Comprehension Passage
Directions: Read the following paragraph and answer the questions below.
"Plant morphology examines the physical form and external structures of plants. This includes aspects such as leaf shape, root structure, and flower formation. Different plant species have evolved different morphological features suited to their environment. For example, cacti in arid environments have thick, fleshy stems to store water, and tiny leaves to minimize water loss through transpiration. Ferns in shady, humid environments have large, broad leaves to maximize photosynthesis. The study of plant morphology not only helps us understand how plants adapt to their environments but also aids in the identification and classification of plant species."

1
The study of plant diseases
2
The study of plant cell structure
