Cells - Unit Test

Terms in this set (29)

Mitochondria
The 'Powerhouse' of the cell; converts glucose into energy.
Nucleus
The 'Command Center' of the cell; directs cell activities.
Chloroplast
Unique to plant cells. Site of photosynthesis.
Cell Membrane
Protective layer in plant AND animal cells that controls what moves in and out of the cell.
Ribosome
Makes proteins
Smooth Endoplasmic Reticulum (ER)
Transport system within the cell. Lipids are produced here.
Rough Endoplasmic Reticulum (ER)
Contains ribosomes. Helps with transport within the cell.
Golgi Apparatus
Prepares and packages proteins.
Cell Wall
Additional outer layer in plant cells. Provides support and protection.
Cytoplasm
The gel-like material that holds organelles in place and gives the cell shape.
Lysosome
Breaks down and recycles food, materials and old cell parts.
Nucleolus
Make ribosomes. Found within the nucleus.
Central Vacuole
Stores food, water, and waste for plant cells
Vesicle
Works to help move materials into and out of the cell during endocytosis and exocytosis.
Prokaryotic Cell
Simple, basic type of cell that lacks membrane-bound organelles.
Eukaryotic Cell
Plant and animal cells are examples of this type of cell. Highly organized with membrane-bound organelles.
Cell Theory
1. All living things are made of one or more cells
2. Cells come from pre-existing cells
3. Cells are the smallest unit of life
Passive Transport
Movement from HIGH to LOW concentrations. Does not use energy.
Active Transport
Movement from LOW to HIGH concentrations. Requires energy use.
Osmosis
The diffusion of water across a membrane.
Diffusion
The passive process of particles moving from HIGH to LOW concentration.
Facilitated Diffusion
Using transport proteins to move large or charged molecules across a membrane without the use of energy.
Endocytosis
The cell takes in a substance by surrounding it with the cell membrane.
Exocytosis
The cell's vesicles release their contents outside the cell.
Photosynthesis
The process of turning water, carbon dioxide, and light energy into glucose and oxygen.
Cellular Respiration
The process of turning glucose and oxygen into ATP, carbon dioxide and water.
Fermentation
Similar to Cellular Respiration but happens without oxygen.
Carbon Dioxide + Water + Light Energy => Glucose + Oxygen
Photosynthesis
Glucose + Oxygen => Carbon Dioxide + Water + ATP
Cellular Respiration
