Match the column: A B Geotropism Chemicals Chemotropism Touch Thigmotropism Water Hydrotropism Gravity

Tropic movement is exhibited in plants in response to the stimulus present in the environment. Different types of tropic movements are phototropism, geotropism, chemotropism, hydrotropism, thigmotropism, etc. Geotropism: It is the movement induced by the stimulus of gravity. Chemotropism: It is the movement induced due to chemicals. Thigmotropism: It is the movement induced by the stimulus of touch. Hydrotropism: It is the movement induced by the stimulus of water. Hence, the correct match is: A B Geotropism Gravity Chemotropism Chemicals Thigmotropism Touch Hydrotropism Water

Match the following. A B Taxism Growth Nutation Intensity of stimulus Tropism Locomotion Natism Direction of stimulus

Taxism or tactic movement is the movement of locomotion that occurs in response to a stimulus like light, temperature, chemicals, etc. Nutation is the bending movement of the different parts of the plant like leaves, stems, roots, etc due to growth. Tropic movement is exhibited in plants in response to the unidirectional stimulus that is present in the environment and results in positioning in the direction of the stimulus. Nastic movement is the movement in plants that is induced by the intensity of the stimulus. Hence, the correct match is- A B Taxism Locomotion Nutation Growth Tropism Direction of stimulus Natism Intensity of stimulus

Match the following: A B Volvox Circumnutation Desmodium Chemonastism Drosera Movement of variation Pea Phototaxism

The plant exhibits different type of movement in the presence or absence of stimuli. The stimuli may include water, light, gravity, etc. Circumnutation: It is the circular movement that is exhibited by the tips of the growing plant. E.g. Tendrils of pea plant. Volvox contains flagella that help in movement inside the water. E.g. Volvox shows phototaxism. Desmodium shows the movement of variation due to osmotic pressure. Dorsera is an insectivorous plant that shows chemonasty by using mucilage for trapping insects. Hence, the correct match is: A B Volvox Phototaxism Desmodium Movement of variation Dorsera Chemonastism Pea Circumnutation
