Part I Basics Of Sexual Propagation Flashcards
What is sexual propagation in plants?
The natural process of plant reproduction involving male and female gametes.
What are the male and female gametes involved in plant reproduction?
Pollen (male) and ovule (female).
What is the main outcome of sexual propagation?
Seed formation.
How does seed propagation differ from asexual propagation?
Sexual propagation involves seeds; asexual uses cuttings, grafting, etc.
List two advantages of sexual propagation.
Genetic diversity, economical.
Name two disadvantages of sexual propagation.
Time-consuming, variability.
Why is genetic diversity important in plant propagation?
It promotes adaptation and resilience.
What makes seeds an economical propagation method?
Seeds are cheaper and widely available.
Why is sexual propagation time-consuming?
Germination and maturity take time.
How do environmental conditions affect seed propagation?
Seeds need specific environmental conditions to grow.
What is the purpose of a seed coat?
Protects the seed from damage and stress.
What role does the endosperm play in seed development?
Provides nourishment to the developing embryo.
What is the function of the embryo in a seed?
Contains the genetic blueprint for plant growth.
How does the seed coat protect the seed?
Acts as a barrier against pathogens and harsh conditions.
What nutrients are stored in the endosperm?
Carbohydrates, proteins, and fats.
What is the significance of the embryo’s genetic blueprint?
Guides the seed’s growth into a mature plant.
Define seed dormancy.
A natural mechanism preventing germination until conditions are favorable.
What is the advantage of seed dormancy for plant survival?
Ensures seeds only sprout in ideal conditions.
Name two types of seed dormancy.
Physiological and physical dormancy.
What causes physical dormancy in seeds?
A hard seed coat preventing water and oxygen entry.
