Meristems
Growth of roots
Organization of Leaves
Terms
100
perpetually embryonic tissue and allow for indeterminate growth
What are Meristems
100
are located at the tips of roots and shoots and at the axillary buds of shoots (elongate shoots and roots, a process called primary growth)
What is Apical Meristems
100
the number of zones of root growth
What is 3 zones
100
allow CO2 exchange between the air and the photosynthetic cells in a leaf
What is the stomata
100
each of the branching filaments that make up the mycelium of a fungus
What is Hyphae
200
a plant can grow throughout its life
What is indeterminate growth
200
add thickness to woody plants( a process called secondary growth, vascular cambium and cork cambium)
What is Lateral Meristems
200
The three zones of root growth
What are o Zone of cell division o Zone of elongation o Zone of maturation
200
each stomatal pore is flanked by 2 which regulate its opening and closing
What are guard cells
200
networks of branched hyphae adapted for absorption
What is Mycelium
300
plant organs cease to grow at a certain size
What is determinate growth
300
accumulates as wood and consists of tracheid’s, vessel elements (only in angiosperms), and fibers
What is Secondary Growth (xylem)
300
the innermost layer of the cortex
What is the Endodermis
300
ground tissue in a leaf/ is sandwiched between the upper and lower epidermis
What is the Mesophyll
300
Allows the cell wall of Fungi to withstand the digestive enzymes
What is Chitin
400
adds layers of vascular tissue called secondary xylem (wood) and secondary phloem
What is Vascular Cambium
400
formed in the spring, has thin cell walls to maximize water delivery
What is Early Wood
400
the outermost cell layer in the vascular cylinder
What is the Pericyle
400
The more dense and tightly organized layer of the mesophyll
What is palisade layer
400
is the union of two parent mycelia
What is Plasmogamy
500
replaces the epidermis with periderm, which is thicker and tougher
What is Cork Cambium
500
formed in late summer, has thick-walled cells and contributes more to stem support
What is Late Wood
500
is a dome-shaped mass of dividing cells at the shoot tip
What is the Apical meristem
500
The more loosely organized layer of the mesophyll
What is the Spongy layer
500
the haploid nuclei fuse to produce diploid cells
What is Karyogamy
