Cell Biology Basics

Mitochondrion

• Cell organelle that converts the chemical energy stored in food into compounds that are more convenient for the cell to use

• Site of protein synthesis in the cell

• Structure that contains the cell's genetic material

• Organelle responsible for photosynthesis in plant cells

Animal Cell

• the smallest unit of life that has the basic organelles and may also have cilia or flagella to aid in movement

• a type of plant cell that contains chloroplasts

• a large structure that contains multiple organ systems

• a cell that is only found in multicellular organisms

Cell

• the smallest unit of life

• a type of tissue

• a group of organs

• a type of organism

Bacteria Cell

• eukaryotic, contains a nucleus, has membrane-bound organelles.

• prokaryotic, contains no nucleus, no membrane bound organelles.

• eukaryotic, contains no nucleus, has membrane-bound organelles.

• prokaryotic, contains a nucleus, has membrane-bound organelles.

Cytoplasm

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

• A rigid structure that provides support to the cell

• The control center of the cell that contains DNA

• A network of protein filaments that helps the cell maintain its shape

Plant Cell

• contains a cell wall, chloroplast and large vacuole

• contains a cell membrane, mitochondria and small vacuole

• contains a nucleus, ribosomes and lysosomes

• contains a cell wall, ribosomes and small vacuole

Cell Theory

• All living things are composed of cells, and cells are the basic units of structure and function in living things, and new cells are produced from existing cells.

• All living things are composed of tissues, and tissues are the basic units of structure and function in living things, and new tissues are produced from existing tissues.

• All living things are composed of organs, and organs are the basic units of structure and function in living things, and new organs are produced from existing organs.

• All living things are composed of molecules, and molecules are the basic units of structure and function in living things, and new molecules are produced from existing molecules.

Nuclear Membrane

• A highly-porous membrane that separates the nucleus from the cytoplasm

• A rigid structure that protects the cell from external damage

• A fluid-filled sac that stores nutrients and waste products

• A network of protein filaments that provides structural support to the cell

Chloroplast

• organelle found in cells of plants and some other organisms that captures the energy from sunlight and converts it into chemical energy

• a type of cell membrane that regulates the entry and exit of substances

• a structure that provides support and protection to plant cells

• a small organelle responsible for protein synthesis

Nucleus

• A part of the cell containing DNA and RNA and responsible for growth and reproduction

• The outer layer of the cell that protects it from the environment

• The structure that produces energy for the cell

• The part of the cell responsible for protein synthesis
