Aerobic respiration is the release of energy from food by a cell using oxygen

A bacteria cell is a tiny individual cell of bacterium

A cell membrane is a selectively permeable membrane enclosing the cell cytoplasm and controlling the entry and exit of materials

The cell wall supports the cell and prevents it from bursting; plant, fungal and bacteria cell walls all have different structures and chemical compositions

Cellulose is a structural carbohydrate which cell walls are composed of

Chloroplast is an organelle containing chlorophyll which is the main site of photosynthesis

Cytoplasm is a jelly-like liquid containing cell organelles, it is the main site of many chemical reactions

DNA (deoxyribonucleic acid) is a substance in chromosomes which carries the genetic code of an organism

A fungal cell is a tiny individual cell of fungus

A mitochondrion is an organelle which is the site of aerobic respiration and ATP production in cells

Multicellular is when something has many cells

A nucleus is an organelle which is the control centre of a cell and it contains the genetic information of an organism

And organelle is a membrane-bound compartment which has a specific function in animal, plant, and fungal cells

Photosynthesis is a process carried out by green plants in which they make their own food using light energy

A plasmid is a circular genetic material which is present in a bacteria cell, and is used in genetic engineering or modification

A protein is a substance composed of a chain of amino acids and containing the elements carbon, hydrogen, oxygen, and nitrogen

A ribosome is the site of protein synthesis

Ultra structure is fine structure and detail of a cell and it’s organelles revealed by an electron microscope

Uni-cellular is when something only has one cell

A vacuole is a membrane-bound sac containing cell sap in plant and fungal cells
