Question

word bank head middle piece tail nucleus containing dna cell membrane egg cell sperm cell

Explanation:

Match each labeled part of the sperm cell to the correct term from the word bank based on sperm cell anatomy:

1. The segment with mitochondria (the coiled structure) is the middle piece, which provides energy for movement.
2. The long, whip-like structure at the end is the tail, used for locomotion.
3. The rounded front portion of the sperm is the head, which contains the genetic material.
4. The inner structure within the head that holds DNA is the nucleus (containing DNA).
5. The outer layer surrounding the entire sperm cell is the cell membrane.

Answer:

• Middle piece (label pointing to the coiled, mitochondria-containing segment)
• Tail (label pointing to the long, whip-like structure)
• Head (label pointing to the rounded front part)
• Nucleus (containing DNA) (label pointing to the inner structure in the head)
• Cell membrane (label pointing to the outer layer of the sperm)
