Hey Art — ready when you are. 28) Osmosis is an important process in plants. Justify. Osmosis is the movement of water molecules from a region of higher water potential to a region of lower water potential across a partially permeable membrane. In plants, osmosis is crucial for the absorption of water from the soil by root hair cells, which have a lower water potential than the soil. This water is then transported throughout the plant. Osmosis also maintains turgor pressure within plant cells, which provides structural support, keeps leaves and stems rigid, and is essential for processes like the opening and closing of stomata. Without osmosis, plants would wilt and be unable to carry out vital functions like photosynthesis. 29) A homozygous sweet pea with white flowers was crossed with a homozygous sweet pea with red flowers. All of the offspring had red flowers. a) State which allele of this gene is dominant. Since all offspring from a cross between homozygous white and homozygous red flowers resulted in red flowers, the red flower allele is dominant. b) Two heterozygous sweet pea plants with red flowers were crossed as shown below. Draw a Punnett square to show the genotypes that are produced in this cross. Let R represent the dominant red allele and r represent the recessive white allele. Parental genotypes: Rr × Rr |c|c|c| Gametes & R & r \\ R & RR & Rr \\ r & Rr & rr \\ The genotypes produced are: RR* Rr* rr* The genotypic ratio is 1 RR : 2 Rr : 1 rr. Send me the next one 📸
