Lesson Starter 1. What is the meaning of a true breeding organism? 2. A male mouse which is homozygous dominant for a black coat (BB) is crossed with a female mouse which is homozygous recessive for a white coat (bb)- what will the GENOTYPE and PHENOTYPE be of the f1 offspring? 3. Two members of the F1 offspring are then
crossed- what will the possible gene combinations be of the F2 offspring? 4. What does the term HETROZYGOUS mean? Growth and Development Learning Intention To learn about growth and
development in plants How do plants grow? http://www.bbc.co.uk/education/clips/zpgb4wx Germination What is germination? The process where a plant
grows from a seed What 3 factors affect germination? http://www.bbc.co.uk/education/clips/z4htsbk What 3 factors affect germination?
Water Oxygen Warmth Temperature and germination Plants grow best at their OPTIMUM temperature
What is the optimum temperature? 20C Plant growth: copy Germination is when the seed starts to grow into a plant It requires Water, Oxygen and
Warmth The optimum temperature for germination is 20C Copy graph and describe the trend in seed germination Factors affecting
plant growth Nutrients and Minerals: copy Plants need other elements to grow and develop properly Nitrogen, Phosphorous, Potassium and Magnesium
Task 1 Use the information sheets to complete the table about the nutrients needed by plants Mineral Deficiency Potassium
Phosphorus Nitrogen Magnesium Description of the plant
What is the mineral for? Mineral Deficiency Description of the plant
What is the mineral for? Potassium older leaves display potassium deficiency first Potassium is also needed for protein synthesis, and the
opening and closing of the stomata. Phosphorus poor growth and leaves that turn blue/green (but not yellow).
used for energy transfer, photosynthesis, nutrient movement, and reproduction Nitrogen Leaves are pale green or yellow because they are unable to make sufficient
chlorophyll to make chlorophyll. Magnesium to premature ageing of plant cells.
the production of chlorophyll. Magnesium Magnesium is necessary for the production of chlorophyll. Without the chlorophyll, the plant leaf cannot photosynthesise (make its
own food). Lack of magnesium can lead to premature ageing of plant cells. Older leaves often show magnesium deficiency first, as it is easily transferred from leaf to leaf when it is not bound to chlorophyll. Phosphorus Phosphorus is found in every
living plant cell. It is used for energy transfer, photosynthesis, nutrient movement, and reproduction. Lack of phosphorous means poor growth and leaves that turn blue/green (but not yellow). Oldest leaves are affected first. Fruits are small and acid tasting. The undersides of leaves, and the veins and stems, may turn
purple. Potassium Potassium is needed in the cytoplasm of plant cells so that reactions can occur. Potassium is also needed for protein synthesis, and the opening and closing of the stomata. Potassium is easily moved between cells so older leaves
display potassium deficiency first as it is moved to younger leaves. Nitrogen Plants use nitrogen to make chlorophyll. A lack of chlorophyll means that the plant cant photosynthesise so it
cant make food to grow. Leaves are pale green or yellow because they are unable to make sufficient chlorophyll. Nutrients in soil Nutrients are added to soil when plants
die or leaves fall. When crops are harvested, they are removed from the ground so this does not happen. In this case the soil will not contain the nutrients needed for healthy plants. What can be added to the soil to help plants?
Task 2 Explain which fertiliser you would use and why to: 1) Improve photosynthesis 2) Stop premature aging of plants 3) Improve protein synthesis in plants Fertilisers: copy
Fertilisers can be added to soil to replace the nutrients lost when plants are harvested Different fertilisers contain different ratios of nitrogen, magnesium, phosphorous and potassium- some are better at particular jobs than others Fertilisers: disadvantages Increasing population- more food needed
Too much fertiliser- pollute water supply and cause eutrophication Homework: Find (and write) the meaning of the word EUTROPHICATION What is germination? The process where a plant grows from a seed
What 3 things are required for germination? Water Oxygen Warmth What is meant by
the term optimum temperature The temperature at which the highest percentage of plants germinate What is the optimum temperature for germination
20 degrees celcius Why is it important that plants have space? To reduce competition for water, light, nutrients etc Why do plants need
light For photosynthesis-making food What are the 4 other main elements plants need? Magnesium, Nitrogen, Potassium and phosphorous
What can be added to soil to improve the concentration of the nutrients needed? Fertilisers Predict the height of
