Specialised Cells [B] Flashcards
How are tissues, organs and organ systems formed?
Tissues are formed by a group of similar cells working together to perform a function.
Groups of tissues form organs.
Groups of organs form organ systems.
Organ systems form organisms.
How are Red Blood Cells specialised?
Bi-concave disc shape increases surface area.
Haemoglobin is found inside that carries oxygen.
Flexible to squeeze through narrow capillaries.
How are Palisade Cell specialised?
It is designed for photosynthesis.
Found in the top part of the leaf for more sunlight.
Packed with chloroplasts to make plant food. (Chloroplasts can move)
How are Sperm Cells specialised?
Designed to fertilise eggs.
Small and contains tail to swim.
Has special enzymes to digest into the egg.
They have mitochondria for energy.
How are Root Hair Cells specialised?
Elongated for more surface area.
Sap Vacuole lowers water potential so osmosis can happen.
Large Vacuole stores lot of water.
How are Egg Cells specialised?
Has a protective outer layer.
Store food in cytoplasm for embryo development.
Hardens after a sperm cell enters to prevent multiple penetrations.
How are White Blood Cells specialised?
Multi lobed Nuclei allows them to go through small gaps.
Lysosomes in the cytoplasm allows to digest pathogens.
