It's because pterophytes are vascular plants that contains vascular tissues which support growth. Bryophytes are nonvascular plants, they don't have vascular tissues that's why it doesn't grow too large.

Structural, because structural adaptation is adjustments to internal or external physical structures (texture color etc.). Camouflage is any coloring shape or pattern that allows an organism to blend in.
one adaptation is the color of its flesh camouflage with seaweed.
A structural adaptation is a physical trait that allows an organism to survive or reproduce like fur to keep warm or tusks to keep predators away. A swan has wings. Wings are a physical trait that allow swans to escape from predators, thus allowing them to survive.
Adaptation or adaptive value is any genetically controlled structural, physiological, or behavioral characteristic. This helps an organism survive and reproduce under a given set of environmental conditions.
A structural adaptation of the western spiderwort is its long, thin leaves that help to maximize sunlight absorption for photosynthesis. Its deep root system allows it to access water and nutrients efficiently in dry environments. Additionally, its small size and slender stems help it withstand windy conditions.
This structural adaptation is called mimicry. Mimicry allows an organism to closely resemble a harmful species in order to gain protection from predators that avoid the harmful species. By mimicking the warning signals or appearance of a harmful species, the mimicking organism can deter predators and increase its chances of survival.
The glowing tail of a firefly is a physical adaptation. Fireflies produce light through a process called bioluminescence, which is a chemical reaction that allows them to emit light. This adaptation helps fireflies to attract mates, warn predators, and communicate with each other.
Salt glands in saltwater crocodiles are structural adaptations. These glands are specialized organs that help the crocodile get rid of excess salt from its body when living in a salty environment, such as the ocean or saltwater habitats. This adaptation allows saltwater crocodiles to maintain a healthy balance of salts in their bodies and survive in their environment.
A structural adaptation of the Sea Turtle are their forelimbs and neck, the forelimbs are modified into long, paddle-like flippers for swimming, it allows the Green Turtle to maintain its speed whilst travelling in the ocean.
Adaptation does not allow for natural selection: natural selection causes adaptation.
A structural adaptation of the deodar tree (Cedrus deodara) is its needle-like leaves, which reduce water loss through transpiration. These leaves have a waxy coating that helps retain moisture, making the tree well-suited for its native mountainous habitats. Additionally, the tree's conical shape allows snow to slide off easily, preventing branch breakage in heavy snowfall.
