Q.Give a detailed comparative account of a typical plant cell and a typical animal cell, listing at least six distinguishing structural features, and describe the structure and functions of the cytoskeleton, microbodies and centrioles found in eukaryotic cells.

[!TLDR]

Plant vs animal cells differ in wall, plastids, vacuole size, centrioles, lysosome prominence, and plasmodesmata (≥6 features). Cytoskeleton (microtubules/microfilaments/intermediate filaments) gives shape/movement; microbodies (peroxisomes/glyoxysomes) carry out specific enzymatic work; centrioles organise the spindle and give rise to basal bodies. …

Plant and animal cells share the basic eukaryotic plan -- a true nucleus and a common set of membrane-bound organelles -- but differ in at least six structural respects. (1) Cell wall: plant cells have a rigid wall of cellulose, hemicellulose, pectin and protein; animal cells have none, bounded only by the plasma membrane. (2) Plastids: chloroplasts, chromoplasts and leucoplasts occur only in plant cells. (3) Vacuole: a plant cell typically has one large central vacuole occupying up to 90% of its volume; animal cells have small or no vacuoles (apart from specialised contractile/food vacuoles in some protists). (4) Centrioles: generally present in animal cells, organising the mitotic spindle, but generally absent in higher plant cells (present in some lower plants). (5) Lysosomes: more numerous and prominent in animal cells, where the vacuole does not take over their digestive role as it partly does in plant cells. (6) Plasmodesmata and glyoxysomes: plant cells are connected by plasmodesmata through the cell wall, and germinating plant seeds contain glyoxysomes -- neither has a true equivalent in animal cells.

Within both cell types, the cytoskeleton -- a network of microtubules (tubulin-based, forming the spindle, centrioles, cilia and flagella), microfilaments (actin-based, involved in cytoplasmic streaming and, with myosin, muscle contraction) and intermediate filaments (providing tensile strength and anchoring organelles) -- gives the cell mechanical support, maintains its shape, and enables movement of the cell and its internal components.

Microbodies are small, membrane-bound organelles carrying specific enzyme sets: peroxisomes, found in both plant and animal cells, contain catalase and oxidative enzymes that generate and then safely break down hydrogen peroxide, and in plants are involved in photorespiration; glyoxysomes, found specifically in germinating oil-rich seeds, contain the glyoxylate-cycle enzymes that convert stored fat into carbohydrate for the young seedling. …
