Vascular and Non-Vascular

Question 3

What are plants?

Answer 3

eukaryotes that possess specialized organelles

Question 4

What are the three types of plant tissue?

Answer 4

Vascular, dermal and ground tissues

Question 5

Why do plant cells undergo mitosis?

Answer 5

So undifferentiated cells can become specialized

Question 6

What is an example of dermal tissue?

Answer 6

the epidermis and periderm

Question 7

Describe dermal tissue

Answer 7

2 tissue types. The outermost cell layers, that have thicker cell walls and is covered with a waxy cuticle.

Question 8

what is the role of dermal tissue?

Answer 8

protection against injury, herbivores, disease and water loss

Question 9

what is an example of vascular tissue?

Answer 9

xylem and phloem

Question 10

What are the characteristics of the xylem?

Answer 10

thick walled cells, dead at maturity

Question 11

What are the characteristics of the phloem?

Answer 11

thin walled cells, living at maturity

Question 12

what is the role of vascular tissue?

Answer 12

transportation of water and nutrients, support for the plant body

Question 13

describe the function of the xylem

Answer 13

mainly transporting water from the roots to the leaves and stem

Question 14

describe the function of the phloem

Answer 14

mainly transports food from the leaves to the roots and stem

Question 15

describe ground tissue

Answer 15

3 tissue types: parenchyma, collenchyma, sclerenchyma

Question 16

parenchyma

Answer 16

thin walled cells that are living at maturity

Question 17

what is the function of parenchyma?

Answer 17

perform cellular processes for growth and development, and store carbohydrates.

Question 18

collenchyma

Answer 18

thick walled cells tat are living at maturity

Question 19

what is the function of collenchyma?

Answer 19

perform cellular processes for growth and development, and support/protect plant body

Question 20

sclerenchyma

Answer 20

cells with lignin in their cell walls that are dead at maturity

Question 21

what is the function of sclerenchyma

Answer 21

support and protect the plant body

Question 22

what other type of tissue do vascular plants contain?

Answer 22

merestematic, aka the meristem

Question 23

what is the meristem and where is it found?

Answer 23

area of actively dividing undifferentiated cells, found in all areas of growth

Question 24

define cotyledon

Answer 24

structure in the seeds of flowering plants that stores nutrients
