What is the function of the Cell Membrane?
Maintains integrity of the cell, controls the passage of materials into and out of the cell, and provides for signal transduction
What is the structure of the Cell Membrane?
Membrane mainly composed of protein and lipid molecules
Describe the structure of the Endoplasmic Reticulum?
Complex of connected, membrane-bound sacs, canals and vesicles
What is the function of the Endoplasmic Reticulum?
Transports materials within the cell, provides attachment for ribosomes, and synthesizes lipids
What us the structure of the Golgi Apparatus?
Group of flattened, membranous sacs
What is the structure of the Mitochondria?
Membranous sacs with inner partitions
What is the function of the Mitochondria?
Release energy from food molecules and transform energy into usable form
What is the structure of the Lysomes?
Membranous Sacs
What is the function of Lysomes?
Contain enzymes capable of digesting worn cellular parts or substances that enter cells
What is the structure of Peroxisomes?
Membranous vesicles
What is the function of Peroxisomes?
Contain enzymes called peroxidases, important in the breakdown of many organic molecules
What is the structure of a Centrosome?
Nonmembranous structure composed of two rodlike contrioles
What is the function of a Centrosome?
Helps distribute chromosomes to new cells during cell division and initiates formation of cilia
What is the strucure of Cillia?
Motile projections attached to basal bodies beneath the cell membrane
What is the function of Cillia?
Propel fluids over cellular surface
What is the structure of Flagella?
Motile projections attached to basal bodies beneath the cell membrane
What is the function of Flagella?
Enable sperm cells to move
What is the structure of Vesicles?
Membranous sacs
What is the function of Vesicles?
Contain substances that recently entered the cell and store and transport newly synthesized molecules
What is the structure of Microfilaments and Microtubules?
Thin rods and tubules
What is the function of Microfilaments and Microtubules?
Support cytoplasm and help move substances and organelles within the cytoplasm
What are the structure of Nuclear envelope?
Porous double membrane that separate that nuclear contents from the cytoplasm
What is the function of Nuclear envelope?
Maintains the integrity of the nucleus and controls the passage of materials between the nucleus and cytoplasm
What is the struture of the Nucleolus?
Dense, nonmembranous body composed of protein and RNA molecules
What is the function of the Nucleolus?
Site of Ribose formation
What is the structure of Chromatin?
Fibers composed of protein and DNA molecules
What is the function of Chromatin?
Contains cellular information of synthesizing proteins
What is the function of the Golgi apparatus
Packages and modifies protein molecules for transport and secretion
What is the structure of a ribosome?
Particles composed of protein and RNA molecules
What is the function of a ribosome?
Synthesize Proteins
