Alright, so we all know that person
好吧!所以我們都認識那個
who, every time you say anything,
每當你說些什麼
they're like "Actually, technically, tomatoes aren't vegetables!"
就會說「事實上,技術上來說,蕃茄不是蔬菜!」的人
And... I just.. before we do this episode,
且...我只是...在我們開始做這集之前
I just want to encourage you not to be that person
我只是想要鼓勵你不要成為那樣的人
But, knowing the real classifications of the stuff that we eat
但是,知道我們所吃的東西的真正分類
can tell you a lot about where fruits and vegetables
可以讓你知道更多食物跟蔬菜到底來自哪裡
come from and how they're developed.
以及他們是怎麼生長的
So it's pretty interesting
所以還蠻有趣的
just don't use it to be an insufferable pedant.
但不要把這些知識用於當一位惹人厭的嘴砲王
For example, officially speaking,
例如,依照正式的分類
Anything that is a root, stem or leaf of a plant
任何植物的根莖葉部分
qualifies as a vegetable.
都被認定是蔬菜
meaning that some things that you might ordinarily
也就是說,有些你一般認為
consider a fruit, is actually a vegetable.
是水果的東西,其實是蔬菜
Rhubarb, for instance, we think of a
大黃,例如,我們覺得是一種
kind of like a fruity thing because
像是水果般的東西,因為
it's in pie and it tastes so sweet
在派裡面且嚐起來很甜
but it's the stalk of a plant, so its a vegetable.
但他是植物的莖,所以他是蔬菜
Vegetable pie...who thought of that?
蔬菜派...誰會想到這個啊?
Corn, zucchini, and green beans, on the other hand
另一方面,玉米、密生西葫蘆(夏季的一種南瓜)和綠豆
all fruit, so are tomatoes.
都是水果,番茄也是
That's because these foods are not
因為這些食物不是
roots, stems, or leaves.
根、莖或葉子
They're ovaries.
他們是果實(子房)
Hopefully that doesn't make you feel too weird.
希望這不會讓你覺得太奇怪
So yeah, fruits are the ovaries of a flowering plant
好吧!水果是開花植物的果實(子房)
that develop after its seeds are fertilized
是種子受精後開始生長而成的
or, sometimes, after they've been triggered to
或者,有時候,他們被觸發而
develop without fertilization.
未受精就生長了
From the plant's perspective, surrounding its seeds
就植物來說,在其種子周圍
with something soft and juicy and delicious
有一些軟軟、多汁跟美味的(部分)
increases the chances that those seeds will get eaten
會增加種子被吃的機會
and then spread around in nice fertile
然後被散播在肥沃(營養)的
piles of poo.
大便堆旁。
So broccoli and cauliflower are not fruit
所以花椰菜不是水果
even though they are flower buds because they're unopened
即便他們是花蕊,但因為他們還沒開花
the flower hasn't transformed.
花還沒有變化
True fruits come in lots of different types
真的水果有很多種形態
and some of them make for excellent anatomy lessons
其中有些有利於作為超棒的解剖學課程
One key factor for botanists in categorizing fruits is
對植物學家來說,在分類水果時有一個關鍵因素是
is how many ovaries the flower had.
這朵花有多少個子房
So berries by definition are fruits that come from
所以根據定義,漿果是
from a single ovary with multiple seeds.
來自一個有很多種子的子房的水果
That makes grapes, bananas, peppers and tomatoes
這讓葡萄、香蕉、胡椒跟番茄
all different types of berries.
都被定義為莓果,只是型態不同
So hold onto your shorts because raspberries
所以抓好你的褲子,因為覆盆子
and blackberries are something totally different
跟黑莓是完全不一樣的東西
They're called aggregate fruits
他們被稱作聚合果
a whole bunch of little fruits grouped together.
一堆小水果聚集在一起
And strawberries aren't berries either
且草莓也不是漿果類的
in fact, the tasty red part of the strawberry isn't
事實上,草莓的紅色可食用部分甚至不是
even a fruit. Its a special kind of plant structure
一種水果。它是一種植物的特殊結構
called a fleshy receptacle.
叫做肉體花托
You actually have to look much closer at the receptacle
事實上,你必須更靠近一點去看花托
to see the fruit, which are called achenes.
才能看到真正的水果,也被稱為瘦果
They're dry, one-seeded fruits that speckle
瘦果是乾燥,只含有一顆種子的水果
the red surface of the strawberry
並散布在草莓的紅色表面
Sunflowers produce another achene that you probably
向日葵製造另一種瘦果,你可能
know as sunflower seeds.
認識並稱它為向日葵種子(葵瓜子)。
Nuts are fruits too and their shells are coats
堅果也是水果,且他們硬殼
developed from the ovary wall.
是從子房壁發展而來的
That includes things like chestnuts and hazelnuts
這個種類就包含像是栗子跟榛果
But technically, walnuts and pecans are not nuts,
但技術上來說,胡桃跟山胡桃不是堅果類
along with other single ovary fruits like peaches and
連同其他單子房水果,像是桃子跟
and plums and coconuts, they're called drupes.
李子跟椰子一樣,他們被稱作是核果
Drupes only have one seed with a distinct skin,
核果只有一個有著獨特外皮的種子
covering a fleshy middle layer.
覆蓋在多肉的中層
In a drupe, the inner layer is often called stone-like,
在核果中,最內層通成被稱作為如石頭一般
and if you've ever accidentally chomped on a peach pit,
如果你曾經不小心咬了桃子的內核
you understand why.
你會知道為什麼
Now if you want to get super fancy with your botanical terminology
現在,如果你想要用你的植物學術語來耍花樣
raspberries and blackberries are specifically
樹莓跟黑莓在類別上特別是
aggregate drupes, and each small section is called a druplet.
聚集核果,每一小部分稱作小核果
But many fruits are more than just a ripened flower ovary.
但很多水果都不只是個成熟的花子房
Take pome fruits, for instance, like apples and pears.
例如梨果類,就像蘋果跟梨子
Pome fruits are known as accessory fruits because
梨果類水果被視作是假果,因為
there's so much more going on in them than a simple ovary
他們不只是區區的一個子房
The ovary makes up only the core of the fruit.
子房僅能夠長成果核
The flesh of the fruit is actually modified
果肉其實是變形的
flower petals and sepals, the flower parts that cover a bud
花瓣和萼片,即是覆蓋花蕾的構造
and even the knobby receptacle at the base of the flower.
甚至是花朵底部多節的花托也會長成果肉
And when you eat hesperidium fruits
且當你吃柑橘果類水果時
you're also getting a mouthful of the unexpected
你其實是滿口的未知
This category includes fruits with tough rinds
這分類包括了據有粗糙外皮
and little partitions, like lemons and grapefruits
和一瓣瓣果肉的水果,像是檸檬跟葡萄柚
and oranges. Turns out that those small packed together
以及橘子。那些聚集起來,小小滿是
juicy bits in each section, called juice sacs
多汁的果粒被叫做果汁袋
were once tiny hair like cells on the inside of the ovary,
原來,這些果汁袋曾經是在子房內像毛髮般的微小細胞
but they filled bursting with goodness as the fruit ripened.
但隨著果實成熟,他們充滿了精華
So the next time you drink a pulpy glass of OJ
所以下次你在喝一杯多果肉的橘子汁時(Orange Juice)
enjoy your mouthful of fruit hair.
好好享受滿嘴的果肉毛髮吧
