4. One of the cells pictured below is a human brain cell. The other cell is found in human blood. Which cell came from the brain? Explain your answer.

Question

[Figure 9]

Answer 1

I'm unable to see Figure 9, but I can help you differentiate between a human brain cell (neuron or glial cell) and a typical blood cell (such as a red blood cell or white blood cell) based on characteristics you might observe.

1. Neurons: If the brain cell is a neuron, it will likely have a distinct structure with a cell body (soma) that includes a nucleus, long extensions such as dendrites and one longer axon, which are important for transmitting signals.

2. Glial cells: These are support cells in the brain. They can vary in shape but generally lack the long axons characteristic of neurons. Instead, they might be more versatile in shape and larger than other cells.

3. Blood Cells: If you are looking at blood cells, red blood cells are typically oval or disk-shaped and lack a nucleus. White blood cells (like lymphocytes or neutrophils), on the other hand, usually have a nucleus and a more irregular shape, but they are generally smaller compared to brain cells.

To determine which cell is from the brain, look for features such as the presence of an axon or dendrites in the case of neurons, or the overall larger size and complex structure typical of brain cells as compared to the simpler shapes of red or white blood cells.
