Waxy, clear layer that keeps plants from drying out
What is a cuticle
100
Food is made in this plant structure
What is a leaf
100
A rootlike structure that holds nonvascular plants in place
What is a rhizoid
100
Green pigment that captures energy from the sun
What is chlorophyll
100
Transfer of male cones to female cones
What is pollination
200
Process in which plants use carbon dioxide, water, and energy from the sun to make food
What is photosynthesis
200
Type of root that has one main root and grows downward
What is a taproot
200
Definition of nonvascular
What is a plant with no vascular tissue to move water and nutrients through the plant
200
Sperm is found inside this structure
What is pollen
200
Type of plant that produces fruits and flowers
What is an angiosperm
300
These are 2 organelles unique to plant cells (not present in animal cells)
What are chloroplasts and a cell wall
300
May be herbaceous or woody
What is a stem
300
Name 2 examples of nonvascular seedless plants
What are mosses, liverworts, or hornworts
300
Seed leaves of the young plant
What are cotyledons
300
Three types of gymnosperms
What are conifers, gingkoes, cycads (palms) or gnetophytes
400
Scientists believe plants may have originated from this
What is green algae
400
Vascular tissue that transports minerals, water, and food through the plant
What are xylem and phloem
400
Examples of seedless vascular plants
What are club mosses, horsetails, and ferns
400
Two leaf adaptations
What is modifying as spines (cactuses) or leaves modified to catch insects (sundew)
400
Two advantages seed plants have over seedless plants
What is when a seed begins to grow, the young plant uses the food stored in the seed, and seeds can be spread by animals (more efficiently)
500
These are the 2 reproductive stages plants go through in their life cycle
What are sporophyte and gametophyte
500
Three jobs of roots
What are to hold a plant in the soil, to supply plants with water and dissolved minerals, and to store surplus food made during photosynthesis
500
Three reasons nonvascular plants are important
What is they are the first plants to live in new environments, when they die they form a thin soil layer for other plants to grow in, hold soil in place and reduce erosion, animals eat and nest in them, peat moss-can be dried and burned for fuel and used in potting soil
500
Seed plants with one cotyledon
What is a monocot
500
Three reasons angiosperms are important
What is provides animals food, major food crops, building materials, to make clothing/rope, medicines, rubber, perfume oils
