They have no cell walls;
They usually have nervous coordination and are able to move from one place to another;
They often store carbohydrate as glycogen.

Question 3

fungi

Answer 3

dont carry out photosynthesis
made from hyphea
yeast is single celled
cell walls made of chitin
they do saprotrophic nutrition
they store carbohydrates as glycogen

Question 4

bacteria

Answer 4

These are microscopic single-celled organisms;
They have a cell wall, cell membrane, cytoplasm and plasmids;
They lack a nucleus but contain a circular chromosome of DNA;
Some bacteria can carry out photosynthesis but most feed off other living or dead organisms.
