Nitrogen, potassium, phosphorus, calcium, magnesium, and sulfur are the major macronutrients required by plants. The micronutrients needed include iron, copper, manganese, magnesium, and others. A deficiency of just one nutrient in plants may result in stunted growth of the plant or poor physiological development during critical stages. Plant.

Indole-3-acetic acid (IAA), the most important auxin in plants, is mainly synthesized from l -tryptophan via indole-3-pyruvate (IPA) by the TAA and YUC families in Arabidopsis. Open in new tab Download slide auxin, biosynthesis, indole-3-acetic acid, TAA, YUCCA Issue Section: Review

The epidermis is usually one cell layer thick. However, in plants that grow in very hot or very cold conditions, the epidermis may be several layers thick to protect against excessive water loss from transpiration. A waxy layer known as the cuticle covers the leaves of all plant species.

Phototropism, or the differential cell elongation exhibited by a plant organ in response to directional blue light, provides the plant with a means to optimize photosynthetic light capture in the aerial portion and water and nutrient acquisition in the roots.

Simple tissue is composed of only one kind of cell, and complex tissue is composed of two or more kinds of cells. Simple Tissues. There are five types of simple tissue: epidermis, parenchyma, collenchyma, sclerenchyma, and cork Epidermis covers the outer surfaces of leaves, young roots, and stems. As plants (especially woody plants) age, the.

Simple tissues are made up of only one type of cells, which look like each other. On the other hand, complex tissues are made up of more than one type of cells. Parenchyma, collenchyma and sclerenchyma are examples of simple plant tissue, whereas xylem and phloem are examples of a complex tissue.

xylem, plant vascular tissue that conveys water and dissolved minerals from the roots to the rest of the plant and also provides physical support. Xylem tissue consists of a variety of specialized, water-conducting cells known as tracheary elements. Together with phloem (tissue that conducts sugars from the leaves to the rest of the plant), xylem is found in all vascular plants, including the.

Interactions among plant hormone signals are at the core of plant responses to biotic and abiotic stress factors. JA does not have an independent regulatory role but works within a complex signal network with other phytohormone signaling pathways, such as those of ABA [ 66 , 67 ], ET [ 68 ], SA [ 69 ], GA [ 70 ], IAA [ 71 ], and BR [ 72 ].

What are the components of the transport system in highly organised plants?AnswerIn plants, there are two conducting tissues which make up the transport system.These areXylemandPhloem.Xylem tissues carry water and minerals.Xylem tissues contain xylemvessels,tracheidsand otherxylem elements.Phloem ti
