Question

which of the following occurs during artificial cross-pollination? the scientist completely controls the transfer of pollen from one flower to the stigma of another. the plants reproduce sexually by self-pollination. a different species of plant is crossed with the original.

Explanation:

• For the first option: Artificial cross - pollination is a process where humans (scientists) intervene to transfer pollen from the anther of one flower to the stigma of another flower, and they have full control over this transfer process.
• For the second option: Self - pollination is when pollen is transferred within the same flower or between flowers of the same plant. Artificial cross - pollination is about cross - pollination (between different plants), not self - pollination.
• For the third option: In artificial cross - pollination, usually plants of the same species (or closely related) are crossed. Crossing different species is not the norm in typical artificial cross - pollination for plant breeding or study purposes as it may not result in viable offspring or the desired traits in a predictable way.

Answer:

The scientist completely controls the transfer of pollen from one flower to the stigma of another.
