100
The smallest units that carry out the activities of life in an organism
What are cells?
100
This directs all cell activities
What is the nucleus?
100
Materials enter and leave the nucleus through this
What is the nuclear envelope?
100
This is the gel-like substance in a cell that provides the environment for all other organelles.
What is the cytoplasm?
100
Proteins are made in these structures.
What are ribosomes?
200
The transportation system that moves materials around in the cell.
What is the endoplasmic reticulum?
200
These structures store food, water, and waste products in the cell.
What are vacuoles?
200
Found in the center of the nucleus.
What is the nucleolus?
200
This organelle generates energy in the cell.
What is the mitochondria?
200
Groups of similar tissues working together to perform the same job.
What are organs?
300
This enabled scientists to discover the cell in the 1600's.
What is the technology of microscopes?
300
These organelles help clean up the cell and remove waste.
What are lysosomes?
300
Protective structure found in plants, fungi, bacteria, and some protists but not in animal cells.
What is cell wall?
300
This endoplasmic reticulum contains ribosomes.
What is the rough ER?
300
The role of this organelle is to help a plant cell remain rigid and hold up heavy structures and also provides storage for the cell.
What is the central vacuole?
400
A stable internal environment
What is homeostasis?
400
Movement of water across a membrane.
What is osmosis?
400
Organelle that uses energy from the sun to produce food.
What are chloroplasts?
400
This structure packages and secretes substances in the cell, they are also called the "UPS of the cell.
What is the Golgi Bodies?
400
This allows certain materials to move into and out of the cell.
What is the cell membrane?
500
This material located within the nucleus that contains the genetic info.
What is chromatin?
500
This form of transport of materials across a membrane requires energy.
What is active transport?
500
Literally means 'little organ'.
What is organelle?
500
This is the pigment in chloroplasts that enable plants to absorb sunlight
What is chlorophyl?
500
The process by which molecules that cannot pass through a membrane alone and are 'helped' by proteins.
What is facilitated diffusion?
