Plant body

Your kidneys and lungs attempt to maintain a slightly alkaline pH of 7. Diet has a large role in its ability to maintain that beautiful balance of 7. An overly acidic body is known as acidosis, at which point the body can not function properly as it should.

Internal Organization of Vascular Plant 5. Modular Growth of Plant Body. Contents of the Plant Body: The plant body consists of a number of organs, i.

The flower consists of sepals, petals, stamens, carpels and sometimes also sterile members. Each organ is made up of a number of tissues.

Each tissue consists of many cells of one kind. The complex multicellular body of the seed plant is a result of evolutionary specialization of long duration.

This specialization has given rise to the establishment of morphological and physiological differences between the various parts of the plant body and also caused the development of the concept of plant organs. The organization of the plant body of the oldest known land plants, the Psilophytales, suggests that the differentiation of the vegetative plant into leaf, stem and root is a result of evolutionary development from an originally simple axial structure Arnold, ; Eames, As regards the morphologic nature of the flower it is thought that the flower is homologous with a shoot and the floral parts with leaves.

Fundamental Parts of the Plant Body: The axis, consists of two parts—that portion which is normally aerial is known as the stem, and the portion which is subterranean is called the root.

There are three types of appendages arising from the axis: The strands of vascular tissue pass through the leaves. The leaves are characteristic of the stem and do not occur on the root. The leaves are found to be arranged on the stem in a definite manner, and bear an intimate structural relation to the skeleton of the axis.

The leaf is looked upon as the lateral expansion of the stem, continuous with it. All fundamental parts of the stem are concerned with the formation of the leaf.

In the appendages of the second rank only the outermost layers of stem, the cortex and the epidermis, are usually present which are known as emergences.

The prickles of the rose make a good example of it. The appendages of the third rank are hairs.

These are projections of the outermost layer of the cells. The emergences and hairs occur on both axis and leaves, usually without definite arrangement. Development of the Plant Body: A vascular plant begins its existence as a morphologically simple unicellular zygote 2n.

The zygote develops into the embryo and thereafter into the mature sporophyte. The development of the sporophyte involves division and differentiation of cells, and an organization of cells into the tissues and tissue systems.

The embryo of the seed plant possesses relatively a simple structure as compared with the mature sporophyte. The embryo bears a limited number of parts— generally only an axis bearing one or more cotyledons.Plant Body All but a relatively few plants are multicellular, and the majority have bodies composed of two major systems: the root system and the shoot system.

The former is usually underground, and the latter above ground. If you're looking to eat healthier, lose weight, and have more energy throughout the day, researchers advise trying a plant-based or Mediterranean diet.

Hybridization is the process of interbreeding between individuals of different species (interspecific hybridization) or genetically divergent individuals from the same species (intraspecific hybridization).

Main photosynthetic organs through leaves (so leaves are the photosynthetic organs) Holds leaves up in the sunlight with the stem Stem helps connects roots and leaves. Aromatherapy is the practice of using the natural oils extracted from flowers, bark, stems, leaves, roots or other parts of a plant to enhance psychological and physical well-being.
