PLEASE HELP ME I NEED THIS TOMORROW MORNING (3;30AM)
A. set question
1.) What are the main structural differences plant and animal cells observe under the microscope?
2.) Why do plant cells have a cell wall, and what is their function?
3.) What is the purpose of staining the cells with iodine soulion?
4.) How does the shape of the cells differ between animal and plant cells?,why
5.) What similarities did you observe between plant and animal cells?
B.questions
1.) What part of the plant cell (Onnion cell) did you see using a microscope (HPO) (3 parts only it doesn't have vucoule, cytoplasm, and nucleous)
2.) What part of the animal cell (Cheek cell) did you see using a microscope (HPO) (3 parts only it doesn't have a vacuole, cytoplasm, and nucleus)
Answer (1)
Answer:A. SET QUESTION1.) Main Structural Differences Between Plant and Animal CellsPlant cells have a rigid cell wall, chloroplasts, and a large central vacuole, while animal cells lack these features and generally have an irregular shape. In contrast, animal cells are often more flexible and can vary in shape.2.) Function of the Cell Wall in Plant CellsThe cell wall provides structural support and protection for plant cells, maintaining their shape and preventing wilting. It also regulates the movement of substances in and out of the cell.3.) Purpose of Staining Cells with Iodine SolutionStaining cells with iodine solution enhances the visibility of cellular structures, particularly by highlighting starch in plant cells, making organelles easier to observe under a microscope.4.) Shape Differences Between Animal and Plant CellsPlant cells are typically rectangular due to their rigid cell wall, while animal cells are often irregular or spherical in shape due to the lack of a cell wall, allowing for more flexibility.5.) Similarities Between Plant and Animal CellsBoth plant and animal cells are eukaryotic, containing a defined nucleus and membrane-bound organelles, and they perform essential life functions such as metabolism and reproduction.B. SET QUESTION1.) Parts of the Onion Cell (Plant Cell)Cell Wall: The rigid outer layer that provides structure and support.Chloroplasts: Organelles that contain chlorophyll for photosynthesis, though they may be less visible in onion cells since they are usually found in green plant tissues.Cell Membrane: The semi-permeable membrane that surrounds the cell, controlling the movement of substances in and out.2.) Parts of the Cheek Cell (Animal Cell)Cell Membrane: The flexible outer layer that protects the cell and regulates what enters and exits.Mitochondria: The organelles responsible for energy production through cellular respiration.Endoplasmic Reticulum (ER): The network of membranes involved in protein and lipid synthesis, often visible as a series of folded membranes.
