Summary Introduction
To determine: The mechanism by which the plants tend to elongate along one axis instead of expanding in all directions.
Introduction: There are several developmental processes in plants that make the cells to organize into complex organisms. The process by which structures originate and mature as a new plant is called plant development. The developmental procedure occurs due to the inherited genetic information of the organism and environmental effects. For example, one genotype could produce various

- What is the wall resistance of plant cells? Does this resistance facilitate or make difficult the entrance of water into the cell?arrow_forwardIn farming communities, there is a concern that over irrigation can leech nutrients out of the soil, flood a farm area, and add salt to the soil in a process called salinization. The overall negative results are that some plants cannot germinate (grow from seed) and other adult or growing plants will die. Explain what is happening on the cell level, in regards to transport across the cell membrane, why seeds might not germinate, and why adult plants might die.arrow_forward(a) Describe the role of mitosis in the growth of a plant.

- Detection of external signals by plant cells often results in a transient rise in the concentration of Ca2+ ions in the cytoplasm. What transport processes can cause such an increase in cytoplasmic Ca2+, and what transport processes can remove the excess Ca2+ and restore the level of Ca2+ to its resting state?arrow_forwardAccording to data from genome sequences, cytoplasmic dynein is absent in some plants (e.g.,Arabidopsis) and present in others (e.g.,rice).Does this finding surprise you? What else might you do to confirm or refute such a statement? How is it possible that higher plant cells could operate without cytoplasmic dynein?arrow_forward(1) A plant cell may burst when : (A) Turgor pressure equalises wall pressure.
