Organelle Function Activity

Flashcards covering the functions of various animal cell organelles as listed in the 'Organelle Function Activity' lecture notes.

Chromatin

DNA form found in the cell during times of non-division.

Centrioles

Organize the microtubules during cellular division, form the base for cilia and flagella.

Cytoskeleton

Aid in maintaining cell shape, involved in intracellular and cellular movement; also part of the centrioles.

Golgi Apparatus

Packages, modifies, and separates proteins for secretion from the cell.

Intermediate Filaments

Found in the nuclear envelope; help maintain shape.

Lysosomes

Contains low pH and enzymes that facilitate intracellular digestion.

Microfilaments

Involved in muscle contraction. Composed of actin.

Microtubules

Responsible for maintaining cell shape, vesicular transport, and cell movement.

Mitochondria

Site of ATP synthesis in the presence of oxygen, contains its own DNA and ribosomes.

Nuclear Envelope

Double membrane that surrounds the nucleus; contains pores for transport into and out of the nucleus.

Nucleolus

Site of synthesis of ribosome components.

Nucleus

Houses the DNA; involved in providing information to make proteins; considered to be the 'control center' of the cell.

Peroxisomes

Contains enzymes that remove toxic chemicals (i.e. hydrogen peroxide) from the cell.

Plasma Membrane

Cell's external barrier; provides selective transport and cell-cell recognition, participates in signal transduction.

Ribosomes

Considered to be both a protein and organelle. Involved in making a protein based on information stored in mRNA.

Rough Endoplasmic Reticulum

Responsible for assisting with folding and modification of proteins destined for secretion or insertion into the plasma membrane.

Smooth Endoplasmic Reticulum

Site of lipid synthesis, steroid hormones synthesis, and drug detoxification.

Vesicles

Double-membraned packages that bring cellular material from one location to another in the cell. Involved in intracellular membrane trafficking.
