Bryophyte & Lycophytes - Alternation of Generations
Where is their location of growth at?
Apical meristems
Name the four challenges of terrestrial life
-maintaining water
-obtaining resources
-support
-reproduction & dispersal of offsprings
"Form Follows Function" is said by who?
Louis Henri Sullivan
What am I?
-Contains one cotyledon
-Veins in leaves are parallel
- Flower petals are in multiples of 3's
Monocot
What kind of plants are the angiosperms known as?
"The flowering plants"
What are the female and male structures called?
-Archegonia
-Antheridia
Haploid or Diploid
1. Sporangium
2. Sporophyte
3. Gametophyte
1. Diploid (2n)
2. Diploid (2n)
3. Haploid (1n)
-adventitious roots
-tuberous roots
-tap roots
-fibrous roots
What am I?
-contains two cotyledons
-leaf netlike
-Flower petals are in multiples of 4's and 5's
Eudicots
Compared to Gymnosperms, how are angiosperms different?
Their seeds are covered and protected with an outside layer
Describe bryophytes and give at least 3 examples of them
-Non vascular seedless plants
-Liverworts, hornworts, mosses
What are some ways seeds can produce the next generation of plants?
-By wind
-By humans or animals
-By water
What are the roots functions?
-absorption
-anchoring
-storage
-vegetative reproduction and competition
When looking at a monocot stem, how do the vascular bundles look like?
Usually scattered
What many phylums does the angiosperms have and what is it called?
Since Bryophytes and Lycophytes lack any vascular tissues to help with moving water and minerals, what do they do instead?
Diffusion and osmosis
Name the Genus and which phylum they are in.
-Female plant have large strobili or cones
-Can also be pollinated by beetles
Genus Gymnosperms
Phylum Cycadophyta
Give an example of a simple fleshy fruit. Which part of the fruit is not fleshy?
-tomato, asparagus, grapes, avocado
-the exocarp (skin) is not fleshy
When looking at a eudicot stem, how do the vascular bundles look like?
Its shaped in a ring
The Angiosperms are split into two groups, what are they and how do they differ?
-Monocots (forms only one seed leaf)
-Eudicots (forms two seeded leaves)
Describe the bryophyte moss life cycle
-begins their life as a haploid spore
-becomes a mature gametophyte with roots like rhizoids that help with anchoring the plant
-develops haploid reproductive structures at top of the gametophyte
What are the differences between Gymnosperms & Angiosperms when compared to Bryophytes, Lycophytes, and Pterophytes?
-Gymosperms and Angiosperms have adaptations to dry land while Bryophytes and others cannot reproduce without water
-Gymosperms and Angiosperms have a protected coat to their seeds while Bryophytes and others do not
What are the two dry fruit classifications? Differentiate them and give examples.
1. Dry dehiscent (fruits that split open at maturity)
-legume: peas, peanuts
2. Dry Indehiscent (fruit remains intact even after maturity)
-achene: dandelion, sunflower
Compared to the stem of monocots, how do eudicots stem look like? Where are their xylem?
In a ring shape, usually in the center of the eudicots' roots
Explain why angiosperms are able to survive more than gymnosperms?
Angiosperms can adapt to their habitat to which where their seeds produces more and matures much quicker.
