Loss of pollinators lead to crop destruction - third year of famine What is the message that is brought across by the title and article?
The loss of the wild bees, butterflies and moths has caused major food shortages because they usually help pollinate the food crops; the message might also be a warning to us to value our bee and butterfly populations more, and to reduce air pollution. Explain what the link is between the loss of pollinators and crop failures.
The pollinators are not around to pollinate the flowers of the crop plants. Therefore, the flowers are not fertilised and can then not produce seeds. There are then no seeds to plant the next crops for the next year, and therefore there is less food for humans.
Which specific pollinators were lost? Wild bees, butterflies and moths. What reason did the article provide for the loss of these pollinators? The air pollution and resulting acid rain damaged the wings of the pollinators, who could not fly to reach nectar and therefore died of starvation.
Explain at least two ways in which wind pollinated plants' structures are adapted for wind pollination. Anthers are carried on long filaments that hang down. This allows the wind to move and carry away the pollen easily.
Pollen grains are light and dry to prevent them clumping together and are easily carried on the wind. Female stigma is feathery and branched and acts as a filter trapping the pollen that is blown through it.
How do you think the researchers could modify the crops' flowers so that they are able to be pollinated more efficiently by wind? Learners should make reference to the above adaptations in plants which are already adapted to be pollinated with the help of the wind. Do you think the situation described in this article could happen in the future?
Write a paragraph where you explain your reason why. Learners can either agree or disagree that this could happen in the future. Their reasoning is important in this question. For example, they could reason that it might happen as there is already lots of air pollution and it is not decreasing so it could get to a level where it affects pollinators.
Or else, they could say that they do not think air pollution will get to the level where it affects the flight of pollinators, or there could be other pollinators that might not be affected, etc.
What happens after the pollen lands on the stigma of the flower? Do you remember that the pollen grains contain the male sex cells, and the ovary contains the ovules or female sex cells. The male and female sex cells each contains only half of the genetic material DNA from the parent plant.
After pollination, the male sex cell in the pollen grain needs to fuse with a female sex cell in the ovary to produce a fertile seed. This is called fertilisation. In angiosperms, each pollen grain contains two male sex cells. See if you can identify the reason for this as you read through the steps for fertilisation.
The process of fertilisation in plants occurs in clearly defined steps: After the pollen grain lands on the mature stigma of a flower from the same species, the pollen produces a tube. This pollen tube starts to grow from the stigma and down the style. This transports the male sex cells to the ovules.
The pollen tube growing down the style to the ovary. There is a small structure inside the ovule called the embryo sac. When the pollen tube bursts into the ovule, one of the male sex cells fertilises the female sex cell in the embryo sac.
This fertilised egg develops into a seed. The other male sex cell joins with another cell in the embryo sac to form the endosperm. The endosperm is the starchy food that is stored in the seed once it has ripened. Later this food is used to feed the germinating seed until it has formed leaves and can produce its own food through photosynthesis.L/O To be introduced to the features of a newspaper recount Features of a newspaper article Headline Orientation Main body of text Photo Caption Reorientation Headline In bold Catchy Alliteration Interests the reader Serious or humorous Only has a few words Action verbs Orientation This introduces the story and should GRAB our attention.
Reading has been high on the list of priorities for many schools since the new National Curriculum ; if reading wasn't on your school’s radar in with the increased curriculum standards, it certainly was after the KS2 SATs reading paper in Newspaper report – The Diamond Theft Poster 1 is presented as a newspaper report about the theft of a diamond.
It displays typical newspaper features and illustrates the report style of writing. The same news story is also presented as a television news broadcast in On-screen resource 1 Teachers’ notes by Mim Barnes — Literacy .
Students learn the journalistic skill of writing a press release. Learning aims. By the end of the lesson, students should understand: Students write a press release.
Ask students: How do journalists find out about news? Distribute copies of this worksheet containing a press release and newspaper article about a Newsround school visit. Excellent resource, will use it for a pre writing session to explain what a good news paper report needs to have and thus will highlight the success criteria.
