Answer:
projections that help them move
Explanation:
Euglena and paramecium both belong to the Kingdom Protista. They are very minute single cellular organisms but have many differences among them. Paramecium is more similar to animals in many of its characteristics while Euglena is more similar to plants in its characteristics. This is because Euglena just like plants can make their own foods through chloroplast while paramecium just like animals cannot make own food.

. Paramecium have projections called cilia around the whole body while Euglena has a whip like flagella which helps it to move.
