Answer: 1st part Because plants cannot walk around and take their seeds to other places, they have developed other methods to disperse (move) their seeds. The most common methods are wind, water, animals, explosion and fire

2nd part  plant tropisms are mechanisms by which plants adapt to environmental changes. Thigmotropism describes plant growth in response to touch or contact with a solid object. Positive thigmostropism is demonstrated by climbing plants or vines, which have specialized structures called tendrils. Gravitropism or geotropism is growth in response to gravity.

Answer:

2)During photosynthesis, plants take the water from the soil, and the carbon dioxide from the air, and they make sugars out of it. When plants have the right balance of water, air, sunlight and nutrients, their cells grow and divide, and the whole plant gets bigger and bigger. And that's how plants grow.

Phototropism is the orientation of a plant or other organism in response to light, either toward the source of light.

Thigmotropism is the turning or bending of a plant or other organism in response to a touch stimulus.

Gravitropism is a coordinated process of differential growth by a plant in response to gravity pulling on it.
