Sexual or Asexual?
This type of reproduction involves seeds and pollination.
What is sexual reproduction?
This is where leaves attach to the stem.
What is a node?
This prevents cuttings from drying out.
What is water?
This structure is used to control temperature and humidity.
What is a greenhouse?
Asexual reproduction requires pollination.
What is false?
This type of reproduction produces a clone of the parent plant.
What is asexual reproduction?
This is the best place for new roots to form on a cutting.
What is a node?
This gas is needed for root respiration.
What is oxygen?
Why might a nursery use cuttings instead of seeds?
To keep plant traits the same.
Roots form at nodes, not internodes.
What is true?
Why is a plant grown from a cutting genetically identical to the parent?
Because no new genetic material is mixed.
Why should you cut just below a node when propagating?
Because that area can form roots.
Why is warmth important for propagation?
It speeds up cell growth and root formation.
Why might a farmer prefer seed-grown crops in some situations?
For genetic diversity or disease resistance.
Clones always have more variation than seed-grown plants.
What is false?
A farmer wants uniform strawberries. Should they use seeds or runners, and why?
Runners, because they are clones with identical traits.
Why should extra leaves be removed from a cutting?
To reduce water loss.
What problem occurs if a cutting is kept too wet?
Lack of oxygen/root rot.
A cutting keeps wilting even though it is watered. What is likely missing?
Oxygen.
Cuttings need light immediately to form roots.
What is false? (roots form first)
Explain one advantage and one disadvantage of sexual reproduction in agriculture.
Advantage: genetic diversity. Disadvantage: less uniform crops.
Describe the full path of how a cutting becomes a new plant.
It forms roots at the node, absorbs water and oxygen, and begins new growth.
Explain how all three conditions (water, oxygen, warmth) work together.
Roots need moisture, air, and proper temperature to grow and survive.
You are propagating a rare plant. Would cloning or seeds be safer for preserving it long-term? Explain.
Seeds for diversity, clones for exact preservation (discussion answer).
Sexual reproduction is slower but more important for long-term crop survival.
What is true? (Explain using genetic diversity.)
