1 Apophysis is the basal fertile part of the capsule in Funaria.
2 Apophysis is the apical sterile part of the microsporophyll in Cycas.
3 Apospory is the development of sporophyte from vegetative cells of the gametophyte.
4 Apogamy is the development of gametrophyte from the vegetative cells of the sporophyte.
Explanation:
Apophysis is the apical sterile portion of the microsporophyll in Cycas. Apospory is the formation of gametophyte directly from sporophyte. Apogamy is the formation of sporophyte directly from gametophyte. Apophysis present in the microsporophyll of cycas. It is a wedge-shaped and dorsoventrally flattened structure. The basal part of the apophysis is sterile. The middle part is fertile and the apical part is a sterile region. The terminal part which has an expanded sterile tapering portion is called the apophysis.

A gymnosperm, popularly known as sagopalm, possess two cotyledons, but is not classified as dicotyledons why?
1 Due to production of largest multiciliate. mononucleate sperm
2 Pollination takes place by wind
3 Pollen grain are shed at 3-celled stage
4 Due to open and exposed ovules on megasporophyll
Explanation:
Cycas is popularly known as sagopalm, and possess two cotyledons. It is member of order cycadales of division gymnosperm. - The later are characterized by presence of exposed ovules an megasponphyll, i.e., naked seed, therefore, Cycas is not include in dicotyledons.

The type of pollination in Cycas is
1 entomophily
2 hydrophily
3 anemophily
4 malacophily
Explanation:
In cycas, the 3-celled microspore is shed off in the air after the dehiscence of the sporangium. They are very light-weight and are carried by air current (anemophily). Entomophily- Entomophily or insect pollination is a form of pollination where by pollen of plant especially but not only of flowering plant is distributed by insect. Hydrophily- Pollination of flowering plant by water is known as hydrophiliy. E.g. - Valisenaria and zoostera. Malacophily- Pollination of flower by slugs and snails is called malacophily. E.g. - Lemna.

In gymnosperms, the ovules are
1 Naked unitegmic
2 covered multitegmic
3 Bitegmic
4 Covered unitegmic
Explanation:
Unitegmic is the most advanced condition. It is usually seen that the less number of integuments present in the ovule, the more advanced integuments in its properties and function. An integument is a protective layer that surrounds the ovule of the plant. There are four types of integuments on the basis of the number of layers present in it. Unitgmic, Bitegmic, Tritegmic, Ategmic.
