Describe the main differences in structure between plant and animal cells

Plasmodesmata is present in plants but not animal cells
(Plasmodesmata are narrow channels that act as intercellular cytoplasmic bridges to facilitate communication and transport of materials between plant cells. The plasmodesmata serve to connect the symplastic space in the plant and are extremely specialized channels that allow for intercellular movement of water, various nutrients, and other molecules (including signalling molecules) . Plasmodesmata are located in narrow areas of cell walls called primary pit fields, and they are so dense in these areas (up to one million per square millimeter) that they make up one percent of the entire area of the cell wall :

Centrioles are absent in higher plants but are present in animal cells

Large central vacuole filled with cell sap in plant cells whereas small and numerous digestive vacuoles in animal cells.

Plant cells lacks lysosomes while animal cells contain lysosomes.

Presence of tonoplast in plant cells but not in animal cells.
tonoplast

(Science: plant biology) membrane that surrounds the vacuole in a plant cell. The cell membrane of plants surrounding the vacuole which is selectively permeable, and regulates the movements of ions around the cell.

Presence of chloroplast in plant cell but not in animal cell.

Presence of cellulose cell wall in plant cell but not in animal cell.

Explain how lysosomes differ from ribosomes:

Lysosomes are 0.1 to 0.5 micrometre in diameter while ribosomes are 20 nanometres in diameter

Lysosomes are sacs formed from Golgi apparatus while ribosomes are made up of protein and RNA.

Lysosomes are not bound to endoplasmic reticulum while ribosomes may be attached to endoplasmic reticulum.

Lysosomes are involved in autolysis while ribosomes are involved in protein synthesis.

Lysosomes are membrane bound while ribosomes lack membrane

Ribosomes are made up of large and small subunits while lysosomes do not contain any subunits.

Enzymes in lysosome are hydrolytic while enzymes in ribosomes are used for peptide bond formation. Lysosome enzymes such as protease and ribosome contains peptidyl transferase.

Outline the structure and function of the Golgi body in cells:

Made up of flattened membrane sacs
Consists of cis and trans side
formed from vesicles from rough edoplasmic reticulum
Involved in chemical modification of protein,forming glycoproteins.
Involved in synthesis and transport of lipids
Plays a role in cell wall formaton in plant cells
