Textbook Question
Chapter 56.3, Problem 2CS
Core Skill: Connections Look back at Figure 40.21. What is unusual about the reproductive strategy of the mother of thousands plant?
Figure 40.21 Asexual reproduction via somatic embryogenesis. The leaves of this Kalanchoë plant bear small plantlets around the edges. When mature, these plantlets drop off and, under the right conditions, grow into new plants.

Where in the diagram would you add identical to parent A)a B)b C)c D)darrow_forwardwhat are the flaws ? Plants reproduce in a pattern known as alternation of generations. A haploid gametophyte produces gametes through mitosis. The gametes fuse to form a zygote, which then grows into a diploid sporophyte. The sporophyte produces spores through meiosis, which then grow into a gametophyte and start the process over. Flowers are how angiosperms reproduce. A whorl of sepals (corolla) is at the base of the flower, followed by a whorl of petals (calyx). Inside the flower is a female organ known as a carpel and it is made of a stigma, style, and ovary. The male organ is the stamen and it is made of an anther and filament. Pollen being transferred to the style is known as pollination. Once the pollen travels down the style and reaches the egg, fertilization happens when sperm meets egg. Then, the fertilized egg and surrounding tissue develops into a seed. A seed is protected by a seed coat and contains endosperm and an embryo. The endosperm grows into a new plant while…arrow_forward

The gametophyte life cycle, wherein a haploid spore is produced, and the sporophyte life cycle wherein there is union of the gametes. Below are different events in the development of flowering plants. Arrange them in the correct order. Place the number from 1 to 6 inside the box. The hypocotyl pushes to the soil along with the cotyledon(s). It starts as a seed which contain the miniature plant called embryo. Of the two sperm cells, one sperm fertilizes the egg cell, forming a diploid zygote; the other sperm fuses with the two polar nuclei, forming a triploid cell that develops into the endosperm Mature plant develops the gametes, releases the pollen and pollinates the flower. It is the process wherein seeds are transported, spread or moved away from the parent plant either by wind, water, animals or insect. The plant, given enough nutrients will develop in a mature stage.
