Honors Bio Life Functions

Regulation

Regulation

control and coordination of physiological activities

Synthesis

forming a complex molecule from simple molecules

Respiration

release of stored energy from an organic molecule transfer of chemical energy to a more usable form

Transport

Life function by which organisms absorb and distribute materials needed for life.

Nutrition

the processes by which living organisms obtain and use those acquired nutrients to sustain biological life.

Digestion

break down of food into nutrients

Reproduction

process performed by organisms to repopulate their species

Locomotion

helps us to move from one place to other

Homeostasis

the balance of all your life functions

Metabolism

the sum of all your life functions

Cells

sequence of levels of structural organization

Unicellular

composed of one cell, perform life processes without organ systems

Multicellular

composed of many cells, perform life processes with organ systems

The factors required to be considered as a living thing

1. perform metabolic processes

2. maintain homeostasis

3. needs energy for cell activities

4. composed of one or more cells

What are all the six organelles?

nucleus, mitochondria, chloroplast, cell membrane, ribosomes, vacuoles

Nucleus

controls most cell activities and contains DNA

Mitochondria

site of aerobic cellular respiration

Chloroplast

site of photosynthesis

Cell membrane

selectively regulates the passage of materials into and out of the cell

Ribosome

site of protein synthesis

Vacuoles

storage of waste, food, and excess water

Lysosome

an organelle that helps digest certain materials inside the cell.

Amyloplast

colorless plant plastid that forms and stores starch.

golgi body

takes in protein, modifies it, and then places it in cells called vesicles

endoplasmic reticulum

a network of membranes in a cell through which molecules like proteins move in.

nucleolus

a sphere whose function is to produce and make the cell's ribosomes.

nuclear envelope

membrane barrier that separates the nucleus from the cytoplasm.

cytoplasm

holds the components of the cell and protects them

centriole

help with cell division in animal cells.
