Life Processes Guided Notes Name: _________________________ Date: ________ What are life processes? _______________________________________________________________________________________________________________________________________________________________________________________ The official life processes are:

1. __________________________ 2. __________________________ 3. __________________________ 4. __________________________ 5. __________________________ 6. __________________________ 7. __________________________ 8. __________________________

Transport Multicellular organisms must transport __________________ to all cells and remove wastes from those cells.

Humans use our blood stream, or circulatory system, while single cells use an intracellular network in the ____________________ made of microtubules.

Respiration Respiration is ___________________________ ____________________________

The______________________ is where this happens. Most life forms receive energy from glucose (sugar). Some can form ATP from glucose using Oxygen and others form ATP from glucose without using oxygen. Dou you know the difference between aerobic respiration and anaerobic respiration? Excretion

Getting rid of_____________. You know how we get rid of wastes. Single-celled organisms and single cells use exocytosis and membrane transport. Synthesis

Building __________________from ___________________for growing or maintenance.

Humans synthesize new cells all the time, like our skin cells. We also make new cells as we grow. Single-celled organisms and single cells make new proteins in the ___________________.

Regulation

A response to__________________________, or homeostasis.

We drink water when it is hot out to replace water we are loosing. Single cells respond to heat by also absorbing more water. There are many examples of regulation. Can you think of one? Growth Growth is _____________________ ___________________________________ ___________________________________ This is made possible by synthesis. We

grow by making new cells while protozoa and other single-celled organisms grow by just getting bigger. Reproduction Producing more of the same kind. All living things have the drive to reproduce.

From bacteria to humans, reproduction is built into our genetics. This is the only life process that individuals do not need to survive. Nutrition

Nutrition is ______________________________ _______________________________.

We and other organisms obtain food by eating. This is called ___________________nutrition. Plants make their food during photosynthesis in the chloroplasts. This is called ____________________ nutrition.
