Connects to form a
Network
Branches of connections

Question 4

Muscle cells: MEC

Answer 4

Mitochondria provides Energy for Contractions

Question 5

Hair root cells: Branches with Minerals

Answer 5

Big Surface area for absorbing Minerals and water

Question 6

Phloem/Xylem: Food can’t fit through Xylem

Answer 6

Phloem- carries food Xylem-carries water
Xylem is hollow and has few subcellular structures for water to flow through

Question 7

Mitosis: Growing Limbs contain many divisions

Answer 7

Growth and Repair of cells and formation of second chromosome pair.
Line up- chromosomes line up
C-ell fibres pull them appart
M-embranes form around the chromosomes
D- ivision of cell membranes and 2 new daughter cells are formed that are identical to one another

Question 8

Stem Cells: Meristems beautifully clone rare species for disease resistance

Answer 8

(Meristems)
(Adult)Bone marrow-contains stem cells
C-hanges are made through differentiation so the cell becomes specialised
R-eplace faulty cells
D-estroying human life (embryonic)
Rejection of stem cells

Question 9

Theraputic cloning:

Answer 9

Embryo are made to have same information as the patient
