Term
Angiosperm
Definition
flowering plant
Term
Anther
Definition
the top of the filament, where pollen is produced.
Term
Cambium
Definition
cells that divide to produce new phloem and xylem
Term
Cone
Definition
Reproductive structure of Gymnosperms
Term
Dicot
Definition
This type of angiosperm has 2 cotyledons, has wide leaves, petals in groups of 4 or 5. Examples are beans, roses, oak trees
Term
Filament
Definition
the thin stalk part of the stamen
Term
Flower
Definition
the reproductive structure of an angiosperm
Term
Germination
Definition
occurs when the embryo begins to grow and pushes out of the seed.
Term
Gymnosperm
Definition
a seed plant that produces seeds that are not enclosed by a protective fruit.
Term
List the 3 parts of a seed
Definition
Seed Coat, Young Plant (zygote), Cotyledon
Term
List the 4 ways seeds are dispersed
Definition
- other organisms
- wind
- water
- ejection
Term
List the two characteristics of seed plants
Definition
- vascular tissue
- reproduce by using pollen and seeds
Term
List the two main types of root systems
Definition
- fibrous
- tap root
Term
Monocot
Definition
This type of angiosperm only has 1 cotyledon, has petals in 3's, and long slender leaves. Examples are grasses and tulips
Term
Name 2 functions of all roots
Definition
Anchor Plant in the ground, absorb water and minerals
Term
Name the 2 types of Angiosperms
Definition
Monocots, Dicots
Term
Name the four groups of Gymnosperms
Definition
Cycads, Conifers, Ginkoes, Gnetophytes
Term
Name the two kinds of stems
Definition
- herbaceous (soft)
- woody
Term
Ovary
Definition
contain one or more ovules, protects the seeds as they develop
Term
Ovule
Definition
a structure that contains an egg cell
Term
Petal
Definition
colorful, leaf-like structure of some flowers
Term
Phloem
Definition
vascular tissue through which food flows
Term
Pistil
Definition
the female part of the flower, usually found in the center, includes the stigma, style and ovary.
Term
Pollen
Definition
tiny structures that contain the cells that will later become sperm cells
Term
Root Cap
Definition
structure that covers the tip of a root, protecting the root from injury
Term
Seed
Definition
a structure that contains a young plant inside a protective covering
Term
Sepal
Definition
green, leaf-like structures that enclose and protect the flower while it is still a bud
Term
Stamen
Definition
the male reproductive parts of the flower, includes the filament and anther
Term
Stigma
Definition
the sticky tip of the pistil
Term
Style
Definition
the hollow tube the connects the stigma to the ovary at the base of the flower.
Term
Transpiration
Definition
the process by which water evaporates from a plant’s leaves
Term
Why does a seed that is dispersed far from its parent have a better chance of survival?
Definition
b. When a seed does not have to compete with its parent for light, water, and nutrients, it has a better chance of becoming a seedling.
Term
Xylem
Definition
vascular tissue through which water and minerals move
