Cell Division Key Words 3

Question 1

Erythrocytes

Answer 1

Red blood cells w/ nice cave shape, flexibility and few organelles to increase space available for haemoglobin

Question 2

Neutrophils

Answer 2

White blood cell type w/ multi-lobed nucleus to squeeze through small gaps and granular cytoplasm containing lysosomes

Question 3

Sperm cells

Answer 3

Male gametes for fertilising female gamete. Flagellum for movement, many mitochondria to supply energy and acrosome containing digestive enzymes

Question 4

Epithelial tissue

Answer 4

Tissue of cells adapted to cover internal and external body surfaces. Squamous and ciliated epithelium are examples.

Question 5

Ciliated epithelium

Answer 5

Cells w hair-like structure cilia. Work with goblet cells which produce mucus. In trachea, mucus traps particles and pathogen and cilia waft away

Question 6

Xylem

Answer 6

Vascular tissue transports water and minerals through plant. Composed of vessel elements, elongated dead cells strengthened with lignin.

Question 7

Phloem

Answer 7

Vascular tissue transports organic nutrients (sucrose) from photosynthesis site to where needed. Comprised of sieve tube elements separated by sieve plates. Associated w companion cells.

Question 8

Potency

Answer 8

Stem cell’s ability to differentiate into different cells. (Greater # cells, greater potency)

Question 9

Totipotent

Answer 9

Stem cells can differentiate into any cell type, including extra-embryonic tissues (placenta)

Question 10

Pluripotent

Answer 10

Stem cells form all tissue types except extra-embryonic tissues

Question 11

Multipotent

Answer 11

Stem cells form cells within particular tissue type
