Flowering plants that produce seeds inside a protective covering called a fruit wall or pericarp.

Angiosperm

1

Bear naked seeds which are exposed on cones.

Gymnosperm

2

Fruit wall.

Pericarp

3

Plants are composed of 3 vegetative organs:

Roots, stems, and leaves

4

Both angiosperms and gymnosperms use __________ __________ to transport water and nutrients between roots and shoots.

Vascular tissue

5

Transports water and dissolved minerals from the roots vertically to the shoots.

Xylem

6

Transports food made in leaves to the roots and parts of the shoot system.

Phloem

7

Two major categories of angiosperms are:

Monocots and Eudicots

8

The two smaller lineages that are closely related to the Eudicots:

Basal angiosperms and Magnoliids

9

All plant tissues are developed by embryonic cells called:

Meristems

10

Small clumps of cells located in the growing tips of stems and roots and are responsible for all elongation/vertical growth.

Apical meristems

11

Apical meristems occur in:

The tips of roots (RAM) and the buds of shoots (SAM)

12

The activity from RAM and SAM is know as:

Primary (1^O) growth

13

Cylinders of dividing cells that extend along the ke gtgs if roots and shoots except at the tips.

Lateral meristems

14

Lateral meristems are made up of two separate layers of tissues:

Inner vascular cambium and outer cork cambium

15

The activity from lateral meristems is called:

Secondary (2^O) growth

16

The two separate layers of tissues associated with lateral meristems are responsible for:

Plant girth growth or widening

17

Most of the tissue produced during second growth is __________, more commonly called what?

2^O, wood

18

Cork cells produce a waxy material, __________, which protects the plant from physical damage and pathogens, as well as protecting plants against excessive water loss.

Suberin

19

The layers of cork and cork cambium that help protect the plant make up the tissue known as:

Periderm

20

Raised opening on the periderm called __________ help in gas exchange.

Lenticels
