6 Most VSAQ’s of Coordination Chapter in Class 10th Biology (TS/AP)

2 Marks

VSAQ-1 : Write any two tropical movements in the plants.

The two tropic movements in plants are:

  1. Phototropism:
    This is the movement of a plant in response to light, causing it to grow towards or away from the light source.
  2. Geotropism (also known as gravitropism):
    This is the movement of a plant in response to gravity, causing roots to grow downwards and shoots to grow upwards.

VSAQ-2 : What may happen if anger persists for a longer period?

  1. Health and Personal Consequences of Persistent Anger:
    If anger persists for a longer period, it may result in a variety of health and personal issues.
  2. Cardiovascular and Immune System Impact:
    Prolonged anger can lead to cardiovascular issues, such as increased risk of heart disease, and immune system suppression, making the body more susceptible to illnesses.
  3. Mental Health and Relationship Challenges:
    It can also cause mental health problems, including stress and depression, and create strain in relationships.
  4. Additional Health Effects:
    Additionally, chronic anger can lead to digestive problems, sleep disturbances, and a general decreased quality of life.
  5. Importance of Anger Management:
    Therefore, effectively managing anger is crucial for maintaining overall well-being.

VSAQ-3 : Name the part of the brain that maintains the equilibrium.

The cerebellum is the part of the brain responsible for maintaining balance and equilibrium. It plays a crucial role in coordinating movement, posture, and balance, helping us stay steady and maintain our body’s position.

VSAQ-4 : Identify the given part in the diagram and write the use.

  1. The Synapse:
    The identified part in the diagram is a synapse.
  2. Role of the Synapse:
    The synapse is crucial for transmitting information from one neuron to another.
  3. Signal Transformation:
    It acts as a specialized junction where the electrical signal (action potential) in the presynaptic neuron is transformed into a chemical signal (neurotransmitter).
  4. Facilitating Communication:
    This chemical signal then crosses the synaptic gap to activate the postsynaptic neuron, facilitating communication between nerve cells.

VSAQ-5 : A plant which grows near a window bends towards sunlight. Write the reason for it.

  1. Phototropism in Plants:
    The bending of a plant towards sunlight near a window is attributed to phototropism, a plant’s natural response to light.
  2. Role of Auxin:
    The plant hormone auxin plays a key role in this movement.
  3. Auxin’s Effect on Cell Elongation:
    Auxin accumulates on the shaded side of the stem, promoting cell elongation and growth on that side.
  4. Maximizing Sunlight Exposure:
    Consequently, the plant bends towards the light source, enabling it to maximize its exposure to sunlight, which is essential for photosynthesis.

VSAQ-6 : Write the name of the nerve given in the following diagram and write its function.

  1. The Nerve in the Diagram:
    The nerve shown in the diagram is a sensory neuron or afferent nerve.
  2. Function of Sensory Neuron:
    This type of neuron detects stimuli from the surrounding environment, such as touch, temperature, pain, or light.
  3. Information Transmission:
    It is responsible for sending messages from the muscles and sense organs to the central nervous system (brain or spinal cord), enabling the brain to receive information about the external environment and respond accordingly.
