Anatomical Difference between Dicot (Dorsiventral) Leaf and Monocot (Isobilateral) Leaf – Comparison Table


Difference between Dorsiventral and Isobilateral Leaf

Dicot Leaf vs Monocot Leaf
(Difference between Dorsiventral and Isobilateral Leaf)

Dicot leaves are also called as dorsiventral leaves because they possess distinct dorsal and ventral sides. Monocot leaves are called isobilateral leaves since both the sides of monocot leaves are more or less similar. Dicot and monocot leaves show considerable differences both in their morphological and anatomical characteristics. The present post discusses the Difference between Dicot and Monocot Leaf with a Comparison Table.

Difference between Active and Passive Water Absorption – Comparison Table


Active vs Passive Absorption of Water

Active vs Passive Water Absorption
(Difference between Active and Passive Absorption of Water in Plants)

Plants absorb water along with minerals from the soil through root by a process called ‘absorption of water’. Based on the involvement of metabolic energy, the water absorption process in plants may be of two types – (1) Active absorption and (2) Passive absorption.

Active absorption: It is the absorption of water, usually against the concentration gradient, by the utilization of metabolic energy (energy from ATP).

Passive absorption: Absorption of water without the utilization of metabolic energy.

Difference between Bone and Cartilage – Comparison Table


bone vs cartilage

Bone vs Cartilage
(Similarities and Differences between Bone and Cartilage)

Bone and cartilage are connective tissues which form the skeletal system in the body. Bones are hard and tough which gives the structural framework of the skeleton in the body. Cartilages are soft and flexible components present in ear, nose and joints. Cartilage acts as shock absorbers between two bones and they prevent the rubbing between them the bones. Even though the bones and cartilages are connective tissues and they are the components of the skeletal framework, both show considerable differences in their formation, organization and functions. The present post discusses about the Similarities and Differences between Bone and Cartilage with a Comparison Table.

Similarities between Bone and Cartilage

Ø  Both bone and cartilage are connective tissues.

Ø  Both are the components of the skeletal system.

Ø  Both provide shape to body parts.

Ø  Both provide protection to vital organs.

Ø  Both are mesodermal in origin.

Ø  Both composed of specialized cells embedded in the matrix of fibrous proteins.

Tendons vs Ligaments
(Similarities and Differences between Tendons and Ligaments)

Tendons and Ligaments are connective tissues* belong to the category of ‘Dense Granular Connective Tissues’. They are the essential component for the proper functioning of the skeletal and muscular system.

Tendons: Tendons are cord-like, strong, inelastic structures that join skeletal muscles to bones.

Ligaments: Ligaments are elastic structures which connect bones to bones in joints.
