Each question in this quiz is timed.
What do most cells have (plant, algal and animal)?
A nucleus
Cytoplasm
A cell membrane
A cell wall
A permanent vacuole
Mitochondria
Ribosomes
Chloroplasts
Flagella
What features do ONLY plant and algal cells have?
What controls the cells activities?
The nucleus
The cell membrane
The mitochondria
The ribosomes
The cytoplasm is where many chemical reactions take place.
What controls the movement of materials in and out of the cell?
The flagella
What function do the mitochondria serve?
They respire and release energy
They move the cell
Protein synthesis occurs here
What happens in the ribosomes?
They control the cells activities
How are bacteria cells specialised?
Flagella enable the cells to move
A slime capsule which helps the cell stick to surfaces and protect it
Plasmids which carry extra genetic information
Many mitochondria to provide energy for movement
A nucleus to hold the genetic information
Red blood cells are specialised by...
Having no nucleus
Containing haemoglobin
Having a large surface area
Having no cell wall
Containing lots of mitochondria
Containing plasmids
Having flagella
Root hair cells have a large surface area in order to allow more molecules to be diffused and transported across.
Receptor cells detect stimuli
What is diffusion?
The movement of particles in a fluid from an area of high concentration to low concentration (with the concentration gradient) across a partially permeable membrane
The movement of particles in a fluid from an area of high concentration to low concentration (with the concentration gradient) across a fully permeable membrane
The movement of particles in a fluid from an area of low concentration to high concentration (against the concentration gradient) across a partially permeable membrane
The movement of particles in a fluid from an area of low concentration to high concentration (against the concentration gradient) across a fully permeable membrane
A tissue is a group of cells with similar function and structure
What are 3 examples of animal tissues?
Muscle tissue
Epidermal tissue
Glandular tissue
Mesophyll
Xylem
Phloem
What 4 tissues are examples of plant tissues?
Organs are made up of tissues
