Question

9 which pigments can be found in deciduous leaves? what color does each create? 10 write the equation for photosynthesis using both words and molecules. 11 how does chemosynthesis differ from photosynthesis? 12 explain why plants appear green to your eye.

Explanation:

Step1: Answer question 9

Chlorophyll (green), carotenoids (yellow - orange), anthocyanins (red - purple). Chlorophyll gives green color, carotenoids give yellow - orange color, anthocyanins give red - purple color.

Step2: Answer question 10

Words: Carbon dioxide + water + light energy → glucose + oxygen. Molecules: $6CO_2 + 6H_2O+light\ energy
ightarrow C_6H_{12}O_6 + 6O_2$.

Step3: Answer question 11

Photosynthesis uses light energy to convert carbon - dioxide and water into glucose and oxygen. Chemosynthesis uses chemical energy (from inorganic compounds like hydrogen sulfide) to produce organic compounds, without the need for light.

Step4: Answer question 12

Plants appear green because chlorophyll in plant cells absorbs most of the red and blue light in the visible spectrum, but reflects green light. Our eyes detect this reflected green light.

Answer:

1. Chlorophyll (green), carotenoids (yellow - orange), anthocyanins (red - purple).
2. Words: Carbon dioxide + water + light energy → glucose + oxygen. Molecules: $6CO_2 + 6H_2O+light\ energy

ightarrow C_6H_{12}O_6 + 6O_2$.

1. Photosynthesis uses light energy, chemosynthesis uses chemical energy from inorganic compounds.
2. Chlorophyll reflects green light which our eyes detect.
