Question

1. The flower of an angiosperm that relies on wind to disperse pollen will be:

a) colorful. b) odiferous. c) large. d) small.

2. Why might asexual reproduction typically result in local colonization, while the products of sexual reproduction are typically dispersed? Select all that apply.

a- Vegetative propagation is more efficient than sexual reproduction when the current generation is well-adapted to the local environment.

b - The variation resulting from meiosis and the union of gametes means some individuals will have a chance of colonizing diverse distant environments successfully.

c- Asexual reproduction is only a “last ditch” alternative for plants when sexual reproduction fails.

d- Sexual reproduction is only a “last ditch” alternative by which plants can “escape” the condition of being poorly adapted to the local environment.

3. A strawberry farmer's crop has been devastated by a fungal infection. The farmer searches for any fungi-resistant strawberry plants in his fields, but finds none. Why?

a- Due to vegetative reproduction, his plants are genetically diverse.

b- Due to vegetative reproduction, his plants are not genetically diverse.

c- Due to sexual reproduction, his plants are not genetically diverse.

d- Due to sexual reproduction, his plants are genetically diverse.

Answer 1

classmate Date Page O for being dispersed by wind the pollen should be small. Small and light- Joallen will be more prone to wind didversal. ] Lange pollen will have fewer chances of wind dispersal while odour and color are not important for wind pollination Odour and color might be a factor in bollination by birds or insects. Coption d Camcanner correct) Carredoit

in this case neration a correct in this olotion a and b are a If a gener is adapted to local environment the process of vegetative propagation is beneficial because the generation is surviving well so variations are not required but this will eventually lead to local colanization C in absence of varication). Sexual reproduction will bring about- many variations so it is possible - ( that those variations migne- be advantageous in distant and divense environments so sexual reproduction I products can be dispersed. ② option ② is correct. As the farmer fails to find a fungi resistant plant- it means there is no variation in 1 the crop and vegetative propagation gives rises to clones or genetically edentical plants hence all blants are susceptible to fungi. If there would have been sexual reforoduction , the possibility of variation would have increcesed and he could have found csomaner resistant plants. W-scanned with
