Plant Anatomy Flashcards
what are the 3 embryonic plant tissues?
- protoderm
- procambium
- ground meristem
what does the protoderm develop into?
plants covering
what does the procambium develop into?
plants vascular tissue
what does the ground meristem develop into?
tissue between covering and vascular tissue
what are the 3 mature tissues?
- dermal
- vascular tissue
- ground tissue
what is the dermal tissue?
plants skin/protective coating
may develop other special parts like root hairs and shit
what does the vascular tissue do?
it conducts fluids and is responsible for secondary growth
wha is the ground tissue?
fills space between the dermal/vascular
- can perform photo synthesis
- stores materials
what are the 3 common cells?
- parenchyma
- collenchyma
- sclerenchyma
what are some characteristics about parenchyma
- most common cell
- has thin primary cell wall
- has all normal plant organelles
what are the functions of parenchyma cells?
- photosynthesis
- respiration
- food/water storage
what are some characteristics of collenchyma cells?
- thickened primary cell walls
- grouped in strands for flexible support
what are some characteristics of sclerenchyma cells?
- support plants by having a thicc, stiff;), secondary cell wall
- dead at maturity
how does germination start?
when the seed coat is…
- worn away
- burned
- broken
during germination, the aleurone starts to produce alpha-amylase, which does what?
breaks down starch into sugars
during germination, the radicle and the hypocotyl do what?
elongate and leaves begin to develop
growth is __________ because do embryonic tissues called meristems.
indeterminate
where are primary and secondary meristem growths?
primary- apical
secondary- lateral
what are two characteristics of meristem cells?
- unspecified
- divide to make new cells
