Topic 11- The evolution of plants

Question 1

Plants/ the plant group are also called…

Answer 1

embryophytes

Question 2

Multicellular diploid is also called…

Answer 2

sporophyte

Question 3

Multicellular haploid individual is also called…

Answer 3

gametophyte

Question 4

What does the cuticle of a plant do?

Answer 4

protects against desiccation

Question 5

What does the stomata of a plant do?

Answer 5

pores in the epidermis of the leaves and stems that allow gas exchange and water loss regulation

Question 6

What are non-vasucular plants that do not produce seeds or flowers called?

Answer 6

Bryophyte (moss)

Question 7

Group of vascular plants whose life cycle is dominated by the sporopyte (choose one):

byophyte
lycophytes
tracheophytes
monilophytes

Answer 7

tracheophytes

Question 8

Do not produce seeds or flowers rather they produce spores that form a group called pteridophytes (choose two):

byophyte
lycophytes
tracheophytes
monilophytes

Answer 8

lycophytes and monilophytes

Question 9

What is vascularization?

Answer 9

Presence of lignified tissues that transport water, nutrients and sugars through the plant

Question 10

Define the two specialized transport tissues
Xylem and Phloem of vascularization

Answer 10

Xylem: water and minerals to the leaves
Phloem: sugars, the products of photosynthesis

Question 11

Production of spores- Leaves can be specialisez (sporophylls) to produce spores… Homosporous and hetereosporous, diffrenciate the two

Answer 11

Homosporous: only one type of spore producing a bisexual gametophyte
—-> most seedless vascular plants

Heterosporous: two types of spores producing either female gametophyte or a male gamotophyte
—> All seed plants

Question 11

Production of spores- Leaves can be specialisez (sporophylls) to produce spores… Homosporous and hetereosporous, diffrenciate the two

Answer 11

Homosporous: only one type of spore producing a bisexual gametophyte
—-> most seedless vascular plants

Heterosporous: two types of spores producing either female gametophyte or a male gamotophyte
—> All seed plants

Question 12

Ferns are monilophytes and also considered HO…
finish the word

Answer 12

homosporous

Question 13

what produces seeds but no flowers?
(choose 1)

seeds
gymnosperms
spermatophytes
angiosperms
ovule

Answer 13

Gymnosperms (‘naked seed’)

Question 14

what produces seeds and represent 90% of all living plant species ?
(choose 1)

seeds
gymnosperms
spermatophytes
angiosperms
ovule

Answer 14

angiosperms

Question 15

What are the five key innovations of seed plants:

Answer 15

1. An extrememly reduced gametophyte is protected from environnmental stresses
2. Ovule: structure containing the megaspore
3. Seed plants are heterosporous
4. pollen grain
5. production of a seed

Question 16

The BLANK matures into a fruit

The BLANK matures into seeds

Answer 16

The OVARY matures into a fruit

The OVULES mature into seeds
