Science Flashcards
where do you find a cell membrane?
In plant and animal cells
what is a cell membranes function?
To control what substances go out of and into the cell.
where do you find cytoplasm?
in plant and animal cells
What is cytoplasm’s function?
Jelly-like substance where chemical reactions take place.
Where do you find a nucleus?
In plant and animal cells
What is a nucleus’s function?
It carries all the genetic information and controls what happens inside the cell.
Where do you find a chloroplast?
Only in plant cells that are above the ground
What is a chloroplast’s function
Where the photosynthesis takes place na contains a green substance called chlorophyll.
Where do you find the vacuole?
In plant cells only
What is a vacuoles function?
Contains liquid called sap which keeps the cell firm
Where do you find a cell wall?
In plant cells only
What is the function of the cell wall?
The function of the cell wall is to support the cell it is made up of a strong substance called cellulose.
Where do you find mitochondria?
In animal cells and plant cells
What is a mitochondria’s function?
It provides energy for the cell by the process of respiration
What is a Red blood cell’s function?
To carry oxygen
What is a red blood cell’s special features?
No nucleus for a large surface area to absorb more oxygen.
What is a nerve cell’s function?
To carry nerve impulses to different parts of the body.
What is a nerve cell’s special features?
It is long for transporting messages quickly around the body.
What is a sperm cell’s function?
to fertilise the egg.
What is a sperm cell’s special features?
Tail for swimming to the egg and lots of mitochondria for energy.
What is a root hair cell’s function?
To absorb water and minerals.
What is a root hair cell’s special feature?
Large surface area
What is a leaf cell’s function?
To absorb sunlight for photosynthesis.
What is a leaf cell’s special features?
Lots of chloroplasts and large surface area
How are specialised organs made up?
Specialised cells make up specialised tissues which make up specialised organs.
How are the lungs adapted to their function?
They have a large surface area for absorbing more oxygens
How are the small intestines adapted to their function?
They have a large surface area for absorbing food from the body.
What do the arrows in food chains represent?
They represent the flow of energy
What is K?
Potassium and a Metal
