What is a simple definition of organ?

In biology, an organ (from the Latin “organum” meaning an instrument or tool) is a collection of tissues that structurally form a functional unit specialized to perform a particular function. Your heart, kidneys, and lungs are examples of organs.

What are the plant organs and their functions?

The three organs of vascular plants, roots, stems and leaves, reflect the basic biology of terrestrial autotrophs: leaves acquire sunlight and carry out photosynthesis to ‘feed’ the organism, roots explore the soil and acquire the water and nutrients that is required for photosynthesis and growth, and stems connect the …

What is the function of the organ?

The function of an organ system depends on the integrated activity of its organs. For instance, digestive system organs cooperate to process food. The survival of the organism depends on the integrated activity of all the organ systems, often coordinated by the endocrine and nervous systems.

What are the main organs of a plant?

Plant Organ Systems. Vascular plants have two distinct organ systems: a shoot system, and a root system. The shoot system consists stems, leaves, and the reproductive parts of the plant (flowers and fruits). The shoot system generally grows above ground, where it absorbs the light needed for photosynthesis.

Root, stem, leaf and FU are four basic plant organs (Figure 5.2. 3) which in bipolar plant could be grouped in root and shoot system; the latter is frequently split into generative shoot system (bearing FU), and vegetative shoot system (without FU). Figure 5.2. 3 Bipolar plant: organ systems and four organs.

Why leaf is called an organ of the plant?

Answer: An organ is a collection of tissues joined together as a structural unit in order to perform a common function. Leaves are typically found in vascular plants, which have lignified tissues (xylem) that enable them to conduct water.

Plant organs: Leaf, Roots, Stem, Flower.

What are the 3 plant organs?

Each plant organ (roots, stems, leaves) contains all three tissue types: Dermal tissue covers and protects the plant, and controls gas exchange and water absorption (in roots).

Is a leaf an organ?

The leaves are the primary photosynthetic organs of plants, serving as key sites where energy from light is converted into chemical energy. Similar to the other organs of a plant, a leaf is comprised of three basic tissue systems, including the dermal, vascular, and ground tissue systems.
