Cells Booklet 2 - First Form Flashcards
If an organism only has one cell what is it called
A Uni-cellular organism
If an cell organism has a cell membrane, cytoplasm, chloroplast & a nucleus; is it an animal or plant cell and why.
It’s an animal cell because it doesn’t have a cell wall or a vacuole.
What was the above cell called
A Euglena
What was the euglena’s extra part that hasn’t been mentioned.
The Whip Like Flagellum
What is a flagellum used for
For Movement
How do substances move in and out of cells?
Diffusion
What substances move into cells?
Oxygen & Glucose needed by the cell.
What substances move out of cells?
Waste Products such as Carbon Dioxide.
Name 3 examples of diffusion in real life
-> Teabags in hot water
-> Potassium Permanganate in water
-> Air Freshener
What is the definition of diffusion?
The movement of particles from a high concentration to a low concentration until equilibrium(everything equal)
Finish this sentence: The bigger the difference in concentration…
the faster the rate of diffusion will be.
If you have a petri dish of agar(universal indicator) and make two holes and put acid in one and alkali in the other. What does it look like and why.
It turns red on the side where the acid was put in, green on the side where the alkali was put in & a yellow stripe down the middle where the meet and have neutralised each other.
What is the function of a palisade plant cell?
To carry out photosynthesis using energy from sunlight.
What is the function of a nerve cell
To transmit electrical impulses around the body to co-ordinate responses
What is the function of a ciliated epithelial cell
To move microorganisms and dust away from the lungs
What is the function of an egg cell
To be fertilised by the sperm cell
What is the function of a root hair cell
To absorb water and minerals from soil
What is the function of a sperm cell
To fertilise an egg cell and make a baby
What is the function of a red blood cell
To carry oxygen around the body
Name the adaptations of a root hair cell
-> Large Surface Area
-> No Chloroplasts
What are the adaptations of a sperm cell
-> Long tail to swim
-> Lots of mitochondria to provide energy
-> Chemicals in the head to get into the egg cell
What are the adaptations of a red blood cell
-> Biconcave shape to easily move through blood vessels
-> Large surface area for diffusion
-> No nucleus
-> Contains haemoglobin
What are the adaptations of a palisade cell
-> Tall and thin
-> Lots of chloroplasts for photosynthesis
What are the adaptations of a nerve cell
-> Long thin axon
-> Branching dendrites at either end
-> Can carry electrical impulses.
What are adaptations of a ciliated epithelial cell
-> Tiny hairs called cilia to sweep particles away
-> Lots of mitochondria to provide energy
What are the adaptations of an egg cell
-> Cytoplasm contains nutrients for developing the embryo
-> Membrane changes after fertilisation to stop any more sperm getting in
