plant primary growth

parenchyma

thin primary cell wall, flexible, once mature is living, photosynthesis, storage, secretion, in leaf , fruit flesh

ex: filler and factory

dermal tissue

outer protective barrier, prevents water loss and pathogens from entering, contains the epidermis, cuticle, guard cells, root hairs, trichomes

vascular tissue

long distance transport of materials, contains the xylem and phloem

collenchyma

uneven thickened primary wall, flexible support, no secondary wall, once mature is living, stems

Ex: the tendons, cartilage

ground tissue

everything else! storage photosynthesis support. contains the pith and cortex

sclerenchyma

thick secondary cell wall, dead at maturity, rigid structural support, forms wood

ex: armor

xylem

transports water and minerals up

phloem

transports sugars and photosynthate

apical meristem

where does primary growth occur ( lengthening of roots and shoots)

shoot apical meristem

located at apical bud, produces leaf primordial and axillary bud primordia

what does the shoot apical meristem differentiate into

protoderm (dermal) procambium (vascular) and ground meristem (ground)

root apical meristem

at root tip, covered and protected by the root cap
