Plant tissue and organ Flashcards
what is the hierarchy of cellular architecture
cell, tissue, organ, organ system
what are the three types of tissues
epidermal tissue, ground tissue, vascular tissue
what happens in the primary growth
division of the apical meristem, formation of primary tissue
what happens in the secondary growth
thickening of the stem, root
from apical meristem what are the three primary meristem
protoderm, ground meristem, procambium
where is the apical meristem
in roots and shoots
what are the two types of secondary meristem
vascular cambium, cork cambium
what does the vascular cambium
divide by two and enlarge the stem
what are the stomata
guard cells, open and close
where are the epidermal tissue
surface of leaf, herbaceous stem, young roots
what are the three types of cells in ground tissues
parenchyma, collenchyma, sclerenchyma
describe the cell wall of parenchyma cell
only primary cell wall made of cellulose
what are the metabolic function of parenchyma cells
photosynthesis, storage, secretion
what is the function of collenchyma cell
elongation of younger tissue
where do we find collenchyma cells
under the epidermis cells
