Question

key questions

1. how did hooke’s work contribute to the cell theory?
2. what does it mean if a micrograph is “false - colored?”
3. what is the defining characteristic of eukaryotic cells? what types of organisms have eukaryotic cells?

Explanation:

1. Hooke was the first to use the term "cell". He observed cork under a microscope and saw small, box - like structures which he named cells. His work laid the ground - work for the cell theory by introducing the concept of the cell as a basic unit of life.
2. False - coloring a micrograph means adding artificial colors to an image produced by a microscope. This is done to enhance contrast, differentiate structures, and make it easier to visualize and analyze the sample.
3. The defining characteristic of eukaryotic cells is the presence of a true nucleus enclosed by a nuclear membrane. Organisms such as animals, plants, fungi, and protists have eukaryotic cells.

Answer:

1. Hooke introduced the term "cell" by observing cork under a microscope, laying the ground - work for cell theory.
2. It means adding artificial colors to enhance contrast and visualize structures in a micrograph.
3. Defining characteristic: presence of a true nucleus. Organisms: animals, plants, fungi, protists.
