9. Which process usually uses carbon dioxide molecules?
A) cellular respiration
B) asexual reproduction
C) active transport
D) autotrophic nutrition

D) autotrophic nutrition

Explanation: Autotrophic nutrition is a type of nutrition in which a living organism manufacture its own food. For example, plants are autotrophs and they manufacture their own food using chlorophyll present in plant leaves to trap sunlight in the presence of carbon dioxide and water. This process is known as photosynthesis. In photosynthesis, plants use chlorophyll (a green pigment found in the Chloroplast of plant cells) to trap energy from the sun, in the presence of water and carbon dioxide to produce glucose and oxygen. The balanced chemical equation for photosynthesis is 6CO2 + 6H2O + solar energy --> C6H12O6 + 6O2.

a. seed plant structure. 1. the three main plant organs are roots, stems, and leaves. a fourth kind of tissue, meristematic tissue, is responsible for plant growth. meristematic tissue is the only plant tissue that produces new cells by mitosis. plants can lose water out of their leaves as they exchange gases with the air
