Ethylene is a gaseous plant growth regulator that acts as both promoter as well as inhibitor. Abscisic acid is a plant growth regulator that is also called the stress hormone as it increases tolerance in plants towards different kinds of stress conditions.

The pH of plant tissue culture media is an important factor affecting nutrient availability and the growth of cultures [1,2]. While many plant species in tissue culture can tolerate a wide range of pH values in the range 4.0–7.2, the best growth results are normally obtained with a slightly acidic media, typically around pH 5.8 .

This unequal growth of the two sides, results in the growth of the stem towards the light. If lit from above, the plant will grow upwards. Typical results by oat seedlings grown in a box with a.

Name the plant hormones responsible for the following: (i) Growth of stem (ii) Promotion of cell division (iii) Inhibition of growth Q. Name the hormone that regulates cell elongation. View More Explore more Characteristics of Auxin

Learning Objectives Describe the difference between meristematic and non-meristematic tissues. Compare and contrast dermal, ground, and vascular tissue. Plants are multicellular eukaryotes with tissue systems made of various cell types that carry out specific functions.

What is the difference between the manner in which movement takes place in a sensitive plant and the movement in our legs?

Plant hormones and growth regulators are chemicals that affect: Flowering. Aging. Root growth. Distortion and killing of organs. Prevention or promotion of stem elongation. Color enhancement of fruit. Prevention of leafing, leaf fall or both. Many other conditions. Very small concentrations of these substances produce major growth changes.

There are five groups of plant-growth-regulating compounds: auxin, gibberellin (GA), cytokinin, ethylene, and abscisic acid (ABA). For the most part, each group contains both naturally occurring hormones and synthetic substances. Auxin Auxin causes several responses in plants: Bending toward a light source ( phototropism ).

different plant cells have different roles many types (parenchyma, collenchyma, sclerenchyma) What are the parts? What’s the difference? or no vacuole chloroplasts large vacuole rectangluar shape cell wall Compare and Contrast Plant cell wall large vacuole chloroplasts flagella only in gametes Both Animal mitochondrion

The primary distinction between animal and plant cells is that animal cells cannot produce their own nutrition. The nucleus, cell membrane, and cytoplasm are the three primary components of most animal cells.

Now when we think about the extracellular matrix for a plant cell, we also think about, there's some other components that are involved in the actual cell wall, and so the cell wall is a key difference between plant and animal cells. So, the cell wall is going to be in a plant cell. Animal cells don't have cell walls.

Vocabulary Scientists divide the Earth’s land into what are called vegetation regions. These areas have distinct types of plants, soil, and weather patterns. Vegetation regions can be divided into five major types: forest, grassland, tundra, desert, and ice sheet.
