Which process explains why aphids feeding on phloem experience a rapid influx of sugar, resulting in honeydew excretion?

💡 Explanation

Aphids experience rapid sugar influx because pressure flow transports sugars from source (leaves) to sink (aphid's stylet in phloem) due to hydrostatic pressure differences. Therefore, pressure flow loading is the correct answer, rather than osmosis or active transport, which are slower or operate on different cell types.
