Angiosperms use seeds to contain their embryos, unlike ferns.
To determine the answer to your question, "unlike ferns, angiosperms use ______ to contain their embryos," we can break down the options and analyze the characteristics of angiosperms.
1. Seeds: Angiosperms do indeed produce seeds, which are structures that contain the embryonic plant along with a food supply and protective seed coat. The seeds play a crucial role in the reproduction and dispersal of angiosperms.
2. Spores: While spores are involved in the reproductive life cycle of both ferns and angiosperms, they are not directly responsible for containing the embryos in angiosperms. In ferns, spores are released from sporangia and develop into tiny gametophytes. These gametophytes produce the sperm and egg cells that ultimately fertilize to form embryos.
3. Sporangium: Sporangium refers to the structure in which spores are produced. It is present in both ferns and angiosperms. However, it is not the structure that contains the embryos in angiosperms.
4. Pollen: Pollen is a fine powdery substance produced by the male reproductive organ of flowering plants (angiosperms). It contains the male gametes (sperm cells) and serves as the means of transferring them to the female reproductive organ (pistil) for fertilization. While pollen does not directly contain the embryos, it is involved in the fertilization process that leads to embryo formation.
Considering the options provided, the correct answer is "Seeds." Angiosperms use seeds to contain their embryos, which is a distinguishing feature compared to other plants like ferns.

How will auxin influence cell growth in the roots of these plants?
(1 point)
• Auxin will build up on the lower side of the root and stimulate cell growth.
• Auxin will build up on the lower side of the root and inhibit cell growth.
• Auxin will build up on the upper side of the root and inhibit cell growth.
© Auxin will build up on the upper side of the root and stimulate cell growth.
The correct answer is:
• Auxin will build up on the lower side of the root and stimulate cell growth.
