characteristics of all plants:
|
eukaryotic, autotrophic, multicellular
|
|
all plants go through an alteration of _______
|
generations
|
|
the _________stage produces spores
|
sportophyte
|
|
the gametophyte generation produces _______
|
gametes (sex cells)
|
|
the ferilization of an egg by a sperm creates _____,which grows into an ______.
|
zygote; embryo
|
|
seedless, nonvascular plants:
(6 things) |
1. lack vascular tissue
2. reproduce using spores 3. low-growing b/c there is no way for water and materials to reach distant cells 4. the rootlike structures of mosses are rhyzoids 5. the leafy green moss plant is the gametophyte generation 6. the stalk and capsule of the moss plant is the sporophyte |
|
seedless, vascular plants
(7 things) |
1. have tissue vascular
2. reporoduce using spores 3. can grow taller because of vascular tissue 4. the underground stem of a fern is called a rhyzome 5. the leaf of a fern is called a frond 6. the stems and roots of ferns are underground 7. the leafy green fren is the sporophyte generation b/c it has sori(spore cases) on the underside of the leaves |
|
seed plants
(3 things) |
1. all have vascular tissue
2. seed plants reproduce using pollen (becomes the sperm cell)and eggs 3. parts of a seed: embryo, stored food, seed coat |
|
what is necessary for germination to occur?
|
water
|
|
what are 2 types of roots and an example of each?
|
fibrous (grass) and taproot (carrot)
|
|
what are the layers of the woody stem?
|
outermost: bark; sapwood is active xylem that transports water and material; heartwood is in active but provides support
|
|
_______is located between xylem and phloem and produces new ________ _________.
|
cambium; vascular tissue
|
|
annual rings are made from _________.
|
xylem
|
|
_____ make food for the plant
|
leaves
|
|
the most chloroplasts are located near the upper surface of the ________.
|
leaf
|
|
cuticle
|
a waxy water proof layer outside of a leaf, fruit, or vegitable
|
|
vascular tissue
|
a system of tublike structures inside a plant through which water, materials, and food move
|
|
zygote
|
a fertilizied egg
|
|
non-vascular tissue
|
plants that lack a well-developed system of tubes for transporting water and other materials
|
|
vascular plant
|
plants with true vascular tissue
|
|
rhiziod
|
thin, root like structure
|
|
frond
|
the leaf of a fern plant
|
|
pollen
|
tiny structures that contain the cells that will later become sperm cells
|
|
seed
|
a structures that contain a young plant inside a protective covering
|
|
embryo
|
a young plant that developes from the zygote or fertilized egg
|
|
cotyledons
|
a seed leaf
|
|
germination
|
when the embryo begins to grow again and pushes out of the seed
|
|
root cap
|
a structure that covers the tip of a root, projecting the root from injury
|
|
cambium
|
a layer of cells in a plant produces new phloem and xylem cells
|
|
transpiration
|
the process by which water evaporates from a plant's leaves
|
|
examples of seedless, non-vascular plants
|
mosses, liverworts, hornworts
|
|
examples of seedless vascular plants
|
ferns, horsetails, club mosses
