Name some red blood cell adaptations
Biconcave shaped disc
No nucleus
Contains a protine called haemoglobin that binds oxygen molecules.
What are red blood cell functions
To transport oxygen around the body
Name some sperm cell adaptations
Streamed line to help glide through the body
It has a tail to help it swim easier.
Name the sperm cells function
The function is to fertilise the egg to create a fetus
Name some nerve cell adaptations
Its long
The axon is insulated to protect it’s self
What is the nerve cell function
Its function is to send signals from the brain all over the body
Muscle cell adaptations
Layer to strengthen from tears
Strong and flexible to keep it in place
What is the muscles function
To help move bones in the body
What are the adaptations of a root hair cell
Hamer like so it can stay without having to move
String to it does not tear
What is the function of the root hair cell
Block entry of particals getting in the body
What are some xylem cell adaptations
Strong and stiff to last against damage
One way system to make sure that noting gets clotted.
What is the function of the xylem.
To transport water and minerales all over the body

Cylinder like to protect organic molucals in side along with its layers.
Two way system to speed things up
What is the function of phloem cells
To transport organic molicules through the body
What are some adaptions of Photosythetic cells
Sturdy rectangle witha fixed shape to thanks to the cell wall use to hold protine for the plant
What are some of the functions of photosynthectic cells.
To create photosysthsis to help create protine
Define diffusion
A high concentration of particles to a low concentration.
Define net
Genral movement in or out.
What factors affect diffusion rates
Temperature
Increase the gradient
Shorten distance
