Specialised Cells Flashcards
State animal specialised cells
Red blood cells
Nerve cell
Sperm cell
Ciliated cell
State the red blood cell structure
No nucleus
Biconcave shape
Large surface area
Flexible
State the red blood cell function
Carries oxygen from the lungs and the body and carbon dioxide from the body to the lungs
State how a red blood cell structure help function
No nucleus = less organelles, more space transporting oxygen and carbon dioxide
Biconcave,large urbane area = more space for transporting gases
Flexible + move and bend through capillaries
State the nerve cell structure
Extremely long
May branches
Long axis converted in fat to prevent electrical impulses
Sates the nerve cell function
To carry nerve impulses around your body and send and receive signals from the brain
How does a nerve cell structure help function
Cells are long and have many branches that allow signals to be sent around the body
What is a sperm cell’s function
To carry the father’s DNA
What is a sperm cell’s structure
Long tail
Enzymes
Mitochondria
How does a sperm cells structure help function
Long tail = to swim towards the egg
Enzymes = to break down the protective layer of the egg
Mitochondria = to move
Nucleus = has father’s DNA to pass on to offspring
What is ciliated structure
Line in all air passage ways down to the lungs
Tiny hair called cilia
What is ciliated function
Hair are coated with mucus and trapped dust and pushes it back up to the throat to be swallowed
How does ciliated structure help function
Movement of the cilia propel mucus and dust away from the lungs
What are the plant specialised cells
Palisade cells
Root hair cells
Muscle cells
What is palisades structure
Found on top of a leaf
Layer above cell is transparent
Packed with chloroplast
