Which of the following is true about pollination in flowers? (1 point)

Question

Animals pollinate flowers when they drink nectar from the base of the filaments which are in between the petals.
• Bees pollinate flowers when pollen gets stuck to their bodies, then is transferred to the stigma.
• Flowers' stigmas hold the ovules and when pollen reaches the stigma, the eggs are fertilized.
Item 1
Item 2
Item 3
Item 4
• Plants can only reproduce sexually, so during pollination the pollen of one flower must be transferred to a second flower.

Answer 1

Let's evaluate each statement regarding pollination in flowers:

1. Animals pollinate flowers when they drink nectar from the base of the filaments which are in between the petals.

   • This statement is incorrect. While animals (such as bees and butterflies) do pollinate flowers when they drink nectar, the filaments (parts of the stamen) do not directly hold nectar; nectar is usually produced in nectaries, which can be located at the base of the flower, but not specifically at the base of the filaments.

2. Bees pollinate flowers when pollen gets stuck to their bodies, then is transferred to the stigma.

   • This statement is true. Bees collect pollen on their bodies as they visit flowers for nectar, and when they move to another flower, they transfer pollen to the stigma of that flower, facilitating pollination.

3. Flowers' stigmas hold the ovules and when pollen reaches the stigma, the eggs are fertilized.

   • This statement is partially incorrect. While the stigma is the part of the flower that receives pollen, the ovules are located in the ovary, which is below the stigma. Fertilization occurs after the pollen germinates on the stigma and the pollen tube grows down to the ovule in the ovary.

4. Plants can only reproduce sexually, so during pollination the pollen of one flower must be transferred to a second flower.

   • This statement is incorrect. While many plants reproduce sexually through pollination between different flowers (cross-pollination), some can also reproduce asexually, and many flowers can self-pollinate (pollination occurs within the same flower).

Based on this evaluation, the only true statement is:

Bees pollinate flowers when pollen gets stuck to their bodies, then is transferred to the stigma.
