Flowers and Reproduction
Asexual Reproduction
Fragmentation
A large spreading or vining plant grows to several meters in length, and individual parts become self-sufficient by establishing adventurous roots.
Sexual Reproduction
The Plant Life Cycle
Diploid adults have sex organs that produce haploid sex cells called gametes, either sperms or eggs, by meiosis.
Trees, shrubs, and herbs are just one phase of the plant life cycle, called the sporophyte phase or sporophyte generation.
A critical factor is that sporophyte are always diploid, and have organs capable of undergoing meiosis

Incomplete flowers are when flowers lack one or two of the four basic floral appendages. #
