uses energy from ATP to pump hydrogen ions out of the cell
proton pump
the process in which energy stored in the form of a hydrogen ion gradient across a membrane is used to drive cellular work
chemiosmosis
associated with the transition from vegetative growth to flowering
mersitem identity genes
the morphological changes that arise from transitions in shoot apical meristem activity
phase changes
→ the form of the stele of the root in angiosperms.
vascular cylinder
→ an organ consisting of an alternating system of nodes and internodes.
stems
a protective vein enclosing which consists of one or more layers of cells
bundle sheath
the vascular tissue of leaves
veins
the parts of the root and shoot systems produced by apical meristems
primary plant body
the cell contents exclusive of the cell wall
protoplast
several types of tissues that together carry out particular functions
organ
the points at which leaves are attached
nodes
consists of stems and leaves
shoot system
the form of the stele of the root in angiosperms
vascular cylinder
connections from vascular bundles in the stem
leaf traces
→ {tonoplast} regulates molecular traffice between the cytosol and the other vacuolar contents
vacuole membrane
charge separation across the membrane contributes to a voltage called this, its another form of potential energy that can be harnessed to perform cellular work
membrane potential
Embryonic plant tissue in the tips of roots and in the buds of shoots that supplies cells for the plant to grow in length.
apical meristem
Thinner regions in the walls of tracheids and vessels where only primary walls are present.
pits
A primary meristem that gives rise to ground tissue in plants.
ground meristem
→ A point along the stem of a plant at which leaves are attached..
