This type of organism has only one cell that performs all of its life functions.
What is unicellular?
When examining cell models, you will find these two organelles in a plant cell, but not an animal cell.
What are the cell wall and the chloroplast?
This characteristic is the best way to tell the difference between living and nonliving things.
This organelle contains genetic information and instructs the cell activities.
What is the nucleus?
Cell theory states that all living things are made of this number of cells.
What is one or more?
A cell membrane is a characteristic shared by these two main classifications of cells.
What are prokaryotic and eukaryotic?
This cell organelle's function can be compared to the front door and walls of a school.
What is the cell membrane?
This term is used to refer to any living thing.
What is an organism?
This organelle is most like a power plant, creating energy that the cell needs to function.
What are the mitochondria?
Cell theory states that all cells come from this.
What are existing cells?
This type of organism has many cells that each do a different job.
What is multicellular?
These four features can be found in both prokaryotic and eukaryotic cells.
What are the cell membrane, DNA, cytoplasm, and ribosomes?
When observing pond water with a microscope, this trait is the best way to tell if an object is living.
Is it made of cells?
This liquid material can be found inside all cells, filling the spaces between organelles.
What is cytoplasm?
Cell theory states that these small objects are the smallest unit of life.
What are cells?
This type of cell is much smaller than other cells and contains no membrane-bound organelles.
What is prokaryotic?
This green organelle is found in plant cells, but not animal cells.
What is a chloroplast?
This category of cell contains membrane-bound organelles and is larger in size.
What is Eukaryotic?
This organelle is responsible for making proteins in a cell.
What is a ribosome?
This British scientist is credited with improving the microscope and naming "cells".
Who is Robert Hooke?
All multicellular organisms fall into this category of cell.
What is Eukaryotic?
This instrument can be used to increase the scale of a sample you wish to view.
What is a microscope?
This cell process allows multicellular organisms to repair themselves and unicellular organisms to reproduce.
What is cell division?
This formidable organelle is too tough to be found in an animal cell.
What is a cell wall?
Antonie van Leeuwenhoek discovered bacteria while looking at samples of this under a microscope.
What are teeth scrapings?
