Exercis Bio 201 Lab- Exercise 4- The Cell - Anatomy And Division

Front 1

Nucleus

Back 1

Contains the Cell's genetic material and directs cell activities

Front 2

Chromatin

Back 2

Organized DNA which condenses to form two chromosomes

Front 3

Nuclear Membrane (envelope)

Back 3

Two separate Membranes with nuclear pores

Front 4

Nucleolus (nucleoli)

Back 4

Dark staining spherical bodies within nucleus

Front 5

Plasma Membrane

Back 5

Seperates Cell from environment; Supports Cell contents; Regulates what enters and exits the cell; Plays a role in communication between Cells.

Front 6

Cytoplasm

Back 6

material between the cell membrane and the nucleus

Front 7

Organelles (What are they)

Back 7

Small structures w/i cytosol. specialize subcellular structures w/ specific functions.

Front 8

Organelles (consist of)

Back 8

ribosomes, endoplasmic reticulum, Golgi apparatus, lysosomes, peroxisomes, mitochondria, cytoskeletal elements, and centrioles

Front 9

Ribosomes

Back 9

Composed of RNA and Protein; are site of protein synthesis.

Front 10

Rough Endoplasmic Recticulum

Back 10

Produces proteins that are secreted from the cell. Transports cellular substances (primarily proteins) around the cell. Involved in Phospholipid and cholesterol synthesis.

Front 11

Smooth Endoplasmic Recticulum

Back 11

Major Site of lipid and carbohydrate synthesis

Front 12

Golgi Apparatus

Back 12

Closely Packed Membranous Sacs which Collect, Package, and Distribute proteins and Lipids.

Front 13

Mitochondria

Back 13

Produces ATP via aerobic cellular respiration

Front 14

Centrioles

Back 14

cylindrical organelles located in the centrosome. Direct formation of mitotic spindle during cell division. Form bases of cilia and flagella.

Front 15

Interpahse

Back 15

DNA and Organelles replicate (except nucleus) NOT part of mitosis. The time between cell division.

Front 16

Prophase

Back 16

Chromatin condenses into chromosomes, centrioles move toward the end of the cell. Nucleus and Nuclear envelope dissapear. Spindle Fibers Appear.

Front 17

Metaphase

Back 17

Chromosomes align in center, Spindle Fibers attach

Front 18

Anaphase

Back 18

Chromosomes separate and work towards opposite ends near centrioles.

Front 19

Telophase

Back 19

Migration of chromosomes complete. Chromosomes unravel back into chromatin; nuclear envelope forms.

Front 20

Cytokinesis

Back 20

Cell "cutting" cell separate into two individual cells.
