Features	Fungi	Animal	Plant
Cell	Unicellular – like yeast Or multi-cellular - molds	Unicellular – like protozoa Or multi-cellular	Unicellular like algae Or multi-cellular-
Cell wall	Cell wall is made up of chitin Cell wall gives a definite shape	Not present Absence of cell wall gives an irregular shape (Chitin may be found in some animals.)	Cell wall has cellulosic composition. Cell wall gives a definite shape and rigidity
Chloroplast	Absent Heterotrophic mode of nutrition (majority are decomposers)	absent Animals have heterotrophic nutrition	Chloroplasts consist of double membrane, thylakoid or grana and stroma. Contains photosynthetic pigments like chlorophyll
Lysosome	Lysosome like vacuoles present	Specific to animal cells. They have digestive properties. Mesosome, centrosome usually present	Lysosomes are usually absent. Vacuoles are present
Reproduction	Asexual reproduction through asexual spores. Sexual reproduction through meiosis and mitosis. Mycelium (hyphae produce sexual spores)	Mitosis and meiosis. Gametes like male and female gametes produced.	Mitosis and meiosis Produce gametes like pollens.
