Name process responsible for absorption of materials by aquatic animals
Answers
Answer:
Explanation:
the process of producing food with the help of light energy remains the same for both aquatic and land plants. In addition to light, they require the basic raw materials - carbon dioxide (CO2) and water (H2O) for synthesis of glucose (C6H12O6).
In case of land plants, the required gases and light energy are available easily. They absorb carbon dioxide from atmospheric air through their stomatal openings (present in upper and lower side of leaves), water from the soil through their root system, and last but not the least, radiant energy from sunlight. Hence, land plants undergo photosynthesis naturally without any special adaptations.
Since water is available in more than sufficient amounts, the major challenge is to obtain carbon dioxide and light. For the same, majority of these plants show adaptations in some way or the other. Say for example, water lily (lotus) bear floating leaves with waxy surface, which have extra long petioles. The leaves on the surface of water gather light and carbon dioxide for photosynthesis, while the waxy cuticle prevents excess water absorption from the surrounding environment. It also helps in cleaning process and preventing entry of microbes.
