This is a wood sorrel plant.
The stems keep the plant upright. Leaves and flowers grow on the stems.
Plant make food in their green leaves.

Some plants have leves that are sharp and spiky. They grow well as animals prefer to eat smooth leaves.
Lots of things you eat are plant parts. Broccoli is a bunch of lowers and carrots are a kind of root.
Underground, the roots soak up water from the soil. They hold teh plant in place too.

对于flower buds的感受，妈妈可以通过踏青给宝宝看桃花之类的春季鲜花的花蕾，这样宝宝一定有直观的感觉的
鲜花的组成可以通过观察盛开的花朵来介绍。。。相信春天大自然提供了我们很多很好的素材

记得小时候花坛里有很多称为一串红的植物，把花拔下来之后后面可以挤出甜甜的水。。可以用这个来给宝宝解释nectar。
花粉应该蛮容易演示的。。找一朵花，用餐巾纸擦一下就可以看到了。
不晓得有没有小蜜蜂采花蜜之类的绘本，可以结合起来给宝宝讲授粉的过程。。或者可以让宝宝也做一回小蜜蜂，替花朵授一下粉。。至于方法可以让小朋友动一下脑筋啦

妈妈们还可以和宝宝动手找一找每种植物的种子在哪里，街边的喇叭花，太阳花都是可以拿来做实例的教材。蒲公英更是一个又特别又好玩的example。可以让宝宝找一片开阔的地方，帮蒲公英的种子找到自己的家

第七讲：Spreading Seeds
各种种子的形态，妈妈可以通过实物来解释，比如用苍耳的种子来介绍那些带刺的种子，相信妈妈们都有小时候从衣服上往下拔苍耳种子的经验。

Another famous one is the birdof paradise flower (on the photo above). Hibiscus have beautiful big flowers. Other amazing flowers of rainforests are flamingo flowers, lotus flowers, and in Australian rainforests - grevilleas, garnedias and silky oaks.
And some of the more interesting are the carnivorous pitcher plants, and the rafflesia flower- the largest flower in the world.

炎热干旱的沙漠里面也有花么？在前面宝宝们知道了植物的生长需要水，沙漠里面缺乏的是水，植物们是如何各项神通来获得水分的呢。
这一章可以稍微衍生一下，先让宝宝发挥一下想象力，植物如何利用有限的水分来生长的。
最容易的例子就是总所周知的仙人掌了。
找到一些有趣的对仙人掌的描述：
About cacti
Most plants get rid of litres of water every day, by a process called transpiration, giving out water through their leaves (a bit like when we sweat!). Cactus leaves have become a lot smaller so they don't lose so much water; most have shrunk to spines or hairs but some have disappeared altogether!
The stems are green to make food for the plant, because the leaves can't do it any more - they are too small.
Cacti stems and ridges expand to store lots of water when it rains. Think of a camel that stores food in his hump! This guides as much rain as possible to the roots. Some cacti and succulents have swollen roots that store up water for the days when it doesn't rain; sometimes in the desert it doesn't rain for months
Leaf succulents
Leaf succulents store water in their leaves. Their leaves can take different forms as a means of protection from drying out. They can be:
- hairy or waxy
- covered in a white 'bloom'
- silvery-grey in colour
Interesting facts
The giant saguaro cactus is:
- The tallest cactus in the world, growing up to 20m (67ft) high.
- It can weigh up to six tonnes, which is mainly the weight of the stored water.
- Some of these cacti are 250 years old.
- The Gila woodpecker nests inside the stem of the saguaro cactus where the temperature inside can be up to 30ºC (86ºF) cooler than outside.
The ocotillo plant only grows leaves after it has rained - as soon as the soil dries out, they all drop off.
Some cacti spines are nearly 15cm (6in) long.
Boerhavia repens is a desert plant which can germinate, grow, produce flowers and ripen seeds in the space of ten days after it has rained.
The century plant takes 25 years to grow a flower. Then it dies. Lots of agaves do this!
Pebble plants (Lithops species) only have two leaves, and they look like the pebbles on the ground next to the plant. Their beautiful flower grows between the leaves.
Some species of agave plants (succulents not cacti) are also called Needle and Thread plants because the spiny tip and stringy leaf margin can be broken off and used to sew - and are even strong enough to sew through leather.
The spines of the Barrel cactus were used by local people for fishing hooks.
Desert wild flowers. These flowers bloom after a rain, then die within a matter of days. That is the example of this life.

这个比较容易找实例，睡莲，荷花都是大家很常见的。。可以让宝宝猜一猜荷花的根是什么，可以引出lotus root的概念，可以问一下为啥藕这么多洞的
查了下water plant 的特征：
Characteristics
Characteristics of aquatic plants:
- A thin cuticle. Thick cuticles reduce water loss; thus most hydrophytes have no need for thick cuticles.
- Stomata that are open most of the time, because water is abundant and there is no need for it to be retained in the plant. This means that guard cells on the stomata are generally inactive.
- An increased number of stomata, which can be on either side of the leaves.
- A less rigid structure: water pressure supports them.
- Flat leaves on surface plants for flotation.
- Air sacs for flotation.
- Smaller roots: water can travel directly into leaves through osmosis; thus large root systems are not required for water uptake.
- Feathery roots: no need to support the plant.
- Specialized roots able to take in oxygen.
Wide flat leaves in water lilies (family Nymphaeaceae) help distribute weight over a large area, thus helping them float near surface.
Many fish keepers keep aquatic plants in their tanks to control phytoplankton and moss by removing metabolites.
Many species of aquatic plant are invasive species. Aquatic plants make particularly good weeds because they reproduce vegetatively from fragments.

里面提到了几种植物：
1）Venus Flytrap 捕蝇草
下面这个网页很详细的介绍了捕蝇草
http://www.botany.org/bsa/misc/carn.html
2）Sundew plants
SundewsSundews are a genus of carnivorous plants which usually live in wet habitats where the acidic conditions limit the amount of nutrients they can extract from the soil. These plants therefore supplement their diet by catching and digesting small creatures such as insects. Some species of sundew are very long-lived. Sundews can be found growing on every continent except Antarctica.

19号团里面有一本how flowers grow,正好迎合3月活动，拿出来和大家共享阿
第一讲，Seeds to seedlings
A seed has a hard shell with a young plant inside. Seeds grow in the soil when the sun and rain has made them warm and wet.
(秀宝宝几颗瓜子，最好是生的）These are sunflower sheeds. Each sunflower seed can grow into a big sunflower. (可以秀宝宝向日葵图片 who is hiding in the garden 里面也有的）

1) In the soil, the shell of a seed splits.
2) A small root sprouts out of it
3) Then a shoot grows out of the seed

When a shoot breks through the soil, it is called a seedling.
The largest seed in the world is teh coco de mer. It is bigger than a football.
