The correct Answer is:
To solve the question regarding the star-shaped mass of crystals of calcium oxalate found in the cells of Chenopodium and Colocasia, we can follow these steps: ### Step-by-Step Solution: 1. **Identify the Type of Crystals**: The question specifies that we are looking for a star-shaped mass of crystals made of calcium oxalate. 2. **Understand the Context**: Calcium oxalate crystals can take various forms in plant cells, and they are commonly found in certain plants, including Chenopodium and Colocasia. 3. **Explore the Options**: The options provided in the video transcript include: - Crystal sand - Spherophyll - Druse - Both B and C 4. **Define the Terms**: - **Druse**: A type of crystal aggregate, often found in plant cells, made of calcium oxalate. - **Spherophyll**: Specifically refers to star-shaped crystals of calcium oxalate. 5. **Determine the Correct Answer**: Since the question specifies "star-shaped mass of crystals," the term that directly corresponds to this description is **spherophyll**. However, since druse is also mentioned and is a broader category that includes calcium oxalate crystals, both B (spherophyll) and C (druse) can be considered correct. 6. **Final Conclusion**: The answer to the question is that the star-shaped mass of crystals of calcium oxalate found in the cells of Chenopodium and Colocasia is called **spherophyll**, and both B and C (spherophyll and druse) are correct. ### Final Answer: The star-shaped mass of crystals of calcium oxalate found in the cells of Chenopodium and Colocasia is called **spherophyll** (and druse).

The regular three dimensional arrangement of points in a crystal is known as crystal lattice and the smallest repeating pattern in the lattice is called unit cell. The unit cells are characterised by the edge lengths a, b, c and the angles between them alpha, beta and gamma respectively. Based on this, there are seven crystal systems. In a cubic unit cell: a=b=c and alpha = beta=gamma=90^(@) The number of points in simple, body centred and face centred cubic cells are 1,2 and 4 respectively In both the hcp and ccp of spheres, the number of tetrahedral voids per sphere is two while the octahedral voids is one.
