Biology Flashcards
Specialisation in animal cells
As their body develops is becomes a specialised cell
When can plant cells differentiate
Able to differentiate all through their lives
What cells can animal cells differentiate into
Red blood cells
Muscle cells
Skin cells
What can plant cells differentiate into
All types of plant cells
Phloem cells
Xylem cells
Root hair cells
Exchanging materials
Exchange of many materials in the body happens through diffusion
where materials move from a higher concentration to a lower concentration
Evaluate the use of stem cells from embryos or from adult bone marrow for treating human diseases
Embryonic stem cells can differentiate into any cell type in the body
Adult stem cells can differentiate into a limited range of cell types
Tissue
Group of similar cells that work together to carry out a particular function
Muscular tissue
Contracts to move whatever it”s attached to
Glandular tissue
Makes and secretes chemicals such as enzymes and hormones
Epithelial tissue
Covers some parts of the body
Organ
Group of tissues working together to carry out a particular function
Where is amylase made
Salvary glands
Pancreas
Small intestine
Where is protease made
Stomach
Pancreas
Small intestine
Where is lipase found
Pancreas
Small intestine
Where is bile produced and stored
Produced - liver
Stored - gallbladder
Function of pancreas
Produces protease, amylase and lipase enzymes
Releases these into the small intestine
Function of liver
Where bile is produced
Alveoli
Tiny air sacs in the lungs surrounded by a network of blood capillaries
