Worksheet Overview

QUESTION 1 of 10

Our Earth is populated by millions of different types of plants and animals, most of which are made up of a variety of structures called organs. These organs carry out a range of different functions to ensure that the organism operates correctly.

Here are some of the organs from the human body:

 

 

In this worksheet we're going to have a look at those different structures, both plant and animal, and examine their role within the organism itself.

Both plants and animals contain a variety of organs which have important jobs to do.

 

Below is a list of organs and all you have to do is to decide which are PLANT organs and which are ANIMAL organs by dragging the correct label next to the organ.

Column A

Column B

Roots
Animal
Brain

Lungs

Kidney

The next few questions describe the function (job) of a particular organ. Pick the organ from the list that you think carries out this function.

 

What pumps blood around the body?

leaves

heart

liver

stem

Which organ uses sunshine to make food?

leaves

brain

flower

kidneys

Which organ draws water and minerals from the ground?

kidneys

intestines

roots

stem

Which organ co-ordinates all the functions of the body?

leaves

brain

flower

heart

Which one of these organs is NOT directly involved in the digestion of food?

intestines

liver

brain

stomach

Which one of these organs is NOT directly involved in transporting substances around the plant?

roots

stem

flower

leaves

Organs in plants and animals are made up of groups of similar cells - what are these groups called?

layers

tissues

regions

The eye is an organ found in humans. Which ONE of the following groups of similar cells (from Q8) are NOT found in the eye.

blood

nerves

light-sensitive cells

bone

muscle

See whether you can work out which plant organ contains the following parts: 

 

  • nectary
  • petals
  • sepals
  • anthers
  • pollen
leaves

flower

roots

stem

  • Question 1

Both plants and animals contain a variety of organs which have important jobs to do.

 

Below is a list of organs and all you have to do is to decide which are PLANT organs and which are ANIMAL organs by dragging the correct label next to the organ.

CORRECT ANSWER

Lungs

Stem

Liver
Animal
EDDIE SAYS
OK, so not too difficult to start you off: Roots-Stem-Leaf-Flower for plants and Brain-Lungs-Kidney-Liver for animal - mind you, only 'higher' animals have organs like lungs - insects don't, although they're animals.
  • Question 2

The next few questions describe the function (job) of a particular organ. Pick the organ from the list that you think carries out this function.

 

What pumps blood around the body?

CORRECT ANSWER
heart
EDDIE SAYS
The heart is the organ concerned with pumping blood. In mammals it contracts regularly (pumps) to force the blood through blood vessels, collecting oxygen and delivering different substances all over the body.
  • Question 3

Which organ uses sunshine to make food?

CORRECT ANSWER
leaves
EDDIE SAYS
Only plants can use sunshine to make food, so that takes out brain and kidneys which are animal organs. The leaves contain cells which can convert light energy into food energy - just as well, as you depend on that all day, every day!
  • Question 4

Which organ draws water and minerals from the ground?

CORRECT ANSWER
roots
EDDIE SAYS
If it\'s in the ground, it must be a plant; the roots are designed not only to anchor the plant firmly in the soil but also to draw up the water and minerals the plant needs to function correctly.
  • Question 5

Which organ co-ordinates all the functions of the body?

CORRECT ANSWER
brain
EDDIE SAYS
The human brain is the most advanced organ on the planet, capable of amazing speeds of calculation that enable us to live very complex lives. Thank heavens we don\'t have to concentrate on running all the different organs of the body - the brain just gets on with it all!
  • Question 6

Which one of these organs is NOT directly involved in the digestion of food?

CORRECT ANSWER
brain
EDDIE SAYS
The brain may keep an \'eye\' on what\'s going on with our digestion but unlike the other three is does not become directly involved with it. The liver produces some of the chemicals that are used in digestion and also deals with a number of the substances produced as a result of digestion.
  • Question 7

Which one of these organs is NOT directly involved in transporting substances around the plant?

CORRECT ANSWER
flower
EDDIE SAYS
The flower is designed to attract insects (unless wind-pollinated) for pollination. However, the roots and leaves produce substances that are fed into the transport system of the plant and carried to and fro along the stem/stalk/trunk.
  • Question 8

Organs in plants and animals are made up of groups of similar cells - what are these groups called?

CORRECT ANSWER
tissues
EDDIE SAYS
Whilst organs are really important in carrying out certain functions, they themselves are made up of TISSUES, which are groups of the same sort of cell. Take skin, for example: there's dermal tissue, epithelial tissue, subcutaneous tissue - oh, lots!
  • Question 9

The eye is an organ found in humans. Which ONE of the following groups of similar cells (from Q8) are NOT found in the eye.

CORRECT ANSWER
bone
EDDIE SAYS
Eyes have loads of different tissues in them: light-sensitive ones for picking up light, nerves for relaying that information to the brain, muscle for moving the eye and so on, but.... they don\'t contain any bone tissue.
  • Question 10

See whether you can work out which plant organ contains the following parts: 

 

  • nectary
  • petals
  • sepals
  • anthers
  • pollen
CORRECT ANSWER
flower
EDDIE SAYS
The flower of an insect-pollinated plant has colourful petals to attract insects to the nectar (made in the nectary) and so carry away the pollen made in the anthers.
