Question

1. a forest restoration team is studying how two types of seeds spread to new locations. they release an acorn and a dandelion seed from the same height on a windy day and observe how each one moves and where each one lands. using what you know about seed structures and the advantages they give plants, which explanation best describes why the dandelion seed may reach a more successful growing location than the acorn? its lightweight, parachute - like structure allows it to stay aloft longer and travel farther before landing its bright color helps attract animals that can carry it to new locations more easily than an acorn. its heavier structure helps it drop straight down into soil that is more likely to support germination. its hard outer covering protects it from wind, allowing it to avoid drifting too far from the parent plant. clear all

Explanation:

To determine why the dandelion seed may reach a more successful growing location than the acorn, we analyze each option:

• Option 1 (bright color attracting animals): Dandelion seeds are not spread by animal attraction for this purpose; acorns are more likely spread by animals. Eliminate.
• Option 2 (heavier structure for germination): Dandelion seeds are lightweight, not heavier. Acorns are heavier. Eliminate.
• Option 3 (hard covering preventing drifting): Dandelion seeds are designed to drift via wind; the hard covering description doesn't fit. Eliminate.
• Option 4 (lightweight, parachute - like structure): Dandelion seeds have a parachute - like structure (pappus) that is lightweight. This structure allows them to be carried by the wind for longer distances, increasing the chance of finding a suitable growing location. Acorns are heavy and fall straight down, limiting their spread. This matches the seed structure and dispersal advantage.

Answer:

The correct option is: Its lightweight, parachute - like structure allows it to stay airborne longer and travel farther before landing.
