Assertion : The distribution of bryophytes and pteridophytes is limited.
Reason : In bryophytes and pteridophytes water is required for the transport of male gamete and fertilisation.

Options

B. If both assertion and reason are true but reason is not the correct explanation of the assertion.
C. If assertion is true but reason is false

Answer

A

Explanation

`**` Pollinationo by water is quite rare in flowering plants and is limited to about 30 genera, mostly monocotyledons.
`**` As against this, water is a regular mode of transport for the male gametes among the lower plant groups such as algae, bryophytes and lower plant groups such as algae, bryophytes and pteridophytes.
`**` It is believed, particularly for some bryophytes and pteriodophytes, that their distributionis limited Because of the need for water for the transport of male gametes and fertilisation.
