  植物的英语作文【篇一】

  I want to kind of beans, mung beans, because every time I eat soy milk in thought, if I can kind of soybean and green bean, I can use my kind of soybean and green bean got the soya-bean milk. I am at home to take a flower pot, flower pot is white. I take out your home soil again.

  I took out my beans and green beans hold in hand, cool, then carefully put the seeds buried in the ground, I can not wait to long it out, I water the seed every day, fertilization. Seeds may sometimes speak in soil in the mother's arms, possible soil mother tell her: "the outside world can be beautiful, peach blossom smile red in the face and shook the willows green long braids, chattering swallow."

  A day after day... Every day I good care of in the seed. One day, he finally break out? I am a 磞 high, hurry to call mom and dad, mom and dad was very happy! Day after day... A pot of beans grow back, just can't see mungbean sprout. Green beans are also in sleep late? Long after I from day to day care, finally out! May be of women and children call to wake the birds and spring? I know that the teacher asked us to write the composition is why? Because the teacher wanted us to know a few seed is so difficult, but mother raise us even harder. I must repay the mother.

  Although my seeds grow back, but there are students of plant is better than mine. I want to take good care of my little better sprouts.

  我想种黄豆、绿豆,因为我每次吃豆浆的时候都在想,如果我能种黄豆和绿豆的话,我就可以用我种的黄豆和绿豆打豆浆了。我就在家里拿了一个花盆,花盆是白色的。我又把家里的土拿出来。

  我拿出黄豆和绿豆捧在手上,冰凉的,再把种子小心翼翼的埋在土里,我就迫不急待的想要它长出来,我每天给种子浇水、施肥。种子也许有时还在土壤妈妈的怀抱里说话,可能土壤妈妈在告诉她:“外面的世界可美丽了,桃花笑红了脸,柳树摇着绿色的长辫子,小燕子叽叽喳喳地叫着。”

  过了一天又一天……每天我都在细心的照顾着种子。一天,他终于破土而出了?我高兴得一磞老高,赶快叫爸爸妈妈来看,爸爸妈妈也很开心!一天又一天……一盆黄豆都长出来了,就是没看见绿豆芽。绿豆宝宝是不是还在睡懒觉呢?经过我一天天的照顾,终于长出来了!可能是小鸟和春姑娘和小朋友呼唤醒的?我知道老师让我们写这篇作文是为什么?因为老师想让我们知道养几粒种子都这么难,可是母亲养我们就更难了。我一定要报答母亲。
 

  虽然我的种子长出来了,可还有同学培养的植物比我的更棒。我要更好地照顾好我的小芽。

  植物的英语作文【篇二】

  The book says, "all living things will be breathing." I think: "people and animals breathe is possible, but how plants breath?" In order to confirm the book, I decided to do an experiment.

  I chose six pieces from home "callas" the leaves of this plant. They are very strong, grow verdant. I divided them into two groups to do experiments.

  I was in the first set of above three leaf blade evenly coated with vaseline. Under a second set of three leaf blade evenly coated with vaseline.

  Two days later, I found that the first group and leaves no change, because in the leaves of plants, with many small holes through them, called pores. All kinds of plant leaves, under the skin stomatal more with less, general under the porosity of leaf epidermis more than on the skin. Plants absorb carbon dioxide from the air is through the stomata and oxygen. Use vaseline, after besmear is on blade is closed pores, made from the hole, through the air. Plants used in the manufacture of fuel energy (sunlight) mostly on the leaf, and petroleum jelly coating can not block the sun. In addition, the water from the roots by stem, nor affected by petroleum jelly, so foliar blade will not be affected by any coated with vaseline.

  The second group of leaf blight. Because the blade is applied with vaseline, on the underside of the leaves, plant growth and most of the porosity and average sunlight is less than the back, neither from pores into the air, but not from stomatal out, so the blade will soon wither.

  By doing this experiment, I know that the plant is mainly with the blade on the back of the breath, cannot breathe in the blade is applied in plants. I know how should protect plants.

  书上说:“凡是有生命力的东西都要呼吸。”我想:“人和动物呼吸是有可能的,可植物怎样呼吸呢?”为了证实书上的话,我决定做个实验。

  我从家里选择了六片“马蹄莲”这种植物的叶子。它们都是十分健壮,长得绿茵茵的。我把它们分成两组来做实验。

  我在第一组的三片叶子的叶片上面均匀地涂上了凡士林。在第二组的.三片叶子的叶片下面均匀地涂上了凡士林。

  两天后,我发现:第一组和叶片没有什么变化,因为在植物的叶片上,生有许多小孔,叫气孔。各种植物的叶片上、下表皮的气孔有多有少,一般叶片上的气孔下表皮比上表皮多。植物就是通过这些气孔吸收空气中的二氧化碳和氧气。用凡士林涂在叶片上后,气孔被封闭了,使空气不能从气孔通过。植物用于制造养料的能源(阳光)大都照在叶面上,而凡士林的涂层不能阻挡阳光。另外,水从根部通过茎部运输上来,也不受凡士林的影响,所以叶面涂有凡士林的叶片不会受任何影响。

  第二组的叶片出现枯萎现象。因为叶片背面涂有凡士林,植物的气孔又大多生长在叶片背面,阳光一般照不到叶片背面,空气既不能从气孔进入,又不能从气孔排出去,所以叶片会很快枯萎。

  通过做这个实验,我知道了植物主要是用叶片背面呼吸,不能在叶片背面涂一些妨碍植物呼吸的东西。我从中知道了应怎样保护植物。
