Parenchymal cells.
Animal cells and some protists e.g., amoeba, have no cell wall. Plant and fungal cells have walls. In plants the wall is composed of cellulose while fungal cells have cell walls composed of chitin.
Squamous cells are flat. If you take a swab of your check, you can see cells that fit this description under a microscope.
Since humans are such complex beings, we are composed of many different types of cells, each type specialized to perform a different function. We have brain cells, nerve cells, kidney cells, liver and pancreatic cells, muscle and bone cells, skin cells, and so much more.
What is composed of only one type of molecule
Groups of cells that work together are called tissues.
Fibroblasts
Primarily, Organisms are composed from Somatic, or Body, Cells. The list of Types of Somatic Cells is bio-extensive.
Animal cells and some protists e.g., amoeba, have no cell wall. Plant and fungal cells have walls. In plants the wall is composed of cellulose while fungal cells have cell walls composed of chitin.
connective tissue
Skeletal muscle cells
hard plug composed of sebum and dead skin cells. The mildest type of acne.
No, cells are composed of all macromolecules: proteins, lipids, carbohydrates, and nucleic acids. Cells definitely contain protein in the membranes and organelles, but they're not wholly made up of protein or are a type of protein.
Lions have eukaryotic cells, which are cells that have a membrane-bound nucleus and other organelles. These cells are specialized for various functions such as movement, digestion, and reproduction, allowing lions to carry out necessary bodily functions.
Squamous cells are flat. If you take a swab of your check, you can see cells that fit this description under a microscope.
Plants, Bacteria and Humans
Multi-celled organisms are composed of many cells. Some examples are insects, mushrooms, horses, daisies, trees, etc.
Plantae cells are Eukaryotic. The plantae is multicellular and goes through photosynthesis. There are moss, ferns, trees, and flowing plants that are composed of plantae cells.
