Types of Cells Flashcards
to know the adaptations of cells and the types of cells (12 cards)
What are unicellular cell
An organism which consists of 1 cell which is able to carry out all the processes for it to stay alive
What is a multicellular cell
An organism like an animal made up of alot of cells that divide
What is mitosis
Growth by cell division
What is the division of labour
Different cells carrying out different functions
Function and Adaptation of a Palisade leaf cell
Tall narrow cell packed with chloroplasts
To trap as much light as possible for photosynthesis
Function and Adaptation of a Root hair cell
Has a long extension called a roothair which increases surface area for the absorbtion of substances
Absorbs water and mineral ions from the soild
Function and Adaptation of a Sperm cell
Very small and has a tail called a flagellum for swimming and has many mitochondria to release the energy required for the journey
Fertilises an egg cell
Function and Adaptation of a Red blood cell
Dosent have a nucleus to leave more space for haemoglobin
Biconcave shape to increase surface area for oxygen absorbtion
Transporting Oxygen around the body
Egg Cell
Has a large cytoplasm which contains the nutrients and mitochondria needed for cell division after fertilisation
Has a special cell membrane which only allows one sperm to fertilise it
Fuses to a sperm cell during fertilisation to form a zygote
Nerve Cell
Thin long and wire like covered by a fatty sheath which gives electrical insulation and has many branch endings to connect with many other cells
To Carry electrical messages around the body
Muscle Cells
Can Contract and Relax
To bring about movement in animals
White Blood Cells
Big Nucleus To Build antibodies which are protein molecules that aid in the defence system against disease
Eliminate any Microorganisms which invade the body and can cause infection
