vascular plants with spores

Tracheophytes (Vascular plants) - Tracheophytes include the true land plants or vascular plants. The adult plant body is a sporophyte and shows definite root, stem and leaves. Vascular tissues xylem and phloem are present for the..

Tracheophytes include the true land plants or vascular plants. The adult plant body is a sporophyte and shows definite root, stem and leaves. Vascular tissues xylem and phloem are present for the translocation of water and food respectively. G..

They are found irregularly scattered in the ground tissue. Towards the periphery, the bundles are smaller in size while towards the centre, they are larger in size. The smaller bundles are younger, while the larger ones are older. Hence, the arrangement is described as centrifugal. Each vascu..

Transport in Plants - As mentioned earlier, the transport in higher plants is with the help of the vascular system. Thus, these plants are also called the vascular plants..

A section taken through any region of a typical plant body shows the presence of three tissue systems, namely Epidermal tissue system Ground tissue system and Vascular tissue syst..

1. Mildew Pathogen seen as a growth on the surface of the host. 2. Rust Small pustules of spores, usually breaking through the hoot epidermis. 3. Smuts Pustules larger than those of the rusts. 4. Scab Roughed appearance of the diseased organ. 5. Colour change Change of colour from the no..

Characteristics of Growth in Plants - Growth in plants occurs by cell division and cell enlargement, followed by cell differentiation. Growth in plants is generally limited to regions of growing points known as meristems . The two important growing points present in th..

The plant body is not differentiated into stem, root and leaves but is in the form of an undivided thallus. Vascular tissues are absent. The reproductive organs are single-celled and there is no embryo formation after fertilization. This division includes three sub-divi..

The process of separation of leaves, flowers and fruits from a plant is called abscission. When these parts are removed, the plant seals off its vascular system to prevent loss of water and nutrients and excludes bacteria, fungal spores and other pathogens. A..
