Questions 36-38:
A botanist studying the rate of photosynthesis analyzes the chemical composition of one leaf from each of several nearly identical plants. She then places each plant in a separate sealed box containing a known composition of atomospheric gases and allows then to sit under carefully controlled lighting conditions. After a day, she analyzes the chemical composition of the atomosphere in each box and of another leaf from each plant. What change would most likely affect the rate of photosynthesis? |
covering part of the box with carboard
|
|
|

The leaf naturally contains blue and yellow pigments that are masked by the presence of green chlorophyll. |

|
|
stalk that attaches leaf to stem |

ESSAY: Write a paragraph and defend the following statement: God designed each organ of a flowering plant to help the plant fulfill its role in nature. |
God made plants to provide food for other organisms. All food consumed by humans and animals comes directly or indirectly from plants. Plants have many other uses like making carbohydrates and oxygen. Leaves absorb the light from the sun and takes in carbon dioxide to produce food for the plant through photosynthesis. The food allows the plant to live, so it can provide nutrients to any human or animal that eat any part of the plant. The roots help anchor the plant in the soil and help bind the soil together to help prevent soil erosion. Roots also absorb the water the leaves need for photosynthesis. Stems transports water and nutrients throughout the plant, helps hold its leaves above the ground so they can get more sunlight, provides homes for animals, and wood and other supplies for humans. Flowers produce nectar and fruits that humans and animals eat.Flowers allow plants to reproduce more flowers like them through pollination, so they can always be available for their role in nature. Flowers produce nectar and fruits that humans and animals eat. |
