Almost all living things get energy from light.

Directly: plants

Indirectly: animals

Photo synthesis

“to make with light”

CO2 + H2O C6H12O6 + O2

carbon dioxide + water glucose (sugar) + oxygen

Mitochondrion

C6H12O6 + O2 CO2 + H2O + energy

glucose + oxygen carbon dioxide + water + energy

Fermentation: energy is released without oxygen.

Cytokinesis

DNA is copied

preparation for division

Prophase Metaphase TelophaseAnaphase

chromosomes form

centrioles move/spindlefibers form

chromosomes line up in middle

chromosomes attach tospindle fiber

chromosomes split intochromatids

chromatidsbecome new chromosome

chromosomesmove to opposite ends

chromosomesstretch out

nuclear envelope forms
