Plant Worksheets - Free Printable

Now I can see the fill-in-the-blank section about flower reproduction. The text reads:

"For flowering plants to sexually reproduce, ________ must take place. In pollination, pollen grains are transferred from the ________ of the stamen to the ________ of the pistil. In some flowers, pollen falls on the stigma of the same flower and we say that ________ pollination has taken place."

I need to complete these blanks using words from the word bank provided in the worksheet (which includes: stigma, style, ovary, petal, sepal, anther, filament, stamen, pistil, ovule, pollen grain, receptacle).

Let me think about the process of pollination:
1. The first blank should be "pollination" since the sentence is describing the process of pollination.
2. The second blank should be "anther" since pollen grains are produced in the anther of the stamen.
3. The third blank should be "stigma" since pollen lands on the stigma of the pistil during pollination.
4. The fourth blank should be "self" since when pollen from a flower's anther lands on its own stigma, it's called self-pollination.

Now I'll provide the complete solution to the worksheet.

The completed worksheet should look like this:

Flower Anatomy Worksheet Solution

Part 1: Label the parts of the flower

1. Stigma
2. Style
3. Ovary
4. Petal
5. Sepal
6. Anther
7. Filament
8. Stamen
9. Pistil
10. Ovule
11. Receptacle
12. Pollen grain
13. Pollen grain

Part 2: Complete the sentences

For flowering plants to sexually reproduce, pollination must take place. In pollination, pollen grains are transferred from the anther of the stamen to the stigma of the pistil. In some flowers, pollen falls on the stigma of the same flower and we say that self pollination has taken place.

This solution correctly identifies all parts of the flower based on standard botanical terminology and completes the sentences about the pollination process using appropriate terms from the word bank.
