Study Notes
Plant Reproduction
- Plant reproduction can be asexual or sexual
- Asexual reproduction creates genetically identical offspring through vegetative propagation
- Examples of vegetative propagation include bulbs, cuttings, tubers, runners, and rhizomes
- Sexual reproduction produces variable offspring, creating diversity within populations
- This variation helps plants better survive and adapt
- Sexual reproduction, through genetics, allows plants to develop their own uniqueness within the species.
- Plants can reproduce via the process of vegetative propagation, using various methods to create new plants (from the part of an existing plant) that are genetically identical to the original plant
- Vegetative reproduction results in genetically identical offspring.
- Plants use a variety of methods for vegetative propagation, including runners, bulbs, tubers, and rhizomes
- Example of plants that use vegetative propagation are wild strawberries (runners), potatoes (tubers), and onions (bulbs)
- Plants like mosses also reproduce using spores.
- Cannabis, for example, can reproduce sexually and asexually.
- Hydroponics is a technique used for growing plants without soil, using water-soluble nutrient solutions.
- Many plants reproduce from spores, not seeds, like mosses.
- Some plants (like cannabis) can reproduce asexually or sexually.
- Fruit is developed from the flower's ovary after pollination and fertilization. The ovules become the seeds, and the ovary becomes the fruit. Seeds are dispersed, containing plant embryos that develop into new plants.
- Fruit can be simple, aggregate, and multiple. Different types of fruits have various developmental characteristics.
- Cultivars are plants grown from cuttings, grafting, or tissue cultures to maintain the parent plant's characteristics.
- Some plants (like cannabis) reproduce using asexual reproduction, resulting in plant clones genetically identical to the parent plant. This contrasts with sexual reproduction, which creates variation.
- Different types of fruits (e.g., tomato, cucumber, sunflower) have distinct structures and development after fertilization.
- Layering is a method of vegetative propagation where a branch is bent to the ground and covered with soil, encouraging root development.
- Grafting combines parts of different plants to create a new plant. A scion (twig) from one plant is attached to a stock (root system) of another plant.
Alternation of Generations
- Plants alternate between a haploid and diploid phase in their life cycle
- The haploid phase produces gametes (sex cells) and is called the gametophyte generation
- The diploid phase produces spores and is called the sporophyte generation
- This cycle is essential for plant reproduction and survival.
- The life cycle of a moss demonstrates this alternation of generations
- In ferns, the sporophyte is dominant.
- The gametophyte is the dominant stage for mosses.
- The process of meiosis produces spores.
- Stages involved in the alternation of generations include fertilization, zygote development, sporophyte phase, meiosis, spore dispersal, gametophyte phase, gamete formation
- Different plant types (like mosses and ferns) have variations in this cycle.
- The different types of fruits in plants display how they are reproduced.
Types of Pollination
- Pollination can be abiotic (via wind) or biotic (via animals like insects, birds, and bats)
- Self-pollination occurs within the same plant, does not increase genetic diversity
- Cross-pollination occurs between different plants, increasing genetic diversity
- Certain plants can have different strategies for reproduction, and this can increase survival abilities.
Flower Structure and Types
- Flowers have specific parts including the stamen (male), filament, anther, pistil, stigma, style, and ovary
- Perfect flowers contain both male and female reproductive parts
- Imperfect flowers are either male or female
- Different types of flowers—hermaphroditic, monoecious, and dioecious—can have varied reproductive strategies.
- Perfect flowers contain both male (stamen) and female (pistil) parts.
- Imperfect flowers are flowers that lack either male or female parts.
- Monoecious flowers have both male and female flowers on the same plant.
- Dioecious flowers have male flowers on one plant and female flowers on a separate plant..
- Hermaphroditic flowers have both male and female organs in the same flower.
- Flowers need reproductive strategies to increase fertilization potential.
- The parts of a flower are named as follows: 1. stigma, 2. style, 3. pollen tube, 4. ovary, 5. ovule, 6. receptacle ,7. petal, 8. sepal, 9. anther, 10. filament
