Important Questions for NCERT Class 11 Biology Plant Growth and Development

Short Answer Type Questions

Question. List five main groups of natural, plant growth regulators. Write a note on discovery, physiological functions and agricultural/ horticultural applications of any one of them. 

Answer. Five main groups of natural, plant growth regulators are auxins, gibberellins, ethylene, cytokinins and ABA. Auxins
(i) Discovery – Auxins was first isolated from human urine. They are generally produced by the growing apices of the stems and roots. Auxins like IAA and IBA have been isolated from plants. NAA (Naphthalene Acetic acid) and 2, 4-D (2, 4-dichlorophenoxyacetic) are synthetic auxins.
(ii) Physiological functions – They help to initiate rooting in stem cuttings, an application widely used for plant propagation. Auxins promote flowering, i.e., in pineapples. They help to prevent fruit and leaf drop at early stages but promote the abscission of older mature leaves and fruits. (iii) Agricultural/horticultural applications – Auxins also induce parthenocary, e.g., in tomatoes. They are widely used herbicides 2, 4-D, and are used to kill dicotyledonous seeds. They do not effect mature monocotyledonous plants, instead is used to prepare seed-free lawns by gardeners. It also controls xylem different and helps in cell division.

Question. The role of ethylene and abscisic acid is both positive and negative. Justify the statement.

Answer. The role of ethylene and abscisic acid is both positive and negative. Ethylene is a simple gaseous PGR. As a negative effect, it is synthesised in large amount by tissues undergoing senescence and ripening. It also promotes senescence and abscission of plant organs expecially of leaves and flowers. As a positive effects, ethylene breaks seed and bud dormancy, initiates germination in peanut seeds, sprouting of potato tubers. It promotes internode/petiole elongation in deep water rice plants. It helps leaves/inner parts of the shoot to remain above water.

Question. How are gibberellins useful in agriculture to improve productivity. Give any three points in support of your answer.

Answer. Gibberellins are useful in agriculture in the following ways
(i) Application of gibberellins increase the length of the stem and increase the yield of sugar in sugarcane.
(ii) Gibberellins delay senescence and the fruits can be left on the trees for longer duration, so as to increase the market period.
(iii) It can cause fruit like apple to elongate and improve in shape.

Question. Name the categories of plant hormones concerned with each of the following and describe one other function of each of the three categories of plant hormones
(i) Inhibition of seed germination
(ii) Promote flowering
(iii) Cell division-promoting activity.

Answer. (i) Abscisic acid, signals closure of stomata to prevent water loss during water stress.
(ii) Auxins, controls cell division and xylem differentiation.
(iii) Cytokinin, helps in the growth of lateral buds and overcome apical dominance.

Question. Mention one antagonistic function for each of the given pair of hormones.
(a) Gibberellin - Auxin
(b) Cytokinin - Abcisic acid
(c) Auxin - Cytokinin

Answer. (a) Gibberellin induces formation of male flowers (masculinity) while auxin induces production of female flowers (feminism) in plants.
(b) Cytokinins prevent senescence and induces stomatal opening but abscisic acid induces senescence and brings about closure of stomata.
(c) Auxin causes apical dominance while it is overcome by cytokinin.

Question. Name a plant hormone that can never act alone. List any three activities of this hormone in conjunction with auxins.

Answer. Cytokinins can never act alone. The three activities of cytokinins in conjunction with auxins :
(a) Morphogenesis : Both auxin and cytokinin should be proportionate in order to allow shoot and root development. If both these PGRS are present in roughly equal concentrations, callus or undifferentiated tissue will be formed. If auxin is higher than cytokinin, then roots will form while if cytokinin is higher than auxin, shoots will form. Thus, auxin and cytokinin have antagonistic effects. This phenomenon is called morphogenesis and is applied to produce a large number of plants by a technique called micropropagation.
(b) Apical dominance : Cytokinins have also known to antagonize auxins in apical dominance. It has been found that if the internal levels of cytokinins in the plant body are high, they promote growth of axillary buds, thereby reducing or overcoming apical dominance.
(c) Cell division : Cytokinins have a direct role in regulating progression through the cell cycle and promote cell division in tissue culture provided auxins are present. Cell division in callus also requires both the hormones.

Question. What would be expected to happen if :
(a) GA3 is applied to rice seedlings
(b) dividing cells stop differentiating
(c) a rotten fruit gets mixed with unripe fruits
(d) you forget to add cytokinin to the culture medium.

Answer. (a) The coleoptile will elongate rapidly, as GA3 helps in cell growth.
(b) The development of callus (mass of undifferentiated cells) will take place.
(c) The unripe fruits will ripe quickly because of the increased rate of respiration due to emission of ethylene from rotten fruit. (d) Cell division will retard and shoot will not initiate from the callus.

Question. What is bolting? How can it be artificially induced?

Answer. It is a process of rapid stem elongation, generally in rosette plants and usually precedes flowering. In general, environmental factors such as photoperiod and/or low temperature trigger bolting in these plants. Exogenous application of gibberellins has been found to induce bolting and flowering in these plants in the absence of required environmental conditions.

 Long Answer Type Questions

Question. Which hormone prevents senescence? Write its different functions and uses.

Answer. Cytokinins cause delay in senescence of intact plant parts. The various functions of cytokinins are as follows :
(i) They promote cell division in tissue culture provide auxins are present. They have a direct role in regulating progression through the cell cycle. Both auxin and cytokinin should be proportionate in order to allow shoot and root development.
(ii) If the internal leaves or cytokinins in the plant body are high, they promote growth of axillary buds, thereby reducing or over coming apical dominance. If cytokinins are applied to axillary buds, lateral shoot growth is promoted.
(iii) They also aid in formation of new leaves, chloroplast development, formation of lateral and adventitious shoots, etc.
(iv) Cytokinins have been found to cause a delay in sentence in mature leaves probably by directing nutrient mobilization and retention by stimulating metabolic activities.
(v) They promote femaleness in plants like auxins and ethylene and help in induction of parthenocarpy. Uses of cytokinins :
(i) In tissue culture, to form new plant varieties by morphogenesis.
(ii) To prolong the shelf-lives of vegetables such as cabbage, lettuce, etc.
(iii) Keep cut flowers fresh.
(iv) To help the plant develop resistance to certain pathogens and extreme temperature variations.

Question. What are plant growth regulators? Name any for different chemical nature of them with one example of each.

Answer. Plant growth regulators are small, simple molecules secreted in minute quantities, that influence various physiological functions in plants. They are of diverse chemical composition. (i) Indole compounds [such as-indole-3-acetic acid (IAA)]
(ii) Adenine derivatives [such as kinetin, 6-furfuryl amino purnie]
(iii) Derivatives of carotenoids [such as abscisic acid (ABA)]
(iv) Terpenes [such as gibberellic acids]

Question. Plant Growth Substances have practical applications. Name the PGS we should use

a) To increase yield of sugarcane.

b) Promote the lateral shoot growth

c) Cause sprouting of potato tuber

d) Inhibit seed germination

Answer. a) Spraying gibberellins
b) Application of auxins
c) Ethylene
d) ABA

Question. Can you alter the rate of growth in an organism? If yes how?

Answer.  Yes, we can alter the rate of growth by making variations in the factors affecting growth, these are light and temperature. A plant grows quicker during the night then during the day. During the night retarding or inhibiting action of light is absent and rate of growth of a plant gradually increases until dawn while during the day the rate of growth gradually decreases until about sunset.

Question. What is "Bioassay"?

Answer. It is evaluation of the effect of a substance on a living organism under controlled conditions. Two bioassays used to examine auxin activity in plants are:
1. The Avena Curvature Test
2. Root growth inhibition test.
