Organelles (1)
This organelle processes and transports proteins and other materials out of the cell
Golgi Complex
A system of membranes that is found in a cell's cytoplasm and that assists in the production, processing, and transport of proteins and in the production of lipids
Endoplasmic Reticulum
An organism made up of cells that have a nucleus enclosed by a membrane; Includes protists, animals, plants, and fungi but not archaea and bacteria
Eukaryote
A fluid like substance enclosed by the cell membrane that surrounds the organelles of a cell with the exception of the nucleus
Cytoplasm
What was the original name for bacteria?
Animalcules
This organelle digests food particles, wastes, cell parts, and foreign invaders
Lysosome
A cell organelle composed of RNA and protein; the site of protein synthesis
Ribosome
A single-celled organism that does not have a nucleus or membrane-bound organelles; examples are archaea and bacteria
Prokaryote
A group of similar cells that perform a common function
Tissue
Which scientist came up with the word "Animalcules"?
1. Anton von Leeuwenhoek
2. Robert Brown
3. Theodor Schwann
Anton von Leeuwenhoek
This organelle stores water and other materials
Large central vacuole
In a eukaryotic cell, a membrane-bound organelle that contains the cell's DNA and that has a role in the processes such as growth, metabolism, and reproduction
Nucleus
A phospholipid layer that covers a cell's surface and acts as a barrier between the inside of a cell and the cell's environment
Cell Membrane
A collection of tissues that carry out a specialized function of the body
Organ
Which two scientist wrote the first two statements of the cell theory?
1. Robert Brown and Robert Hooke
2. Mattias Schleiden and Theodor Schwann
3. Hans and Zacharias Janssen
Mattias Schleiden and Theodor Schwann
A plastid that contains high amounts of chlorophyll and where photosynthesis takes place
Chloroplast
Helps a cell keep its shape and helps it move
Cytoskeleton
The smallest functional and structural unit of all living organisms; usually consists of a nucleus, cytoplasm, and a membrane
Cell
A group of organs that work together to perform body functions
Organ System
Who was the first to identify cells?
1. Mattias Schleiden
2. Robert Brown
3. Robert Hooke
Robert Hooke
Known as the "powerhouses" of cells because they produce most of the chemical energy needed to power the cell's biochemical reactions.
Mitochondria
A small sac that surrounds material to be moved
Vesicle
A rigid structure that surrounds the cell membrane and provides support to the cell
Cell Wall
A living thing; anything that can carry out life processes independently
Organism
What are the three statements of the cell theory?
1. All organisms are made of one of more cells
2. The cell is the basic unit of all living things
3. All cells are produced by existing cells
