Cell Theory
Learning Target: I can develop and use a model to describe the function of a cell as a whole and ways
parts of cells contribute to the function.
Cell: smallest structural and functional unit of an organism (make up all living things).
Examples of things made of cells: flowers, skin, milk, hamburger, apples, sugar, blood, and saliva.
Examples of things NOT made of cells: proteins, rocks, DNA, calcium, sand, water, molecules,
chlorophyll, cell membrane, chromosomes, and atoms.
3 Parts of Cell Theory
1. All organisms are composed of one or more cells.
2. The cell is the basic unit of structure and organization in organisms.
3. All cells come from preexisting cells.
History
Leeuwenhoek – developed a more powerful microscope to discover bacteria.
Hooke – coined the phrase “cell” by comparing the cambers she saw on a
piece of cork to the rooms monks slept in (small area).
Schleiden – discovered all plants were made of cells (plant cells).
Schwann – discovered all animals were made of cells (animal cells).
Cell Organelles
Cell Part
Structure/Function
Cell Wall
A rigid structure that surrounds the cell membrane and provides support
to the cell.
Chloroplast
The organelle that uses the energy of sunlight to make food. (plant cell)
Cytoplasm
The fluid inside a cell.
Endoplasmic reticulum
The organelle that makes lipids, breaks down drugs and other
substances, and packages proteins for Golgi complex.
Golgi apparatus
The organelle that processes and transports protein and other materials
out of cell.
Lysosome
The organelle that digests food particles, wastes, cell parts, and foreign
invaders.
Mitochondria
Nucleus
The organelle that breaks down food molecules to make ATP.
The organelle that contains the cell’s DNA and is the control center of
the cell.
Cell membrane
A phospholipid layer that covers a cell’s surface; acts as a barrier
between the inside of a cell and the cell’s environment.
Large central vacuole
The organelle that stores water and other materials. (plant cell)
Small vacuoles
Ribosome
The organelle in an animal cell that stores food and nutrients.
The organelle in which amino acids are hooked together to make
proteins.
