Specialised Cells Flashcards
Name all the specialised cells in a plant
Root hair
Palisade cell
Name all the specialised cells in an animal cell
Lymphocyte
Red blood cell
Sperm cell
Neutrophil
Egg cell
Name the 3 features of a palisade cell
> chloroplasts
vacuole
narrow air gaps between cells
Name the 3 features of a root hair cell
> mitochondria
large surface area
carrier proteins in the membrane
What is the benefit of a palisade cell having many chloroplasts
maximise photosynthesis
What is the benefit of a palisade cell having narrow air gaps between the cell
co2 can enter
o2 can leave
What is the benefit of a palisade cell having a large vacuole
Supports the cell
ensures chloroplast are at the edge of the cell
What is the benefit of a root hair cell having many mitochondria
provide ATP required for active transport
What is the benefit of a root hair cell having many carrier proteins in the membrane
ions can enter via active transport
What is the benefit of a root hair cell having a large SA
Takes up as much ions as possible
What are the 4 features Lymphocytes
Large nucleus
Produce antibodies
Memory cells
Destroy infected cell
What are the 3 features of the red blood cell
Lots of haemoglobin ( 02 and co2 bind)
No nucleus (more space for haemoglobin)
Biconcave shape ( large SA to volume ratio)
What are the 3 features of the sperm cell
Acrosome (enzymes to digest protective layers of egg)
Mitochondria -in collar (provide ATP energy for movement)
Small + Tail (swim to egg in fast movement)
What are the 3 features of the Neutrophil
Nucleus -lobed (flexible and can squeeze cells in capillary wall)
Lysosome (contain enzymes to digest pathogen)
Engulfs ( destroy pathogen by phagocytosis)
What are the 3 features of the Egg cell
Large cytoplasm (lots of organelles provide nutrients)
Zona pellucida (extra protection- more than 1 sperm entering)
Corona radiata (extra layer of cells and provide proteins for cell)
