Q

What is the function of a root?

A

To absorb water and as anchorage.

2
Q

What are the three types of roots?

A

Primary root, secondary root, root hairs.

3
Q

What is a primary root?

A

The first root that emerges from a seed.

4
Q

What are secondary roots?

A

Roots that emerge from a primary root and serve as anchors.

5
Q

What are root hairs?

A

Short strings that protrude from the longitudinal section of a root and absorb water.

6
Q

What are the parts of a longitudinal section?

A

The maturation region, elongation region, meristematic region, and root cap.

7
Q

What is the root cap?

A

Harder cells that grow downward and plow through rocks (like phineas and ferb’s terra drill 5000)

8
Q

What is the meristematic region?

A

Where mitosis occurs.

9
Q

What are the two types of meristems?

A

Apical meristems and cambiums.

10
Q

Do apical meristems grow lengthwise or widthwise?

A

Lengthwise at the top and the bottom of a root.

11
Q

Do cambiums grow lengthwise or widthwise?

A

Widthwise.

12
Q

Are cambiums always there?

A

No.

13
Q

What is elongation?

A

When cells grow lengthwise.

14
Q

What is maturation?

A

When cells get jobs and become specialized.

15
Q

What are the three types of root systems?

A

Tap root, fibrous, adventitious.

16
Q

What are tap roots?

A

Roots that have bigger primary roots than secondary roots.

17
Q

What is an example of a tap root?

A

Carrot.

18
Q

What are fibrous roots?

A

Roots that have same size primary roots as secondary roots.

19
Q

What are examples of fibrous roots?

A

Most trees.

20
Q

What are adventitious roots?

A

Roots that stem after plants have grown.

21
Q

What are examples of adventitious roots?

A

Vines, corn.

22
Q
