Plant cells possess a cell wall, plastids and a large central vacuole, which are absent from animal cells. Animal cells possess centrioles, which are absent from almost all plant cells.
Ref: NCERT Class 11 Biology Chapter 8: Cell: The Unit of Life Endomembrane System - ER Golgi Lysosome Vacuole
The tonoplast is the membrane surrounding the vacuole. It facilitates the transport of several ions and other materials into the vacuole against their concentration gradients.
Ref: NCERT Class 11 Biology Chapter 8: Cell: The Unit of Life Eukaryotic Cell - Cell Wall and Cell Membrane - Fluid Mosaic Model
Vacuoles may occupy up to 90 per cent of the volume of a plant cell. A vacuole is a membrane-bound cytoplasmic space enclosed by the tonoplast.

The Filiform Apparatus consists of finger-like projections at the micropylar end of the Synergids. Its primary function is to secrete chemical attractants to guide the entry of the pollen tube into the synergid.
