A botanist studying the rate of photosynthesis analyzes the chemical composition of one leaf from each of several nearly identical plants. She than places each plant in a separate sealed, clear box containing a known composition of atmospheric gases and allows them to sit under carefully controlled lighting conditions. After a day, she analyzes the chemical composition of the atmosphere in each box and of another leaf from each plant.

Covering part of the box with cardboard
The carbohydrate that strenthens plant cell walls
What is Cellulose?

ESSAY QUESTION:
One of plants' main roles in nature is to provide food for animals and man. Explain how the function of each plant organ helps plants fulfill this role.
The plant organs are the leaves, stems, roots, and flowers.
Leaves produce food through photosynthesis. This food allows the plant to live and provides nutrients to animals or people who eat any edible part of the plant.
Stems support the leaves, ensuring that the leaves have the sunlight needed for photosynthesis. Stems also transport water and minerals from the roots to the leaves and transport food throughout the plant.
Roots absorb water and minerals and store food. The absorbed water and minerals are required for photosynthesis and for the life of the plant itself. If the root is edible (e.g., carrot roots) the stored food provides nutrients when the root is eaten.
Flowers allow plants to reproduce after their kind, ensuring that plants are abundantly available to produce food. Flowers also produce fruits, which animals and man can eat.

What is a Petiole?
