Science Chapter 3 Section 3 Test
A group of cells working together to preform a specific function is an tissue
...
An Prokaryote is an organism whose cells have eukaryote
...
An cell is the most basic unite of all living things
...
Only plant cells have an Cell Wall
...
Ribosomes and mitochondria and types of organelles
...
The job that an organ does is the function of that organ
...
Which of the following statements is part of the cell theory
All cells come from other cells
Explain how the structure and function of an organism's parts are related give an example
An example alveoli are tiny sacks in the lungs that hold gases alveoli are made of membrane that enables oxygen and carbon dioxide to pass in and out of the blood
Explain why most cells are small
Because they are limited by cell surface to volume ratio
Explain ho the structure and function of an organism's parts are related give an example
Cells join together to form tissue which go together to make organs which go together to make and organ system and lets the animal breath pump blood and more such as the ER and the Golgi complex which both work together to get the materials to the cells in and organism to let the cell survive
What are the structure and function of the cytoskeleton in a cell
Is a web of protein and is made of protein and is made of stringy fibers and it keeps the cell membrane from collapsing
Which letter identifies the structure that digests food particles and foreign invaders
Letter b
Which letter identifies the structure that makes proteins, lipids, and other materials and that contains tubes and passageways that enable substances to move to move to different places in the cell
Letter c
The benefits of being multicellular include
Longer life, larger size, and specialized cells
One of your classmates states a hypothesis that all organisms must have organ systems is your classmate's hypothesis valid explain your answer
No because most single celled organisms do not have organs because they are not complex enough and most multicellular organisms have organs which gives them organ systems
Describe the four levels of organization in living things
So a bunch of cells go together and form a tissue and then a bunch of tissue goes together to form an organ and then a bunch of organs go together to form an organ system
Compare and contrast the function of the endoplasmic reticulum and the Golgi complex
The ER sends material to the Golgi complex which sends the materials to other cells and so the two cells work together to keep other cells alive
Scientists think that millions of years ago the surface of the Earth was very hot and that the atmosphere contained a lot of methane in your opinion which type of organism a eubacterium or an archebacteria is older form of life explain your reasoning
The archabacteria because they are a heat loving organism and this climate would be favorable to them because it would have been very hot and this would make it a perfect place for the archaebacteria to live
Name two functions of a cell membrane
To protect you from sicknesses and also contains lipids
What would happen if all of your ribosomes in your cells disappeared
You would die because your cells need protein and with out in they would al die and then you would to
Two types of organisms whose cells do not have a nucleus
Eubacteria and archaebacteria
Which of the following best describes an organ
A group of tissues that work together to preform a specific job
What is the name of the structure identified by letter a
The mitochondria
In a eukaryotic cells which organelle contains DNA
The nucleus
The surface area-to-volume ratio of a cell limits
The size of the cell
What is the difference between the structure of an organ and the function of the organ
The structure is how it is built and looks and the function is what it is doing and what it does
