Instructions ›
You will hear a recording. Type the missing words in each blank.
* Fill in the missing words into the blank fields
The  word  hormone  is  derived  from  a  Greek  verb  that  means  to  excite.  Hormones  are  found  in  all    organisms  and  function  to  coordinate  the  parts  of  the  organism.  A  hormone  is  a  chemical  signal.  It  is    by  one  part  of  the  body  and  is  then  transported  to  other  parts  of  the  body  where  it    responses  in  cells  and  tissues.  The  concept  of  chemical  messengers  and  plants  first  emerged  from  a  series  of    experiments  on  how  plant  stands  respond  to  light.  Think  about  this,  a  houseplant  on  the  windowsill  grows  toward  light.  If  you  rotate  the  plant,  it  will  soon    its  growth  until  its  leaves  again  face  the  window,  the  growth  of  a  plant  toward  light  is  called  photo  .  In  a  forest  or  other  natural  ecosystem  where  plants  may  be  crowded.

Correct answer: multicellular

Explanation: Listen for "found in all multicellular organisms". It comes before "organisms", so you need a word for a thing with many cells.

Meaning: "multicellular" means made of many cells.

Wrong options:

  • multicelluar: It leaves out the "l". Write "multicellular". Only the exact spelling gets the mark.
  • multicellulars: "multicellulars" has an extra "s" at the end. The speaker says "multicellular", with no "s".
Correct answer: produced

Explanation: On the recording you hear "It is produced by one part". It comes after "is", so the word ends in ed.

Meaning: "produced" means made or created by part of the body.

Wrong options:

  • prodused: It has "s" where the word has "c". Write "produced". Only the exact spelling gets the mark.
  • producing: "producing" is a close word, but it ends in "ing". The speaker says "produced", which ends in "ed".
Correct answer: triggers

Explanation: Listen again to "where it triggers responses". After "it" you need an action word that ends in s.

Meaning: "triggers" means makes responses happen in cells and tissues.

Wrong options:

  • trigers: It leaves out the "g". Write "triggers". Only the exact spelling gets the mark.
  • triggered: "triggered" is a close word, but it ends in "ed". The speaker says "triggers", which ends in "s".
Correct answer: classic

Explanation: Here you hear "series of classic experiments". It comes before "experiments", so you need a word meaning well known.

Meaning: "classic" means well known and important example.

Wrong options:

  • classical: "classical" has an extra "al" at the end. The speaker says "classic".
Correct answer: reorient

Explanation: The speaker says "it will soon reorient its growth". It needs an action word that starts with re, showing a change of direction.

Meaning: "reorient" means change the direction of growth.

Correct answer: tropism

Explanation: You hear "called photo tropism". The missing word is a scientific word that ends in ism.

Meaning: "tropism" means movement or growth toward light.

Wrong options:

  • tropisim: It adds an extra "i". Check the letters: "tropism". A small spelling mistake loses the mark.
  • phototropism: The sentence already has "photo", so do not add it again.
