What are the major differences in plant and animal cells?

Animal cells:

• Glycoprotein extracelluler matric

• Centrioles

• tight junctions, desmosomes, gap junctions

Plant Cells:

• Chloroplasts

• Cell walls (cellulose)

• Large central vacuole

• Plasmidesmate

What are the parts of the Nuclear envelope?

• outer membrain

• inner membrane

• nuclear pores

What are the parts of the endomembrane system?

• nuclear envelope

• endoplasmic reticulum

• golgi apparatus

• lysomes

• vacuoles

• plasma membrane

connected by transfer vesicles

What is the structure and function of the golgi apparatus

Cisternae pouches that transport, modify, and package - proteins and lipids into vesicles

The smooth cis face receives proteins and lipids

The trans face sends out modified vesicles

What is the structure and function of the Endoplasmic Reticulum

A smoother outer ER that produces other substances needed by the cell and DOES NOT have ribosomes

A rought ER that has ribosomes that create proteins

What is the structure and function of Lysosomes

An orb of membrane containing digestive enzymes that recycle old cell parts. Also help kill bactira this way

What is the structure and function a vacuole

Generally to take up space in a molecule allowing it to have a larger surface area for the amount of (non vacuole) components in the cell to get enough sustenance

What are the similarities between Mitochondria and Chloroplast?

Similarities:

• size

• double outer membrain

• grow and reproduce independently within cells

• have their own ribosomes and DNA molecules

What part of the Cytoskeleton is this (blue is nucleus)

Microtubules / Tubilin Polymers

What part of the Cytoskeleton is this

Microfilaments / Actin Filaments

What part of the Cytoskeleton is this

Intermediate Filaments

What are the functions of Microtubules, microfilaments, and intermediate filaments?

all are for maintenance of cell shape

Microtubules : Compression-resisting, Cell motility (ability to move), chromosome movments in cell division, organelle movements

microfilaments : tension-bearing, changes in cell shape, muscle contractions, division of animal cells

intermediate filaments: anchorage of nucleus and otehr organells, formation of nuclear lamina

What is a tight Junction?

a junction/structure that prevents fluid from getting between cells/ moving across a layer of cells

What is a gap junction?

A junction that allows ions and small molecules to move between cells

What is a Desmosomes

Anchors cells together, has intermediate filliments
