Question

table 1: development of the cell theory shows some important information that they have gathered.

table 1: development of cell theory

scientist	discovery
antonie van leeuwenhoek	one - celled organisms living in pond water and in his mouth
matthais schleiden	all plants are made of cells
theodor schwann	all animals are made of cells
rudolph virchow	new cells come from preexisting cells

which statements are supported by these discoveries? select two.

• an elephant is too big to be made of microscopic cells.
• each cell in a dog’s body came from another cell.
• a tomato plant and a sunflower plant are both made of cells.
• all organisms are made of many cells.
• all cells are box - shaped.

Explanation:

1. Analyze "Each cell in a dog’s body came from another cell": Rudolph Virchow discovered new cells come from preexisting cells. A dog is an animal, so its cells follow this, so this statement is supported.
2. Analyze "A tomato plant and a sunflower plant are both made of cells": Matthias Schleiden found all plants are made of cells. Tomato and sunflower are plants, so this is supported.
3. "An elephant is too big to be made of microscopic cells": Theodor Schwann said all animals are made of cells, so elephants (animals) are made of cells, this is wrong.
4. "All organisms are made of many cells": Antonie van Leeuwenhoek found one - celled organisms, so not all organisms have many cells, this is wrong.
5. "All cells are box - shaped": Robert Hooke saw box - shaped cells in cork, but other cells (like those seen by Leeuwenhoek) aren't box - shaped, this is wrong.

Answer:

• Each cell in a dog’s body came from another cell.
• A tomato plant and a sunflower plant are both made of cells.
