Cell Organelles | TGHS Biology Honors G9 25-26

Cell Wall

A strong layer around the cell membrane made of cellulose in plants, algae, and some bacteria.

Cell Membrane

A thin flexible outer layer that protects, surrounds, and enclosed all the organelles of the cell and regulates what enters and leaves the cell.

Nucleus

Control center inside the cell. Contains the genetic/DNA material of the cell and control the cell’s activities.

Nucleolus

A small region in the nucleus where the assembly of ribosome begin.

Ribosomes

Small particles in the cell where proteins are made of RNA and protein.

Nuclear Envelope

Double membrane layer that surrounds the nucleas of a cell.

Nuclear Pores

Tiny holes in the membrane that surrounds the nucleus of a cell and allows materials to move in and out of the nucleus.

Chromosomes

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 which attach carbohydrates and lipids to proteins.

Lyosomes

Organelles that digest and break down old organelles and waste.

Flagella

A whip like tail structures to help some cells move.

Cilla

The outer hair lick structure some cells hace surrounding them that helps with movement.

Chloroplast

Uses energy from the sunlight to make food molecules through photosynthesis.

Vacuole

An organelle that stores water, salt, proteins and carbohydrates.

Mitochondria

Releases energy and produces ATP using stored energy inside of food molecules.

Cytoskeleton

A network of protein filaments to help mantain a cell’s shape and help in its movement.

Smooth ER

Responsible for the production of lipids, controls calcium levels in muscles as well as detoxifying poison, alcohol and drugs.

Rough ER

Responsible for the packaging of proteins for usage by the cell.

Centriole

Produce cilia during interphase and the aster and the spindle during cell division.

Eukaryotic Cells

Cells with a nucleas.

Prokaryotic Cells

Cells without a nucleas.
