The Cell Theory is based on two observations. That all living things are made of cells and that all cells come from other cells. Which of these observations was made first?

van Leeuwenhoek called the organisms he viewed in his microscope “little animals” and described parts like legs, fins, and heads. Later studies would show that these organisms have a nucleus. What kind of cells did he likely view?

Which of the following organelles would you expect to find in a prokaryotic cell?

Which of the following pairs does NOT match an organelle with its function in cells?

While both prokaryotes and eukaryotes have DNA, in prokaryotes DNA is arranged in a circle, whereas in eukaryotes DNA is arranged in linear strands.

Because they have the same DNA and come from the same single cell, all of the cells in a human look the same.

Macrophages are cells in the human immune system whose job it is to take in and then break down potentially harmful materials like germs and cancer cells. Which organelle below would you expect to find in abundance in macrophages?

Muscle cells have special fibers that use ATP to slide across each other to allow muscle contraction and, thereby, movement. Which organelle below would you expect to find in abundance in muscle cells.

Prokaryotic cells divide by:

Prokaryotic cells include _______ and ________.

All organisms are made of more than one cell.

Cell theory states that all organisms are made of one or more cells, all the life functions of organisms occur within cells, and all cells come from already existing cells.

Robert Hooke was the first person to observe cells. He observed these cells in ____

a single-celled organism that lacks a nucleus

The cytoplasm is generally considered to have two parts, one contained within this membrane system and the other, the cytoplasmic matrix proper

_____is a genus of bacteria that lack a cell wall around their cell membranes.

A____ is a submicroscopic infectious agent that replicates only inside the living cells of an organism.

a “virus-like”, they consist only of a short strand of circular RNA capable of self-replication. small, single-stranded, that despite their lack of protein-coding capacity, can infect higher plants and, in many cases, induce specific diseases.

This constitutes the true internal milieu of the cell and contains all the principal structures involved in cell shape and movement, protein synthesis and metabolic activity.

Outside a living host cell viruses are inactive and may be even crystallized.
