Worksheet Overview

QUESTION 1 of 10

A plant is a living thing. Like other living things, it is made up of different parts, each with a job to do to keep the plant alive and healthy.

 

Three of the most important parts of a plant are its ROOTS, STEM and LEAVES. All three need to be healthy if a plant is to grow well.

 

In this worksheet you're going to be looking at the different roles played by the roots, stem and leaves - that is, what they do for the plant.  Imagine you didn't have any legs - what would happen?  That's just ONE of the things your legs do for you!

 

Growing plant

 

Which part of a plant is usually hidden under the ground?

Roots

Flowers

Stem

Leaves

What do the roots do?

Make food for the plant

Anchor the plant in the ground

Get water and nutrients from the soil

What part of the plant do the leaves grow from?

Roots

Flowers

Stem

What does the stem do?

It provides support for the leaves and flowers.

It carries water and nutrients from the roots to the leaves

It carries food from the leaves to the roots

Which is healthier?

A plant that has lots of leaves

A plant that has lost its leaves

What do the leaves do?

They keep the stem cool

They keep the plant upright

They make food for the plant

In many plants, the roots spread out a very long way under the ground.

To help in competing with nearby plants for space

To help 'draw up' more water

To help the plant spread to new areas

One important job of the stem is in helping to carry water up the plant from the roots

How do you think the water travels inside the stem (don't worry if you don't actually 'know' - have a think about the choices below and pick the one you think is most sensible - it's all about learning!)

The water travels in tubes

The water soaks up the stem, rather like a sponge

There is a special plant pump in the roots which pushes the water up the stem

Leaves come in all sorts of shapes and sizes. However, many plants have leaves that are quite broad in shape (that's rather wide, instead of narrow).

To help the plant stay balanced

To help support the plant when it's windy

To help the plant get more sunlight energy

Many plants have leaves with 'ribs' along the width and length.

 

Leaf

 

What do you think these might do to help the plant?

One of these four choices is incorrect - can you find it?

Helps the leaf to keep its shape

Supports the leaf

Transports substances around the leaf

Helps with taking in air

  • Question 1

Which part of a plant is usually hidden under the ground?

CORRECT ANSWER
Roots
EDDIE SAYS
The roots grow in the ground - guess you knew that! Why? Well, that's coming up.
  • Question 2

What do the roots do?

CORRECT ANSWER
Anchor the plant in the ground
Get water and nutrients from the soil
EDDIE SAYS
The two main jobs of the roots are to keep the plant anchored in the ground (rooted) and to get water and nutrients for the plant from the soil. The roots often spread out wide to help with both jobs.
  • Question 3

What part of the plant do the leaves grow from?

CORRECT ANSWER
Stem
EDDIE SAYS
The leaves of a plant grow out from the stem, sometimes two or four on either side, sometimes alternately, sometimes in a bunch at the top - there's lots of ways.
  • Question 4

What does the stem do?

CORRECT ANSWER
It provides support for the leaves and flowers.
It carries water and nutrients from the roots to the leaves
It carries food from the leaves to the roots
EDDIE SAYS
Well, amazingly, the stem does all of these things! As you can see it's a very important part of the plant, helping to carry goodies all around the plant and helping to support the vital food factories of the leaves - no leaves, no plant (in most cases!).
  • Question 5

Which is healthier?

CORRECT ANSWER
A plant that has lots of leaves
EDDIE SAYS
Guess that was easy! A healthy plant will have lots of leaves to make food for it, so for most plants to lose their leaves is a disaster (say after a hurricane has struck) and they'll have to use their reserves of stored food to manufacture new leaves ... or die.
  • Question 6

What do the leaves do?

CORRECT ANSWER
They make food for the plant
EDDIE SAYS
Amazingly, a plant's leaves are its food factories. As you'll learn, there is an incredible process that takes place in the leaves that actually MAKES food (seemingly out of nothing!) and sunlight is a vital ingredient in this process. The leaves spread out to 'capture' sunlight energy to use in making their food.
  • Question 7

In many plants, the roots spread out a very long way under the ground.

CORRECT ANSWER
To help 'draw up' more water
EDDIE SAYS
The need to gain as much water as the plant needs at all times is terribly important - water helps the plant to stay upright, to transport materials all over the plant and lots of other things. In fact some special plants do use their roots to compete ('fight against') other plants and also to help them spread to new areas, but getting water is the big one.
  • Question 8

One important job of the stem is in helping to carry water up the plant from the roots

How do you think the water travels inside the stem (don't worry if you don't actually 'know' - have a think about the choices below and pick the one you think is most sensible - it's all about learning!)

CORRECT ANSWER
The water travels in tubes
EDDIE SAYS
Any of those choices might seem possible, but the correct answer is that that stem contains loads of tiny tubes, like pipes, which carry the water up the stem and into the leaves. Amazingly it all works against gravity without any need for a pump. Wonderful!
  • Question 9

Leaves come in all sorts of shapes and sizes. However, many plants have leaves that are quite broad in shape (that's rather wide, instead of narrow).

CORRECT ANSWER
To help the plant get more sunlight energy
EDDIE SAYS
The shape of a leaf really helps with the 'gathering' of sunshine - ever seen a lizard "basking" in the sun - it turns its side to the sun so that as much of its body surface is facing the sun as possible. If leaves were like needles (which many conifers are) then each one only collects a little sunshine. Broader leaves collect much more per leaf.
  • Question 10

Many plants have leaves with 'ribs' along the width and length.

 

Leaf

 

What do you think these might do to help the plant?

One of these four choices is incorrect - can you find it?

CORRECT ANSWER
Helps with taking in air
EDDIE SAYS
In fact the ribs help with so many things, like keeping the leaf spread out to 'capture' sunlight, containing tubes to carry substances, things like that. However, they don't help with taking in air - that's one of the jobs of the main part of the leaf.
