|
What are Initial or meristematic cells? |
unspecialized cells that can divide indefinitely to produce new cells |
|
|
What are parenchyma cells? |
most common, thin primary cell walls, food storage, photosynthesis, respiration, provide structure to parts of the plant that needs frequent replacement |
|
|
What are Collenchyma cells? |
usually the primary cell wall that are thickened in some places with additional cellulose, enabling them to provide more support than Parenchyma while still allowing living stems to be flexible |
|
|
What are Sclerenchyma cell? |
thick strong secondary cell walls, hardened with lignin (makes wood hard) |
|
