Question 19

function, adaptation and looks of root hair cells

Answer 19

functions - absorption of water and dissolved mineral ions form soil
adaptation - finger like extension to provide large SA to V ratio (more absorption of water)
looks - like a finger or a hair brush

Question 20

function, adaptation and looks of xylem cells

Answer 20

function - supports and conducts water through plants
adaptation - walls are strong and do not collapse, no cell contents so the tubes are hollow and water can flow through
looks - narrow, hollow, elongated tube

Question 21

function, adaptation and looks of palisade mesophyll cells

Answer 21

function - photosynthesis in leaves
adaptation - contains many chloroplasts, has tall shape to absorb light passing through
looks - a tall rectangular box

Question 22

function, adaptation and looks of guard cells

Answer 22

function - gas exchange in cells in response to changing environmental conditions, takes CO2, releases O and absorbs water to diffuse oxygen out
adaptation - allow gas exchange, control water within the leaf, fill it with water, and release it to open stomata
looks - stoma open, 2 brackets, stoma closed, birds eye view of brain

Question 23

function, adaptation and looks of nerve cells

Answer 23

function - conduction of electrical impulses
adaptation - long fiber carrying messages up and down the body, over extended length
looks- tiny hair structures growing from ends like small trees

Question 24

function, adaptation and looks of egg cells

Answer 24

function - reproduction, fuse with male gamete, fertilized
adaptation - cytoplasm has large volume of nutrients to help embryo grow
looks - circle with crown surrounding it (huge)

Question 25

function, adaptation and looks of sperm cells

Answer 25

function - reproduction, fuse with female gamete, fertilized
adaptation - has long flagellum to allow sperm to travel to egg, needs lots of energy, lots of mitochondria
looks - looks like a balloon

Question 26

function, adaptation and looks of red blood cells

Answer 26

function - transport oxygen through blood stream
adaptation - hemoglobin, a protein which transports oxygen, has no nucleus, move volume inside for protein, biconcave shape gives large SA
looks - red moon

Question 27

function, adaptation and looks of ciliated cells

Answer 27

function - movement of mucus in the trachea and bronchi, and ovum and zygote
adaptation - have cilia that constantly move and sweep mucus
looks - box with hair extensions
