Download Energy: Endothermic vs. Exothermic Notes

Processes in
Plant & Animal
Cells
TEKS 7.5.A recognize that radiant energy from the sun is
transformed into chemical energy through the process of
photosynthesis
TEKS 7.7B illustrate the transformation of energy within an organism
such as the transfer from chemical energy to heat energy and
thermal energy in digestion
Process name:
