specialized cells generalities
– Specialized cells have different shapes and structures, a feature known as this.
What is cell specialization?
Another name for a nerve cell is this.
What is a neuron?
The root hair cell is found on this part of a plant.
What is the root?
The tiny hair-like structures on these cells are known as this.
Cilia
This disc-shaped cell is designed to maximize surface area for oxygen exchange.
A red blood cell?
This process involves cells developing different functions to support a complex organism.
What is differentiation?
This long extension of a neuron carries impulses away from the cell body.
an axon?
This structure in the root hair cell increases its surface area, aiding in water absorption.
the hair-like extension?
Ciliated cells line this tract in the human body, helping to remove dust and pathogens.
Respiratory tract?
The iron-rich protein in red blood cells that binds to oxygen.
hemoglobin?
Red blood cells, root hair cells, and ciliated cells are all types of these cells.
Specialized cells?
Nerve cells transmit messages using these electrical signals.
What are impulses?
Root hair cells absorb minerals and water from this source.
the soil?
These cells work to move mucus and trapped particles towards this body part to be expelled.
The throat?
The lack of this organelle gives red blood cells more room for oxygen but limits their lifespan.
The nucleus?
advantage of Specialized cells is that they are
unique in their structure, and each type is adapted to perform a specific function.
These structures at the end of nerve cells allow communication with other neurons.
What are synapses?
These cells lack this organelle, as they do not perform photosynthesis.
Chloroplast
Cilia move in this coordinated way to ensure efficient particle movement.
wave-like motion?
This process, done in red blood cells, involves delivering oxygen to tissues and removing carbon dioxide.
Gas exchange?
This is the reason that red blood cells and nerve cells have different functions
Different genes are activated?
How do the branches of nerve cells help them connect with other cells?
The branches allow nerve cells to communicate with multiple cells at once, making the transfer of information quick and efficient
Why is a large surface area important for root hair cells?
The larger surface area increases the amount of water and nutrients they can absorb, giving the plant everything it needs to grow.
Why do you think having cilia is important for cells in the respiratory tract?
The cilia help to trap and move particles, like dust and bacteria, out of the respiratory system, preventing infection and keeping the airways clear
Why do you think the flexibility of red blood cells is helpful for their function?
The flexibility allows them to squeeze through tiny blood vessels and deliver oxygen efficiently
