Cell biology, Diffusion, Tissues and Organs Flashcards
What types of cells are classed as eukaryotic cells?
Plant and animal cells
What things can you find in eukaryotic cells?
Cytoplasm, nucleus, cell membrane, ribosome and mitochondria
What three extra things do plant cells have?
Permanent vacuole, cell wall and chloroplast
What is the difference between differentiation in plant cells vs. animal cells?
In animal cells differentiation only occurs in the early stages of life whereas with plant cells it’s throughout the entire life cycle.
Name an example of a prokaryotic cell?
A bacteria cell
What can you find in prokaryotic cells?
Cell membrane, bacterial DNA, cell wall, plasmid, cytoplasm
What are the different types of specialised animal cells?
Nerve cells, sperm cells and muscle cells
What are the different types of specialised plant cells?
Root hair cells, xylem cells and phloem cells
What is diffusion?
Movement of particles in a solution or gas from a higher to a lower concentration
How can you tell if the rate of diffusion is slow or fast?
The greater the difference in concentration the faster the rate of diffusion
What are the names of the adaptations of diffusion for these organs/organisms:
a) Small intestine
b) Lungs
c) Gills (in fish)
d) Roots
e) Leaves
a) Villi
b) Alveoli
c) Gill filaments and lamella
d) Root hair cells
e) Large surface area and thin leaves
What is the job of the digestive system?
To digest and absorb food
What organs play a part in the digestive system and in what order?
Mouth, oesophagus, liver, stomach, gall bladder, pancreas, small intestine, large intestine and anus
What health problems can occur because of a poor diet?
Obesity, cardiovascular disease and type 2 diabetes
What are the definitions of these systems in your body:
a) Cells
b) Tissues
c) Organs
d) Organ systems
a) The basic building blocks of all living organisms
b) A group of cells with a similar structure and function
c) The working together of tissues to perform a specific function
d) Organs working together to form systems, which work together to form organisms
