Organelles, Organelles, Parts of the Cell, Organelles
Mitochondria
"power plants" of the cell; sites of cellular respiration
Cell Theory
1. All living things are made of cells 2. Cells are the most basic unit of life 3. Cells come from other cells
cell membrane
A cell structure that controls which substances can enter or leave the cell.
Endoplasmic Reticulum
A cell structure that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another.
Cytoplasm
A jellylike fluid inside the cell in which the organelles are suspended
lysosome
A membrane bound organelle containing digestive enzymes that breakdown cellular waste. Removes "junk" from cells and old organelles
cell wall
A rigid structure that surrounds the cell membrane and provides support for plant cells
cell wall
A rigid structure that surrounds the cell membrane and provides support to the cell - usually plants, fungi algae, and some bacteria
Cell
Basic unit of life. All cell contain a cell membrane and DNA
nucleus
Brain of the cell, contains all the cell's DNA with coded instructions for making proteins and other molecules
Nucleus
Control center of the cell. Contains DNA.
chloroplast
In plant cells and algae: organelle that uses the sun's energy to produce food through photosynthesis.
In what organelle does cellular respiration take place
Mitochondria
Semipermeable
Only certain substances can pass through
Golgi apparatus
Organelle that packs and ships molecules
Mitochondria
Powerhouse of the cell, organelle that gives the cell energy
Golgi apparatus
Receives proteins & materials from the ER, packages them, & distributes them
Organelle
Specialized structure that performs important cellular functions within a eukaryotic cell
vacuole
Stores material such as water, salts, proteins and carbs
cytoplasm
The fluid material inside of a cell that supports the cell and its organelles
Name two storage organelles
Vacuoles and vesicles
flagella
a "whip-like" structure that helps some cells MOVE
Cytoplasm
a fluid, or gel-like substance, that fills the cell; the organelles and other particles float in it.
Homeostasis
a state of equilibrium; a cell keeping itself (and it's organism) happy, balanced, content
ribosome
assembles amino acids to create proteins
Things common to ALL CELLS
cell membrane ribosome Nucleus or (DNA) cytoplasm
cell membrane
flexible barrier around a cell; regulates what enters and leaves the cell
Vacuole
fluid-filled organelles that store materials such as food, water, sugar, minerals and waste products; MUCH larger in plant cells
Cell Wall
hard organelle just outside the cell membrane; gives the plant cell (and some prokaryotic cells) structure and support; protects the cell; contains pores which allow materials to pass to and from the cell membrane
Multicellular
having more than one cell
Unicellular
having only one cell
Golgi Apparatus (or Bodies)
modifies, sorts, and temporarily stores proteins
Chloroplast
organelle found in plant cells that captures the energy from sunlight and converts it into chemical energy
Chloroplast
organelle that converts solar energy to sugar; makes plants green because they contain chlorophyll; site of photosynthesis; found in plant cells (and some bacteria) only
Ribosomes
organelle that makes proteins. Located on the ER or in cytoplasm
Chloroplast is the key part in
photosynthesis
Cell Membrane
separates the cell from the surrounding environment and functions as a selective barrier for the import and export of materials.
cilia
short "hair-like" structures that help some cells MOVE and stick to other bacteria
Lysosome
small round structures that contain a strong digestive enzymes which, when released, can break down worn out organelles
Types of cells that have a cell wall
some prokaryotes and plant cells
Organelle
tiny specialized structures inside each cell that carry out a specific function.
Nucleus
where most of the genetic material (or DNA) of the cell is stored; only found in eukaryotes.
Ribosomes
where proteins are made in the cell
