What does a healthy plant need to grow?
Water & Air |
Plants take water from the soil, carbon dioxide from the air |
Light |
They use chlorophyll to absorb light energy from the Sun to convert water and carbon dioxide into food. The food is called glucose which is a sugar and store of energy |
Warmth |
Warmth is essential for growth |
Space to Grow |
Plants need space to grow to avoid overcrowding & competition for water, light and mineral salts |
Nutrients |
Nutrients are found in the soil and are absorbed through plant roots to keep the plant healthy & green |
What is an unhealthy plant?
No water = leaves wilt |
No light = plants become tall, weak & yellow |
No warmth = plants do not grow and are damaged |
Too much warmth = dry & shrivelled leaves |

What is the function of the leaf?
• Makes food through a process called photosynthesis
• Leaves contain cell structures called chloroplasts which contain chlorophyll (a green pigment). Chlorophyll absorbs light energy from the Sun
• Leaves are wide so they have more area to absorb light
• Leaves are flat so they can capture water |
What is the function of a stem?
• Transports water and nutrients to rest of plant
• Holds leaves upright and leans leaves towards the Sun |
What is the function of the fruit?
• Produced from flowers and the seeds of it will grow into new plants |
What is the function of a flower?
• Makes seeds for reproduction
• Pollination is when insects carry pollen from the stamen of one plant to the carpel of another
• Flowers are coloured and scented to attract pollinators |
What is the function of the root?
• Anchors the plant in the soil so it doesn’t blow away
• Absorbs water and nutrients and transports to rest of plant |

Draw the parts of a Flower
List Female Parts of Flower & Function
Part |
Function |
Petal |
Brightly coloured and scented to attract pollinators that will transfer pollen from anther of one plant to the stigma of another for pollination to occur |
Carpel |
Carpel is the female part of the flower containing the stigma, style and ovary |
Stigma |
At the top of the carpel and is sticky to receive pollen from other flowers |
Style |
At the base of the stigma and supports stigma |
Ovary |
At the bottom of the carpel and contains ovules (female sex cells) |
List Male Parts of the Flower & Function
Stamen |
The male part of the flower |
Anther |
At the top of the stamen and produces pollen (male sex cells) |
Filament |
At the bottom of the stamen and supports the anther |
What is the function of the sepal?
A thick protective layer that protects the flower bud until it opens then provides support |
