Cell Theory & Cells
This invention allowed scientists to first observe cells.
➡️ What is the microscope?
Cells that do NOT have a nucleus.
➡️ What are prokaryotic cells?
Differences in traits among individuals in a population.
➡️ What is variation?
Organisms made of only one cell.
➡️ What are unicellular organisms?
characteristics is true of all organisms?
Made of cells
This scientist first observed cork and named the structures “cells.”
➡️ Who is Robert Hooke?
Cells that DO have a nucleus.
➡️ What are eukaryotic cells?
A trait that helps an organism survive better in its environment.
➡️ What is an advantageous trait (adaptation)?
Organisms made of many cells.
➡️ What are multicellular organisms?
True or False: Heterotrophs can make their own food.
False
This part of cell theory states that all living things are made of these.
➡️ What are cells?
This type of organism is usually simple and always unicellular.
➡️ What is a prokaryote?
These organisms make their own food (like plants).
➡️ What are autotrophs?
These organisms make their own food (like plants).
➡️ What are autotrophs?
Would a bird that eats hard seeds need a big, strong beak or a small, weak beak.
Strong beak
This part of cell theory explains that cells come from this source.
➡️ What are pre-existing cells?
This type of cell contains membrane-bound organelles.
➡️ What is a eukaryotic cell?
If the environment changes, populations must do this to survive.
➡️ What is adapt?
These organisms must consume other organisms for energy.
➡️ What are heterotrophs?
If a white peppered moth and a black peppered moth sit on a black tree. Which moth is more likely to survive?
Black moth
This describes the role of cells as the smallest unit that performs life functions.
➡️ What is the basic unit of structure and function?
Bacteria are an example of this type of cell.
➡️ What are prokaryotic cells?
Over time, helpful variations become more common in a population through this process.
➡️ What is natural selection?
This is a key difference between unicellular and multicellular organisms.
➡️ What is number of cells / specialization of cells?
Why would an animal make multiple offspring?
To increase chances of survival
