ADVERTISEMENTS:
The upcoming discussion will update you about the difference between Taxales and Coniferales.
Difference # Taxales:
1. Resin canals are absent in wood or leaves in taxales.
2. Ovule develops solitary in it.
ADVERTISEMENTS:
3. In taxales, ovules are enclosed by a specialised outgrowth called aril.
4. Ovule is borne terminally on the floral axis in taxales.
5. Taxales lack cone-like organisation.
6. Female flowers develop singly in the axils of bracts on the vegetative shoots in taxales.
ADVERTISEMENTS:
ADVERTISEMENTS:
7. Male flowers are radially symmetrical in it.
8. In taxales, male flowers have perisporangiate microsporophyll’s.
9. Pollen grains are wingless in taxales.
10. Embryo with two cotyledons.
Difference # Coniferales:
1. In coniferales, resin canals are present in the leaves, cortex and sometimes even in the wood.
2. Ovules are 2 to many and only rarely one in coniferales.
3. Ovules are not arillate in it.
4. In coniferales, ovules develop terminally on the lateral stalk like appendages that develop from the cone axis.
ADVERTISEMENTS:
5. Conifers possess distinct cones or strobili.
6. Female flowers develop in the axils of bract scales that develop on the cone axis in coniferales.
7. Male flowers are dorsiventral in it.
8. In coniferales, male flowers have hypo-sporangiate microsporophyll’s.
ADVERTISEMENTS:
9. Most of the conifers have winged pollen grains in taxales.
10. Embryo with 2 to many cotyledons.
