Can you guys please help me fix this

Instructions: Review the content in Chapter 3 of the textbook and prepare a table or diagram that compares the components and characteristics of prokaryotic and eukaryotic cells. Be sure to include both (1)similarities- characteristics in common and (2) differences- characteristics unique to each cell type.

My project:

Prokaryotic and Eukaryotic Cells

Similarities between Prokaryotic and Eukaryotic :

- Both are made of cells.

- Cell is covered by a lipid bilayer membrane

- Both reproduce and multiply for grows

- Their genetic material is either DND or RNA

Differences:

Prokaryote eukaryote

absent

nucleus

present

smaller

ribosome

larger

Fold and condense prokaryotic dna

dna

Wrap their dna around proteins called histones

absent

Membrane bound organelle

present

absent

chloroplast

present

Absent

mitochondria

present

My teachers notes :

Both cell types have cytoplasm.

Be specific and include a list of membrane bound organelles in eukaryotic cells.

1. What do you think the cell structure that Robert Hooke observed under his

microscope was? What part of the plant cell was this?

2. List the organelles not present in prokaryotic cells.

3. We know that in eukaryotic cells, metabolic activity and synthesis happened

in membrane bound organelles. Does this mean prokaryotic cells do not

have metabolic activity? Explain your answer and state where you think this

process might occur in a prokaryotic cell.

4. There were no chloroplast in the onion cell preparation, yet onions are

plants. Explain why.

5. List three similarities and three differences between plant and animal cells

that you observed today.
