What is seed formation?
Click to flip
Seed formation is the process by which seeds are created in flowering plants after fertilization, beginning with pollen reaching the ovule and culminating in a mature seed.
Click to flip
What are the main parts of a seed?
Click to flip
The main parts of a seed are the seed coat, endosperm, and embryo which includes the cotyledons, epicotyl, and radicle.
Click to flip
What role does the seed coat play in seed formation?
Click to flip
The seed coat is the protective outer layer that shields the seed from physical damage and disease, and aids in the dormancy and germination process.
Click to flip
What is the function of the endosperm in a seed?
Click to flip
The endosperm provides nutrients to the developing embryo, often containing starches, proteins, and oils that support initial growth stages after germination.
Click to flip
How does fertilization lead to seed formation?
Click to flip
Fertilization in plants involves the fusion of male and female gametes, triggering the development of an embryo and eventually a seed within the ovule.
Click to flip
What is the role of the cotyledons in a seed?
Click to flip
Cotyledons, or seed leaves, store nutrients and aid initial growth by providing energy to the developing seedling before true leaves emerge.
Click to flip
Why is water necessary for seed germination?
Click to flip
Water is essential for activating enzymes in the seed, initiating metabolic processes crucial for breaking dormancy and allowing the seed to sprout.
Click to flip
What environmental conditions favor seed germination?
Click to flip
Conditions favorable for seed germination typically include adequate water, suitable temperature, oxygen availability, and sometimes light.
Click to flip
How do seeds ensure species propagation?
Click to flip
Seeds facilitate species propagation by allowing plants to disperse offspring over distances and endure unfavorable conditions until germination is viable.
Click to flip
What is seed dormancy, and why is it vital?
Click to flip
Seed dormancy is a survival mechanism that delays germination until conditions are favorable, ensuring the seed's viability over time.
Click to flip
How are seeds dispersed?
Click to flip
Seeds are dispersed through various mechanisms, including wind, water, animals, and mechanical means, aiding in spreading plants to diverse areas.
Click to flip
What significance does the radicle have in a seed?
Click to flip
The radicle is the first part of a seed to develop into the primary root, anchoring the plant and beginning nutrient and water uptake.
Click to flip
What triggers the breaking of seed dormancy?
Click to flip
Environmental cues such as temperature changes, light exposure, moisture, and in some cases, scarification, can break seed dormancy and initiate germination.
Click to flip
How does temperature influence seed germination?
Click to flip
Temperature impacts enzyme activity and metabolic rates in seeds, determining the success and speed of germination.
Click to flip
What are the types of seed dispersal?
Click to flip
Seed dispersal types include anemochory (wind), hydrochory (water), zoochory (animals), and autochory (self-dispersal).
