Question

question 4 (1 point)
which of the following is a method of sexual propagation?
o a layering
o b from seeds
o c stem cuttings
o d division

question 5 (1 point)
sexual propagation in flowering plants typically involves the combination of male and female gametes through what process?
o a division
o b pollination
o c germination
o d transpiration

question 6 (1 point)
bending a branch of a shrub to the ground and covering part of it with soil to encourage new roots to form is an example of which propagation technique?
o a division
o b layering
o c cuttings
o d reproduction

Explanation:

• Question 4: Sexual propagation involves the union of gametes. Seeds are formed from the fertilization of gametes (sexual reproduction), while layering, stem cuttings, and division are asexual propagation methods (no gamete union).
• Question 5: Pollination is the transfer of pollen (male gametes) to the stigma (where female gametes are located in flowering plants), which is a key step in the combination of male and female gametes for sexual propagation. Division is a form of asexual propagation, germination is the growth of a seed into a plant, and transpiration is water loss from plants.
• Question 6: Layering is a propagation technique where a branch is bent to the ground and covered with soil to encourage root formation. Division involves splitting a plant into parts, cuttings use a part of the plant (like a stem) to grow a new plant, and reproduction is a general term not specific to this technique.

Answer:

• Question 4: B. From seeds
• Question 5: B. Pollination
• Question 6: B. Layering
