Organelles Flashcards
An organism with cells that contain nuclei and other cell structures
Eukaryote
A tiny structure in the cytoplasm of a cell where proteins are made
Ribosomes
A type of organism that is made up of many cells
Multicellular
Observed the structure of a thin slice of cork using a compound microscope he built himself
Robert Hooke
Made his own lens. He observed water from a pond and found one-celled organisms. He also looked at scrapings from teeth when he could see tiny single called organisms
Anton van Leeuwenhoek
Concluded that all plants are made of cells
Matthias Schleiden
Concluded that all animals are made up of cells
Theodor Schwann
The process by which an organisms internal environment is kept stable in spite of changes in external environment
Homeostasis
Proposed that new cells are formed from existing ones
Rudolf Virchow
Protects the nucleus
Nuclear membrane
A tiny cell structure that carries out a specific function within the cell
Organelle
A type of organism that is made up of only one cell
Unicellular
Material in cells that contains DNA and carries genetic information
Chromatin
The outside boundary of the cell controls which substances can enter or leave the cell
Cell membrane
A rigid layer of nonliving material that protects the cell
Cell wall
The boss of all the cells that directs all cells activities
Nucleus
Contains a jel-like material and cell organelles
Cytoplasm
An organism that cannot make its own food
Heterotrophs
An organism whose cells lack energy left and some other cell structures
Prokaryote
An organism that makes its own food
Autotroph
All living things are composed of cells and cells are the basic unit of structure and function of living things all cells are produced from other cells this theory holds true for all living things no matter how big or small by learning about self and how they function you can learn about types of living things
Cell theory
I cell structure that forms a maze of passageways and which proteins and other materials Are carried from one part of the cell to another
Endoplasmic reticulum
Rod shaped cell structures that produce most of the energy needed to carry out the cells functions
Mitochondria
Receives proteins from ribosomes endoplasmic reticulum and send some back out
Golgi Body
A structure and the cells of plants and some other organisms that captures energy from the sunlight and uses it to produce food
Chloroplast
A green pigment found in chloroplasts of plants algae and some bacteria
Chlorophyll
Storage area for the cell
Vacuole
A small round cell structure that contains chemicals that break down large food particles into smaller ones
Lysosome
