Which of the following is a critical step to minimize transplant shock?

Acclimating the plant to outdoor conditions gradually before transplanting

The emergence of a radicle from the seed marks which stage of germination?

Initial growth

Which asexual propagation method involves separating naturally formed vegetative structures from the parent plant?

Division

Xylem tissue in plants is primarily responsible for:

Transporting water and dissolved minerals from the roots to the rest of the plant

Phloem tissue in plants is primarily responsible for:

Transporting sugars produced during photosynthesis to other parts of the plant

 A fertilizer with an N-P-K ratio of 10-20-10 is considered high in:

Phosphorus

Which of the following is NOT a principle of Integrated Pest Management (IPM)?

Relying solely on chemical pesticides for control

Seed scarification aims to:

Break down the physical barrier of the seed coat to allow water imbibition

Which of the following is a common example of propagation by cuttings?

Rooting a section of a stem in water or soil

Yellowing of older leaves, often starting at the tips and moving inward, can be a symptom of:

Nitrogen deficiency

Describe three important steps to take when transplanting a seedling from a small container to a larger pot to ensure successful establishment 

Gently remove the seedling from the container, plant the seedling at the same depth as it originally was, and water regularly after transplanting.

Explain the three essential environmental factors that influence seed germination and briefly describe how each of the factor affects the process 

Water is crucial for seed imbibition, proper temperature is needed for germination, and oxygen is needed for respiration.

Describe the four main components of an Integrated Pest Management (IPM) program and explain why this approach is considered more sustainable than relying solely on chemical pesticides.

1. Monitoring pest populations

2. Establishing action thresholds

3. Using a variety of control methods

4. Evaluating the effectiveness of control measures

IPM is more sustainable because it minimizes reliance on chemicals.
