About This Book
Plant Cells and Their Organelles provides a comprehensive overview of the structure and function of plant organelles. The text focuses on subcellular organelles while also providing relevant background on plant cells, tissues and organs. Coverage of the latest methods of light and electron microscopy and modern biochemical procedures for the isolation and identification of organelles help to provide a thorough and up-to-date companion text to the field of plant cell and subcellular biology. The book is designed as an advanced text for upper-level undergraduate and graduate students with student-friendly diagrams and clear explanations.

Cells
Parenchyma, chlorenchyma, collenchyma, and sclerenchyma are the four main plant cell types (Figure 1.1, Evert, 2006). Meristematic cells, which occur in shoot and root meristems, are parenchyma cells. Chlorenchyma cells contain chloroplasts and lack the cell wall thickening layers of collenchyma and sclerenchyma. Certain epidermal cells can be specialized as stomata that are important in gas exchange (Bergmann and Sack, 2007). The diverse cell types (Zhang et al., 2001; Yang and Liu, 2007) are shown in Table 1.1. Photomicrographs of certain of these cell types can be found in Evert (2006), Fahn (1990), Beck (2005), Rudall (2007), Gunning (2009), MacAdam (2009), Wayne (2009), Beck (2009), Assmann and Liu (2014) and Noguchi et al. (2014).
Table 1.1 Plant cell types.
Cell types | Characteristics | References |
Epidermal cells | Unspecialized cells; one layer of cells in thickness; outer covering of various plant parts; variable in shape but often tabular | Evert (2006) |
Examples | ||
Guard cells | Specialized epidermal cells; crescent shaped; contain chloroplasts; form defines stomatal pore | Wille and Lucas (1984) |
Subsidiary cells | Cells which subtend the stomatal guard cells | http://anubis.ru.ac.za/Main/ANATOMY/guardcells.html |
Trichomes | An outgrowth of an epidermal cell; can be unicellular or multicellular | Callow (2000) |
Parenchyma cells | Isodiametric, thinâwalled primary cell wall; in some instances may have secondary walls; not highly differentiated; function in photosynthesis, secretion, organic nutrient and water storage; regeneration in wound healing | Evert (2006) and Sajeva and Mauseth (1991) |
Examples | ||
Transfer cells | Specialized parenchyma cells; plasmalemma greatly expanded; irregular extensions of cell wall into protoplasm; transfer dissolved substances between adjacent cell; occur in pith and cortex of stems and roots; photosynthetic tissues of leaves; flesh of succulent fruits; endosperm of seeds | Dashek et al. (1971) and Offler et al. (2003) |
Collenchyma cells | Lamellar or plate collenchyma, with thickenings on the tangential walls | |
Vascular cells | Evert (2006) | |
Phloem | ||
Sieve cells | ||
Sieve elements | ||
Companion cells | Specialized parenchyma cells; possess numerous plasmodesmatal connections | Oparka and Turgeon (1999) |
Albuminous cells in gymnosperms | Absence of starch; cytoplasmic bridges with sieve cells; dense protoplasm, abundance of polysomes, hig... |
