Question

use the text to compare and contrast hybrid plants and heirloom plants.

when planting a vegetable garden, gardeners might choose hybrid plants or heirloom plants. a hybrid vegetable is created when plant breeders cross - pollinate two different varieties of a plant to produce a vegetable containing the best traits. in the case of heirlooms, the plants are open - pollinated, which means insects or the wind—not plant breeders—pollinate the plants. unlike hybrid plants, which are being created all the time, a plant variety typically has to be at least fifty years old to be considered an heirloom. many gardeners claim that heirlooms have a better taste than hybrids. so why do people plant hybrids? hybrid plants usually yield vegetables that are ready to harvest at the same time. the vegetables also tend to have a uniform appearance. on the other hand, heirloom vegetables may ripen at different times, and their size may vary.

	hybrid plants	heirloom plants
usually at least fifty years old
have a uniform appearance
harvest times may vary

Explanation:

To solve this, we analyze the text for each characteristic:

1. Are open - pollinated

From the text: "In the case of heirlooms, the plants are open - pollinated...". Hybrid plants are cross - pollinated by breeders. So this characteristic belongs to heirloom plants.

2. Usually at least fifty years old

The text states: "a plant variety typically has to be at least fifty years old to be considered an heirloom". Hybrid plants are "being created all the time" so they don't have this age requirement. Thus, this is for heirloom plants.

3. Have a uniform appearance

The text says: "The vegetables (from hybrid plants) also tend to have a uniform appearance". Heirloom vegetables may have varying sizes and ripening times. So this is for hybrid plants.

4. Harvest times may vary

The text mentions: "heirloom vegetables may ripen at different times". Hybrid plants have vegetables ready to harvest at the same time. So this is for heirloom plants.
