Question

robert hooke observed cork tissue from a plant using a microscope and saw small, honeycomb - like structures, as shown in the image (labeled cork tissue). what contribution did hooke make to biology based on his observations? options: 1. he stated that every living thing is made up of more than one cell. 2. he stated that all cells come from preexisting cells. 3. he named the small structures organelles. 4. he named the small structures cells.

Explanation:

• Option 1: Robert Hooke observed cork tissue and named the small honeycomb - like structures he saw "cells". The statement "He stated that every living thing is made up of more than one cell" is incorrect as Hooke's observations were on dead cork cells and he didn't make this claim about all living things.
• Option 2: The idea that all cells come from pre - existing cells was proposed by Rudolf Virchow, not Robert Hooke.
• Option 3: Organelles were not named by Hooke; his contribution was naming the basic unit (the cell) from his cork observations.
• Option 4: Robert Hooke, upon observing the cork tissue under the microscope, named the small structures he saw "cells". This is his major contribution to biology in terms of cell discovery and nomenclature.

Answer:

He named the small structures cells.
