Identify three structures which provide support and protection in a The rest of the questions are answered as well: Experiment 1: Cell Structure and Function. They are broadly classified into prokaryotes and eukaryotes depending on whether are not they contain a membrane-bound nucleus. Erythrocytes red blood cells or RBCs are biconcave cells, filled with hemoglobin, that transport oxygen and carbon dioxide between the lungs and tissues.

Plant Anatomy pp Cite as. The cells of plants possess a variety of included structures; some of which are similar to eukaryotic animal cells, but others are quite distinctive. Many can be observed with a compound light microscope, but others are only resolved with the aid of electron microscopy. One of the great biological achievements of the recent twentieth century has been the development of electron microscopes, the appropriate specimen preparation for observations, and the determination of the structural, genetic, physiological and the elucidation of the role of microscopic and ultrastructural components. This chapter will describe the structure and function of cellular organelles and their respective roles in plant anatomy.

Plant cells are eukaryotic cells present in green plants , photosynthetic eukaryotes of the kingdom Plantae. Their distinctive features include primary cell walls containing cellulose, hemicelluloses and pectin, the presence of plastids with the capability to perform photosynthesis and store starch, a large vacuole that regulates turgor pressure, the absence of flagella or centrioles , except in the gametes, and a unique method of cell division involving the formation of a cell plate or phragmoplast that separates the new daughter cells. Plant cells differentiate from undifferentiated meristematic cells analogous to the stem cells of animals to form the major classes of cells and tissues of roots , stems , leaves , flowers , and reproductive structures, each of which may be composed of several cell types. Parenchyma cells are living cells that have functions ranging from storage and support to photosynthesis mesophyll cells and phloem loading transfer cells. Apart from the xylem and phloem in their vascular bundles, leaves are composed mainly of parenchyma cells. Some parenchyma cells, as in the epidermis, are specialized for light penetration and focusing or regulation of gas exchange , but others are among the least specialized cells in plant tissue, and may remain totipotent , capable of dividing to produce new populations of undifferentiated cells, throughout their lives.
