Prokaryotic Cells Prokaryotic cells = BACTERIA It has no true nucleus or organelles. Instead it just has DNA, RNA, chrosomes, cytoplasm, a cell wall, and cell membrane. There are no organelles The “POOR PRIMITVE PROKARYOTE”

Eukaryotic Cells Eukaryotic cells are plant, animal, and protist animal cells!! Have cell organelles. Eu = means True Karyote = cell

Cell Membrane Eukaryotic and Prokaryotic cells have cell membranes. In the eukaryotic cell membrane is the outmost part of an animal cell, controls what enters and exits in the plant cells (Figure 1).

The Cell Wall Like the Cell membrane, the cell wall also is in both Prokaryotic and Eukaryotic cells. Cell membranes are found on the outermost part of plant and bacteria cells, they are flat and rigid, are used for support in the cell.

Nucleus The nucleus is ONLY found in the Eukaryotic cells. It is located in the middle of animal cells It contains DNA, controls the activities of the cell, and cellular reproduction.

Ribosomes When looking at a picture of a cell you can locate the ribosomes very easily. They are the small dots seen on the endoplasmic reticulum. The ribosome contains RNA and produce proteins for the cell.

Golgi Apparatus Found in Eukaryotic cells. The job of the Golgi is to modify, sort, and package the proteins of the cells. Its is like the cell post office.

Smooth Endoplasmic Reticulum Found in Eukaryotic cells. Is the envelope to the nucleus. Functions - synthesis of lipids and steroids, metabolism of carbohydrates, regulation of calcium concentration, drug detoxification, attachment of receptors on cell membrane proteins, and steroid metabolism.

Rough Endoplasmic Reticulum If an Endoplasmic Reticulum is rough that means Ribosomes are attached to it. Found in the Eukaryotic Cell. Cell organelle that helps in protein synthesis and packaging of materials into lysosomes.

Vacuole Is found in Eukaryotic cells. Is a sac that plays roles in the cell’s digestion and the release of cell’s waste.

Chloroplast Are found in plant cells (eukaryotic). They produce energy/food for the cell using sunlight. “Green things” in plant cells. The process that occurs in chloroplast is Photosynthesis.

Mitochondrion Found in Eukaryotic cells. Know as the “powerhouse” in the cell. Its job is getting energy for the cell (respiration).

THE ANSWER IS…. D!

What are the differences between structures 1 and 2? A. Ribosomes are produced in structure 1, and DNA is stored in structure 2. B. DNA is stored in structure 1, and ribosome are produced in in structure 2. C. RNA is stored in structure 1, and DNA is stored in structure 2. D. DNA is stored in structure 1, and RNA is stored in structure 2. #4.

THE ANSWER IS…. A!

What are the similarities of prokaryotic and eukaryotic cells? #6

THE ANSWER IS…. They are both cells Both have DNA Have a cell wall Both contain chrosomes.

What is the difference between DNA and RNA?? #7

THE ANSWER IS…. DNA is a double-stranded RNA is single- stranded

TRUE or FALSE… #8 The Golgi Apparatus is an organelle.

THE ANSWER IS…. TRUE!

#9 TRUE or FALSE… A vacuole is a Prokaryotic cell.

THE ANSWER IS… FALSE! A cell can't be prokaryotic, but prokaryotic organisms might have vacuoles.

#10 Identify and explain the function of this organelle.

THE ANSWER IS.... Mitochondria; gets energy for the cell.

#11 What type of cell is this?

THE ANSWER IS…. Eukaryotic; plant cell.

#12 What occurs in Chloroplast?

THE ANSWER IS…. Photosynthesis

#13 What is the difference of Rough ER and Smooth ER? A.Rough = packages lysosomes, Smooth = envelope to the nucleus. B.Rough = envelope to the nucleus, Smooth = packages lysosomes. C. Both do the same thing.

THE ANSWER IS…. A!

#14 Which organelles are ribosomes found on?

THE ANSWER IS… Endoplasmic Reticulum!

#15 What is the difference between the cell wall and the cell membrane?

THE ANSWER IS…. A cell wall is completely permeable and a cell membrane is partially permeable!
