阅读下面短文,根据所读内容在表格中的空白处填入恰当的词。
注意:每个空格只填一个单词。
Fruit also makes up a flowering plant. It carries the seeds . The purpose of fruit is to protect a plant’s seeds and help them get spread about. Wind and water spread seeds .So do animals when they eat fruit and drop the seeds .
There are two main types of fruit: fleshy and dry. Fleshy fruits are soft and juicy , the way we usually think of fruits . Peaches ,plums ,and apples are all fleshy fruits . Dry fruits are thin and hard . Grains like wheat and rice , or nuts are dry fruits.
You’ve eaten seedless oranges and grapes . How can they be fruits? It’s because people have changed the way they grow fruit. They can now grow seedless fruit . Seedless fruit comes from special plants called hybrids(杂交生物体) . A hybrid is made by combining two varieties of a fruit to form a new variety . This hybrid grows and produces seeds . But the plants grown from these seeds are seedless . These plants cannot reproduce themselves.
A tomato is a vegetable , right? No , it’s actually a fruit . Other food we think of as vegetables—such as squash , peppers ,and eggplant—also are fruit . They’re fruit because they carry seeds and develop from flowers . Here’s another surprise . Scientists classify the tomato as a berry(浆果) . In addition , they don’t consider some fruits we call berries to be true berries because a berry is normally a type of fruit with a lot of seeds inside it . Technically , a strawberry , isn’t a berry , because it has its seeds on the outside . The red part is just the tip of the strawberry stem that’s enlarged.
Fruits are a source of nourishing(滋养) substances that keep us alive and healthy . For example , they contain many vitamins , especially vitamins A and C, and many minerals . They also provide fibre for a healthy digestive system and carbohydrates that the body needs to make energy.
