Specific Cells Flashcards
What are the adaptations in a sperm cell?
In a sperm cell the Nucleus only contains 50% DNA as it doesn’t need more than 50% because it will merge with the egg cell. The flagella allows the cell to swim towards the egg cell and there is a chemical on the front that helps it enter the egg cell.
What are the adaptations in a red blood cell?
The red blood cell doesn’t have a nucleus as it needs more space for Haemoglobin.
What are the adaptations in a palisade cell?
The palisade cell has lots of chloroplast to help it carry out photosynthesis. Its rectangular shape increases the surface area for photosynthesis. Palisade cells are located on the top of the leaf to absorb light energy.
What are the adaptations in an egg cell?
The nucleus only contains 50% of the DNA a normal body cell has. The outer jelly coat only allows one sperm cell to fertilise.
What are the adaptations in a ciliated epithelial cell?
Cilia wafts an egg cell in the oviduct towards the uterus. It also wafts mucus in the trachen (wind pipe) towards the mouth so it can be expelled.
What are the adaptations in a skeletal muscle cell?
There is lots of mitochondria to provide energy for muscular contraction.
What are the adaptations in a fat cell?
Fat cells can expand up to 1000x as it fills with fat. It has very little mitochondria as it does not need a lot of energy. There is also a very small amount of cytoplasm so that the cell can have large fat store.
What are the adaptations in a neurone (nerve cell)?
The axon is insulated by a fatty sheath so electrical impulses can move along the axon. Long axon transmits electrical impulses over long distances.
What are the adaptations in a white blood cell?
It is an irregular shape so they can squeeze out of blood vessels to the site of infection. It produces antibodies to destroy pathogens. (Pathogens are: bacteria, viruses and fungi.)
What are the adaptations in a root hair cell?
No chloroplast as the roots cannot access light energy. Lots of mitochondria to provide energy for ions to move across the cell membrane.
