Make a list of several foods we usually call vegetables that reacts with water s being used in were picked are actually fruits. What is the definition of a fruit you used in your list? nswer these e ripening? (2) Is chain? 2. If wind and insects carry pollen from several flower species 3. Many flowers have both anthers and pistils. What prevents 4. What is the advantage of outcrossing in sexual reproduction? at the same time, why doesn't the pollen of one species fertilize the eggs of a second species, thus forming hybrids? self pollination and later self-fertilization? Many fruits are harvested before they ripen and then are treated S. with ethylene gas just before they are shipped to stores. Why? mation, t formation in 6. Would a plant be able to grow to maturity and produce seeds if kept in total darkness? Why?Explanation / Answer
1. Many spices like grasses, maples, oaks and many others, are pollinated by wind. Whereas pollination by the insects involves bees which are the most important insect pollinator of many plants (garden plants) and many trees which are commercially produced. Hence, different species of the plants are pollinated by the different sources that's why the pollen of the one spices cannot fertilize with eggs of the second spices.
2. The plants which are harvested before the ripening because after harvesting fruit and many vegetables stop producing organic compounds and become dormant. Fruits and many vegetables ripen continue till senescence and the rate respiration is directly related to perishability of the fruits and most of the vegetables.
Many fruits are harvested before they ripen and then treated with the ripening hormones such as ethylene gas just before shipped to avoid the rottening of the fruit and makes the fruits for higher playability, seems fresh by appearance.
