Tropic movement refers to a plant’s directional growth response to an external stimuli. Movement can be either in the direction of the stimulus or away from it. For example, shoots exhibit negative geotropic movement while roots exhibit positive geotropic movement and grow in the direction of gravity.
Column A Column B (a) Olfactory receptors (i) Tongue (b) Thermo receptors (temperature receptors) (ii) Eye (c) Gustatoreceptors (iii) Nose (d) Photoreceptors (iv) Skin ANSWER :- Column A Column B (a) Olfactory receptors (iii) Nose (b) Thermo receptors (temperature receptors) (iv) Skin (c) Gustatoreceptors (i) Tongue (d) Photoreceptors (ii) Eye
ANSWER :- (a)Dendrite(b)Cell body(c) Axon(d)Axon terminal
ANSWER :- Figure( a) is more accurate because in the figure a plant root shows positive geotropism and the shoot shows positive phototropism.
Answer :- (a)Pineal Gland(b)Pituitary gland(c)Thyroid gland(d)Thymus
Answer:- (a) Auxin(b) Gibberellin(c) Cytokinin(d) Abscisic acid
Answer :- (a) Sensory neuron(b) Spinal cord(c) Motor neuron (d) Muscle
(d) nervous and endocrine system The control and regulation of life processes do not include the reproductive, respiratory, or digestive systems. All processes, including those of the reproductive, respiratory, and digestive systems, are regulated and controlled by the nervous and endocrine systems.
(d) synapse A synapse is a structural structure that allows one neuron to transfer an electric signal to an effector cell or following neuron. The junction is therefore between two neurons.
(c) Pituitary There are two adrenal glands, one on top of each kidney. Males have two testes, which are paired glands that produce hormones used in sex. Females have a paired gland called the ovary that makes female sex hormones. A separate gland located below the brain is called the pituitary. Since it secretes the …
