Plant reproduction, pollination and fertilization Flashcards
The process of sexual reproduction in plants consists of several chronological steps:
- Production of flowers
- Pollination
- Fertilization (produces seeds)
- Formation of fruits
The sperm of plants is contained in the _____ ____, therefore it is necessary for the pollen to be transferred to another plant for sexual reproduction to take place.
pollen grains
It is defined as the transfer of pollen from the male part of a flower to the female part of the flower, usually the flower on another plant.
Pollination
Some species of plants will ___________ (pollen is transferred to the stigma of the same flower); however, the majority of flowering plants ___________(are pollinated by another plant).
self-pollinate, out-cross
It is important because that’s how plants are able to adapt to new challenges. If all plants in a population have the same genetic makeup (clones), as is the case with plants that reproduce mainly asexually (e.g.bananas), they may all get killed by a disease.
