They have many membrane bound organelles |
| Cell Membrane | provides a barrier between the cell and the environment |
| Mitochondria | where cellular respiration takes place, our energy comes from here! |
| Ribosomes | site of protein production. Endoplasmic Reticulum (ER): Transports materials around the cell. |
| Cell Wall | rigid structure around the outside of plant cells to give them structure and support. |
| Chloroplast | site of photosynthesis in plant cells, makes sugar molecules using sunlight, water and carbon dioxide. |
| Cellular transport | Active and passive one moves against the concentration gradient and one moves with the gradient |
| Inputs and outputs of photosynthesis | Light energy, CO2, and water O2 and glucose |
| Skeletal | stores minerals, provides support, structure, and protection |
| Muscular | aids in movement (voluntary and involuntary) |
| Nervous` | senses and responds to the environment, allows body-wide communication |
| Endocrine | body-wide communication to manage metabolism, growth, and reproduction |
| Immune | protection against foreign invaders |
| Digestive | breaks down food so it can be absorbed |
| Circulatory | transports almost everything (hormones, wastes, oxygen, wbc’s, etc) through the body |
| Respiratory | exchange of gases for cell respiration |
| Integumentary | barrier between us and environment |
| Excretory | removal of metabolic wastes |
