Biology Study - 1 Flashcards
What is a aerobic respiration?
Aerobic respiration is the release of energy from food by a cell using oxygen
What is a bacteria cell?
A bacteria cell is a tiny individual cell of bacterium
What is a cell membrane?
A cell membrane is a selectively permeable membrane enclosing the cell cytoplasm and controlling the entry and exit of materials
What does the cell wall do?
The cell wall supports the cell and prevents it from bursting; plant, fungal and bacteria cell walls all have different structures and chemical compositions
What is Cellulose?
Cellulose is a structural carbohydrate which cell walls are composed of
What is Chloroplast?
Chloroplast is an organelle containing chlorophyll which is the main site of photosynthesis
What is a Cytoplasm?
Cytoplasm is a jelly-like liquid containing cell organelles, it is the main site of many chemical reactions
What is DNA?
DNA (deoxyribonucleic acid) is a substance in chromosomes which carries the genetic code of an organism
What is a fungal cell?
A fungal cell is a tiny individual cell of fungus
What is a Mitochondrion?
A mitochondrion is an organelle which is the site of aerobic respiration and ATP production in cells
What does multicellular mean?
Multicellular is when something has many cells
What is a Nucleus?
A nucleus is an organelle which is the control centre of a cell and it contains the genetic information of an organism
What is an Organelle?
And organelle is a membrane-bound compartment which has a specific function in animal, plant, and fungal cells
What is Photosynthesis?
Photosynthesis is a process carried out by green plants in which they make their own food using light energy
What is a Plasmid?
A plasmid is a circular genetic material which is present in a bacteria cell, and is used in genetic engineering or modification
