GROUP 7

--------------------------------------------------------------------1.How did the seed get in to the crack on the

wall?(slide 2 & 3)2.How did the seed grow well in the crack?(slide 4

& 5)

wind* Some fruits are adapted to “catch

the wind” and become blown away. The wind will bring the fruit with seeds/a seed to a new destination to grow. Examples include dandelions and sycamores.

* Facts from: http://www2.bgfl.org/bgfl2/custom/resources_ftp/client_ftp/ks2/science/plants_pt2/wind.htm

bursting* Some fruits burst open, sending

seeds flying in all directions. The seeds are then dispersed and ready to grow if it lands on ground with warmth, air and moisture. Examples include peas and gorse.

shakers* Poppy seed heads, when dried by the

sun, have little holes all around their top (like a pepper shaker). These shake when it’s windy and scatters seeds everywhere to grow by the holes.

* Facts from: http://www2.bgfl.org/bgfl2/custom/resources_ftp/client_ftp/ks2/science/plants_pt2/shakers.htm

water* Some fruits are waterproof and can

float. A good example is the coconut. It grows near water and when its fruit ripens, the fruit drops into the water. The fruit then floats along the current and waits to be washed ashore to grow.

* Facts from: http://www2.bgfl.org/bgfl2/custom/resources_ftp/client_ftp/ks2/science/plants_pt2/water2.htm

catching a lift* Some fruits have tiny

little hooks on them and can cling on to an animal’s fur or wool to be carried off to disperse the seeds.

There might have been some dirt, warmth, air and moisture in the crack. This place will help the seed grow as the conditions are met.

Plants grow from seeds - which are often very small, in many cases. As they blow through the air and tumble along the ground, seeds will often get "caught" in something - a crack, for example. If there is any dirt in the crack (there usually is) and any moisture (the crack holds moisture) the seed will germinate and grow.

Sometimes, people plant plants in cracks to decorate their pavement too. So there may be others who are taking care of the plant in the crack.

 

HOPE YOU HAVE BEEN LOOKING OUT FOR THE SMILEY FACES AND LISTENING ATTENTIVELY TO THE SPEAKER. Name five ways of seed dispersal mentioned in our slides?

ANS: wind, water, bursting, shakers, catching a lift.

Name the conditions needed for the seed to grow well in the crack? ANS: dirt, water, warmth and air.

What is the name of this plant?

ANS: tembusu tree.
