Worked Solution & Example Answer:Figure 8 shows a method of producing plants - Edexcel - GCSE Biology - Question 4 - 2018 - Paper 1
Step 1
Some cells in each plantlet develop into root cells. Name the process occurring as these cells develop into root cells.
Answer
The process occurring as these cells develop into root cells is called differentiation. This is when unspecialized cells develop into specialized cells with specific functions.
Step 2
Describe the advantages of producing plants by the method shown in Figure 8.
Answer
Producing plants through this method has several advantages:
- Increased Yield: Many plants can be produced from a single parent plant, leading to higher yields.
- Faster Growth: The method is generally quicker than traditional sexual reproduction.
- Genetic Uniformity: The resulting plants are genetically identical (clones), ensuring consistency in traits.
- Desired Characteristics: It allows for the cultivation of plants with specific desirable characteristics, including rare or endangered species.
- Difficult-to-Grow Species: This method can be used to obtain plants that are difficult to grow from seeds.
