This document summarizes key processes in plant cells and how plants produce food. It discusses that plant cells contain organelles like the nucleus and chloroplasts which are not present in animal cells. Photosynthesis occurs in the chloroplasts and requires carbon dioxide, water, chlorophyll and sunlight to produce glucose and oxygen. The rate of photosynthesis is affected by the concentration of carbon dioxide, light intensity and temperature. Plants and animals are interdependent as plants produce oxygen for animals and animals produce the carbon dioxide needed for photosynthesis. The document also outlines how water and minerals are transported within plants and how transpiration occurs.
