Specialised cells Flashcards
Function of a root hair cell
Absorbs water and minerals
Adaptations of a root hair cells
They have long microscopic hairs that can fit between grains of soil to absorb water and minerals. They also have a large surface area for the absorption of water and minerals.
Function of palisade cells
They carry out photosynthesis and make food for the plant.
Adaptations of palisade cells
They have lots of chloroplasts that absorb light for photosynthesis. They also have a tall, long shape which gives them a large surface area for the absorption of light.
The function of a sperm cell
Fuses with an egg cell for fertilisation.
Adaptations of a sperm cell
Has a long tail called a flagella to swim to the egg cell. Has lots of mitochondria that produce energy for the sperm’s movement.
Adaptations of a sperm cell
Has a long tail called a flagella to swim to the egg cell. Has lots of mitochondria that produce energy for the sperm’s movement.
The function of a ciliated epithelial cell
They prevent mucus, bacteria and dust from getting into the lungs.
The adaptations of a ciliated epithelial cell
They have tiny hairs that waft mucus through the airway. They also have lots of mitochondria that give energy to the tiny hairs for their movement.
The function of an white blood cell
They prevent disease.
The adaptations of a white blood cell
They can change shape to squeeze out blood vessels and engulf pathogens.
The function of a muscle cell
They help the body to move
Adaptations of a muscle cell
They have bands of protein that can change shape to contract and relax the muscles. They have lots of mitochondria that produce energy for the muscles to contract.
The function of a red blood cell
They carry oxygen around the body.
The adaptations of a red blood cell
They have a biconcave shape to have a large surface area for the absorption of oxygen.
The function of an egg cell
They are fertilised by sperm cells.
Adaptations of an egg cell
Their cell membrane changes after fertilisation so that no more sperm can get in.
