base. Like many other species of Papaver, it exudes a white latex when the tissues are broken. It is known to have been associated with agriculture in the...

environmental elements. Water in the plant tissues may move to the roots to assist in passive absorption. Xylem and phloem tissues are involved in the conduction processes...

Although non-vascular plants lack these particular tissues, a number of non-vascular plants possess tissues specialized for internal transport of water. Nonvascular...

In vascular plants, phloem is the living tissue that carries organic nutrients, particularly sucrose, a sugar, to all parts of the plant where needed....

active layer of tissue,—the phellogen. The bark is developed in different ways on different trees. So distinct are the resulting tissues that species of...

leaf petioles Flax stem cross-section, showing locations of underlying tissues. Ep = epidermis; C = cortex; BF = bast fibres; P = phloem; X = xylem; Pi...

widely separated from the true mildews. The mycelium is parasitic within the tissues of the host, only the fruiting branches appearing at the surface. The fruiting...

khein, to pour. Main article: Ground Tissue: Parenchyma Parenchyma cells are thin-walled cells of the ground tissue that make up the bulk of most nonwoody...

The types of ground tissue found in plants develops from ground tissue meristem and consists of three simple tissues: Parenchyma (have retained their protoplasm)...

chloroplast (chlorenchyma tissue, a type of parenchyma) to light over a broad area, and to allow light to penetrate fully into the tissues. Leaves are also the...

consisted of xylem in the center, surrounded by a region of phloem tissue. Around these tissues there might be an endodermis that regulated the flow of water into...

meristem - a tissue consisting of embryonic (incompletely differentiated) cells from which other (and more differentiated) plant tissues originate. Primary...

meristem is required to provide new cells for expansion and differentiation of tissues and initiation of new organs, providing the basic structure of the plant...

tissue: the vascular cambium and the cork cambium. All the vascular tissues within a particular plant together constitute the vascular tissue system of...

without a shell. Both cause damage simply by eating the leaves and plant tissue with mouths that are under their bodies. They hide during the day, and eat...

more than one type of genetic makeup in their tissues. A lack of chlorophyll producing tissue in some tissues causes variegation with white or yellow coloured...

In many vascular plants, secondary growth is the result of the activity of the vascular cambium. The latter is a meristem that divides to produce secondary...

on tumor cells because the interior pH of tumor tissues is generally lower than that of normal tissues, and betulinic acid is only active at those lower...

plants') that are non-vascular: they have tissues and enclosed reproductive systems, but they lack vascular tissue that circulates liquids. They neither flower...

is one which fastens itself upon another living thing, penetrating the tissues of the host or organism attacked, thus usually deriving some or all of its...
