synthesis of high energy organic compounds from low energy inorganic compounds

Question 2

Unicells

Answer 2

Single cells (motile or non-motile)

Question 3

Colonies

Answer 3

assemblages of either variable number of cells or a constant number of cells

Question 4

Filaments

Answer 4

Daughter cells remain attached after division
Unbranched or branched
Uniseriate (single series of cells) or multiseriate (fusion of filaments)

Question 5

Coenocytic

Answer 5

Multinucleate cell with cross walls

Question 6

Parenchytomous form

Answer 6

Three-dimensional thallus

Question 7

Pseudoparenchytomous form

Answer 7

Superficially resemble parenchyma
Composed of aggregate filaments or amorphous aggregations of cells

Question 8

Zoospores

Answer 8

flagellated cells
produced in vegetative cells or specialized cells
Contains components needed to form new individual

Question 9

Aplanspore

Answer 9

Non-motile but have genetic capacity to develop flagella

Question 10

Autospore

Answer 10

Non-motile with no ability to develop flagella
miniature versions of parents

Question 11

Fragmentation

Answer 11

Controlled breaks in filaments of non-coenobic colonies
Each piece continues to grow

Question 12

Autocolony

Answer 12

produce miniature versions of coenobia

Question 13

Akinete

Answer 13

specialized resting cell (cyanobacteria)

Question 14

Isogamy

Answer 14

Two identical gametes fuse (+ and -)

Question 15

Anisogamy

Answer 15

Two different shape/size or behaviour gametes fuse

Question 16

Oogamy

Answer 16

small motile or non-motile gamete (male) fuses with larger immobile gamete (female)

Question 17

Monoecious

Answer 17

Same individual produces male and female gametes

Question 18

Dioecious

Answer 18

Male and female gametes produced by different individuals

Question 19

Homothallic

Answer 19

Gametes of genetically similar individuals fuse and produce viable offspring (self-fertile)

Question 20

Heterothallic

Answer 20

Gametes of genetically different individuals needed for viable offspring (self-sterile)

Question 21

Zygotic meiosis

Answer 21

meiosis takes place on zygote
only diploid cell is the zygote
vegetative state and gametes are haploid

Question 22

Gametic meiosis

Answer 22

Meiosis produces haploid gametes
The diploid zygote undergoes mitotic divisions to produce diploid vegetative state

Question 23

Sporic meiosis

Answer 23

Meiosis produces haploid spores
Haploid body: gametophyte
Haploid gametes produced by mitosis of gametophyte
Diploid zygote produces diploid sporophyte by mitosis

Question 24

Isomorphic

Answer 24

gametophyte identical to sporophyte

Question 25

Heteromorphic

Answer 25

gametophyte and sporophyte dissimilar

Diplobiontic

Answer 27

two stages of free living

Question 28

Haplontic

Answer 28

single predominant haploid phase

Question 29

Diplontic

Answer 29

single predominant diploid phase

Question 30

Haplodiplontic

Answer 30

two phases haploid and diploid
