What are examples of asexual reproduction in plants?
Examples include:
* Cuttings
* Grafting
* Layering
* Division
* Runners
* Bulbs
Asexual reproduction allows plants to reproduce without seeds, leading to genetically identical offspring.
What are the advantages of asexual reproduction in plants?
Advantages include:
* Rapid population increase
* No need for pollinators
* Genetically uniform offspring
* Preservation of successful traits
This method is beneficial in stable environments where the parent plant is well adapted.
What are the disadvantages of asexual reproduction in plants?
Disadvantages include:
* Lack of genetic diversity
* Susceptibility to diseases
* Vulnerability to environmental changes
Genetic uniformity can lead to population collapse under changing conditions.
What is the function of synergids?
Synergids help guide the pollen tube to the ovule and provide nutrients to the developing embryo sac.
They are located near the egg cell in the ovule.
What is the function of the anther?
The anther produces and releases pollen grains, which contain male gametes.
It is part of the stamen in flowering plants.
What is the function of the endocarp?
The endocarp is the innermost layer of the pericarp, surrounding the seed and providing protection.
It can be hard or soft depending on the type of fruit.
What is the function of the exocarp?
The exocarp is the outermost layer of the pericarp, serving as the skin of the fruit.
It often provides protection against pests and environmental factors.
What is the function of the mesocarp?
The mesocarp is the middle layer of the pericarp, often fleshy and providing nutrients to the fruit.
It is typically the part we consume in many fruits.
What is the function of the pericarp?
The pericarp is the part of the fruit formed from the ovary wall, protecting the seeds and aiding in their dispersal.
It consists of three layers: exocarp, mesocarp, and endocarp.
What is the function of the style?
The style connects the stigma to the ovary and allows the pollen tube to grow to the ovule.
It is part of the pistil in flowering plants.
