The basic unit of living organisms.

Compound Light Microscope

Use a series of lenses to magnify objects in steps.

Uses a beam of electrons instead of light magnify structures up to 500,000 their actual size allowing scientist to see inside cells.

Most of the multicellular organisms we know are made of eukaryotic cells.

Cell membrane bound organelle that manages or controls cellular functions.

With the structure of the better microscopes, scientists observe that all cells contain small, specialized structures.

Most unicellular organisms, such as bacteria, do not have membrane bound organelles.

The model of the plasma membrane.

Has a glycerol backbone, two fatty acid chains, and a phosphate group.

The flexible boundary between the cell and its environment, to allow a steady supply of these nutrients to come into the cell no matter what the external conditions are.

Selective Permeability

A process in which a membrane allows some molecules to pass through while keeping others out.

Move needed substances or waste materials through the plasma membrane.

A fairly rigid structure located outside the plasma membrane that provides additional support and protection.

Traps light energy and gives leaves and stems their green color.

Which are stands of the genetic material, DNA.

Short numerous projections that look like hairs.

The clear, gelatinous fluid inside a cell.

Cell biologists have discovered that cells have a support structure.

Endoplasmic Reticulum

The cytoplasm suspends the cell's organelles. One particular organelle in a eukaryotic cell.

Longer projections that move with a whip like motion.

After proteins are made they are transferred to another organelle.

Organelles that contain digestive enzymes.

Are smaller, solid protein fibers.

Thin, hollow cylinders made of protein.

Membrane-bound organelles in plant and animal cells that transform energy for the cells.

Within the nucleus is a prominent organelle.

Chloroplast belongs to a group of plant organelles.

The sites where the cell produces proteins according to the direction of DNA.

Cell's have membrane-bound compartments.

Cell organisms that capture light energy and convert it to chemical energy.
