Auxin is a plant hormone produced in the shoot tip. Auxin causes cell elongation and travels down the stem from the tip. Auxin is destroyed by sunlight. Explain how this leads to positive phototropism in the plant. Correct Answer Auxin is broken down on the sunny side of the plant. Cells on the shaded side will elongate due to auxin, causing curvature of the stem so that the plant grows towards the light. Ivy plants often use walls or other plants as a support when growing. State the type of ...

Plant Tropisms Final Review Practice Questions 2024. tropism - ANSWER A growth response of a plant toward or away from a stimulus. geotropism - ANSWER A growth response to gravity. Negative geotropism is the plant stem growing up away from gravity. Positive would be the roots growing down toward force of gravity. thigmotropism - ANSWER plant growth in response to touch. Plant tendrils are wrapping around the stick. phototropism - ANSWER Plant growth in response to light. Positive phot...
