... equal to the osmotic force (the cell is turgid) and this is important in the support of leaves and also in the stems of herbaceous plants. In animals like the earthworm support is often provided by the pressure of the fluid inside them, e.g. a hydrostatic skeleton, similarly it is the pressure of the blood in the penis that makes it erect. Water ... ...
... equal to the osmotic force (the cell is turgid) and this is important in the support of leaves and also in the stems of herbaceous plants. In animals like the earthworm the pressure of the fluid inside them, e.g. a hydrostatic skeleton, provides support. Water can also be used to provide a habitat. Life originally evolved in an aqueous habitat and still provides an ... ...
... are found in this class. In this class some have chlorophyll, which allows them to produce their own food others, are pathogenic to man. These organisms use long thread like appendages called flagella to move. The fourth and final class of protazoa is the Sporazoa. The Monocystis, Nosema bombycis and Prospora gigantea belong to this class of protazoa. These organisms are ... ...
... organisms in different deserts of the world. Many diurnal ectotherms are pale to reflect sunlight and avoid overheating. Adaptations to lose heat include high surface-to-volume ratios and long appendages (ears, legs). Some aquatic invertebrates persist in the same way as do annual plants, with dormant stages in their life history that are stimulated to develop by occasional sufficient rainfall ... ...
... have been shown to posses the genes necessary to synthesize photosynthetic organelles (Haberhausen Et Al. 1992). A few dodders have been found to contain low numbers of chloroplast in leaf-like appendages, but all dodders rely fully on their host plants for nutrient absorption. Recent studies involving the Nicotiana tabacum and the dodder Cuscuta reflexa have shown that not only are water ... ...
... , stems, and leaves. Their spore cases are formed on the leaves. Their tissues then simplify. Moss gametophytes are described as "leafy" because they have stemlike structures that bear many leaflike appendages. These are not true stems and leaves because they lack lignin-coated vascular cells. Moss "leaves" are usually only one cell thick and often lack a cuticle, features that enhance water ... ...
