In this section the learners now expand their knowledge and learn the various cell structures and related functions.

Plant Cell

Contributors explore most of the ideas concerning the structure, biochemistry, and function of the nuclei, chloroplasts, mitochondria, vacuoles, and other organelles of plant cells. This book is organized into 13 chapters and begins with an overview of the enzymology of plant cell organelles and the localization of enzymes using cytochemical techniques. The text then discusses the structure of the nuclear envelope, chromosomes, and nucleolus, along with chromosome sequestration and replication. The next chapters focus on the structure and function of the mitochondria of higher plant cells, biogenesis in yeast, carbon pathways, and energy transfer function. The book also considers the chloroplast, the endoplasmic reticulum, the Golgi bodies, and the microtubules. The final chapters discuss protein synthesis in cell organelles; polysomes in plant tissues; and lysosomes and spherosomes in plant cells.

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.

Many plant cell organelles are also found in animal cells. For an overview of animal cells, see the previous tutorial. Part 1 is the cell wall. Cell walls are composed of cellulose, or plant fiber. This polysaccharide provides plant cells with strength and rigidity.

The organelles found only in plant cells include- chloroplast, cell wall, plastids, and a large central vacuole. The chloroplasts contain a green pigment chlorophyll that is responsible for the process of photosynthesis.


Plant Cell Structure and Ultrastructure

Plant cell

Organelles make up the subunits of a cell. There are numerous each with their own function. The plasma membrane is the organelle that encapsulates the contents of the cell. Apart from encapsulating cell contents, the plasma membrane also plays a vital role in regulating the movement of substances in and out of the cell.
