What are cell organelles?
Cell organelles are structures inside a cell which have specific jobs or functions to keep the cell healthy and alive.

In a many-celled organism, how are cells organized?
Cells make up tissues; tissues make up organs; organs make up systems that work together.

What is the name of a cell that does contain a nucleus?
Eukaryote

Which organelle is responsible for making proteins?
Ribosomes make proteins.

Why do cells in your body have different shapes?
Cells are specialized to perform different functions, so there shapes are very different.

On a microscope, what is the lens that you look through called?
It is called the ocular lens.

According to the Cell Theory, cells come from...
other cells.

Bacteria are made of what type of cells?
Prokaryotic cells

Name the function of the chloroplasts?
Chloroplasts capture the suns energy and change it into energy the plant can use (chemical energy).

Define an organ system.
An organ system is a group of different organs that work together to perform a major function for your body. An example is your cardiovasculary system.

How do you calculate the strenght or magnification of a light microscope?
Multiply the strength of the ocular lens by the strength of the objective lens to get total magnification.

Which two organelles are found in plant cells but not in animal cells?
Two organelles found in plant cells only are the chloroplasts and cell wall

Where is the genetic material stored in a bacterial cell?
The genetic material is found in the cytoplasm all throughout the bacterial cell.
500
Give the funcitons of these organelles: nucleus, endoplasmic reticulum, and golgi bodies.
The Nucleus controls the cells activities; The endoplasmic reticulum’s passageways carry proteins and other materials from one part of the cell to another; The Golgi bodies receive proteins and other newly formed materials from the endoplasmic reticulum, package them, and distribute them to other parts of the cell.
