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...

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...

green, often delicately-cut leaf tissue. The sori are borne submarginally, and are covered by reflexed flaps of leaf tissue which resemble indusia. Dimorphism...

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...

that water entering the living cells of the roots is forced into the woody tissues or non-living elements through which it passes upward to the leaves at a...

been found to be generally favorable to the accumulation of sugar in the tissues. Observation indicates that after a season favorable for growth, a cold...

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....

of a T or an inverted T, raising the bark with care so that the delicate tissues lying under it will not be injured, and inserting the bud with as little...

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...

of occasional individuals, are inhabited by fungi which live within the tissues either symbiotically or at least without causing any apparent injury to...

mosses require moisture to survive because of the small size and thinness of tissues, lack of cuticle (waxy covering to prevent water loss), and the need for...

wherever sunlight has fallen. This above-ground part develops from stem tissue, but is fused with the root. The interior flesh is entirely white. The entire...

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...

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...

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

attacks the plant just beneath the surface of the ground, causing the softer tissues at this point to rot off and the plant to die. The fungus is not able to...

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