Chapter 16.4 Reproductive Strategies

Front 1

Steps in binary fission in a bacterial cell (4)

Back 1

1. attatchment of the circular bacterial chromosome to the cell wall

2. chromosome replicates, new chromosome attaches to cell wall as well

3. elongation of the cell

4. formation of a septum separates two chromosomes

Front 2

define vegetative reproduction

Back 2

a form of asexual reproduction in which a new plant grows from a modified stem

Front 3

define fragmentation

Back 3

asexual reproduction, new organism is created from a fragment

Front 4

diplooid generation of a plant

Back 4

sporophyte (spore making body)

Front 5

through the process of _______ a sporophyte produces one or more _______ ________

Back 5

meiosis, haploid spores

Front 6

in alternation of generations after the spores have been made do they develop with fertilization?

Back 6

no without fertilization

Front 7

each _____ spore grows into a _____ _____ called the _______

Back 7

haploid, plant body, gametophyte

Front 8

in conifers, such as a pine tree, the tree itself is the

Back 8

diploid sporophyte

Front 9

3 advantages if sexual reproduction:

Back 9

- variation/adaptation to a changing environment

- competition reduced if they are genetically diverse

- pairing homologous chromosomes and crossing over offers opportunities to replace or repair damaged chromosomes

Front 10

2 advantages of asexual reproduction:

Back 10

- quicker

- less energy required
