Where do the Casparian bands occur?
Epidermis
Endodermis
Pericycle
Phloem
Out of diffuse porous and ring porous woods, which is correct?
Ring porous wood, carries move water for short period
Diffuse porous wood, carries more water
Ring porous wood carries more water when need is higher
Diffuse porous wood is less specialized but conducts water rapidly throughout

pollen tube of pinus
cytoplasm of chlorella
mycelium of a green mould such as Aspergillus
spore capsule of a moss
An organized and differentiated cellular structure having cytoplasm but no nucleus is

A leaf primordium grows into the adult leaf lamina by means of
apical meristem
lateral meristem
marginal meristem
at first by apical meristem and later largely by marginal meristem
Death of protoplasm is a pre-quisite for a vital function like
transport of sap
transport of food
absorption of water
gaseous exchange
The length of different internodes in a culm of sugarcane is variable because of
shoot apical meristem
position of axillary buds
size of leaf lamina at the node below each internode
intercalary meristem
The annular and spirally thickened conducting elements generally develop in the protoxylem when the root or stem is
maturing
elongating
widening
differentiating
A narrow layer of thin walled cells found between phloem/bark and wood of a dicot is
cork cambium
vascular cambium
endodermis
pericycle
Passage cells are thin walled cells found in
endodermis of roots facilitating rapid transport of water from cortex to pericycle
