View these slides to explore types of cells and their structures and functions.
Select the characteristics for each type of cell.
Only some have cell walls
Ribosomes only present suspended in the cell's cyotplasm
Nucleus present
Organelles without a membrane.
No nucleus
Has a cell wall
Ribosomes suspended in the cell's cytoplasm or attached to the endoplasmic reticulum
Has many organelles with membranes
