Cell Organelles and their Function

Be able to fill out the following chart! Organelle Where it is/What it looks like Function Plasma Membrane Cell Wall Nucleus Nucleolus Smooth/Rough Endoplasmic Reticulum Golgi Apparatus Lysosome Vacuole Cytoplasm Chloroplast Centriole Mitochondria Cytoskeleton Cillia/Microvilli/Flagella

Be able to fill out the following chart! Organelle Where it is/What it looks like Function Plasma Membrane Outside boarder of the cell, made of phospholipids Lets things in and out of the cell Cell Wall Only in plant cells, outside of the cell Gives plants structure Nucleus Middle of the cell Brain of the cell, contains DNA Nucleolus Inside the nucleus Makes Ribosomes Smooth/Rough Endoplasmic Reticulum Right outside the nucleus, smooth vs. Rough Smooth – Makes Lipids, Rough – Makes Proteins Golgi Apparatus Flat sacks outside of the ER Packages, and makes proteins functional Lysosome Used for destroying cell structures when they are old Destroys old cell parts Vacuole Holds water and nutrients Cytoplasm The liquid part of the cell including organelles Site for chemical reactions Chloroplast Only in plant cells, photosynthesis happens here. Site of Photosynthesis Centriole Used in mitosis, two cylinders Helps during cell division Mitochondria Found all over the cell, oval with a squiggly line. Site of Cellular Respiration - Energy Cytoskeleton All over the cell Gives the cell structure, helps in moving cells parts around. Cillia/Microvilli/Flagella Outside of the cell, helps to move the cell or things next to the cell. Helps move the cell or interact with the environment.

The cell would be less able to break down molecules that come from the cytoplasm. The cell would produce more proteins than it needs The cell would have chloroplasts that appear yellow instead of green. The cell would be less able to regulate the amount of fluid in its cytoplasm. If a cell’s lysosomes were damaged, which of the following would most likely occur?

The cell would be less able to break down molecules that come from the cytoplasm. answer

DNA Golgi Complex Mitochondria Lysosomes A cell from heart muscle would probably have an unusually high number of:

Mitochondria Answer

DNA can be found in two states what are the?

Answer Chromatin – like spaghetti on a plate Chromosomes – look like X’s Answer

Use the picture of a cell membrane for the next question.

What is the molecule labeled B in the picture? Polar phosphate molecules Hydrophilic fatty acid tails Non-polar phosphate molecules Hydrophobic fatty acid tails What is the molecule labeled B in the picture?

Hydrophobic fatty acid tails Part of the phospholipid bilayer Answer

t/f: The cell membrane is a phospholipid bi-layer with polar phosphate heads on the outside and non-polar fatty acids on the inside.
