To determine: The value of the research on genes that controls seed germination to the society.
Concept introduction: Flower is a reproductive part of a modified thick shoot of an angiosperm plant. The flowering plants generate offspring through a process called reproduction. The reproduction in plants can be sexual or asexual. Sexual reproduction is a bi-parental process (both male and female gametes are involved), whereas asexual reproduction is a uni-parental process (only one parent plant is involved).

- What is the evolutionary advantage for a flowering plant to be pollinated with pollen from a different individual plant (of the same species)?arrow_forwardthe evolutionary advantage of seed, pollen, flowers, and fruit?arrow_forwardHow do plants regulate flowering ?(explain the Molecular mechanism of flowering )arrow_forward
- What preliminary conclusions can you draw from the results of the experiment and what is the independent and dependent variable ?arrow_forwardWhich of the following is not a component of a flower?a. sepalb. stamenc. carpeld. coleoptilearrow_forwardWhich of the following best explains the function of sepals during flower formation? ANSWER CHOICES ARE IN THE PHOTO. thanks.arrow_forward
- Which of the following sequence represents the events that take place in the development of a fruit? -pollination, fertilization, germination of pollen tubes, ovule matures, embryo forms. -pollination, double fertilization, ovule matures, embryo forms within the seed, ovary matures around the seeds. -pollination, fertilization, embryo development within the seed, ovary matures around the seeds. -pollination, germination of pollen, endosperm, ovule. -pollination, endosperm formation, embryo development within the seed, ovule matures.arrow_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_forwardWhat is the most likely consequence of a mutation that would cause sporopollenin to degrade quickly right after it is synthesized? -A reduction in the ability of pollen and spores to survive intact and disperse to new areas. -A reduction in the ability of pollinators to detect and transfer pollen grains to a stigma. -A decrease in the number of sperm that can be produced. -A decrease in the ability of the pollen grain or spore to open when a suitable location is found. -A reduction in the ability of the integument of an ovule to develop into a seed coat.arrow_forward
- Using just the 'ABC model' of floral development what would you need to change in terms of genes or gene expression to get male only flowers, but still have 3 different floral whorls in total? Then what would you need to change to get female flowers and again have three different floral whorls in total?arrow_forwardPlants and animals usually battle each other; describe why and how this occurs. Once animal-pollinated flowers evolved, a new type of plant–animal interaction was possible; describe it. How is it possible for a mutation in aplant to be beneficial for both the plant and for an animal?arrow_forwardUrkle decided he wanted to test the effects of watering his plants with cold coffee. For a week he watered one group of plants cold coffee. He ignored the other group of plants. Urkle has no idea what might happen to plants that receive coffee. What is wrong with Urkle's experimental design? If Urkle wants to test the effects of cold coffee on plant growth, he should water his control group with cold water. If Urkle wants to test the effects of cold coffee on plant growth, he should water the plants in the other group with Dr. Pepper. If Urkle wants to test to test the effects of cold coffee on plant growth, he should water the plants in the other group with hot coffee. If Urkle wants to test the effects of cold coffee on plant growth, he can ignore the control group as long as he makes sure both groups get the same amount of sun.arrow_forward
