AP BIOLOGY

Detailed explanation-1: -Sunlight, water and carbon dioxide are the raw materials; food and oxygen are the products of photosynthesis.

Detailed explanation-2: -The raw materials required for aerobic cellular respiration are respiratory substrates (glucose, fatty acids, amino acids, or organic acids) and oxygen but in the case of anaerobic respiration raw material is respiratory substrate only.

Detailed explanation-3: -The raw materials of photosynthesis, water and carbon dioxide, enter the cells of the leaf. Oxygen, a by-product of photosynthesis, and water vapor exit the leaf. In most land plants, water enters the roots and is transported up to the leaves through specialized cells known as xylem (pronounced zigh-lem).
