Term
Name the plant structures that have helped plants obtain needed resources.
Definition
leaves (collect light), roots (absorb water & nutrients)
Term
What structures help plants stand upright?
Definition
cell walls made from cellulose, vascular tissue
Term
What structures help plants stay moist?
Definition
stomata, cuticle, roots
Term
What structures help plants reproduce?
Definition
spores, pollen, seeds
Term
Give the 4 major groups of plants in the order they evolved?
Definition
mosses (first), ferns, gymnosperms, angiosperms
Term
Which of the 4 plant groups are nonvascular?
Definition
mosses
Term
Which of the 4 plant groups are vascular
Definition
ferns, gymnosperms, angiosperms
Term
What does nonvascular mean?
Definition
there are no vessels or veins to carry water or nutrients
Term
What does vascular mean?
Definition
the plants has vessels or veins to carry water and nutrients
Term
Which groups of plants reproduce using spores?
Definition
moss ferns
Term
Why do mosses & ferns need to live in a moist environment?
Definition
the sperm needs water to swim through to fertilize the egg
Term
How do mosses obtain water & nutrients?
Definition
through diffusion
Term
How are ferns more advanced than mosses? How is this an advancement?
Definition
Ferns have a vascular system. They are able to transport water/nutrients greater distances.
Term
How are gymnosperms more advanced than ferns? How is this an advancement?
Definition
they have seeds instead of spores
they don't have to live in moist environments to reproduce
Term
Explain how gymnosperms reproduce.
Definition
A male cone releases pollen. Pollen is spread through the wind to a female cone. The egg in the female cone is fertilized and becomes a seed. When the seed is mature, it falls from the cone.
Term
Give examples of gymnosperms.
Definition
pine trees, fir trees, evergreens
Term
Give examples of angiosperms.
Definition
any flowering plant: daisy, grass, maple, apple tree, etc.
Term
How are angiosperms more advanced than gymnosperms? How is this an advancement?
Definition
angiosperms have seeds that are contained within an ovary
this provides extra protection
Term
Explain how an angiosperm reproduces.
Definition
The pollen from an anther lands on the stigma. The pollen travels down the style to the ovary, where it fertilizes the egg. The fertilized egg becomes a seed and the ovary becomes the fruit.
Term
Define chloroplast
Definition
found in the leaf cell, place where photosynthesis occurs
Term
define stomata
Definition
opening in leaf that allows gas exchange
Term
define guard cell
Definition
allows stomata to open and close
Term
define cuticle
Definition
waxy covering of leaf that reduces water loss
Term
define transpiration
Definition
evaporation of water
Term
define xylem
Definition
vessel in plants that carries water from root to leaves
Term
define phloem
Definition
vessel in plants that carries glucose from leaves to roots
Term
Why does water move through the xylem?
Definition
osmosis
Term
define sepal
Definition
protects flower during budding stage
Term
define stamen
Definition
male reproductive structure of plant
Term
define filament
Definition
holds up anther
Term
define anther
Definition
produces pollen
Term
define pollen
Definition
male gamete (sperm)
Term
define carpel/pistil
Definition
female reproductive structures of flower
Term
define stigma
Definition
catches pollen
Term
define style
Definition
connects stigma to ovary
Term
define ovary
Definition
where eggs are stored
Term
When an egg is fertilized in a plant it becomes a ____________.
Definition
seed
Term
Know the difference between self pollination and cross pollination.
Definition
Self: pollen fertilizes egg on same plant
Cross: pollen fertilizes egg on different plant
Term
What are some methods of pollination?
Definition
insects, butterflies, birds, bats, wind/water
Term
Know the difference between a fruit and vegetable.
Definition
Fruit: develops from an ovary
Vegetable: parts of the plant (stem, leaf, root, flower)
Term
Know how hormones can affect plant growth.
Definition
-stimulate growth/cell division
-inhibit growth during bad conditions
-stimulate fruit to ripen
Term
define phototropism
Definition
plant grows toward light
Term
define gravitropism
Definition
plant grows up, roots grow down
Term
define pesticide
Definition
kills pests (insects, weeds, diseases)
Term
define herbicide
Definition
kills weeds or unwanted plants
Term
define fertilizer
Definition
material used to provide plants with extra or missing nutrients
Term
Be able to label parts of the leaf & flower
Definition
see notes/diagrams
