Science Flashcards 2012

Front 1

organelle

Back 1

tiny cell structures that carry out specific functions

Front 2

cell wall

Back 2

A rigid layer of nonliving material that surrounds the cells plants and some other organisms

Front 3

cell membrane

Back 3

This organelle controls what substances come into and out of a cell

Front 4

nucleus

Back 4

The cell's control center, directing all of the cell's activities

Front 5

cytoplasm

Back 5

This organelle includes a gel-like fluid in which organelles are found

Front 6

mitochondria

Back 6

"Powerhouses" of the cell; they convert energy in food molecules to energy the cell can use to carry out its functions

Front 7

endoplasmic reticulum

Back 7

The passageways of this organelle carry proteins and other materials from one part of the cell to another

Front 8

ribosome

Back 8

They function as factories to produce proteins

Front 9

Golgi body

Back 9

In an animal cell, they receive materials from the endoplasmic reticulum and send them to other parts of the cell, they also release materials outside the cell

Front 10

chloroplast

Back 10

In the plant cell, these organelles capture energy from sunlight and use it to produce food for the cell.

Front 11

vacuole

Back 11

A sac containing water, food, waste products, and other materials

Front 12

lysosome

Back 12

Small organelles which contain chemicals that break down food particles and worn-out cell parts; cleans out the cells

Front 13

Nuclear envelope

Back 13

This organelle protects the nucleus. Materials pass in and out of the nucleus through pores in this organelle.

Front 14

chromatin

Back 14

It contains genetic material, the instructions for directing the cell's function

Front 15

Nucleolus

Back 15

The organelle where ribosomes are made
