|
active Transport
|
Materials move from an area of lower concentration to an area of higher concentration
|
|
|
aerobic respiration
|
process that combines sugar (food) and oxygen in the presence of enzymes to make energy
|
|
|
anaerobic respiration
|
A respiration process that does not require oxygen. A small amount of energy is produced along with carbon dioxide and either alcohol or lactic acid
|
|
|
chlorophyll
|
The green pigment in chloroplasts
|
|
|
chloroplasts
|
The organelles involved in the manufacture of food (photosynthesis)
|
|
|
chromosomes
|
Long, threadlike structures located in the nucleus of the cell. They contain heredity information organized as genes.
|
|
|
cytoplasm
|
The watery cell fluid that contains the cell organelles
|
|
|
diffusion
|
A process by which cells absorb materials by means of passive transport, in which materials move from an area of higher concentration to an area of lower concentration.
|
|
|
endoplasmic reticulum
|
System of channels or canals for the transport of materials throughout the cell.
|
|
|
fermentation
|
Another name for anaerobic respiration
|
|
|
lysosome
|
Membrane-bounded sacs that contain digestive enzymes. Destroy damaged or old cell parts or cells in multi-cellular animals
|
|
|
mitochondria
|
Organelles involved in cellular respiration. The "power house' of the cell.
|
|
|
nuclear membrane
|
membrane that surrounds the nucleus
|
|
|
nucleolus
|
structure located in the nucleus that is involved in the production of ribosomes
|
|
|
nucleus
|
The nucleus is a large, round structure located inside the cytoplasm of the cell that controls cell activities
|
|
|
organelles
|
small structures located inside the cell
|
|
|
organs
|
A group of specialized tissues performing one main function
|
|
|
osmosis
|
A special kind of diffusion where water moves across a semipermeable membrane from an area of higher concentration to an area of lower concentration
|
|
|
photosynthesis
|
The process by which the green plant makes food
|
|
|
plasma membrane
|
AKA the cell membrane. It is a double-layered structure that surrounds the cell. It provides a boundary between the cell and its environment
|
|
|
ribosomes
|
Organelles that synthesize proteins
|
|
|
selectively permeable
|
A membrane that allows only certain substances to pass through it
|
|
|
systems
|
A group of organs that carry on one of the major body functions
|
|
|
tissues
|
Groups of similar cells performing the same function
|
|
|
vacuoles
|
Organelles that are located in the cytoplasm and are used by the cell for the storage of various materials including water, wastes, and food
|
|
|
endoplasmic reticulum
|
system of channels or canals that transport materials throughout the cell
|
|
|
Golgi Complex
|
synthesize, package and secrete cell products
|
|
|
centrioles
|
involved in cell division
|
|
|
chloroplasts
|
The site of photosynthesis. Innvolved in manufacture of food.
|
|
|
cell wall
|
Surrounds the cell membrane and its contents; gives the plant its shape
|
