Cell Division 0.2 Flashcards
What is the region in which cell division occurs in plants
The Meristems
What can the cells of the meristem differentiate to produce
All types of plant cells
At what point of the plants life can meristem cells differentiate
At any point in the life of the plant
What are the main meristems close to
The tip of the shoot and the tip of the root
What is another name for a fertilised egg cell
A Zygote
What must does zygote divide to produce
A multicellular organism
Why must the zygote differentiate
So that it’s cells develop features that enable them to fulfill specific roles
What are cells of the circulatory system specialised to do
Transports substances, defend the body and regulate temperature
What is the excretory system specialised to do
Remove waste products and unwanted substances also regulate the water content of the body
What is the muscular system specialised to do
Bring about movement
What is the respiratory system specialised to do
Deliver oxygen for respiration and remove waste
What is the reproductive system specialised to do
Bring about fertilisation to produce new offspring
What is the skeletal system specialised to do
To bring about movement support and protect internal structures,produce blood cells and store and release calcium
What is the palisade mesophyll cel specialised to do
Carry out photo synthesis
what is the Spongy mesophyll specialised to do
Allow gases to circulate for the exchange of gases between the leaf and the environment, carry out some photosynthesis
what is the guard cells specialised to do
Open and close the stomata to control the exchange of gases – carbon dioxide, water vapour and oxygen
what is the sieve tubes specialised to do
Transport products of photosynthesis, including sugars and amino acids, from the leaf to where they are needed
what are the xylem vessels specialised to do
Transport water and dissolved minerals from the roots, up the plant
what is the meristem specialised to do
Produce new cells as they divide
