Cards in this deck (20)
- 1What are the building blocks of life?Cells and DNA
- 2What are cells?Cells are the basic building blocks of all living things. The human body is composed of trillions of cells. They provide structure for the body, take in nutrients from food, convert those nutrients into energy, and carry out specialized functions.
- 3What is the cell theory?Cell theory is a scientific theory which describes the properties of cells. These cells are the basic unit of structure in all organisms and also the basic unit of reproduction.
- 4What are organelles?Organelles are small, specialized structures in cells which operate like organs by carrying out specific tasks.
- 5What are mitochondria?Mitochondria are known as the powerhouses of the cell. They are organelles that act like a digestive system which takes in nutrients, breaks them down, and creates energy rich molecules for the cell.
- 6What are lysosomes?Organelles that get rid of wastes for cells.
- 7What is endoplasmic reticulum?Pathways along in which materials move through a cell.
- 8Diagram of an animal cell
- 9What are ribosomes?Structures that produce protien.
- 10What is chloroplast?An organelle within a cell where photosynthesis takes place.

- 12What is photosynthesis?Photosynthesis is the process by which plants make their own food.
- 13Diagram of fungi cell
- 14What are unicellular organisms?A unicellular organism, also known as a single-celled organism, is an organism that consists of only one cell, unlike a multicellular organism that consists of more than one cell.

- 16What are protists?Any of various one-celled organisms, classified in the kingdom Protista.
- 17What is mitosis?Mitosis is a process where a single cell divides into two identical daughter cells.
- 18What is cancer?A disease caused by the uncontrolled growth of cells.
