How could you determine whether an unidentified cell was a plant or animal cell?
They are green in color under a microscope because they contain chlorophyll, a naturally green pigment. One of the quickest ways to differentiate between a plant and animal cell is to look at the unstained cell under the microscope. If green organelles are present, it is a plant cell.
Which of the following provided evidence that led to the development of the cell theory?
What evidence led to the development of cell theory? The development of microscopes provided increasingly clear windows to the world of cells. Scientist used microscopes and found cells in every living organism which provided the evidence to a cell theory.
What does the cell wall provide for a cell?
The cell wall surrounds the plasma membrane of plant cells and provides tensile strength and protection against mechanical and osmotic stress. It also allows cells to develop turgor pressure, which is the pressure of the cell contents against the cell wall.
What does the cell membrane do in a plant?
First, along with the cell wall, the membrane helps provide structure. The cell membrane is flexible, allowing plant cells to survive in less than optimal environmental conditions, such as when plants wilt from a lack of water. Second, plant cell membranes control entry and exit from the cell.
What is the cell membrane of a plant cell made of?
Cell membranes are composed primarily of fatty-acid-based lipids and proteins. Membrane lipids are principally of two types, phospholipids and sterols (generally cholesterol)
What color is the cell membrane in a plant cell?
Plant Cell Coloring
|Cell Membrane (orange) Nucleoplasm (yellow) Mitochondria (red) Vacuole (light Blue) Chromatin (gray)||Cell Wall (dark green) Nucleolus (brown) Chloroplasts (light green)|
|Smooth Endoplasmic Reticulum (pink) Rough Endoplasmic Reticulum (pink)|
Where is the cell membrane located in a plant cell?
In plants, the cell membrane is located between the cell cytoplasm and the cell wall. As is the case with animal cells, the cell membrane in plants is a lipid bilayer. It’s made up of phospholipids and also contains protein and carbohydrate molecules.
