Study Notes
Cell Structure and Function
- All living things are made of cells, which are the basic unit of structure and function for life.
- Organisms rely on their cells to carry out all of the necessary functions of life.
- Organelles are tiny structures inside cells that carry out a specific function within the cell.
- Organelles can be compared to organs in the body.
- Organelles work together as a system to provide various functions for the life of the cells.
- Systems are sets of connected parts that work together to form a cohesive whole.
- The overall goal of the cell system is to make proteins.
- All organelles work together in the cell to make various proteins.
Prokaryotic Cells
- Prokaryotic cells are simpler cells that lack a nucleus and other membrane-bound organelles.
- Have a cell wall, cell membrane, cytoplasm, ribosomes, DNA, and sometimes a capsule.
Eukaryotic Cells
- Eukaryotic cells have a nucleus and other membrane-bound organelles.
- Most eukaryotic cells include:
- Cell membrane: Protects inside cell from outside environment; regulate what goes into and out of cell.
- Cytoplasm: Gel-like substance that occupies space around organelles, protected them from damage.
- Ribosomes: Makes proteins for the cell.
- DNA: Genetic information = code for how cells are built and function.
- Nucleus: “Brain” of the cell - Contains the DNA code for how cell needs to function.
- Endoplasmic Reticulum: Transports proteins throughout the cell.
- Golgi body: Modifies, sorts, and packages proteins for either storage in and removal from the cell.
- Lysosomes: Filled with enzymes that break down “junk”/old organelles that are not working
Comparing Eukaryotic and Prokaryotic Cells
-
Animal Cells
- Have a cell membrane, cytoplasm, ribosomes, DNA, nucleus, endoplasmic reticulum, Golgi body, lysosomes, mitochondria, and vacuoles.
-
Plant Cells
- Have a cell membrane, cytoplasm, ribosomes, DNA, nucleus, endoplasmic reticulum, Golgi Body, lysosomes, mitochondria, vacuoles, cell wall, chloroplasts, and a central vacuole.
Organelle Comparisons
- Mitochondria are sites of cellular respiration where energy in food is converted into energy cells need to function.
- Chloroplasts are found in plant cells and are where photosynthesis takes place.
- Vacuoles store materials such as water, salts and proteins.
- Cell walls provide extra support for the cell, found in plant and bacteria cells.
