Types of plant cells Flashcards
What are the three types of plant cells?
parenchyma
collenchyma
sclerenchyma/ stone cells
How do the size differ?
Parenchyma- largest
collenchyma- slightly smaller than parenchyma cells
sclerenchyma- smallest
How do the shapes differ?
Parenchyma- thin walls with roundish shapes
collenchyma- square with thicker corners
sclerenchyma- round with thick cell walls
Where are parenchyma cells found?
organs and soft tissues
Where are collenchyma cells found?
growing shoots and leaves
Where are sclerenchyma cells found?
seeds, wood, hypodermis of leaves
What is the function of parenchyma cells?
photosynthesis
storage of water and nutrients
gas exchange
What is the function of collenchyma cells?
mechanical support
elasticity
What is the function of sclerenchyma cells?
mechanical support
What are plant fibers used for?
clothing, dietary fibers
What are plant fibers?
Found in thick cell walls, they provide structure and support
