General Biology 7-2

Front 1

ribosomes

Back 1

organelle responsible for production of proteins

Front 2

nucleolus

Back 2

small, dense region inside the nucleus where the assembly of ribosomes begins

Front 3

golgi apparatus

Back 3

stack of membranes in the cell where enzymes attach carbohydrates & lipids to proteins

Front 4

chromosomes

Back 4

thread-like structure within the nuclesus containing the genetic information that is passed from one generation of cells to the next

Front 5

nuclear membrane

Back 5

double-membrane layer that surrounds the nucleus

Front 6

microtubules

Back 6

hollow tubes of protein that help retain cell shape & aid in organelle movement

Front 7

chloroplasts

Back 7

organelles found in PLANTS that use energy from the sun to make food in the process of photosynthesis

Front 8

chromatin

Back 8

granular material visible within the nucleus that consists of DNA tightly coiled around proteins

Front 9

cytoskeleton

Back 9

network of protein filaments that help the cell maintain its shape

Front 10

endoplasmic reticulum (e.r.)

Back 10

organelle in which components of the cell membrane are assembled

Front 11

mitochondria

Back 11

"powerhouses", organelles that use energy from food to make high-energy conpounds used by the cell for growth, development & movement

Front 12

lysosomes

Back 12

small organelles that break down larger particles, including old cells, into smaller particles

Front 13

vacuole

Back 13

structure that stores materials such as water, salts, proteins, and carbohydrates
