What else can I help you with?
Do people have animal cells or plant cells?
Humans are composed of animal cells. Plants are composed of plant cells
What are plant walls composed of?
cells
Who theorized that animals are composed of cells?
Theodor Schwann and Matthias Schleiden are credited with proposing the cell theory in the 19th century, which states that all living organisms are composed of cells. Rudolf Virchow later added to this theory by stating that cells only arise from pre-existing cells.
Is elodea an eukaryotic cell?
It is a plant that is composed of eukaryotic cells.
What substance is composed in midlle lamella cells?
The middle lamella of plant cells is primarily composed of pectin. Pectin is a complex polysaccharide that helps to cement adjacent cells together, providing structural support and adherence between plant cells.
Do all plant cells walls contain chitin?
Plant cell walls are composed of Cellulose
What is a nonliving material that makes up the cells wall of plant cells?
Cell walls are composed of cellulose.
Do you have animal cells in your body?
Humans are composed of animal cells. We don't do photosynthesis (have chlorophyll) like plants do! So humans do not have plant cells.
Are all living organisms composed of cells or cellulose?
All living organisms are cells or are composed of cells. Only plant cells have cellulose which makes them stiff and upright. Plants need cellulose because they don't have bones like you and me.
Plant cells all have what composed of cellulose?
Plant cell walls are composed of cellulose, a structural polysaccharide that provides rigidity and support to the cell.
What are the three differences between animal and plant cell?
Plant cells have cell walls composed of, basically, cellulose. Animal cells have no cell walls. Plant cells have chloroplasts with which they preform photosynthesis, making them autotrophs. Animal cells are all heterotrophs. Plant cells have large central vacuoles that have catalytic capabilities and storage facilities. Some animal cells have smaller vacuoles. Animal cells have lysosomes, plant cells do not. Animal cells have centrioles in the centrosomes, plant cells do not.
What organelles is composed of the sugar cellulose and functions to give plant cells support?
The organelle composed of the sugar cellulose that provides support to plant cells is the cell wall. The cell wall is a rigid structure surrounding the cell membrane, maintaining the cell's shape and protecting it from mechanical damage.
