Tassals

3

What are the female reproductive organs known as?

Husk, silk, the ova and supporting husk

What is a plant that grows, reproduces, then dies all in one year?

Annual-corn is an example

6

What is a plant that lives for many years called?

A Perennial

7

What are the 3 types of plant tissue (General) and what are they for?

Epidermal-protection
Ground-Storage and support
Vascular-Transport

11

What does Parenchyma do?

Juice and Starch support

12

What does Collenchyma do?

for flexible support

13

What does sclerenchyma?

for firm support

Where is primary plant growth taking place?

Lengthwise, occuring at tips of roots and stems

17

Where is secondary plant growth taking place?

Diameter wide growth

18

What is responsible for primary growth?

Apical and Root meristems

What are the three parts to external leaf structure?

blade, Veins, and Petiole

21

What is the petiole?

Attaches the blade to the stem

22

What does the epidermis of the leaf contain on the underside for gas exchange?

Stomas

23

What are palisade cells and where are they located?

Palisade cells are tightly packed cells on the top of the leaf

24

What are spongy cells and where are they located?

Looser packed cells on the bottom of the leaf

25

What is a pith?

Starch storing ground tissue in Monocots and Annual Eudicots

What are the photosynthesising cells under bark?

Cortex

30

What produces new xylem and phloem each year?

Vascular Cambium
