Which of the following is not related to the chromosomal theory of inheritance?

Options:
A Chromosomes as well as genes occur in pairs.
B Behaviour of chromosomes is parallel to the behaviour of genes.
C The two alleles of a genes pair are located on homologous sites on homologous chromosomes.
D Pairing and separation of a pair of chromosomes would lead to the segregation of a factor they carried.

The correct answer is:
Pairing and separation of a pair of chromosomes would lead to the segregation of a factor they carried.

Solution:
Sutton and Boveri argued that the pairing and separation of a pair of chromosomes would lead to the segregation of a pair of factors they carried. Sutton united the knowledge of chromosomal segregation with Mendelian principles and called it the chromosomal theory of inheritance. By 1902, the chromosome movement during meiosis had been worked out. Walter Sutton and Theodore Boveri noted that the behaviour of chromosomes was parallel to the behaviour of genes, and they used chromosome movement to explain Mendel's laws. The important things to remember are that chromosomes, as well as genes, occur in pairs. The two alleles of a gene pair are located on homologous sites on homologous chromosomes.

Which of the following is not related to the non-cyclic process of light reaction?

Options:
A The process involves both the photosystems which are interconnected by the ETS.
B It results only in the synthesis of ATP, but not of NADPH + H+.
C The membranes of the stroma lamellae lacked PS II.
D Photolysis of water is essential for it.

The correct answer is:
It results only in the synthesis of ATP, but not of NADPH + H+.

Solution:
Photosynthesis consists of 2 steps :

1. Light reactions	It is concerned with trapping the light energy for the synthesis of ATP and NADPH.	Membranous system consisting of grana and stroma lamellae in chloroplast.

2. Dark reactions (Doesnât mean that they occur in darkness or that they are not light- dependent).	Utilization of products of light reactions by the enzymatic reactions alongwith CO2 to synthesise the sugar which in turn forms starch.	Stroma in chloroplast.

Non cyclic process involves both PSI and PSII and both are present in Granal lamellae, but stromal lamella contains only PSI. From light reaction total 18 ATP and 12 NADPH2 is formed.
The excited electron does not pass on to NADP+ but is
cycled back to the PS I complex through the electron transport chain.

Which of the following is not related with transpiration pull theory?

Options:
A Capillarity theory
B Ascent of sap
C Cohesive force
D Adhesive force

The correct answer is:
Capillarity theory

Solution:
A number of theories have been put forward to explain ascent of sap. Transpiration pull (cohesion) theory is most widely accepted theory. This theory is most widely accepted theory. This theory is based on cohesive force, adhesive force and transpiration pull.
Capillarity theory describes the xylem vessels to behave like the capillary tubes. This capillarity of the vessels and the normal atmospheric pressure are responsible for the ascent of sap. Due to the surface tension of liquid molecules and adhesive forces, the liquid rises up. The finer the tube, the greater will be the rise of water in it. It is associated with water translocation in xylem vessels.

Which of the following is not the feature of cardiac muscle?

Options:
A Communication junctions are intervertebral disc
B They show branching pattern
C Stimulation received by one cell is passed to neighbouring cells
D They are striated in nature

The correct answer is:
Communication junctions are intervertebral disc

Solution:
Cardiac muscle tissue is a contractile tissue present only in the heart. Cell junctions fuse the plasma membranes of cardiac muscle cells and make them stick together. Communication junctions (intercalated discs) at some fusion points allow the cells to contract as a unit, i.e., when one cell receives a signal to contract, its neighbours are also stimulated to contract. Many cardiac muscle cells assemble in a branching pattern to form a cardiac muscle. Based on appearance, cardiac muscles are striated. They are involuntary in nature as the nervous system does not control their activities directly.

Which of the following is not the function of auxins?

Options:
A Cell elongation
B Fruit ripening
C Cell division
D Inhibit the root growth

The correct answer is:
Fruit ripening

Solution:
Auxins help to initiate rooting in stem cuttings, an application widely used for plant propagation. Auxins promote flowering e.g. in pineapples. They help to prevent fruit and leaf drop at early stages but promote the abscission of older mature leaves and fruits. In most higher plants, the growing apical bud inhibits the growth of the lateral (axillary) buds, a phenomenon called apical dominance. Auxins also induce parthenocarpy, e.g., in tomatoes. They are widely used as herbicides. 2, 4-D, widely used to kill dicotyledonous weeds, does not affect mature monocotyledonous plants. It is used to prepare weed-free lawns by gardeners. Auxin also controls xylem differentiation and helps in cell division.
Ethylene is responsible for the ripening of fruits.
