     Plants are very important living things. Life could not go on if there were no plants. This is because plants
can make food from air, water and sunlight. Animals and man cannot make food from air, water and sunlight.
Animals get their food by eating plants and other animals. Therefore animals and man need plants in order to
live. This is why we find that there are so many plants around us. If you look carefully at the plants around
you, you will find that there are two kinds of plants: flowering plants and non-flowering plants. Flowering
plants can make seeds. The seeds are protected by the fruits. Some fruits have one seed, some have two,
three or four, and some have many seeds. But a few fruits have no seeds at all. An example of a fruit without
seeds is the banana fruit. Most non-flowering plants do not grow from seeds. They grow from spores (胚芽).
Spores are very small. Some spores are so small and light that they can float in the air. We may say that spores
are quite the same as seeds. When these spores are all on wet and shady places, they usually grow into new
plants.

　　As if there weren’t enough of them in the world already, scientists have succeeded in cloning flies．The alike fruit flies are the first insects ever cloned, says the Canadian team that created them．The question everyone asks is why anyone would want to clone flies in the first place．She hopes that the insects, which are very easy to experiment with, will help to adjust the cloning process in other animals and even in humans, where the technique is being researched to aid production of therapeutic(治療的)stem cells．

　　In cloning, the DNA-containing nucleus of an adult cell is injected into an egg whose own nucleus(細(xì)胞核)has been removed．At the moment, the majority of cloned mice, sheep and other animals die before birth．It is thought this is because the adult DNA is not properly ‘reprogrammed’．

　　Using flies, researchers might discover genes that are important for this reprogramming, and that have matches in other animals．That is because it is relatively easy in flies to knock out the function of a single gene and then attempt cloning with these cells, which will test whether that gene is important．If such genes are confirmed, then in theory cloned mammalian embryos(晶胚)might be grown in selected solutions that change the activity of those genes to improve the technique’s success rate．Although some groups have attempted to clone insects before, Lloyd says this is the first time it has been successful．The team used a slight difference on the standard cloning process：they transferred nuclei taken from embryos rather than fully-grown adult cells．They sucked several nuclei(pl)out of developing fly embryos, and injected them into a fertilized(已受精的)fly egg．From over 800 early attempts, they cloned five adult insects, the group reports in the journal Genetics．

[　　]

A．

the difference of other animals’ genes

B．

the improper technique of clone

C．

the complex of other animals

D．

(4)
