Plant Reproduction

• reproduction- biological process by which an organism reproduce an offspring who is biologically similar to the organism.
• sexual reproduction - involves fusion of gametes (egg + sperm) from two parents
• asexual reproduction - no gamete involved, only one parent needed
• fertilization - union of egg cell with sperm cells, resulting in formation of zygote
• asexual reproduction - one parent produces genetically identical offspring without fertilization
• procreation- sustains species so it does not become extinct
• quality improvement- allows mixing of genetic materials leading to variation among individuals in a species.
• tubers- modified roots
• buds are formed at the base of the stem.
• runners- plants that grows horizontally on the ground.
• bulb- round, swollen part of the underground stem
• vegetative reproduction- plant parts are used to reproduce
• artificial plant propagation- taking a piece from one parent plant and causing it to regenerate itself into a new plant.
• grafting- placing a portion of one plant into stem, root, or branch of another in which a way that a union will be formed and the partners will continue to grow
• budding- inserting a single bud from a desirable plant into an opening in a bark of a different plant
• spore formation- method that involves the production of spores
• perfect or bisexual or hermaphroditic plants- contains both male and female parts
• androecium- the male part of the flower, the anther, filament, and stigma
• gynoecium- female reproductive organs
