What is the difference between vascular and nonvascular plants? Give an example of each.

Vascular plants have specialized tissues that transport water, nutrients, and sugars throughout the plant, while nonvascular plants lack these tissues and rely on diffusion and osmosis to transport materials. An example of a vascular plant is a fern, while an example of a nonvascular plant is a moss.

Several types of tropisms include:

1. Phototropism: the growth or movement of a plant towards or away from light. This helps plants maximize their exposure to sunlight for photosynthesis.
2. Gravitropism: the growth response of plants to gravity, typically seen in roots growing downward and stems growing upward.
3. Thigmotropism: the growth or movement of a plant in response to touch or contact with a solid object.
4. Hydrotropism: the growth or movement of a plant towards or away from water, helping plants to access water in their environment.
5. Chemotropism: the growth or movement of a plant in response to chemicals in the environment, such as nutrients or toxins.
