Biology Quiz On Life Processes! Trivia

1. The autotrophic nutrition requires ________

CO2 and water

Chlorophyll

Sunlight

All the above

Autotrophic nutrition is a process in which organisms produce their own food using inorganic substances like CO2 and water. Chlorophyll, a pigment found in plants, is essential for photosynthesis, the process by which autotrophs convert sunlight into energy. Therefore, autotrophic nutrition requires all the mentioned components - CO2, water, chlorophyll, and sunlight - for the production of food.

2. The xylem in the plants are responsible for __________

Transport of water

Transport of food

Transport of amino acids

Transport of oxygen

The xylem in plants is responsible for the transport of water. Xylem is a specialized tissue that consists of hollow, tube-like structures called vessels, which allow water to move upwards from the roots to the leaves. This process, known as transpiration, helps to maintain the plant's hydration, provide nutrients to the cells, and support photosynthesis. Water is essential for various metabolic processes in plants, including nutrient uptake, cell expansion, and maintaining turgidity. Therefore, the xylem plays a crucial role in ensuring the efficient transportation of water throughout the plant.

3. The roots of coconut tree are seen away from the plant. Such kind of movement of root for want of water is _______

Phototropism

Geotropism

Chemotropism

Hydrotropism

Hydrotropism is the movement of plant roots in response to water. In this case, the roots of the coconut tree are seen away from the plant because they are actively growing towards areas where water is present. This is a survival mechanism for the plant to ensure that its roots can access water for absorption. Phototropism is the movement of plants in response to light, geotropism is the movement of plants in response to gravity, and chemotropism is the movement of plants in response to chemicals. None of these terms accurately describe the movement of the coconut tree roots in search of water.

4. The product obtained in the Anaerobic respiration of yeast is _______

Lactic acid

Pyruvic acid

Ethanol

Acetic acid

In anaerobic respiration, yeast undergoes fermentation to produce energy without the presence of oxygen. During this process, glucose is converted into ethanol and carbon dioxide. Therefore, the correct answer is ethanol.

5. In monotropa the special type of root which absorbs nourishment is _______

Haustoria

Mycorrhizal root

Mycorrhizal rootClinging rootMycorrhizal rootClinging rootClinging root

Adventitious root

Monotropa is a parasitic plant that lacks chlorophyll and cannot perform photosynthesis. It obtains its nourishment from the roots of other plants through a symbiotic relationship. The special type of root in Monotropa that absorbs nourishment is called mycorrhizal root. This type of root forms a mutualistic association with fungi, allowing the plant to obtain nutrients from the surrounding soil through the fungal hyphae.
