What is the difference between Unicelular organisms and multicellular organisms.
Unicellular Organisms consist of one cell for example…human
while a multicellular organisms consist of more than two cells or example…ameba
How do Specializes cells share a division. Of labor and what types of organisms are they in
Specialized cells perform specific functions that benefit the entire organism Specialized cells are found in multicellular organisms.
3 statements that make up Cell theory
All living things are made of cells. Cells are composed of cells. Cells are the basic unit of structure and function in any living thing.
5 levels of organization in a human body and definitions from smallest to biggest.
1) Cell: The basic unit of structure and function in living things.
2) Tissue: A group of similar cells that perform a specific function.
3) Organ: A body structure that is composed of different kinds of tissues that work together.
4) Organ system: A group of organs that work together to perform a major function
5) Organism: Any living thing
The difference between an element and a compound.
An element is a pure substance that cannot be broken down into other substances by chemical or physical means.
A compound is a substance made of two or more elements chemically combined in a specific ratio, or proportion.
the 4 necessary organic compounds that a cell needs to survive.
1) Carbohydrates: provide energy
2) Lipids: Store energy
3) Proteins: repair cell parts
4) DNA: carries information or instructions that is needed to carrying the functions of life.
What is the difference between organic and Inorganic compounds.
An inorganic compound dose not contain carbon and An organic compound contains carbon.
The necessary inorganic compound that a cell needs to survive
Water
What is the difference between plant and animal cells.
Plant cells have a cell wall and have a bigger vacuole than animal cells and plant cells have chlorophyll which make food for the plants and turn the plant green. Wahl animal cells have a smaller vacuole and don’t have chlorophyll so in that case animals are not green and they have to find food and animal cells only have lysosomes because animals don’t make their own food.
The importance of water in cells
Because carrying substances in and out of cells
Water changes Temperature slowly
Helps cells take its shape
Helps dissolve cells
Takes part in many chemical reactions in cells
Cell wall
Protects plant cells
Ribosomes
lt produces proteins.
Mitochondria
converts energy in food molecules to energy the cell can use to carry out its functions.
Nucleus
contains the cell’s genetic material in the form of DNA and controls many of the cell’s activities.
Characteristics of all living things
1) to be able to grow and develop
2) to obtain and use energy
3) to be able reproduce
4) all living things are made of 1 or more cells
5) contain chemicals of life including DNA
6) undergo metabolism
