Answer:
The correct answer would be a. Transport of water and minerals from the roots to the shoot system.
The xylem is a type of transporting tissue present in the vascular plants.
It forms the continuous conducting channels which reach all parts of the plants.
The main function of the xylem is to transport water and soluble nutrients unidirectionally to the stem and leaves from roots.
Transpiration pull helps in this passive transport of water from roots to the leaves.
Answer:
Salicylic acid
Explanation:
Salicylic acid is a plant hormone that is essential for a variety of biological parameters, including defence for a plant. There have been many advances in SA-mediated biosynthesis, transport, perception, and signaling over the past two decades. These data show that AS is crucial in local and systemic defensive responses. One such SA-dependent response is systemic acquired resistance (SAR). is a long-distance communication system that provides broad spectrum and long-term resistance to secondary infections throughout the plant. Because of this distinctive property, SAR is a highly sought after trait in agricultural production.This article describes recent developments of the SA function in SAR and analyzes how it connects to other SAR inductors.
A. nucleus
B. cytoplasm
C. mitochondria
D. cell membrane
Answer:
Plant cell bc I did this in school and got it right
A.nucleus
B.vacuole
C.ribosome
D.mitochondrion
Correct answer: B) Vacuole
Vacuoles are the membrane bound structure found in the plant including algae and in some fungi that function to provide structural support and also serve as a site for storage, and waste disposal for the plant.
They do not have a fixed size or shape, plant cell can changed them according to their need.
It tend to be the largest organelle of the plant cell. It also function to maintain the internal pressure required withing the plant cell to provide structure and support to the growing part of the plant.
tools to avoid rusting?
To prevent kitchen tools made from iron from rusting, one can paint them, use stainless steel alloys, or store them in a way that prevents contact with air and water.
To help preserve kitchen tools from rusting, there are few precautions that you can take. The first method is painting iron tools. Water and oxygen come into touch with iron and cause rust, but a coat of paint can stop this from happening. The iron is immune to rust as long as the paint is still on it.
Another strategy is alloying the iron with other metals to form, for example, stainless steel, an iron alloy containing a small amount of chromium. Chromium tends to collect near the surface, where it erodes and forms a passivating oxide layer that protects the iron from rusting.
Lastly, storing your iron kitchen tools under kerosene or mineral oil or in sealed containers could prevent rust by limiting their contact with air and water.
