20. How can a microscopic paramecium and a large giraffe both be described by the cell theory?

Answer:

   The two types of cell are:

-Eukaryotic cell

-prokaryotic cell

   Description:

Eukaryotic cell: These are organisms who have a nucleus enclosed within a nuclear envelop. It does not have a cell wall unlike prokaryotes. It has mitochondria and other cell organelles.

Prokaryotic cell: Organisms with no distinct nucleus and other major cell organelles.

   We humans are made up of Eukaryotic cell type as we have membrane bounded nucleus and all the essential major organelles to perform vital body function. Humans have complex organization of cells. Cells have cytoskeleton and organelles surrounded by cytoplasm.

   Bacteria are prokaryotic, as they have cell wall made of peptidoglycan, they lack nucleus and membrane bounded organelles. Hence considered to be unicellular life forms.

   Similarities between prokaryotes and Eukaryotes:

   -Both have cell membrane

   -Both have genetic material

   - Both have ribosome

   -Both have cytoplasm

   -Both have vacuole

   5. The cell wall is like House because it protects the family members inside as cell wall protects the substance inside the cell.

   6. The cell membrane is like airplane because it allows passenger to come in and go out the way cell membrane allows substances to enter and leave.

   7.The vacuoles is like a basketball because both acts as storage, basket ball stores air and vacuole store other substance.

   8.nucleus

   9.Vacuole

   10.Cytoplasm

   11. Cell wall

   12.Chloroplast

   13. Nucleus

   14.Cheek will have greater number of Mitochondria as great function and more energy required which will be released in form of ATP.

   15. Differences:

1.Animal cell do not have cell wall whereas plant cells have cell wall.

2. Animal cells have several small vacuoles whereas plant cells have one large nucleus.

3.Plant cells have chloroplast but Animal cells don not.

   16.Plants have single large vacuole as it performs two main function

i)To keep the plant upright

ii)To store water

Large vacuole protect cell from potential harm.

   17.In plants chloroplast main function is to synthesis food whereas in humans there is no such need as they get sugar from the food they eat.

   18. components of cell theory:

1. All living things are composed of cell.

2.Cells are basic units of structure and function for two living beings.

3.All cells come from pre existing cells.

   19. All living things are composed of cell:

Experiment:

Cut sections can be taken of Human hair, onion and bacterial colony. Slides can be prepared and viewed under microscope to confirm the presence of cell.

   20. They can be distinguished on basis of microscopic result A Giraffe is a multicellular organism hence multiple cells will me visible under microscope where as a Paramecium is single cell organism.

Physical Models Activity

You have explored some interesting, informative, and amusing examples of models. Now it's time to get creative and make your own model. Here is the requirement checklist for your model:

✔ Model types can include drawings, diagrams, physical models, virtual simulations, or videos.
✔ Models must be created by you, not something selected from an online or outside source.
✔ Submit a presentation, picture, video, or screenshot of your model.
✔ Submit a one-paragraph summary describing the topic you chose, your model, what it represents, how you made it, and the specific science involved. It is important that you are using science terminology and are accurate.
Now that you know how to create and submit your model, you will need to choose a topic for your model. Choose one of the three topics listed below. Select each topic for an overview.

Conservation of Mass
Atomic Theory
Thermal Energy
