Back 31

Amyloplast

Front 32

is the flow of the cytoplasm inside the cell, driven by forces from the cytoskeleton. It is likely that its function is, at least in part, to speed up the transport of molecules and organelles around the cell.

Back 32

cytoplasmic streaming or cyclosis.

Front 33

represent waste products, which are solid and secondary

Back 33

Ergastic substances

Front 34

these are cells that are alive at maturity; they make up the portion of the primary plant body, characterized by having a thin-walled cell. They function in metabolic activities.

Back 34

Parenchyma cells

Front 35

parenchyma cells containing chlorophyll

Back 35

Chlorenchyma

Front 36

parenchyma cells containing air spaces produced by dissolution, separation and tearing of cortex cell wall

Back 36

Aerenchyma

Front 37

these are cells alive at maturity also and give support on young parts of the plant shoot, characterized by having elongated cells that have thicker primary walls than parenchyma cells, though the walls are unevenly thickened.They

Back 37

Collenchyma cells

Front 38

these are cells that are dead at maturity mainly function in mechanical support due to thick lignified secondary walls which contain large amounts of cellulose and lignin.

Back 38

Sclerenchyma
