example of comparative anatomy

The comparative anatomical studies of various types of organisms shows structural and functional differences and similarities between various species. For example, the basic structure of all the flowers is the same with the whorls of calyx, corolla, androecium and gynoecium. How..

Anatomy which favours the amount of CO 2 diffusion into collenchyma cells the intensity dilution of light and the rate of photosynthesis. Thickness of epidermis, size structure, position and frequency of stomata, distribution of vascular tissue and intercellular spaces, position and num..

Anatomy of the Leaf - Leaf represents an important part of the plant body. It is involved in vital physiological activities such as transpiration, respiration and photosynthesis. Unlike the stem and the root, the leaf is flat and hence, the anatomy of the leaf differs very much ..

Leaf represents an important part of the plant body. It is involved in vital physiological activities such as transpiration, respiration and photosynthesis. Unlike the stem and the root, the leaf is flat and hence, the anatomy of the leaf differs very much from that of stem or root. There..

Epidermis is the outermost covering of the stem. It is represented by a single layer of compactly arranged, barrel-shaped parenchyma cells. Intercellular spaces are absent. The cells are slightly thick walled. Epidermis shows the presence of numerous multicellular projections called trichomes..

Anatomy of a Typical Monocot Root - Example : Maize A transverse section passing through the Maize root reveals the following detail..

Example: Sunflower A transverse section passing through the root of Sunflower reveals the following detail..

Example: Zea mays (Maize) A transverse section passing through the stem of Maize reveals the following detail..

Epiblema is the outermost covering of the root formed by single layer of compactly arranged, barrel-shaped, parenchyma cells. The cells are characteristically thin-walled since they are involved in absorption of water. A cuticle and stomata are absent. Some of the epiblema cells are produced ..

Plant Anatomy - Anatomy of a Typical Young Dicot Stem - Example: Helianthus annus (Sunflower) A transverse section taken through the young stem of Sun-flower reveals the following detail..
