Plant Reproduction
Cards (81)
- involves the union of gametes (egg cell and sperm cell) through fertilization.
- involves the creation of cloned offspring from a parent organism.
- houses the structures for sexual reproduction
- four main parts of a plants reproductive system
- Pistil/carpel and stamen
- Petals and sepals
- Parts of the stamen
- Production site of pollen
- Supports the anther
- Parts of pistil/carpel
- Receiving site of pollen
- Supports the stigma
- Where fertilization takes place
- Becomes the seed
- Perfect flowers are also called
- Imperfect flowers are also called
- _____ flowers have both pistil and stamen parts
- ____ flowers either only have the pistil or the stamen
- Two types of imperfect/dioecious flowers:
- Contains all 4 parts: pistil, stamen, petals, sepals
- Lacks at least one of the 4 main parts
- ____ flowers are automatically incomplete flowers
- Process of transferring pollen from an anther to a stigma
- Pollination is mainly through ____
- In abiotic means of pollination, the 2 main agents are ____ and ____
- Pollination sequence/process
- Dominant stage is a multicellular haploid stage
- Produces gametes that eventually fuse to form unicellular zygotes. Each zygote then undergoes meiosis to become haploid, after which it undergoes mitosis to become the multicellular organism.
- Gametes are not the direct result of a meiotic division
- ▪ Multicellular haploid (gametophyte) stage that produces gametes. ▪ These gametes fuse to produce a zygote that undergoes mitosis to produce a multicellular sporophyte. ▪ Within a part of the sporophyte called the capsule, cells undergo meiosis to produce meiospores. ▪ These spores are eventually released and germinate by dividing mitotically to become a multicellular gametophyte
- Dominated by the diploid stage
- ____ and ____ show alternation of generation
- All the plants showing sexual reproduction alternate between two multicellular stages, the ____ and ____
- After landing on a receptive stigma, a pollen grain produces a pollen tube that extends between the cells of the style toward the ovary
- Results from the discharge of two sperm from the pollen tube into the embryo sac
- One sperm fertilizes the egg, and the other combines with the polar nuclei, giving rise to the triploid food-storing ____
- Embryo and its food supply are enclosed by a hard, protective ____
- In some eudicots, such as the common garden bean, the embryo consists of the ____ attached to two thick ____
- Below the cotyledons the embryonic axis is called the ____ and terminates in the ____
