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.
