Cell Structure
Term | Definition |
---|---|
Cell membrane | a layer that surrounds the cell, this provides structure and protection, it is semi-permeable |
Cell wall | found only in the plant cell and provides extra structure and protection for the plant |
Centriole | are contained in the centrosomes and help the cell to divide during mitosis |
Centrosome | create microtubules |
Vacoules | provide storage for the cell for materials such as water, there is only one in the plant cell and it is larger, whereas in the animal cell there are many small ones |
Vesicles | small storage organelles that move material in and out of the cell |
Endoplasmic Reticulum - Smooth | makes lipids and modifies proteins that are then transported throughout the cell |
Endoplasmic Reticulum - Rough | has ribosomes bound to its membrane |
Ribosomes | are the site of protein synthesis |
Cytoplasm | the gel that fills the cell and helps to maintain the pressure inside the cell |
Golgi Body / Complex/ Apparatus | packages proteins and carbohydrates into vesicles for transport out of the cell |
Mitochondria | nicked named the powerhouse of the cell because they provide energy for the cell, it is also the site of cellular respiration |
Nucleus | is the control center of the cell, it directs many of the functions of the cell and holds the DNA |
Nucleolus | is inside of the nucleus and aids in the production of protein |
Lysosome | is the digestive system of the cell, it helps to break down waste molecules |
Chloroplasts | converts light energy from the sun into sugar that can be used by the plant cell for energy through the process of photosynthesis |
