What is the relation between the diameter of the teak tree to the annual rings formed?
There is a direct relationship between the diameter of a teak tree and the number of annual rings formed. As the tree grows older, more annual rings are added and the stem diameter increases gradually. These rings are produced by lateral meristematic activity. Therefore, counting annual rings helpsRead more
There is a direct relationship between the diameter of a teak tree and the number of annual rings formed. As the tree grows older, more annual rings are added and the stem diameter increases gradually. These rings are produced by lateral meristematic activity. Therefore, counting annual rings helps estimate both the age and growth pattern of the tree.

If stomata were absent, plants would face serious problems in gaseous exchange and transpiration. Carbon dioxide could not enter properly for photosynthesis and oxygen release would decrease. Transpiration pull responsible for upward water movement would also reduce. Plants would overheat, transportRead more
If stomata were absent, plants would face serious problems in gaseous exchange and transpiration. Carbon dioxide could not enter properly for photosynthesis and oxygen release would decrease. Transpiration pull responsible for upward water movement would also reduce. Plants would overheat, transport less water and minerals and fail to perform important life processes efficiently for healthy growth.

Nervous tissue helps us sense heat, cold, pain and touch. It contains specialised cells called neurons that receive signals from sensory receptors present in the skin. These neurons transmit messages to the brain and spinal cord for interpretation. The nervous system then coordinates suitable responRead more
Nervous tissue helps us sense heat, cold, pain and touch. It contains specialised cells called neurons that receive signals from sensory receptors present in the skin. These neurons transmit messages to the brain and spinal cord for interpretation. The nervous system then coordinates suitable responses, helping the body react quickly to environmental changes and maintain safety.

The simple squamous epithelial tissue lining the alveoli of lungs allows oxygen to enter the blood. These cells are thin and flat, reducing the distance for diffusion. This structure enables rapid exchange of oxygen and carbon dioxide between the air inside lungs and blood flowing through nearby capRead more
The simple squamous epithelial tissue lining the alveoli of lungs allows oxygen to enter the blood. These cells are thin and flat, reducing the distance for diffusion. This structure enables rapid exchange of oxygen and carbon dioxide between the air inside lungs and blood flowing through nearby capillaries, supporting efficient respiration and energy production in the body.

Connective tissue holds different body parts together and provides support and stability. It connects skin, muscles, bones and organs through structures like tendons, ligaments and other supporting tissues. This tissue contains cells embedded in a matrix that provides strength and flexibility. WithoRead more
Connective tissue holds different body parts together and provides support and stability. It connects skin, muscles, bones and organs through structures like tendons, ligaments and other supporting tissues. This tissue contains cells embedded in a matrix that provides strength and flexibility. Without connective tissue, body structures would not remain properly attached and organised.
