These are the types of cells that a lack a nucleus.

What are

PROKARYOTIC cells?

100

In 1855, which scientist studied tissues and cells being generated by cellular division under a microscope?

Who was 

Rudolf Virchow?

This led to the THIRD part of Cell Theory.

100

The differences in behavioral or physical traits observed among individuals within a population of organisms.

What are 

variations?

100

I have a nucleus and many cells. I am a "producer" because I make my own food using the sun. Who am I?

PLANTS!

An organism that gets its energy from eating other organisms is a heterotroph, said Mr. Rogers.

Was he correct or incorrect? How do you know?

Correct, because if an organism that gets its energy from the Sun is an autotroph.

In 1677, which scientist? 

  • Developed a single lens microscope
  • Detected single celled organisms from pond water and saliva that he referred to as “animalcules” – later confirmed as bacteria and protozoa?

Who was

Antoine van Leeuwenhoek?

When a juniper tree can self-prune, directing limited water only to critical branches to survive, would this be considered an ADVANTAGE or DISADVANTAGE in a changing environment? 

Trees like junipers can self-prune which is an ADVANTAGE because it directs limited water only to critical branches to survive.

I have a nucleus. I am usually made of many cells, but I never make my own food. I often grow on logs or in the soil. Who am I?

FUNGI!

The presence of THIS cell structure will determine whether this cell is a prokaryote or eukaryote: 

What is 

THE NUCLEUS?

In 1665, which scientist:

  • Improved the design of the existing compound microscope
  • Observed a piece of cork, and to him, the cork looked as if it was made of pores or small compartments.
  • He called these pores “cells” because they reminded him of the cells in a monastery?


It was

ROBERT HOOKE!

Which variation would be a DISADVANTAGE to the survival of an organism as environments change?

A  A deer with an extra horn

B  A bird flying with a flock

C  A monarch butterfly with a damaged wing

D  A bison that joins a herd

The DISADVANTAGE would be 

C   A monarch butterfly with a damaged wing.

 I am complex and made of many cells. I have a nucleus to hold my DNA, but I cannot make my own food—I have to eat other things to survive. Who am I?

ANIMALS!

This part of a cell provides structural support and protection, particularly in plant cells and some prokaryotes.

What is a 

CELL WALL?

400

The three main components of cell theory are _____________________________, ____________________________________, and ___________________________.

What is

1. All organisms are made up of one or more cells.

 2. All cells come from pre-existing cells. 

3. Cells are the smallest functioning unit of life; the cell is the basic unit of life

Kangaroo rats burrow into the soil to escape surface heat and moisture loss.  This variation of this population would be an advantage in what type of weather issue?

a. flood

b. drought

c. extreme cold

This would be helpful in a

DROUGHT!

 I am a simple organism. I only have one cell and I don’t have a nucleus. Sometimes I make my own food, and sometimes I find it. Who am I?

BACTERIA or ARCHAEA

500

The presence of chloroplasts indicates a cell's ability to perform photosynthesis, a key process for THIS type of organism.

What are 

AUTOTROPHS?

500

In 1838, which TWO scientists?

  • Studied animal and plant cells respectively
  • Identified key differences between animal and plant cells
  • Put forth the cell theory, the idea that cells were the fundamental units of both plants and animals?

Who are

Theodore Schwann & Mattias Schleiden?

This led to the FIRST TWO principles of Cell Theory.

Peppered moths live on the trunks of trees. Pollution causes the trunks to darken over many years. 

Would light moths OR dark moths have a great advantage with this change AND how do you know?

The DARK moths would have a greater chance of COMPETING in this environment, giving them the ADVANTAGE to have offspring and pass on this variation.

I usually have a complex singular cell and have a nucleus. I sometimes make my food, and yet sometimes I find it. Who am I?
