Cell Structure Flashcards
(24 cards)
what are three components of plant cells that animal cells do not have?
- cell walls
- chloroplasts
- vacuoles
draw and label a diagram of
1) an animal cell
2) a plant cell
[check using notes or online resources]
what is the function of a cell membrane?
controls passage of substances into and out of cell
what is the function of a nucleus?
controls the cell, contains DNA
what is the function of cytoplasm?
contains all components of cell including enzymes
what is the function of mitochondria?
release energy for respiration
~the powerhouse of the cell~
what are the functions of chloroplasts?
to carry out photosynthesis
what is the function of a vacuole?
contains cell sap
what is the function of a cell wall
encloses the cell and strengthens cell structure (made of cellulose)
what are the functions of ribosomes?
to make proteins
describe an organelle
a cell structure that is specialised to carry out a particular function or job
describe a cell
the basic structural and functional unit of a living organism
describe a tissue
group of cells with similar structures, working together to perform a shared function
describe an organ
substance made up of a group of tissues, working together to perform a specific function
describe an organ system
group of organs with related functions, working together to perform body functions
place the following human structures in order from smallest to largest:
- liver
- red blood cell
- eye
- white blood cell
- kidney
(smallest - largest)
- red blood cell
- white blood cell
- eye
- kidney
- liver
name four body systems
- circulatory
- respiratory
- excretory
- digestive
- nervous
- skeletal

list four single celled organisms
[bonus: draw two of them]
- bacteria
- yeast

- englena
list two examples of organisms with few cells
- volvox
- spirogyra
list four multicellular organisms
- humans
- millipedes
- starfish
- oak trees
- dogs
- chickens
- sunflowers
etc
list three types of tissue
- epithelium
- muscle tissue
- adipose tissue
list three organs
- intestines
- heart
- liver
list the function of a muscle cell and how it is adapted to suit this function
- cause movement
elongated in shape / have fibres which slide into each other / contain filaments of muscle proteins / have lots of mitochondria
list the function of ciliated epithelium and how they are adapted to suit this function
- lining the nose and windpipe
flattened shape / interlocking edges / cilia
