VII. Cell Parts Dissecting the cell

Quick Definitions 1. Homeostasis is the process of maintaining the cell’s environment. 2. Selective permeability is the process where a cell allows some molecules into the cell and not others.

A. Plasma Membrane 1. Cells must control the materials that enter and leave. 2. The PM is the boundary between the cell and it’s environment.

3. PM Structure a) PM is made of a phospholipid bilayer i.Two phospholipid layers ii.Hydrophilic – “likes” water iii.Hydrophobic – “afraid” of water

4. Transport across the PM a) Fluid Mosaic Model b) Transport Proteins

B. Cell Wall 1. Structure = Rigid layer on the outside of the cell membrane a) Think egg shell and membrane 2. Function = cell support and protection 3. Only in plants!

C. Cytoplasm 1. Structure = Clear, jelly-like fluid that fills the cell a)Mostly water 2. Function = Allows molecules to be transported through the cell

Control Centers The Nucleus, Ribosomes, and Centrioles

D. Nucleus 1. Structure: Two membrane layers 1.Nuclear pores allow RNA to exit nucleus a)Nucleolus i. Creates ribosomes 2. Function: 1.The nucleus contains the genetic material for the cell (called chromatin)

E. Ribosomes 1. Structure = very small organelles 1.small dots 2.Found a) in the cytoplasm b) on the ER 2. Function = makes proteins

F. Centrioles 1. Structure: Small barrel shaped organelles a) Made up of bunches of microtubules 2. Function: Involved in cell division 3. Found only in animal cells

Assembly, Transport & Storage Other organelles

F. Endoplasmic Reticulum 1. Structure = 1.Rough ER a) Covered in ribosomes ribosomes 2.Smooth ER ► No ribosomes 2. Function = Where chemical reactions take place in the cell.

G. Golgi Apparatus 1. Structure = Flattened pancake-like layers a)Uses Vesicles to move things 2. Function = Sorts, packages and sends the products of the ER

H. Vacuoles 1. Structure = plastid a) Plant cells have one large vacuole while animal cells have many smaller vacuoles 2. Function = temporary storage of materials

I. Lysosomes ► Structure = plastid ► Function = contain digestive enzymes that break apart cellular waste for re-use

Cellular Energy Chloroplasts and Mitochondria

I. Lysosomes ► Structure = plastid ► Function = contain digestive enzymes that break apart cellular waste for re-use

K. Mitochondria 1. Structure = Double membrane a)Increased surface area for reactions 2. Function = Energy powerhouses for the cell

Support & Locomotion

L. Cytoskeleton 1. Interior network of support in cells 2. Criss-crossed web of small “support beams” a)Microtubules b)Microfilaments

M. Locomotion 1. Cilia a)Short hair-like projections that move in a wave-like fashion 2. Flagella a)Long whip like “tails” 3. Found only in unicellular organisms
