Cell Organelles Study Set

Cell Wall

A strong layer around the cell membrane in plants, algae, and some bacteria

Cell membrane

a thin flexible outer layer that protects and surrounds

the cell and REGULATES what enters and leaves the cell

Nucleus

Control center inside a cell contains the cell's genetic

DNA material and controls the cell's activities

Nucleolus

Small region in the nucleus where the assembly of ribosomes begins.

ribosomes

Small particles in the cell where PROTEINS made of

RNA and Protein are assembled

Nuclear envelope (nuclear membrane)

double-membrane layer that surrounds the nucleus of a cell

Nuclear pore

a tiny hole in the membrane that surrounds the nucleus of a cell and allows material to move in and out of the nucleus "mini doorway"

chromosomes (chromatin)

a threadlike structure in the nucleus that contains the genetic information passed from one generation to the next.

Golgi Apparatus

a stack of membranes in the cell in which enzymes attach carbohydrates and lipids to proteins

Mitochondria

releases energy. Produces ATP using energy stored in

food molecules

Cytoskeleton

a network of protein filaments to help the cell maintain its shape and help the cell with movement

Smooth Endoplasmic Reticulum (Smooth ER)

package proteins to be used in the cell when needed

Rough Endoplasmic Reticulum (Rough ER)

package proteins to be used in the cell when needed

Lysosome

filled with digestive enzymes that surround and break down worn out cell parts

Flagella

a "whip-like" structure that helps some cells MOVE

Cilia

short "hair-like" structures that help some cells MOVE

Chloroplast

uses energy from the sunlight to make energy-rich food molecules by photosynthesis

Vacuole

STORES

water + salt + proteins + carbohydrates
