Cells to Organisms Flashcards
Microscope
A microscope is a object that helps you to see smaller things
Single-celled organisms
An organism that has only one cell
Organism
A living animal or plant. They all have different shape and sizes.
Multicellular organisms
A organism that has more than one cell
Nucleus
The middle of a cell. Every cell has a nucleus including single-celled organisms and multi-cellular organisms.
Matter
Matter is the size of something
The smallest living things on earth are made of only one cell. These organisms are called _____________.
Single celled organisms
Name 4 single celled protists found in one drop of water.
Euglenas, diatoms, amoebas and paramecia
What type of protist is similar to plants and can make their own food?
Euglenas
Can single celled organisms make their own food?
No,not all single cells organisms can make their own food,because some of them have to move around to find food
Name two things all living things must be able to do to continue to live
They need food, and need to move wastes to survive
How does the single celled organism, amoeba move?
This micro organism forms false arms. These arms push the organism ahead
How does the single celled organism, paramecium move?
This micro organism has hair like external structures. These structures move back and forth to push the organism ahead
Name three ways that bacteria can be beneficial
1) feeds on parasites-2)keeps you clean
3) Bacteria helps create medicine-4)helps you digest food
5) bacteria helps decompose dead animals
6) bacteria helps in the soil
Cell

A group of organs
What are cells?

Where to find DNA
You can find DNA in the middle of a cell, the cell’s nucleus. DNA carries genetic information.
Protoplasm
Protoplasm is a complicated structure that is around the nucleus. Protoplasm has a double layer membrane that is always changing.
Organelle
A small structure in multi cellular organisms that carries out day–to-day cell operations.
