Question

cells obtain the energy and materials they need to grow, divide, and carry on the functions essential to life from
a. water
b. sunlight
c. food
d. air

Explanation:

Cells need energy and materials for life processes. Food (which contains nutrients and energy - rich molecules like glucose) is the source from which cells obtain the energy (through processes like cellular respiration) and materials (like carbon, nitrogen, etc. for building molecules) they need to grow, divide, and perform life - essential functions. Water is important for many cellular processes but is not the primary source of energy and building materials. Sunlight is used by autotrophic cells (like plant cells) to make food during photosynthesis, but the cells obtain energy and materials from the food (either made or consumed), not directly from sunlight. Air provides oxygen for respiration but not the full range of materials and energy like food does.

Answer:

C. food
