1.1 Cell Structure and Function - Pt.4 Flashcards
Helps keep inner materials organized…
Cytoskeleton
Helps in cell motility and cell organelle movement and is composed of various sized protein fibers…
Cytoskeleton
Large hallow tubes composed of Tubulin protein…
Microtubules
Main function is support or movement. They also work as guide supports for organelle movement within the cell…
Microtubules
Act as anchors during cell division…
Centrosomes/Centrioles
Act as guides or tow ropes for the chromosomes during cell division. And moves chromosomes during the process of mitosis or meiosis…
Spindle Fibers
Help with cell movement an create a wave like movement. Cells have many and are small in length…
Cilia
Helps with movement in cells. Cells have very few and are very long on length. Create a undulating (whipping) movement…
Flagella
Smallest structures in the cytoplasm. Solid rods…
Microfilaments
Composed of Actin or Myosin protein and provide a pulling force. They are abundant in muscle tissue…
Microfilaments
Medium sized structures in the cytoskeleton. These are permanent, solid rocks…
Intermediate Filaments
Commonly composed of keratin protein and try to help reinforce and brace the large microtubules…
Intermediate Filaments
Plants create this structure for protection and durability…
Cell Wall
Made of Cellulose Sugar, found in all plants cells, and is not very strong my itself…
Primary Cell Wall
Composed of Pectin Sugar…
Middle Lamella
Acts as a super glue to hold cells together firmly and helps them grow tall…
Pectin
Composed of Lignin Sugar…
Secondary cell wall
Found inside the primary cell wall allowing it to reinforce the primary wall. Thickest on corners and helps them grow really tall…
Lignin
Outer protective skeleton of the cell plasma membrane in animal cells…
Extracellular Matrix
Communicates with other cells using glycoprotein…
EMC
Compose mainly of glycoproteins and glycolipids…
EMC
Act as stitching to “sew” cells together to make tissues…
Cellular Junctions
Help hold cells together so that they may work together, and some are tunnels for cell to cell communication…
Cellular Junctions
What does it mean that a cell is the “sum of its parts”…
It is the basic unit of life but only when all parts work together to make “life” possible
Characteristics of living things…
- composed o living cells
- responds and adapts to the environment
- uses energy
- grows and reproduces
Helps support and protect the cell…
