Cell Organelles

Definition of Cytoskeleton

• Network of proteins that are constantly changing to meet the needs of the cell.

• Storehouse for genetic information.

• Tiny organelles that link amino acids together to form proteins during protein synthesis.

• Small structure within a cell consisting of a fluid enclosed by a lipid bilayer membrane.

what are the 3 fibers in the cytoskeleton?

• Micro tubules: Long hollow tubes.

• Microfilaments: Two intertwined strands of actin.

• Chromatin:

  DNA and proteins

• vesicle:

  Small structure within a cell consisting of a fluid enclosed by a lipid

  bi-layer membrane.

• Intermediate filaments: Fibrous proteins super coiled into thicker cables.

what is the nucleus's function?

• Converts food into energy-rich usable molecules for the cell (ATP)

• Gathers simple molecules and combines them to make more complex molecules.

• To be the storehouse for genetic information.

  and to make DNA available when needed for Protein Synthesis and Mitosis.

• Produce proteins and lipids.

Click all that apply: What are parts of the nucleus

• Nuclear envelope: surrounds the nucleus and contains pores for things to enter and exit.

• Chromatin: DNA and proteins inside the nucleus. When the cell starts reproducing, it condenses to chromosomes.

• Nucleolus: primary function is to assemble ribosomes.

what is the purpose of the rough ER?

• To be the Storehouse for genetic information.

• to transport proteins and lipids by forming a vesicle and moving to the Golgi Apparatus or Membrane.

• To maintain the cell shape, chromosome movements in cell division, organelle movements.

What are ribosomes?

• Tiny organelles that link amino acids together to form proteins during protein synthesis.

• Small structure within a cell consisting of a fluid enclosed by a lipid bilayer membrane.

• Known as the powerhouse of the cell.

• Storage bubbles contained in both plant and animal cells.

what is the function of golgi bodies?

• Primarily used to store nutrients and water.

• transport molecules.

• Converts food into energy rich usable molecules for the cell (ATP)

• Gathers simple molecules and combines them to make more complex molecules.

  Packages them in vesicles and stores them or sends them where they need to go.

  Builds lysosomes.

What are vesicles?

• Specialized vesicle that contains enzymes for breaking down expired cell organelles or other objects that need to be digested.

• Storage bubbles contained in both plant and animal cells.

• Small structure within a cell consisting of a fluid enclosed by a lipid bilayer membrane.

Vacuoles are...

• Storage bubbles contained in both plant and animal cells.

• Found exclusively in plant cells, algae, fungi, and some bacteria.

• Jelly-like filling within the cell.

• Composed of a phospholipid-bilayer
