Which organisms have got cell walls around their cells?

Animal cells haven’t got cell walls. Viruses aren’t cellular organisms.

These are unicellular organisms.

These are multicellular organisms.

A) Cells are the basic units of life. Every cell has got a cell membrane, organelles and cytoplasm.

B) Plants, animals and fungi have got a nucleus inside their cells.Around the nucleus there is a nuclear membrane.

Read the text and check your worksheet.

C) Bacteria are unicellular organisms. Bacterial cells are very small.

They haven’t got a nuclear membrane, but they have got a cell wall.

Read the text and check your worksheet.

D) Viruses are smaller than bacteria. They aren’t cellular organisms. 

E) Fungi can be unicellular or multicellular organisms. Fungal cells have got a cell wall, but they haven’t got chloroplasts. Fungi can’t use photosynthesis to get food.
