Cellular organelles

Nucleus

A part of the cell containing DNA and RNA and responsible for growth and reproduction and the control center of the cell.

Nucleolus

Makes ribosome parts

Plasma or cell membrane

Acts as a barrier between the inside and outside of the cell, materials enter or exit through it.

Mitochondria

Powerhouse of the cell, organelle that is the site of ATP (energy) production

Ribosomes

Makes proteins

Endoplasmic Reticulum

A cell structure that forms a maze of passageways in which proteins and other materials are carried from one part of the cell to another.

Golgi apparatus

A system of membranes that modifies and packages proteins for export by the cell

Lysosomes

Uses chemicals to break down food and worn out cell parts.

Centrioles

a minute cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division.

Chromosomes

Genetic material composed of condensed DNA and proteins that form during eukaryotic cell division

Cytoplasm

A jellylike fluid inside the cell in which the organelles are suspended

Chromatin

threadlike structures made of DNA molecules that contain the genes that will condense to form chromosomes

Vacuole

Cell organelle that stores materials such as water, salts, proteins, and carbohydrates

central vacuole

When they are full of water, the turgor pressure keeps the plant's stems and leaves firm. When water is lost, the stems and leaves become droopy

Chloroplast

absorb light energy which is used in photosynthesis. They also contain chlorophyll, which gives leaves their green colour

Cell theory: all living things are....

made up of one or more cells

Cell Theory: The cell is...

simplest unit that can carry out all life processes

Cell theory: All cells come from....

pre-existing cells

Prokayote

A unicellular organism that lacks a nucleus and membrane bound organelles

Eukaryotes

Organisms whose cells have a nucleus and membrane bound organelles.

Organelle

A tiny cell structure that carries out a specific function within the cell

cell wall

A rigid structure that surrounds the cell membrane and provides support to the cell

centrioles

a minute cylindrical organelle near the nucleus in animal cells, occurring in pairs and involved in the development of spindle fibers in cell division.
