Then, I could also look to see if the cells had chloroplasts or a cell wall to tell if it was a plant cell. Cell Structure and Functions; Cell- Number, Shape and Size; Cell Theory. 1 Cell Structure, Cell Function, and Biomolecules 1.1 Learning Goals, Motivation, and Standards 1.2 Group Interview Summaries 1.3 Links Edited by Peter Blodnik, Jessica Clark, Nicole Martinez, and Amanda Smith 1. Cells use energy *Why is the Cell Theory called a Theory? The basic structure of a cell, including the various organelles that make it up, can be linked back to what that cell does. All living cells arise from pre-existing cells by division. Cell Organelles: Structure: Functions. Present both in plant and animal cell. The cell wall and the cell membrane are the main components that function to provide support and structure to the organism. Outside of the nucleus is a fluid-like material called the cytoplasm that holds all the organelles. To observe the basic components of a plant cell: Peel an onion. The first step of cellular respiration, called glycolysis, occurs in the of all cells. Provides shape, p rotects the inner organelle of the cell and a cts as a selectively permeable membrane.

The cell function is to keep all of the functions of the body performing as intended. People also had many wrong ideas about living things on Earth. All living organisms are made of one or more cells, the cell is the smallest unit of life, and all new cells come from cells that already exist. Some organisms are made up of a single cell, like bacteria, while others are made up of trillions of cells.
