Photosynthesis and Oxygen
Photosynthesis is a chemical
reaction that takes place
inside a plant, producing
food for the plant to survive.
Carbon dioxide, water and
light are all needed for
photosynthesis to take
place.
Photosynthesis happens in
the leaves of a plant.
Oxygen Producers:
25% - Micro Algae: The primary source of oxygen for a pond is from
microscopic algae (phytoplankton) or submerged plants. In the
presence of sunlight, these produce oxygen through
photosynthesis and release this oxygen into the pond water.
25% - Land Plants: Such as trees, leafy greens, shrubs and smaller
plant life that covers the earth’s surface.
50% - Marine Microbes: Marine microbes are tiny, single-celled
organisms that live in the ocean. This process is very similar to that
of micro-algae but instead cyanobacteria (see picture) turn carbon
dioxide into oxygen.
Does air quality matter?
Air pollution can cause both short term and long term effects on health and many people are concerned
about pollution in the air that they breathe.
Can you think of 3 things that are causing or contributing to poor air quality or air pollution across the
world?

Know about seeds
Word Bank: Flower, Seedling, leaves, seed pod, water, seed, seed coat, shoot, roots, food
store, sun.
Match the words with the statements below:
1. These are usually colourful. Bees go into these and cause pollination.
2. This is needed to help feed the plant, without it the plant would dry up and die.
3. When a plant begins to grow, but it still small, with maybe only 2 – 4 established
leaves it is known as a?
4. These act like solar panels, taking in the sun’s rays and converting the light into
energy.
5. This is what we plant in the soil, which grows into a plant.
6. Before a seed is planted, it usually has a hard shell or some kind of shell to protect it,
this is known as?
7. When a seed begins to grow, it pushed its way through soil to be above ground, this
early stage of the plant is called the?
8. This helps the plant grow, it is essential for photosynthesis – this is the process where
water, BLANK and carbon dioxide are converted into food to help a plant survive.
9. When a seed begins to grow, and the shoot is established and some roots have
formed, the original seed acts as a BLANK to help the plant survive and grow.
10. Underground plants have BLANK and they give the plant water and nutrients from
soil.
11. When a flower has ‘flowered’ for the year it begins to die off, but before it does it
will create BLANK to help the flower re-seed the following year. These can also be
collected and stored.
‘Germination is the process by which a plant
grows from a seed’

Indoor Sowing Techniques
‘If you ask the average person on the street how to grow a plant in a
container, they will undoubtedly tell you to put some soil in a bucket
or pot and then pop in the plant, water it regularly, throw in some
fertiliser occasionally and Bob’s your uncle…….!’
But it’s not really that simple….. Plants and crop need the right set of nutrients
and the correct ratios of fertiliser to grow successfully. This is why you should
choose what you are going to plant first before sourcing the appropriate
growing mediums.
Important things to consider:
Where to grow the plant?
How to grow the plant?
What to grow them in?

What is ‘Damping off?’
Research what ‘damping off’ means and identify some of the
causes for it.
How can we try to prevent damping off occurring?
4.1 & 4.3 ‘Hardening off’ and ‘planting out’ skills
Think of reasons why we have to harden off plants gradually and why
specific requirements for planting outdoors are needed to enable successful
growing techniques.
What do I know about
specific growing
techniques?

What is compost?
What can we put into the compost bin?
Compost is organic matter that has been decomposed in a process called composting. This
process recycles various organic materials otherwise regarded as waste products and produces
a soil conditioner. Compost is rich in nutrients.
Compost can then be used in the garden to improve soil quality, add nutrition to raised beds
and create new growing spaces.
Can you label the
composting process?

Fully composted
organic material
Food and garden
waste (Organic
Material)
Compost Bin
Partly decomposed
organic material

Weeding
Weeding is an important control method practiced in many crops. The removal of weeds
is useful because these unwanted plants compete with the crop for space, water and
nutrients. Water can infiltrate more rapidly and roots of the cultivated plants can develop
in a better way.
Common Weeds, can you find any around the farm?:
Ragwart at the farm!
Ragwort is mildly poisonous, but the taste of the plant is usually off-
putting to livestock. The plant is usually a biennial (living only two
years and flowering in its second year) but damage to the base of
the plant can make the plant behave like a perennial(living
indefinitely), as new rosettes are formed.
When weeding, keep Ragwart separate from your other weeds.
Ragwat does not need to be composted because the seeds will
continue to grow and germinate within the compost causing almost
indefinite issues.

Re-potting indoor plants
1. Why do indoor plants need repotting?
A common reason for repotting is to give the plant a larger growing space.
Houseplants eventually outgrow
their containers, causing the
roots to become crowded and
compacted. Without enough
space for the roots,
the plant often experiences
stunted growth and may die.
The tangled knot of roots can
stress the plant and deprive it of
nutrients, air, and water.
2. Why else may you repot an indoor plant?
Another less common reason to re-pot an indoor plant is because a new
layer of fresh soil can give a plant the nutrients it needs rather than relying on
chemical fertilizers.
3. What if we want to keep a plant in a certain sized pot?
Root- pruning a root bound plant sounds intimidating, but it's an easy
procedure if your plant isn't too big, and it may even save the life of your
plant. It takes some nerve to root-prune a potted plant, but it truly is a
kindness for a plant that has outgrown its pot.
When you are forced to plant a root-
bound plant, make efforts to untangle
the roots with your fingers before
planting it. If you can tease the root-ball
into a loose bundle of hair-like roots
bristling out from the plant, these roots
![Page 11: Gardening & Horticulture€¦ · Gardening & Horticulture . Photosynthesis and Oxygen Photosynthesis is a chemical reaction that takes place inside a plant, producing food for the](https://reader033.fdocuments.net/reader033/viewer/2022060221/5f0777be7e708231d41d2131/html5/thumbnails/11.jpg)
will rather easily find their way into surrounding soil once you plant the
specimen back into its pot. Good practice would include using fresh
compost when repotting this plant.
4. Dividing a plant.
Dividing plants is easy. Simply dig up the entire clump and then
carefully divide the crown and root ball into two or more section, depending
on the size of the clump.

Wildflowers & Pollination.
A wildflower is a flower that grows in the wild, meaning it was not intentionally seeded or planted.
Why are wildflowers important?
1. They also provide critical habitat for pollinators,
beneficial insects and wildlife, which is important for
ecosystem function and pollination.
2. Wildflowers can improve soil health, prevent
erosion, improve water quality, increase crop yields
and enhance forage conditions for livestock.
What is pollination?
For a flower to be pollinated, pollen must be moved
from a stamen to the stigma. When pollen from a
plant's stamen is transferred to a different plant's
stigma, it is called cross-pollination. Cross-
pollination produces stronger plants and fertilizes
flowers leading to seeds being created (that will allow
more flowers to be created) and the production of
fruit (which we can then eat).
What would happen if pollination didn’t happen?
Bees perform a task that is vital to the survival of agriculture: pollination. In fact, one third of our global food supply
is pollinated by bees. Simply put, bees keep plants and crops alive. Without bees, humans wouldn't have very much
to eat.
Discovering pollinators and wild flowers.
Search the farm and note down as many pollinators you find, while on your travels also note down any types of
wildflowers you see.
Pollinator: Insect that is transporting pollen from flower to flower.
Wildflower: Flowers that self-seed and thrive in the wild.

Extension - Making a Grass Head
Resources Needed
Ladies tights, scissors, grass seeds, elastic bands, PVA glue, googly eyes,
disposable cups/mini plant pots, cotton buds, marker pen.
Activity
Making grass heads to take home so that when their hair grows you can style
it by cutting it with scissors. To make a grass head you must follow these
steps:
Cut a foot out of a pair of tights.
Pour grass seeds into the tights and stuff with cotton buds to about the size
of a tennis ball.
Tie the end in a knot and cut off access material.
Pinch a circle in the middle of the ball shape and tie an elastic band
around it to make a nose shape.
Glue on 2 googly eyes and leave to dry.
Write tour name on a cup/plant pot and put your grass head inside it.
Water every morning once you get it home.
Style hair once the grass has grown.
You can even design outfits out of coloured card for your grass heads and
stick them on to the cup/pot.
You
You can have fun watching your grass heads grow
wild then styling them to make funky hair do’s!
