This review delves into the fascinating world of ferns and plant biology, exploring the underground growth of roots and stems, the differentiation of vascular and nonvascular plants, and essential processes like photosynthesis and plant hormone functions. Key characteristics of plants, their life cycles (sporophyte and gametophyte), and the roles of vascular tissues are covered. We also investigate the various reproductive structures, the significance of seed types, and the ecological adaptations of plants, especially in different environments.
E N D
What parts of a fern grow underground? • Roots and stem
T/F: Vascular and nonvascular plants differ in the way they transport materials. • True
What is auxin? • A plant hormone that speeds up the growth of plant cells
What food making process occurs in the leaves? • Photosynthesis
What are the characteristics of plants?(Hint, there are 4) • Eukaryotes • Multicellular • Autotrophs (even though some can also be heterotrophs, ALL are still autotrophs) • Have cell walls
What are structures B and C? Are they male or female? • B=filament • C=anther • Male
Where on a fern are spores located? • Underside of the leaf (frond)
What do spores that plants produce develop into? • Gametophytes
What produces the egg and sperm cells during a plant’s life cycle? • Gametophytes
What are the functions of vascular tissue? (Hint: there are 3) • Transport materials • Provide structure to the plant • Hold up the leaves to expose them to sunlight
What are the 2 stages of a plant’s life cycle? • Sporophyte and gametophyte
What do xylem and phloem transport? • Xylem=water and minerals; goes up • Phloem=food/sugar; goes down
What is structure A? What is its function? • Cuticle • Helps prevent water loss during transpiration
Name the 3 parts of a seed. • Embryo=young plant • Stored food • Seed coat
T/F: Phloem forms annual tree rings. • False; xylem
What characteristic do all gymnosperms share? • All produce naked seeds
What are cones? • Reproductive structures on gymnosperms
Which group (monocot or dicot) has scattered bunches of vascular tissue? • Monocot
What determines when a plant will flower? • The amount of darkness it receives
Name an example of a vascular plant. • There are many; anything except for mosses, liverworts, and hornworts
What are structures E, F, and G? Are they male or female? • Stigma • Style • Ovary • Female
T/F: Some seed plants are nonvascular. • False. All seed plants are vascular.
What group of plants produce “naked” seeds? • Gymnosperms
Name an example of a monocot. • The most common are grasses, corn, tulips, and lilies.
What are fronds? • Fern “leaves” or leaf-like structures
Which can live better in dry environments – seed or seedless plants? • Seed; seedless plants require water for fertilization
What group of gymnosperms are most diverse? • Conifers (the group containing pines, cedars, etc)
Which group of plants produce fruits? • Angiosperms
What is the difference between angiosperms and gymnosperms? • Angiosperms produce seeds that are enclosed in fruit • Gymnosperms produce seeds that are “naked”, often using cones
How long do perennials live? • More than 2 years
How are angiosperms useful to people? • Food • Medicine • Clothing
What is does structure D contain? • Xylem and phloem
What is required for seed germination? • The seed must absorb water
What passes through the stomata? • Gases (carbon dioxide and oxygen are the main ones we focused on)
What is the function of a root? • Absorption of water and minerals • Anchoring the plant • Storing food
What is the function of root hairs? • Absorption • Anchoring
What is dormancy? • When the plant stops or slows its growth • This is similar to hibernation in animals
