Study Notes

Sperm Cells

  • Specialized for reproduction, facilitating the transfer of male DNA to the female egg.
  • Features a long tail and streamlined head for efficient swimming towards the egg.
  • Contains a high number of mitochondria to provide energy necessary for movement.

Nerve Cells

  • Adapted to be long, allowing for communication over greater distances within the body.
  • Possess branched structures to connect with other nerve cells, forming a network for signal transmission.

Muscle Cells

  • Specialized for contraction, enabling movement and bodily functions.
  • Also contain numerous mitochondria to supply energy required for contraction activities.

Root Hair Cells

  • Located on the surface of plant roots, specifically adapted for the absorption of water and minerals.
  • Develop long hair-like projections to increase surface area, enhancing water and mineral uptake from the soil.

Phloem

  • Specializes in the transportation of food (nutrients) throughout the plant.
  • Contains few subcellular structures, allowing for the efficient flow of substances.

Xylem

  • Specialized for the transport of water within the plant.
  • Characterized by a hollow center, facilitating the quick movement of water along the plant.
