Worksheet Overview

QUESTION 1 of 10

 As you probably know, plants grow from seeds.  In fact, you may have grown some plants from seeds yourself, like cress seeds.

 

There is a special name for when a young plant starts to grow out of a seed - we call it GERMINATION and we say that the seed is GERMINATING.

Bean seedlings

Here are some beans germinating and some bean seedlings growing.

 

Do you know what seeds need if they are to grow well?  They all need THREE things:

 

WATER      WARMTH      AIR

 

Then do you know what conditions do we need to provide if we want to produce strong, healthy plants?

 

This worksheet will help you to find out more about sowing and growing seeds.  Let's get going (or should that be growing?)!

Which word means what happens when a seed begins to grow into a new plant?

pollination

fertilisation

germination

reproduction

What are the three things a seed needs to germinate?

light, water, soil

light, air, warmth

water, warmth, air

Three bean seeds were planted in separate pots.

 

One pot was kept in the fridge, the second pot was placed on a sunny windowsill and the third pot was kept under a bucket in a warm place.  All of the seeds were kept watered.

 

Which seeds grew first?  Choose ONE answer.

the seed in the fridge

the seed under the bucket

the seed on the windowsill

the seeds in the fridge and under the bucket grew first

the seeds under the bucket and on the windowsill grew first

Why do new plants grow in the spring?

seeds germinate when the weather gets warmer

seeds germinate when the days get longer

seeds germinate when people dig their gardens

What is the first thing to appear when a seed begins to germinate?

a stem

leaves

a root

A group of children plant three trays of cress seeds.

 

One tray is watered regularly and kept moist. The second tray is given lots of water and kept wet. The third tray isn't watered at all. All of the seed trays are kept warm.

 

Which tray do you think grows best?

the tray without water

the moist tray

the very wet tray

all the trays grow equally well

  • Question 1

Which word means what happens when a seed begins to grow into a new plant?

CORRECT ANSWER
germination
EDDIE SAYS
If you remember back to the introduction we saw that GERMINATION is when a seed sprouts and a new plant (or seedling) begins to grow from it. It's easy to do with beans and you can see the fluffy root popping out first, and then the shoot with tiny leaves on. It's very exciting!
  • Question 2

What are the three things a seed needs to germinate?

CORRECT ANSWER
water, warmth, air
EDDIE SAYS
So, water, warmth and air. Why? Well, the water softens the tough coat around the seed, so that the root can break it open. It also helps to start moving the food stored in the seed down to the root, to give it the energy to start growing. Warmth speeds it all up and air is important so that the seedling can get the energy it needs for growing out of the food store. If you've never tried growing seeds, it's dead easy - just get a packet of cress seeds and some kitchen towel. Put the kitchen towel on to a plate, make it damp, sprinkle a few seeds on and check on them every day for a week, keeping the kitchen towel moist. Watch what happens!
  • Question 3

Three bean seeds were planted in separate pots.

 

One pot was kept in the fridge, the second pot was placed on a sunny windowsill and the third pot was kept under a bucket in a warm place.  All of the seeds were kept watered.

 

Which seeds grew first?  Choose ONE answer.

CORRECT ANSWER
the seeds under the bucket and on the windowsill grew first
EDDIE SAYS
The seeds that were kept warm and watered grew first, even though one was kept in the dark. This tells us that light is not important for germination, but water and temperature are important. If you think about it, that makes sense. Where are most seeds when they germinate - under the soil! It's dark there, so light doesn't matter until the seedling has leaves. When do many germinate? Springtime - that's when the weather is warming up. Ah, now it all starts to make sense!
  • Question 4

Why do new plants grow in the spring?

CORRECT ANSWER
seeds germinate when the weather gets warmer
EDDIE SAYS
Seeds need warmth to germinate. Many plant seeds stay dormant (inactive) in the soil over winter. When the weather starts to warm up in the Spring, and the soil is moist, the conditions are right for the seeds to germinate.
  • Question 5

What is the first thing to appear when a seed begins to germinate?

CORRECT ANSWER
a root
EDDIE SAYS
The first thing to emerge from a seed is a root. This is important because no water is stored in the seed. The root pushes into the soil and starts to draw up the water the growing seedling needs. Not only that but the root provides a brilliant 'anchorage' for the plant - it supports it in the soil so that it's anchored firmly and can start to grow without being blown over by a breeze!
  • Question 6

A group of children plant three trays of cress seeds.

 

One tray is watered regularly and kept moist. The second tray is given lots of water and kept wet. The third tray isn't watered at all. All of the seed trays are kept warm.

 

Which tray do you think grows best?

CORRECT ANSWER
the moist tray
EDDIE SAYS
Seeds need water to grow, but not too much. Too much water stops the seeds getting the air that they also need to grow, rather like they've been drowned. Without water it's just like they're still in the packet - nothing! They just need the right amount - not too much, not too little.
