Viruses, I think. It has to use other cells to reproduce.
(But I'm not really sure.)
plant-like: contain chlorophyll and make their own food using photosynthesis, have cell walls, and no specialized ways to move from place to place. animal-like: cannot make their own food; they capture other organisms for food, do not have cell walls, and have specialized ways to move from place to place. fungus-like: cannot make their own food; they absorb food from their surroundings, some organisms have cell walls; others do not, and have specialized ways to move from place to place.
Fungi actually don't make their food, they're heterotrophic, or decomposer, even though they have cell walls. You find fungi near their food source.
Multi celled, eukaryotic, heterotrophic
Their cells have cell walls and chloroplasts. They make their own food through photosynthesis.
You actually can't, but if you have maybe, fatty skin or fatty tissue then the cell walls are bound to get bigger.
Carbohydrates and Proteins
stronger
cellulose
If you are referring to plant cell walls, then they are made up of primarily cellulose and carbohydrates. Even though carbohydrates do make up cell walls in plants, cellulose (a polymer of glucose {consists of many glucose molecules}) is the primary structural component of a plant cell wall.
chlorophyl Plants take in nutrients by absorption from their environment, and animals take in nutrients by bringing food inside their bodies and digesting it internally. Many plants, but not all, produce food by photosynthesis (using chlorophyl). Animals also have no cell walls, and all plants have cell walls.
Cellulose
There was no cell wall in the cheek cells because animals and human cells do not contain a cell wall; they only have a cell membrane. Cell walls can be found in plant cells
