Interphase

Among/Between Condition


--the longest phase


--DNA replicates


--cell prepares to divide

Prophase

Before condtion


--Chromatin condenses into chromosomes


--Spindle fibers appear


--Chromosomes pair up


--Nucelar membrane breaks down

Metaphase

Beyond or after condition


--Chromosomes line up in the middle of cell


--Centromeres attach to spindle fibers



Anaphase

Back or a new condition


--Chromosomes separate and move away from each other


Telophase

For a distant condition


--Chromosomes stretch


--New nuclear membrane forms

Cytokinesis

Cell Monument


--Cytoplasm divides


--Cell membrane pinches in and two new cells are formed

Nucleus

large, round/oval structure usually located near the center of the cell




it is the control center for all cell activities

Cell Membrane

Thin, flexible envelope that surrounds the cell




it allows the cell to change shape and controls what goes in and out

ER

Thin, flexible envelope that surrounds the cell




it allows the cell to change shape and controls what goes in and out

Ribosomes

Small grain-like bodies made mostly of RNA and produced in the nucleolus




Proteins are constructed here

Nucleolus

Small, dense object found in the middle of the nucleus




it makes the RNA for the cell

Cytoplasm

Jelly-like area between the nucleus and the cell membrane




Helps the organelles move throughout the cell

Mitochondria

Tiny bean-shaped structures in the cytoplasm with a smooth outer membrane and a greatly folded inner membrane




They supply the energy for teh cell by transforming sugar into energy

Chromosomes

Rod-shaped bodies in the nucleaus made of DNA




They contain the info to run the cell and pass on hereditary traits of the cell to new ones

Lysosomes

Small round structures in teh cytoplasm that contains chlorophyll.




it captures the sun's energy to produce food, in teh form of sugar, for itself through photosynthesis

Vacuole

Large, round sac in the cytoplasm that stores water, food or wastes

Organelles

Include the cell wall, cell membrane, and nucleus





Cell Wall

The rigid layer of nonliving material that surrounds plant cells

Are cells alive?

yes

Plants cells

have chloroplasts

Four types of animal cells

1. Bone


2. Brain


3. Skin


4. Muscle



Do all cells do the same thing?

NO

Fastest growing organ in the body

skin

What tells cells what to do?

Genes

What makes up genes?

DNA

How many chromosomes do we get from each parent?

23

Two types of blood cells

Red and white blood cells
