The main scientists involved in the development of the cell theory and what each of them contributed

- Botanist Matthias Schleiden determined all plants were made of cells - Biologist Theodore Schwann determined all animals were made of cells

What are the 3 fundamental ideas that make up the cell theory?

1. The cell is the basic unit of all living things 2. Cells perform all the functions of living things 3.Cells come from the reproduction of existing cells

Golgi apparatus

A cell organelle that helps process and package proteins and lipid molecules, especially proteins destined to be exported from the cell

Cytoskeleton

A network of fibers that holds the cell together, helps the cell to keep its shape

Lysosomes

An organelle containing digestive enzymes and they are found in eukaryotic cells

Who studied pond water and was the first to see living organisms under the microscope?

Anton Wan Lee

The word cylo means

Cell

This structure serves the outer boundary of the eukaryotic cell

Cell membrane

Vacuole

Cell organelle that stores materials such as water, salts, proteins, and carbohydrates

Eukaryotic cells

Contain a nucleus and other organelles that are bound by membranes.

The wheel under the stage that adjust the amount of light is called the

Diaphragm

What part of the cell serves to process package and export proteins?

Golgi apparatus

Endolasmic Reticulum (Smooth)

Involved in making lipids and has no ribosomes on it

Tiny structures that carry out cell functions are collectively called

Organelles

Mitochondria

Powerhouse of the cell, organelle that is the site of ATP (energy) production

Cell Membrane

Protects, transports, and communicates for the cell, it surrounds the whole cell and lets nothing bad go inside -it is made up of phospholipid Bilayer

Who was the first person to see cells under the microscope and give them a name?

Robert Hooke

To focus a spectrum, it is best to start with which objective

Scanning

prokaryotic cell

Singular cell organism that does not have a nucleus or other membrane-bound organelles. -circular DNA that is loose in the cell

When, using the high power objective, you should not adjust the

coarse focus

The jelly like interior of the cell is called the

cytoplasm

What part of the cell serves as the intracellular highway?

endoplasmic reticulum

Where are ribosomes usually located in animal and plant cells?

endoplasmic reticulum

What part of the cell is responsible for breaking down and digesting things?

lysosomes

Endoplasmic Reticulum (Rough)

makes proteins and has ribosomes

Unlike eukaryotes, prokaryotes do not have

membrane bound nucleus

Which technology was essential for the development of the cell theory?

microscopes

Where is DNA found?

nucleus

Chloroplasts

organelles that capture the energy from sunlight and convert it into chemical energy in a process called photosynthesis solar———— chemical

What part of the cell makes proteins?

ribosomes
