Variety of living organisms (Animals, Plants and Fungi)

Animal cell structure

No chloroplasts (cant do photosynthesis)

Multicellular

No cell wall (unlike plant cells)

What can animals usually do?

Usually have nervous co-ordination

usually can move from one place to another

Store carbohydrates as glycogen

(Examples, Mammals-Human Insects-Mosquito)

Plant cell structure

multicellular

have chloroplasts so do photosynthesis

have a cell wall made of cellulose

Plant functions

Store carbohydrates as starch or sucrose

Cellulose provides strength and stability

Examples of plants: Cereal-maize and Herbaceous-Legume: Peas and Beans

Fungi Cell structure

Can be both uni or multicellular

No chloroplasts - can’t do photosynthesis

Have a cell wall made of chitin (chitin provides strength rigidity and support)

What do Fungi’s do?

Do Saprotrophic nutrition

Store carbohydrates as glycogen

Examples of Fungi : Classic hyphal structure - mucor and unicellular - yeast

What is saprotrophic nutrition?

The process in which bacteria or fungi obtain nutrients by breaking down and absorbing organic matter from dead and decaying organisms

What are Eukaryotes?

A cell that contains a true membrane bound nucleus and other organelles examples are Animals, Fungi, Plants and Protoctists (protists)
