All living things are composed of this

What are cells?

How new cells are produced

What is from existing cells?

Two parts of a eukaryotic cell

What are nucleus and cytoplasm?

Eukaryotic cells contain structures known as this.

What are organelles?

Prokaryotes do not have this.

What is a nucleus?

These are small particles of RNA and protein found throughout the cytoplasm.

What are ribosomes?

They are assembled on ribosomes.

What are proteins?

Where lipid components of the cell membrane are assembled, along with proteins and other materials exported from the cell.

What is endoplasmic reticulum?

It modifies, sorts and packages proteins and other materials from the ER for storage in the cell or for secretion outside the cell.

What is Golgi appratus?

A structure called this helps support the cell. It is a network of protein filaments that helps the cell maintain its shape.

What is cytoskeleton?

Little organs

What are Organelles?

Portion of the cell outside the nucleus

What is cytoplasm?

Contains nearly all of the cell’s DNA, coded instructions for making proteins and other important molecules.

What is nucleus?

It is dotted with thousands of tiny pores that allow materials to move in and out of the nucleus

What is Nuclear envelope?

The granular material you can see in the nucleus

What is chromatin?

Captures energy from sunlight and converts it into chemical energy

What are chloroplasts?

Acts as a cell clean up crew.

What are lysosomes?

Converts chemical energy in food into compounds the cell can use

What are mitochondrion?

Protein channels allow for this to happen by allowing certain molecules to cross the membrane.

What is facilitated diffusion?

Moving materials in a cell in the opposite direction against a concentration difference.

What is active transport?

stated that cells only arise from pre-existing cells

Who is Virchow ?

The combined work of Schleiden, Schwann, & Virchow

What is the cell theory?

Anton Von Leeuwenhoek

Who made the first hand-held microscope?

made an improved microscope and viewed thin slices of cork viewing plant cell walls

Who is Robert Hooke?

Robert Hooke named this.

What is the cell?

The powerhouse of the cell

What is mitochondrion?
