Mycorrhiza is a mutualistic interaction in which a fungus and a root involved. For eg. Boletus (fungus) and Pinus (root). The root provides food and shetter to the fungus. The fungus helps the plant in solubilization and absorption of minerals, water uptake and protection against pathogenic fungi.

In which of the following excurrent stem found?
1 Cycas
2 Pinus
3 Mango
4 Wheat
Explanation:
An excurrent stem found in the plant Pinus. The side branch grows in an acropetal manner in which old flowers are arranged in the lower side and young flowers are at the upper side. A tree takes a pyramidal form due to development of racemose branching, it is excurrent e.g. pinus.

Which one of the following statements is false?
1 Stomatal movement is governed by many factors including potassium
2 All enzymes are proteins, but all proteins are not enzymes
3 All factors which affect respiration affect photosynthesis as well, but its reverse is not true.
4 All following plants are characterized by seed development but all seed plants are not flowering plants
Explanation:
All the angiosperms are seed bearing plants. But there are also some seed bearing plants which are not angiosperms. The seed bearing plants which have a seed cover are called angiosperms and some seed bearing plants do not have a seat cover which are called gymnosperms. The plant angiosperms are enclosed inside fruits- they have non-motile gametes. These gametes have dissmilar morphological structures.

Resin duct of gymnospermous stem is an example of:
1 lysigenous cavity
2 lysogenous cavity
3 shizogenous cavity
4 shizolysigenous cavity
Explanation:
The Schizogenous cavities are formed by the splitting up of common walls and the separation of masses of cells from one another. The resin ducts arise as Schizogenous intercellular spaces due to the disjoining of parenchyma cells. Resin ducts ae formed due to wounding. Examples of this schizogenous cavity or ducts of asteraceae and apiaceae, secretory cavities of eucalyptus etc.
