Cell Function And Organelles Flashcards
What happens to multicellular eukaryotic organisms ?
Become specialised to carry out specific functions
Why is the shape of cell so significant ?
Helps to carry out its function
What will a cell have the uses a lot of energy ?
Mitochondria
Produce atp / release energy
What will a cell need if it makes a lot of proteins?
Ribosomes
What/ where are epithelial cells ?
Small intestine - absorb food efficiently.
What features do the small intestine have to help them absorb food efficiently v
Finger like projections - villi. Increase surface area for absorption.
Microvilli , increase surface area even more.
Mitochondria to provide energy for transport of digested food molecules into cell
What are red blood cells / why are they adapted for function ?
Adapted to carry oxygen around the body in bloodstream.
No nucleus to make room for oxygen carrying compound haemoglobin.
What are sperm cells why are they adapted for function c
Cell in fertilisation
Contain lots of mitochondria in heads to provide large amounts of energy to propel themselves towards egg
Specialised cells grouped together to form …
Tissues
What is a tissue
Group of cells working together to perform a particular function
Different tissues work together to form…
Organs
Different organs make up …
Organ system
Example of cell organisation
Epithelial cells make up epithelial tissue.
Epithelial / muscular and glandular tissue all work together to form stomach - an organ.
Stomach part of digestive system - organ system made up of all the organs involved in digestion and absorption of food.
