Final answer:
Triangle congruence can be proven using postulates such as SSS, SAS, ASA, AAS, or HL. Leaves are adapted for photosynthesis by having a large surface area, thin structure, and containing chlorophyll in chloroplasts. They play a crucial role in capturing light energy and producing glucose and oxygen.
Step-by-step explanation:
The triangle congruence postulate or theorem used to prove each pair of triangles congruent could be Side-Side-Side (SSS), Side-Angle-Side (SAS), Angle-Side-Angle (ASA), Angle-Angle-Side (AAS), or Hypotenuse-Leg (HL) for right triangles. If there is not enough information to use one of these postulates or theorems, then congruence cannot be proven, and we write NP for not possible. If congruence can be proven, we then write the correct congruence statement (e.g., ΔABC ≈ ΔXYZ). Regarding photosynthesis, plant leaves are adapted in three main ways: large surface area to capture more sunlight, thin structure to facilitate gas exchange, and the presence of chlorophyll in chloroplasts for efficient light absorption.
Role of Leaves in Photosynthesis
Leaves are the primary site of photosynthesis in plants. They capture light energy and convert carbon dioxide and water into glucose and oxygen, which are essential for the plant's growth and are also released into the environment as byproducts that benefit other organisms. Essential structures involved in this process include the chloroplasts, stomata, and mesophyll cells.
