If a plant is placed inverted, the root will still grow downward due to gravitropism, while the shoot will grow upward. This response demonstrates the plant’s ability to adapt to its environment regardless of orientation.
The conditions required for seed germination include moisture, warmth, and oxygen. Moisture activates enzymes, warmth provides the ideal temperature for growth, and oxygen is essential for respiration, allowing the seed to convert stored nutrients into energy.
Yes, a pot with tightly packed soil or a sealed container can limit air availability for seeds. Poor soil aeration prevents oxygen from reaching the seeds, hindering their respiration and overall germination process.
No, seeds in all pots may not receive equal amounts of air, water, and sunlight. Factors like pot placement, soil drainage, and pot material can affect the availability of these essential resources for germination.
