She comes back in 2025, 25years later The tree grows 2 feet a year. Where would the nail be? A) 50 feet B) 56 feet C) 26 feet D) 6 feet E) 4 feet

Solution

ANSWERS :

a)Collenchyma : parenchyma cells inside vascular ring in edudicot stem

b)endodermis : cell layer in root regulating movement in vascular cylinder

c) Pith : Supporting cells with thick secondary wall

d) Sclerenchyma : Supporting cells with thick primary wall

e) Vascular cambium : produces secondary xylem and phloem

ANGIOSPERM :

PLANT STRUCTURE :

a) Apical meristem : Result in primary growth

b) axillary buds : Found between the petiole and stem

c) Tuber : Modified stem

d) Vessel elements : Cells that conducts water through plants

e) Wood : Accumulation of secondary xylem

PLANT GROWTH :

a) annual : Plants that complete their life cycle in a year or less

b) Biennial : Plants with a life cycle of two years

c) Perennial : Plantss which live for many years

d) Root cap: Protects apical meristem of root tip

Monocot	eudicot
Fibrous root	Tap root
Scattered vascular bundles in the stem	Vascular tissue in a ring in stem
Leaves with parallel veins	Leaves with branching venation
no secondary growth	Produces cork cambium
